I bought 4 tomatoe planters in spring
and planted them in the ground, 3 of them have wilted and gone dry but I have one left.I watered them well every day but the last one left is still not doing very well, it is barely growing
, what can I do? Is it the soil? It looks a little bit too sandy for me, but I thought since I used pot soil around the roots that will help them a lot. I need advice, I don't want to lose the last tomatoe plant I have.
