I was given a couple of sweet potato plants for my birthday. I've never
grown such plants before. Any advice (ie best soil, depth etc?)

They need heat, a good depth of soft moist soil, and lots of room. Everyone
else will think you are growing bindweed on steroids so be prepared for the
comments. We grew them twice, the first time T & M sent the slips so late we
got only thin sausage sized tubers but we used them the next year to produce
the slips which we potted up months earlier and grew on in our heated
greenhouse. Much better crop that year but terrible slug damage made them
virtually unusable, not bothered again.
