why are my foxglove’s leaves turning yellow?
Recently I planted a foxglove in my garden in partial shade. I live in Pennsylvania, so the summer is very hot with moderate rainfall. The plant's leaves are turning yellow, and I can't determine why. I have not fertilized the foxglove, but everything else around it seems ok. Any ideas?
Yellowing leaves on plants generally occur when there are watering issues.
Either to much or to little.
A newly planted perennial needs daily water, and even twice daily if temperatures are above 85 degrees.
Make sure you water around the plant crown. Don't water directly into the plant center, this can cause the plant to rot.
Well draining soil is very important.
