Gardening is so confusing sometimes. Information can be extremely conflicting. I have a couple tomato plants where the leaves curled. Information says "not enough water" or "too much water". Ok...well how do I know which it is? "Look at the top of the soil, if dry water." "Don't just look at the top of the soil. Stick your finger in an inch and if it is damp it doesn't need water". Ok...what if one has a little bit if yellow on the leaves? "It's too close to the light." "It's not close enough to the light." Sigh...this is rough for a beginner like me.
