Getting Orchids Ready for Winter

1. It’s time to group and move orchids that need little water away from the rest of your collection. Maybe you can hang them under an eve or high on a shaded fence that the sprinkler system doesn’t hit.

2. Move adult orchids that haven’t bloomed in over a year into more, but probably not full, light. They won’t burn now and will adapt to increasing spring light.

3. Group young plants and tender plants so you can bring them inside when the thermometer goes below 50. You won’t like finding your scattered Rhynchostylis and Vandaceous in the dark with a cold wind chilling you. Dendrobiums won’t die at 40- 50 degrees but they will drop leaves and will need a year to recover.

4. If you can’t bring all your orchids inside if the temperatures are to be in the 30s or 40s assemble protection now for the plants you have to leave out. Fabric, but never plastic, covers over your plants will help and help even more if you have a soaker hose under the bench for vapor from our 70 degree tap water to rise and get trapped under the fabric.

5. You can begin to repot in February. Look over your supplies and buy what you need early this winter. If you wait you take a chance that your supply vendor will be out of something you need.

6. You can reduce the frequency of watering, and you can reduce the amount of fertilizer. Don’t even think about not fertilizing at all. After this summer cool weather sounds wonderful. It will be more enjoyable if you prepare.

Repotting triage

by Dot Henley

You realize you won’t get every orchid repotted that deserves to be repotted. What to do? Repot the most needy which would be these:

1. Any new orchid that you bought and that you have not repotted should be repotted. Many growers save labor costs by selling off the plants that need to be repotted. Furthermore the potting media used by growers probably won’t match what you use and will need to be watered differently.

2. Orchids with dying middles or leads probably have a rot beginning. Repot fast before you lose the whole plant. Cut off the sick/dying area and keep cutting with clean clippers for every cut until you reach clean tissue.

3. Orchids with established weeds need to be repotted to rid them of the weeds that will spread to your whole collection if you don’t stop them. IF you pull baby weeds EVERY week you won’t have established weeds.

4. Orchids that have an infestation of scale or mealy bugs should be repotted. Remove ALL the old medium, give the plant a hose bath unless it has very tender leaves, spray the nude plant with an insecticide, and repot the plant in a clean pot with clean medium.

5. Orchids that are giving off a foul odor and are not Bulbophyllums in bloom probably have rotten roots and need to have fresh medium.

Triage may let you delay repotting the less needy and YOU just became an “Orchid Doctor”.
