Are the leaves yellowing FROM THE BOTTOM? Are there brown spots or are the leaves getting ‘crunchy?’ If so, you probably have some sort of blight. Very common. Remove those bottom leaves, and give the rest of the plant a spray with a copper spray. It’s organic - kills all kinds of diseases.
If the leaves are just yellowing, with no die off or brown spotting, you may just be over watering.
Plants can be planted right next to one another and one is sitting in a pocket of clay, holding more water, while the other is not.
Every plant needs 1” of water a week. That’s it. If your plant is heavily mulched, and you think you may be over-watering, pull back some of the mulch and let it dry out for a number of days before watering again.
Good luck! :)
Thank you again for that information.
