Q.Indian hawthorn shrubs
We just planted these shrubs and noticed that the flowers on some were turning brown. They also seem to be falling or leaning over. We water every other day as per instructions from the nursery we got them from. What can we do to fix this?
I would water daily, especially for the first two weeks of a new planting.
Soil should be moist, never dry or never soggy.
Pull the rock back so you can check the soil moisture.
Hardwood mulch application of 2 to 3 inches in depth will help with moisture retention.
Dropping means the plant is stressed and may be under watered, but if the soil is not draining the plant can also be droopy from lack of oxygen.
It's not to late, but do a bit of investigating and correct the issues.
