During late spring, a little over 2 months ago, we planted 6 hydrangeas (3 on each side) in the empty flower beds on the front of the house. To cut down on weeds, instead of filling the flower beds with soil, we filled them with white lime rock.
I have read that lime works against the acidic level of the soil making it impossible for the Hydrangeas to change color, which is okay at the end of the day.
I am a bit concerned with the progress they have made. They were labeled as FAST GROWERS but they have not grown very much. I have also noticed a change in the leaf color, from deep green to a lime green. They have had a few blooms here and there, they don't wilt in the summer heat here in zone 9, south of Houston TX. I water them deeply about every 3 days. I purchased them from Lowes as FOREVER AND EVER hydrangeas, the two flanking the outter sides were Foil gifts for Mothers day. One is doing well with no new blooms, while the other is completely fried. I am considering of pulling out the ones flanking the ends and replacing with a creptmertlyes to give them more shade at noon. The front of the house gets good hot sun from about 7 am - 1:30pm and filtered light for the rest of the day.
What is your opinion on the wellfair of my plants? I don't know if being planted around lime rock is stunting their growth, or turning the leaves lime green. Also how much can I expect for them to grow? I can't see them from the road infront of my home.
Thanks for your opinions and help!
the two foil plants flanking the ends are having a hard time. The fried one gets after noon sun from a brake in the trees hovering over my roof on the right side. Underneath the fried leaves there are however new leaf buds. I do not think these will bloom anymore this year.
