Wilsonara with Withered Pseudobulbs: Pot Mix Particle Size Issue

One Huge Growth, Three Shriveled Bulbs—Mix Too Coarse

Wilsonaras have FINE roots. Medium bark = too large particles → roots dry out excessively.

Now: Mix in seedling mix/perlite (don't disturb new growth roots).
Next repot: Use finer mix or blend.
Check deeper: Old mix at bottom may be degraded → root rot → shriveled bulbs.

Large new growth = excellent potential. Fix the root zone moisture balance, and this plant will thrive.

Vickie, particle size matters for fine-rooted orchids. Adjust and watch it take off.
