|About three weeks ago I planted a variety of shrubs, perennial and annual flowers in a newly created garden. I mixed topsoil (very clay like)from a local sand and gravel store with Miracle-Gro garden soil per the instructions. Now a few lower leaves on some of the flowers are turning yellow. Normally, I'd think I've over watered, but I don't think that's the problem since I've been hand watering just once a day. In addition to over watering that can sometimes cause leaves to yellow, what else could be the cause? I've spent a small fortune at Home Depot on the plants, soil and plant food so any thoughts/comments that may save the garden would be appreciated. Thanks. Julia|
|If only the lower leaves of your plants are yellowing, it could simply be a natural process. Plants tend to drop their oldest leaves in favor of growing new leaves and flowers. Since they have been in the ground for 3 weeks, you've probably seen the worst of the transplant stress (which includes yellowing and dropping foliage as the roots become established in their new homes). So, the yellowing leaves might be the tail-end of the stress. I'd continue to water deeply once or twice a week and pick off or snip off the yellowing leaves to make the plants look more attractive.
Best wishes with your new garden!
