Crepe Myrtle Watering Help
Can anyone offer up any advice on how to properly water crepe myrtles? I recently planted some in a new back yard (Mid July) and I want to make sure that I am correctly watering them. There are four trees and one shrub. As it stands right now all of them have a 1/2gph emitter to them and they receive 30min of irrigation every other day. The srub and three of the trees get some over spray from the sprinklers. I'm worried that I may not be watering enough. The shrub is fine but 3 of the trees look ok/ slightly stressed and one tree looks very water stressed. I gave it a good soaking and it seemed to perk back up. The problem is the soil here is very hard & non porous. It doesn't drain very well... water seems to pool up on it and then it will eventually drain in. Once moist the soil is very clay-ie and remains moist for a while. It seems like the top drys out but the bottom layers are still moist. Can anyone adivse me on how to properly water these trees and also when to fertilize them and with what?
