A fascinating succulent with tubular leaves in a coral-like formation. Just as easy as the commonplace jade plant to which it is closely related, and just as beautiful. Named after the hunting horn shape of the leaves.
By far the most common issue with Crassula horntree is overwatering, so leave a long dry phase between watering. These are slow growing, but long lasting. If you have the patience, then after a few years in a bright spot you will have a stunning individual specimen that will routinely produce delicate white flowers.
Temperature Fairly resilient against cold, but susceptible to root-rot if left wet in cold conditions. As long as it’s dry, it will be fine down to about 10 celsius, but if it’s wet then keep it as warm as possible.
WateringKeep it dry 90% of the time. This will take a much longer time in winter when the plant is in dormancy. When you do water, soak the soil completely. Often, the water can run down the sides of the soil and not get absorbed. In this case, water it slowly until it becomes absorbent or dunk the pot into a body of water and leave it there for several minutes until it is totally saturated.
Feeding Just feed once in spring, and once in summer. Being such a slow grower, it doesn’t need much help but you may find it helps in the production of flowers and staves off any other health issues it may have.
Tips Watch out for mealy bugs. They look a little like cotton wool, but they love eating this plant and will do it harm if left unchecked. The easiest way to get rid of them is with pesticide, but you can also use washing up liquid in water (the bubbles suffocate the insects) or simply wipe them off using a cloth.
Light Level Really bright and sunny, with spells of direct sunlight helping to not only stimulate growth, but also open up the leaves in their horn shape facing towards the sunlight.
