I've had my Vanda Orchid for about 3 months, When I bought it, it had 6-7 flowers with lasted a few weeks, now its got no flowers just leaves and there are what look like fresh roots, do i need to keep them moist with a spray bottle or carry on as normal....?
Your new roots look great. At this stage they will benefit from frequent mistings. They should be watered enough to turn green and then allowed to dry between waterings. Watering like this three or four times a day will promote their growth and encourage new roots to emerge and grow.
