How to Save an Overwatered Christmas Cactus

Christmas cactus, Schlumbergera spp., is a Brazilian rainforest plant that grows in the dappled sunlight that penetrates the tree canopy.

It is an epiphyte that needs something to cling to for physical support, like a tree or rock.

Suited to outdoor cultivation in USDA Hardiness Zones 10 to 12, Schlumbergera makes an easy-care houseplant in all regions.

Our guide to growing Christmas cactus discusses all you need to know to grow one.

This article zeroes in on ways to avoid overwatering a Christmas cactus and how to go about saving one that is too wet.

Here’s what we’ll cover:

Let’s get started.

As a rainforest native and not a desert dweller, Schlumbergera prefers consistently moist soil.

However, needing ever-present moisture does not mean you must constantly hydrate a plant. Watering when the top third of the soil is dry, generally every two to three weeks, provides the required moisture.

A deep soaking before the soil dries out mimics the conditions in these species’ natural habitat.

When you water, continue pouring until it runs from the drainage holes in the bottom of the pot. Water a second time to moisten any remaining dry spots, and drain thoroughly before returning the pot to its drip-catching saucer.

Reduce hydration during the six to eight weeks prior to Christmas at the end of December as part of a regimen to simulate dormancy and stimulate blooming.

During this period, instead of giving it a good soaking every few weeks, lightly moisten the soil when the top inch is dry.
