Cacti come in a bewildering array of forms. These marvelous succulents have incredible adaptations to survive the inhospitable terrains they generally inhabit. Epiphyllum curly locks is an example of a cactus that uses its stems to capture more moisture and light. 

The plant has curly, curved stems which are the result of a mutation of a plant called Epiphyllum guatemalense. The name for this mutated cactus is Epiphyllum monstrosa. If you know someone with the plant, it is easy to learn how to grow curly locks from stem fragments.

Epiphyllum Curly Locks Info

Epiphytic plants live in trees and rock crevasses. The mother of the Epiphyllum cactus, curly locks, was from Guatemala. It was a plant that sprouted one or more abnormal curved stems. These were harvested and cloned to produce the crazy little cactus we propagate today. 

These plants are wonderful hanging basket specimens and make quite the conversation piece with their twisted, arching limbs. In nature, curly locks might be growing in a tree crotch or other almost soilless area. Epiphyllums are often called air plants because they do not rely upon terra firma as their growing medium. Curly locks have bright green, twisting stems. 

It produces 3 inch (8 cm.) wide white flowers with 6 inch (15 cm.) long tubes that open at night. This is because in nature it is pollinated by moths and bats, and these night animals can see the big white blooms easily. Oval, bright pink seedy fruits form once blooms are pollinated. 

These fruits are juicy and edible. The plant is also self-pollinating, and fruits can form even without the intervention of insects and mammals. Epiphyllum plants are often called orchid cacti.

How to Grow Curly Locks

Most Epiphyllum cacti are easy to grow from pieces of the stem. Allow cut pieces to callus for several days then plant into an appropriate medium. Make your own potting mix with three parts commercial potting soil and one part small to medium pumice. If pumice is not available, use bark chips or perlite. The soil must hold moisture but drain quickly. 

Keep the cutting in low light until it roots. Do not let the medium dry out but don’t let it get soggy either. The orchid cactus cutting needs to be installed 1 or 2 inches (2.5-5 cm.) below the soil at a serration. Rooting should occur in a couple of weeks and after that the plant really takes off, producing new curled stems.

The biggest danger is overwatering. The cactus needs to have moist roots at all times, but they should not be sitting in a dish of water. Make sure the top one third of the soil is dry before watering. In late winter, expose the cactus to cooler temperatures to promote spring flowering. Keep them in the basement or a garage for a couple of weeks to spur bud formation. 

The other biggest danger when raising Epiphyllums is lighting. Consider that these plants grow in thick forests in the understory and are used to dappled light at best. Just like any plant, they need light but should be protected from bright midday light. Morning sun is preferable with indirect light the rest of the way. If you find a spot where the cactus is happy, make sure to leave it there, as they do not like change.

 Use a 10-10-10 fertilizer diluted weekly during the growing season. In February, feed the plant with a 2-10-10 to promote blooming. Repot every seven years or so, but be warned, the plant only blooms when it is pot bound. It might be best to wait and see if you get flowers before giving the plant a new home.
