Is it OK to continue to use Miracle Grow fertilizer....?

...on trees (crape myrtle) and bushes that are currently blooming? The crape myrtle didn't bloom too well last year and is getting a late/slow start this year.

Is it OK to continue to use Miracle Grow fertilizer....?
Flowering trees and shrubs seldom need fertilizer once established. If you provide them with too much nitrogen in fertilizer, the plants will mainly grow leaves and not flowers.



Generally, one should not fertilize trees and shrubs in summer. The fertilizer will stimulate new shoot growth which may not have a chance to harden off before winter, leading to branch dieback.



So, if you are going to fertilize a flowering shrub, choose one with a low first number and higher second and third number and use it in the early fall when the plant is dormant, not in summer.
Reply:Sure, every 2 weeks with the full strength solution, every watering with a weak solution (1/4 tsp per gal of water.)
Reply:It is ok to use it on anything. I use it on roses.
