Does anyone know what is the minimal depth needed to successfully grow sweet peas in troughs as the south-facing side of our house is ideal for them.

I haven't grown them in containers, but logic suggests that the deeper the better, and I'd guess perhaps not less than 10-12". They are large plants which will need a lot of feeding and watering, and the smaller the depth then then more likely they are to dry out and become stressed.

Yup, I agree with that. Thanks.
