TERRESTRIALS: Problem Plants Use plastic pots, broad based, but half as high as most; repot any time during dormancy and carry over about one-third of the old compost to transfer the mycorrhiza; dormancy comes after flowering not in the fall or the winter as expected, so water lightly in summer, carefully in winter; practice at Kew; refer to OR87-19 0
