Liquid tomato food... all the instructions are on the container.

I agree with MG,but don't feed till your tomato's have formed,to the size of small marbles.I don't know what other members do,but I only water the soil,when feeding,and not the plant....

Oops thanks Bloomer forgot to add that! We water from the bottom.

YW,Mg,I forget lots of things Lol.But to be fair,Guest didn't really ask that,so just me adding a bit...

lol
