Install posts at either end of each row, each with two sets of T-bars, one 6 inches from the top, and another a foot from the soil line. This arrangement will allow you to tie the canes up to the wires as well as keep them out of the way as you move down the row. We normally destroy the mother plant after allowing one runner to root in the summer of the plant's first year. But if the same plants have been left in place for two years, it's time for them to go. It's also a good idea to change the location of the bed.
Strawberries are subject to many soil-borne diseases and insects.
If you grow strawberries in a three-tier arrangement, as I do, change the soil, using the old soil in the coldframe or as potting soil. Prune hybrid tea roses, removing weak and crossing stems. Shrub roses are pruned in the same manner as shrubs, taking out one or two canes to the ground each year. Strong, new canes will replace these. Don't lop off tips.
