Devil’s Backbone Care Guide
Here’s a complete guide to help you grow your Devil’s backbone plant indoors or outdoors.
Devil’s Backbone Plant Light Requirements
The Devil’s backbone loves bright indirect sunlight. Placing it in the stinging hot rays of direct sunlight might cause its leaves to burn.
If you place your plant outdoors, put it somewhere it gets partial shade. Avoid direct sunlight except in the winter.
If you live somewhere with cold weather but not frosty, place it in the direct sun but avoid too much sunlight. If your plant is variegated, the white portions of its leaves will turn pink.
Devil’s Backbone Plant Water Requirements
The zig-zag plant stores water in its juicy stems. That means they are easily prone to over-watering.
We must ensure that we do not water our Devil’s backbone plant too often because that would lead to root rot. Instead, it would help if you waited for the soil to dry completely between waterings.

Devil’s Backbone Plant Soil Requirements
Jacob’s ladder is a succulent plant. That means we must ensure it has well-drained soil. It does not like its soil moist. However, it does like it to be nutrient-rich.
We must provide adequate drainage if we want our potted plant to remain happy. For that, drainage holes are vital. Also, our soil mixture must be specially designed to drain quickly while retaining the right amount of water.
The best quick-draining soil has sand mixed or crushed gravel or vermiculite for air circulation. Here is the ideal soil mix for the Persian lady slipper:
- 30% Garden Soil
- 25% cocopeat
- 2% Vermicompost
- 20% Perlite
You can switch out each ingredient in the potting mix for an alternative. For example, you could use peat moss instead of cocopeat or compost instead of garden soil.
Find whatever is easier to access in your local area or garden store. Remember to add a few larger pebbles at the bottom of the pot.
That way, the water drains out excess moisture effectively.
If you do not wish to mix the potting soil yourself, you can buy good houseplant potting soil instead. Be sure to ask the gardening store or nursery for something quick-draining and nutrient-rich.
Devil’s Backbone Plant Fertilizer
The Devil’s backbone is a hardy plant. It will grow well with very little fertilizing. You can use slow-release fertilizer pallets in the soil or top dress with fertilizer powder.
