Yellow leaves can also indicate overly acidic soil (chlorosis). Dump some coffee grounds in the soil to lower the ph. Tomatoes are very heavy feeders and anything that reduces their ability to take up nutrients (like the wrong ph) affects them quite a bit. What kind of soil are they potted in?
I need to take a look at what's left of the two bags of potting soil that i used - can't remember the brand, but the nursery thought it would be fine for tomatoes.
I suspect overwatering. I have made the same mistake--I bought the seedlings late and they needed daily watering at first and I extended that too long. I suspect they can be saved by cutting back the water now.
How often do you water them?
ReplyDeleteDaily, pretty much, since they are in pots and the soil goes dry pretty fast.
ReplyDeleteI'm convinced we have overwatered them. There are yellowing leaves that match photos on the web of overwatered tomatoes.

ReplyDeleteI think I may have mistyped. Tomatoes like acidic soil. The yellow leaves indicate an alkaline soil. Oops!

ReplyDeleteThanks! We are holding off on water for a bit - I suspect that we have been overzealous.
