is there any type of fertilizer to use on shrubs? like azaleas
I use Arbor Green for all trees and shrubs. This is injected into the rootzone. For acid loving plants like Azaleas, rhodo's, holly, etc., I'll add in some aluminum sulfate.
where can i buy that type of fertilizer. Is there any type of granule based fertilizer i can use
Ammonium sulfate (21-0-0) can be purchased at lesco. A complete fertilizer, high in phosphuros, should be applied in the spring and fall.
I use an 8-10-10 for bloomers. Usually hitting azaleas in the fall to help form and set the bloom for the spring.
10-4-10 with minors for greenery type trees and shrubs.
We apply once in the spring and once in the fall.
We get ours from Howard Fertilizer. We have been using their brand for the last 9 years and have been very happy with it.
Lesco. They also had a Landscape and Ornamental fert at one time, which was all slow release granular. I don't know if they still make it or not. It worked pretty good. I use the Arbor Green because I can add micro's, insecticdes, etc. to my tank along with the fert., if needed.
any problems with the arbor green settling in the tank?
definately need mechanical agitation, right?
Oh yah, it'll settle out pretty quick. Mechanical agitation is a must!
Lesco Landscape and Ornamential 14-14-14 all slow release
That would be ok, but the one I remember was like a 12-26-16, or something along those lines. It had much higher phosphorus and potash.
