Use the Correct Iron During the Summer Months

Q. I was told I need chelated iron for my roses..So  per instructions added the granulated type today..My question is how often do I do this?.They do not mention this on the label, just the dosage.

A. The soil applied chelated iron is not effective this time of year (summer). It should be applied once in January or early February just before new growth or shortly after it begins. Iron does not move inside the plant once growth has stopped. The only iron effective now on older growth is the iron applied to the leaves as a liquid spray. This liquid spray enters the leaf directly rather than up the inside of the plant from the roots. This is the one you should use after the big flush of spring growth.
It is 8 dry oz and sells for $5.20 and makes 50 gallons of liquid spray
Use distilled or RO water and a wetting agent such as  EZ Wet to help it move through the leaf surface
EZ Wet is a surfactant cold pressed from agave which helps make sprays "wetter" by reducing their surface tension. This helps sprays move inside the leaf rather than run off onto the ground
$20 per quart. Use 1 to 3 oz in 5 to 10 gallons of spray

You can get this one at Viragrow in North Las Vegas. Use distilled water when you mix it with water and a wetting agent like 1 tsp per gallon of dishwashing detergent but the commercial wetting agents are better such as EZ Wet. Apply it until the solution drips from the leaves. Repeat every 4 or 5 days for three or four applications.

Star Jasmine LOVES Compost!

Q. We have star jasmine on both sides of the house. You mentioned adding compost to the plants and you mentioned Viragrow. Where are you located? We had trouble findingit.

A. The compost that Viragrow carries in North Las Vegas is called Viragrow compost. They carry two types of compost; one that has about 15% biosolids in it and the other is biosolid free. Both make very good soil amendments and can act as a slow release fertilizer as well.
Viragrow compost is straight, 100% compost. Use as a soil amendment or slow release fertilizer
It comes in bulk and also now in bags but the bags do not say compost on them. There was so much demand for it in small quantities that they started bagging it. They used some leftover bags for bagging the bulk compost. I think the bag says soil mix or something like that. 
Viragrow compost might come in either of these bags since leftover bags were used
Apply about 1/2 cubic foot per plant around the base, near the stem but not touching, and water it in. Apply it once a year and see the difference compost makes.

I am up there on Tuesday, Thursday and Fridays in the morning as their consultant to help homeowners with product selection and talk about any problems they might have. Feel free to stop in at that time if you want to talk with me about it.

The company, Viragrow, is located near Cheyenne and I 15. Exit I 15 and drive west to Losee Road. Turn north on Losee until you get to Colton, the first stoplight, and turn west and then an immediate north on Bruce. Viragrow is on Delhi St. which runs into Bruce.

Why is Steam Coming from My Compost?

Some people think that steam comes only from compost which is too hot for plants. When temperatures are cool, warm compost can create steam but is still safe to use when planting. Know the temperature of your compost. This is why Viragrow posts compost temperatures directly on its website.

How to Plant in Raised Beds Using Compost

Q. I am going to till up a new area for a vegetable garden. The soil is high clay content "good old desert dirt". Beside the obvious generous addition of compost, what else do you recommend to improve the soil? Washed sand, gypsum, greensand, steer manure? All of the above, none of the above? I thank you in advance for your answers, :)

A. If you add compost you wont really need anything more. I am sure some others have their favorites to add but the backbone is the “black gold” of the compost. The amount of compost depends on the organics in the soil to begin with. This can be judged oftentimes by soil color. A very light color usually indicates very low organics and I would add about 50/50 compost with the soil. If the soil is darker then you can add less. I would make raised beds. You can do this without sidewalls.

I attached two information sheets I wrote for Viragrow. The planting calendar is a general calendar and don’t take it as gospel. Just a guideline. It is for Las Vegas so adjust it accordingly. The calendar also has some instructions on making raised beds without constructing sidewalls. The other information sheet is on planting in compost rich soils and avoiding some possible burning of transplants and seeds during the summer months.

Cut Back Difficult Plants to Get Them to Change

Q. This is the 8th year for our honeysuckle plants and, although they appear healthy, we cannot get them to produce blossoms. They do get one or two blossoms each year but do not produce massive blossoms. Tried various fertilizers to no avail. What can we do to stimulate blossoms?

A. I also had a problem with honeysuckle not flowering many years ago. We have a basic tenet in horticulture. When a plant is not doing well or not what we want, cut it back hard. I did that with honeysuckle and it started to bloom. 

I don't think it will be a special fertilizer or anything else. Make sure it gets fertilized once or twice a year, usually in the spring and as early as February. Make sure it gets plenty of water. This is not a desert plant but it can handle our extremes. 

To improve it's looks, add a half a cubic foot of compost to the base of the plant and watered in thoroughly. You can do that now. Viragrow in North Las Vegas has compost available for $2.50 for one cubic foot bag. I consult with them but that is the best compost available and it will improve the health of plants if they are struggling due to soil problems.

Mulch and Sprays Reduce Black Fruit Rot on Tomato

Q. I planted tomatoes in late feb. in  my raised boxes..The cherry tomatoes have been doing great.. producing almost more then I can handle.The neighbors are enjoying the excess..However the larger varieties  develop  good size fruit but as they ripen  start to turn black on the bottom..making them unusable.. Any ideas or suggestions ??

A. This is a physiological disorder (not a true disease caused by a pathogen) called blossom end rot. It is suggested that it is caused by irregular soil moisture causing calcium deficiency. Here is a nice discussion by Bonnie Plants

Use mulches to reduce water stress. I like the horse bedding pine shavings you can find at Viragrow.

Calcium sprays might help such as Monterrey's Tomato Blossom Spray available from Viragrow.
Lawn & Garden Products LG 7236 Tomato Blossom Spray 16oz.
Some varieties of tomato or more prone to blossom end rot than others. Keep track of the varieties you are growing and try different ones. It should improve later in the season.

Viragrow Has Rock!

Because of several requests regarding rock mulch, Viragrow now has rock for its customers. Remember, rock mulch is not organic so covering the soil around plants with rock mulch will slowly (in three to five  years) deplete the organics in the soil.

For a decorative look, instead of rock, use wood mulch such as "Gorilla Hair" or Sequoia Blend found only at Viragrow. These organic mulches are very popular with landscapers and hotel gardeners for that very "finished" and decorative look.

Compost, unlike soil mixes, contains no sand or "filler". It does not add bulk to a soil but improves soil and root health. It is always best mixed with the soil at the time of planting. But it will also slowly improve soils when added to the soil surface near water.

Apply 100% compost to the rock mulch WITHOUT MOVING THE ROCK. Apply it near drip emitters or wherever the soil will be wet. Wash it into the soil with a hose. It will wash through the rock and on to the soil surface. As long as the soil becomes wet it will continue to "feed" plants and improve the soil.

Using Steer Manure to Replace Compost?

Viragrow carries Red Star Steer Manure
at $2 for a 2 cubic foot bag or
$1 for the Garden Gourmet steer manure
in one cubic foot bag
People are coming to Viragrow and telling me they are buying steer manure for their garden rather than compost. It's okay to do that and you might save maybe one dollar per cubic foot but let's understand the difference. If you are going to do that, do it the right way and understand that steer manure is steer manure and compost is compost.

The usual terms applied to packaged steer manure is "aged". Fresh steer manure contains lots of urea which is "too hot" for plants and can burn or kill them. Aged manure has the urea lost or volatilized as ammonia (ever smell ammonia in a feedlot?). The urea not lost as ammonia is converted by soil microorganisms into nitrogen "fertilizer".

Manure has stuff in it besides urea. The manure varies in nutrients depending on what the animal ate. The quality of a steer manure is directly related to what the animal was fed.

"Aged" steer manure is dried manure. It has not been composted. The composting process takes manure and plant waste high in carbon and converts it into humus. Humus is the "black gold" that experienced gardeners value. Steer manure is steer manure. It is not compost. It does not contain humus. Buying steer manure and calling it compost is like buying eggs and calling it an omelette.

If you want to convert a bag of steer manure into compost you can. Mix it half and half with wood
shavings or pine bedding or straw or shredded newspaper, put in the shade, keep it moist and not too wet and turn it when the inside temperature of this pile reaches 160F. This temperature kills the microorganisms, good and bad, in this mixture. Cow poop WILL have E. coli in it. Dried cow poop can have living E. coli in it for months after it has been dried.

Cow poop is not safe to handle (unless you take precautions just like it is poop) unless it is composted. Turning the compost pile reintroduces the good microorganisms back into the pile and re-inoculates it. They grow again because of the rich mix, dominate the bad microorganisms.
Viragrow Compost. $2.50 per cubic foot

Continue to turn it, over and over, when the temperature reaches 160F and don't stop until the temperature starts dropping. Once it starts dropping the compost is "finishing" and

turning into humus, "black gold".

OR you can pay $1 more per cubic foot and have Viragrow do it for you. Your choice. I think a buck is pretty cheap for all that work.

My Palm Leaves Have Brown Spots

Q. My fan palm has black spots on the fronds.  Someone said it may lack iron.  Or, is it getting too much water?

A. Without seeing what the fronds look like I will assume it is a nutrient deficiency such as iron which is a common to desert soils. Nutrient deficiencies occur for a variety of reasons, not simply because it’s missing or unavailable in the soil.

I doubt it is a leaf disease because we have such dry weather in the desert.

First on the list of reasons is, of course, the soil. There is a lot of bad soil surrounding homes. Soils supporting the growth of palms should be amended with organic materials such as compost in a 1:1 ratio at the time of planting.

Most landscapers and homeowners don't use enough compost or don’t use substitute a soil mix instead. Soil mixes are not compost. They contain mostly sand.

Compost disappears in about 3 to 4 years if the soil is covered in rock mulch and nothing is done to add more. As a result, the soil becomes compacted, drains poorly and begins suffocating the roots of plants like palms. As roots die, these nutrient problems emerge as black spots on leaves even when fertilizer is applied. Black spots appear first on older fronds. As this condition progresses, it is seen on newer fronds.

People see palms declining in health so they give it more water. More water suffocates the roots even further and more roots die. In a slow death spiral, black spots on the fronds graduate to fronds turning yellow.

Because they are weakened, palms may become susceptible to diseases like Fusarium. Because roots are dying, palms cannot pull nutrients like iron out of the soil and the plant becomes deficient.
Amending poor soils at the time of planting and covering this soil with wood chips instead of rock improves the soil and adds nutrients as it decomposes. Organics from decomposing wood chips applied as a surface mulch improves drainage, adds nutrients and helps drain water away from the roots. The soil health improves and more critters inhabiting the soil are seen including earthworms.

Adding iron fertilizers to the soil may help in the short run. The same is true of iron applied as foliar sprays to the fronds. But water and poor drainage may be at the core of the problem and can only be corrected permanently with additions of organics like compost and wood chips as a surface mulch.

Other nutrients can cause black spots on the leaves such as potassium and magnesium deficiencies. The same approach will help with these nutrients as well.

Butterfly Iris Are Not Desert Plants and Need Improved Soils

Q. A number of these plants are in the backyard.  The tips of the leaves have a burnt or dead appearance.  Is there something I should be doing for these plants?  They are occasionally fertilized with general Miracle Gro plant fertilizer (a few times per year).

A. This may be butterfly Iris, I'm not 100% certain but it doesn't really matter, the problem is the same. They don't like desert soils all that well so it is best to grow them without rock mulch. They like soils with more organic matter in them. If I'm correct and it is butterfly Iris, they are native to Africa and are sometimes called African Iris.

The leaves can turn brown at temperatures below 25° F. They are removed either by pulling or cutting at the base. Some plants that look like this have leaves that can be pulled easily while others do not and they must be cut off close to the base.

About every three or four years the plant should be entirely dug from the ground and separated or divided when they are too large. When they get large, you don't see as many flowers and they are not as vigorous. They don't look as good. They can tolerate a little bit of dry soil but they really like wet soils better.

They don't like full sun but they prefer filtered light such as the light beneath trees that are not overly dense.

So, in short, I would lift it from the ground and divide it. It is easy to do because they are growing in clumps. You simply cut these clumps apart and replant a smaller clump in the same place. But this time add an equal amount of compost to the soil when you're replanting it. Instead of using rock mulch, use 3 to 4 inches of wood chips. When you are dividing them, remove the brown leaves at the base. Keep the roots moist but not overly wet. Lightly fertilize 3 to 4 times a year.

The Best Fertilizer to Use for Lantana

Q. What is the best fertilizer to use on Lantana?  I have yellow and purple and the yellow just never seems to keep the flowers long in the summertime, they come and go and do no not look very vibrant.  I am afraid of some of the fertilizers after too much fertilizer wiped out some other plants of mine in the past. Is there such a thing a a mild fertilizer to use? 

Yellow lantana flowers
A. For pushing new growth you want something high in nitrogen. For flowering, you need something high in phosphorus. For overall plant health potassium is good. For "mild" fertilizers use fertilizers with smaller numbers or slow release fertilizers.
Even though some of the numbers are fairly high, this is a relatively "mild" fertilizer because the first number, nitrogen, is low. Fertilizers with a high first number can be damaging to plants if too much is used. This fertilizer is called a starter fertilizer because it is high in the middle number, phosphorus, which stimulates root growth, important for new transplants and seedlings. This fertilizer blend is $18 for 15 pounds.

So if you are looking for an inexpensive fertilizer something like a 16 – 16 – 16 is okay or 20 – 20 – 20 or anything with all three numbers the same.
This is a water-soluble 20-20-20 intended to be an all-purpose fertilizer that promotes leaf and stem growth, flowering, rooting and overall health. This 5 pound bag sells for $9.80. Compare that price with MiracleGro, also a water-soluble fertilizer.
Another option is to use straight compost but you have to use a lot of it compared to a fertilizer. The fertilizers I mentioned, probably one handful of fertilizer is all you will need and water it in heavily. You can also use water soluble fertilizers like miracle grow or peters. You mix the fertilizer in a bucket of water and pour it around the plants.

Viragrow compost is rich in nutrients and microorganisms. It can be used as a fertilizer around fruit trees, ornamental trees, shrubs and even your lawn. You will never see a darker green color for a lawn then you well when applying compost as a fertilizer. Bulk viragrow compost sells for $43 for cubic yard. It is also available in one cubic foot bags for $2.50.

With compost you would probably apply one fourth to a half of a cubic foot bag and water it in. The compost or composted manures will give you the best results. The fertilizers I mentioned will also work very well. So it is your choice which you want to use. 
Compost can be applied directly on top of wood or rock mulch and watered in with a hose. Compost not only feeds the plants nutrients but also improves the soil. With desert soils that is extremely important.
But I am talking compost, not a soil mix. They are totally different. You can get bags of compost for about $2.50 for one cubic foot bag at Viragrow in North Las Vegas. Soil mixes you can get anywhere. Fertilizers that work you can get anywhere.

The Old Photinia Yellowing Problem

Photinia with yellowing and leaf scorch due to iron chlorosis. 
Q. I have a bank of Red Tipped Photinia of about 25 feet. They are 10+ years old. Two years ago they started turning yellow with brown edges. I have been everywhere and they say take them out. One place in January suggested adding 16-8-4 which I have done twice. Now they tell me to wait until late April to add anything else.

A. There are two problems going on; the soil is being depleted of organics and the photinia has developed iron chlorosis. To keep photinia dark green, both of these need to be present. This happens to photinia planted in our soils as the organics in the soil run out, usually in five years if none is added. It is worse if the soil around them is covered in rock mulch.

EDDHA iron chelate
1 lb  $14 / 5 lb $48
Put a layer of Viragrow compost around them along with iron chelate that is EDDHA.  Each plant should get about 1 to 2 tablespoons of this chelate sprinkled on the soil around them and watered in. Use about 2 to 3 cubic feet of compost around each plant Apply the compost to the soil and water that in as well.

Existing leaves will not turn green but leaves emerging after the chelate is applied will. The only way to get yellow leaves green again is to spray them with iron or cut the plants back and let them regrow after applying compost and iron EDDHA.

Bottom line, your photinia needs iron and improved soil.  the EDDHA iron along with compost and a normal, once a year fertilizer application. By the way, wood  chip mulch makes a big difference!!

Add Compost to Raised Beds Every Year

Q. I have a 500 SF raised bed garden.  I would like to add Viragrow compost to it this year.  My soil is pretty good.  How much should add?  I usually rototill in 20 1QF bags of steer manure every other year.

Yes, Viragrow has bagged steer manure
but compost is better for raised beds
2 cubic foot bag is $2.00
A. You can use steer manure but compost is more effective because it has already been broken down and the nutrients readily available to plants. It also helps the chemistry of the soil benefit plants.

When you apply steer manure it has to break down in the soil first before it can be used by plants. It can be effective but it takes longer. Compost is a better product because it is a combination of animal and/or green manures and plant products that have fully rotted or composted.

Composting releases a lot of humic and fulvic acids that are considered the "black gold" of gardening. It is an improved product over using uncomposted manures. Compost is also a safer product than untreated manure because commercial compost must be free of human pathogens because of the heat generated in commercial composting.

            I am using a calculator for determining eating how much compost you would need on a 500 ft.² raised bed garden. You can find this calculator on the landing page at the Viragrow website .

Viragrow has bagged and bulk compost.
1 cubic foot bag is $2.50. I cubic yard is  $43
For raised beds that were productive last year, I would recommend a 1 inch layer of compost applied to the surface of the raised bed and mixed into the raised bed as deep as you can, at least 8 to 10 inches.

You should do this to a garden area every year since compost breaks down and totally disappears in about three years. In the first year of actively gardening about 40% of the compost content of a raised bed is used up.

If it has been three years or longer since you've added compost, I would suggest you consider a 2 inch layer of compost and mix it into the raised bed. You can tell how much compost you need by how easily the soil in the garden digs.

If it has been a year but your raised bed digs fairly easily, put down a 1 inch layer. If it has been longer and the soil is pretty compact and harder to dig, then put down a 2 inch layer and mix it in. Be careful, because you can add too much compost to a raised bed.

Viragrow has phosphorus fertilizer.
20 lb is $18.20
            A 1-inch layer of compost applied to 500 ft.² would require about 1 1/2 yd.³ of compost which is about 40, one cubic foot bags.

But remember, if you are using good quality compost this compost application will substitute for several months of fertilizer applications. Once you put compost into your existing raised bed, very little fertilizer is needed for the next 3 to 4 months.

After about three months, side dress or dribble a high nitrogen fertilizer 3 to 4 inches from a row of vegetables and water it in. When putting in transplants or planting from seed, always add a small amount of phosphorus to the soil around the seeds or the soil used when planting the transplants.
