Orchid Care : Diseases – Crown Rot

In today’s orchid care post, I’ll be sharing a few tips on how to care for orchids with crown rot.  You may have seen plants at your local grocery store suffering from crown rot (I see it all too often) or perhaps you’ve had to treat an orchid with crown rot in your own home.  Treating crown rot can be extremely difficult, but the more we know about it, the better we can treat, even prevent it!

Orchids are susceptible to various types of rot including leaf rot, root rot and crown rot.  Monopodial orchids (Phalaenopsis and Vandas) are most suseptible to crown rot—a fungal infection that is caused by water pooling in the center (or crown) of the plant.

Crown rot can cause immense damage to an orchid and must be treated immediately.  One solution  is to use hydrogen peroxide (3%).  You can treat the crown rot with full strength hydrogen peroxide, repeating every 2-3 days until the rot no longer fizzes and bubbles with the hydrogen peroxide application.  Sprinkling cinnamon from your kitchen cabinets can also be used to treat the fungus.

Of course, prevention is the best medicine, even when it comes to orchids.  Crown rot is 100% preventable.  Water your orchids early in the day, so that the plant has time to dry off before night time and provide your plants with proper air circulation.  Most importantly, always take the time to inspect the crown of your orchids regularly.  Take a tissue and soak up any water that has pooled in the crown.

(If you do decide to remove severely damaged orchid leaves, make sure you sterilize the blade for each cut.)

It looks as if I have purcased a phal with crown rot, will try your solution with H2O3 and cinnamon and hopefully save this plant. Please add me to email mailing list.

When treating w hydrogen perox….just dump it full strength in the middle of the plant? Thanks
