saving a dendrobium with really less number of roots

[Roberta]

Many Dendrobiums lose leaves routinely, to grow new ones in the spring. With inadequate roots, even a non-deciduous one may shed leaves to reduce water loss. then, in spring the new growth will produce new roots. Do you know which Dendrobium this is? For now, just patience. Two weeks is nothing in the life cycle of an orchid. If it does grow, it will likely be several months before you see progress.
