I have inherited a small garden plot from a man who was studying for his horticulture doctorate. He was experimenting with the soil and I believe it might be the cause of my problems. All of my plants grow very slow. I have tomatos that are finally getting large but still do not flower or produce tomatos, Bell peppers and cayene that will not flower or produce peppers, and cucumbers that should be much larger than they are now. My boyfriend seeded his cucumbers at the same time and his are 4Xs the size of mine. Is there anything I can do to help these poor struggling plants? They look nice but just aren’t growing as they should much less producing anything.
