yes. or move the bed as part of a 4 yr rotation, so one bed getting going, one 2 yr bed in full production and one tailing off. they will live more than 3 years but the crop drops off.
according to LDH the august planting gives the best crop in next summer, use 2lb of bonemeal to 4sq yards, plus loads of compost, line the trench with feathers or daggings. plant through straw, or weed membrane.
2 years ago i made my strawb bed, and planted wild ones in with the cultivated, this year ive been eating the hybrids. their about twice the size of wild ones but still as tasty. but not very many of them. ill collect the seed this year and see what i end up with, its quite exciting!
