How to Grow an Orchid Cactus

Orchid cactus flower

The orchid cactus, also known as epiphyllum, is a genus of cacti that grow as native plants in the jungles of Central America. Natural orchid cacti have white or yellowish flowers that bloom at night. They are picky plants that require routine maintenance and a specially made potting soil. Follow these easy steps to grow a healthy and beautiful orchid cactus.

Things You'll Need

• Peat
• Crushed lava rock
• Coarse sand
• Planter
• Rooting hormone
• Sea kelp fertilizer
• Pruning shears

Instructions

1. Mix one part peat, one part crushed lava rock, and two parts coarse sand in a planter with holes in the bottom. This is richer than typical cactus soil and will also allow proper drainage of water.

2. Take a cutting from an adult plant and dip in rooting hormone. Allow the cutting to sit out for up to two weeks or until it has completely scabbed over. Pot the cutting in peat mixture afterward.

3. Keep peat mixture moist but not soggy. Water thoroughly, allowing the excess water to drain through the holes at the bottom of the planter. Water when the top third of the soil becomes dry and immediately after blooming. During winter months, water only enough to keep the soil moist.

4. Fertilize the orchid cactus during spring, summer and fall, using sea kelp fertilizer. Never fertilize during winter months. Always keep the cactus at a temperature between 45 and 70 degrees Fahrenheit.

5. Use pruning shears to remove all dead foliage from the orchid cactus. Keep the plant in a sunny window or in a shady area. Never place in direct sunlight or extreme heat.

Tips & Warnings

• The orchid cactus blooms during the spring and summer months. Airy, well-ventilated rooms are ideal to grow an orchid cactus. Outside in temperate locales is also favorable, but never set the plant in direct sunlight. Vermicompost or a well-balanced fertilizer can be used in place of the sea kelp.
