If you want to know whether you are caring for your Phals correctly, you have to evaluate their health on a regular basis.

Signs of Healthy Orchids

  • Orchid leaves are thick and rubbery
  • Leaves are uniformly green, and not mottled
  • Colors in the blooms are robust

  • White webbing on leaves
  • Leaves are yellow or have brown edges
  • Very dark green leaves
  • Limp, wrinkled, or torn leaves
