Best Way to Prune an Orchid

by

Pruning orchids is essential to promote healthy growth, encourage flowering, and maintain the plant’s overall health. Here’s a step-by-step guide on how to prune your orchid correctly.

Part 1: Trimming Off Dead Stems and Roots

  1. Sterilize Your Pruning Shears
    • Why: To prevent the spread of diseases.
    • How: Dip your pruning shears in rubbing alcohol for 30 seconds. Open and close them to ensure the alcohol touches all surfaces. Set them to dry on a paper towel.
  2. Wait for All Flowers to Fall Off
    • When: Don’t prune while the orchid is blooming or if healthy flowers remain on the stem. Prune only after all blooms have fallen off.
  3. Cut the Stem Down to Soil Level if It’s Brown
    • When to prune: If the orchid’s stem is brown or yellow and shriveled, it won’t produce more flowers. Trim these stems all the way down to the soil level using sterile pruning shears.
  4. Trim Dead Roots
    • How: Gently remove the orchid from its pot. Cut any brown, soft roots (which are dead) while leaving firm, white roots intact. This helps prevent root rot.

Part 2: Pruning to Encourage Flowering

  1. Sterilize Your Pruning Shears Again
    • Why: Ensure clean, disease-free cuts each time you prune.
  2. Check the Orchid’s Health
    • What to Look For: Healthy, firm, green leaves. If the leaves are limp or yellow, let the plant recover before pruning.
  3. Identify Dormant Eyes on Stems
    • What Are They: Small brown or beige spikes, which can develop into new stems or flowers. Look for these dormant eyes before cutting.
  4. Locate the Second Node Below Where Flowers Bloomed
    • What is a Node: A thickened area or brown line on the stem, which holds the potential for new flower spikes.
  5. Cut 1⁄2 in (1.3 cm) Above the Node
    • Why: Cutting above the node helps encourage new flowers without damaging the potential flower spike. Ensure not to cut into any dormant eyes on the node.
  6. Wait for New Blooms
    • When to Expect Flowers: Typically, orchids will bloom within 8-12 weeks after pruning. If there’s no sign of flowers, try lowering the temperature to stimulate growth.

Part 3: Caring for Your Orchid After Pruning

  1. Repot the Orchid if Needed
    • When: If the orchid has outgrown its pot or roots are cramped.
    • How: Choose a pot that’s 2 sizes larger than the current one and use orchid-specific, well-draining potting soil.
  2. Provide Adequate Light
    • Where: Keep your orchid in an east or west-facing window. Orchids need bright, indirect light to thrive.
  3. Watering
    • When: Water when the soil feels dry. Stick a finger or wooden skewer about 1 inch (2.5 cm) into the soil to check moisture.
  4. Fertilizing
    • How: Fertilize with an orchid-specific fertilizer for 3 out of every 4 waterings. Use plain water on the fourth watering to prevent salt build-up in the soil.

Final Tips:

  • Prune your orchid to maintain its health and ensure beautiful blooms.
  • Always sterilize your tools to avoid plant diseases.
  • Regularly check for root health, repot when necessary, and care for your orchid’s light, water, and fertilizer needs.
