Hi, You come highly recommended, so I'm asking you: I planted a cherry tomato plant, about 6 inches tall. Not it's about 2 feet. Has flowers and fruit already. It's in a 4x4' container - urban deck garden bed - with compost, peat moss and vermiculite. It's on its second year. This year, I have another tomato plant, lots of strawberry plants, borage, cucumbers, onions, herbs. All are doing very well, but the cherry tomato plant developed bright yellow leaves, from the bottom now up about half way. My gardener friend suggested removing the yellow leaves and stems because he thought of fungus. The place where I bought the plant thinks either over- or under-watering. I diligently water the bed, and it has a felt liner, and sits on a plastic sheet that is not attached to the structure, so water can drain. I added some Miracle Gro two days ago. The part with flowers and tomatoes looks good, and when I removed the leaves and stems, they felt "plump" as if well-watered. I don't see any evidence of undrained water. Can you help??
