These plants are in 4″ baskets and we estimate them to be 1-3 years from bloom size. They will produce large, pink flowers.
Vandas like to be in a very bright area and watered often. We water ours daily in the summer months and 3-5 times per week in the cooler months, always with weak fertilizer. They are heavy feeders, but reward by blooming often when happy.
As a rule, Vandas do not like to be potted. We start ours out with a small bit of bark to anchor them, and let the roots grow out where they may.
