Torch Cactus Care

Woolly cactus prefers a well-lit area and well-drained soil. With a lack of sunlight, you risk not seeing the amazing Torch cactus flower, since the plant simply will not bloom. You can make a suitable drained soil yourself by mixing sand, peat moss or compost, and fine gravel. When it comes to watering, this plant needs the same conditions as most other succulents. This is the case when it is better to under fill than overfill since the plant can die from an excess of moisture, but the cactus tolerates drought quite well. If you accidentally pour more water than necessary, then wait 5-10 minutes until the plant absorbs the amount of water it needs, and pour out the rest. In cooler seasons, it is recommended to water the plant once every few weeks, depending on how dry the soil is. But in winter, it is better to refrain from watering altogether, since low temperatures in combination with moist soil can cause root rot. During the period of active growth of the plant, it is recommended to feed it with fertilizers with low nitrogen content. Transplanting a cactus into fresh soil annually will have a positive effect on its growth. As far as temperature is concerned, Silver Torch cactus thrives at normal room temperatures (50-60 °F). The cactus can tolerate lower temperatures, but make sure that it does not fall below 20 °F, as in this case you risk harming the plant.


You can easily propagate the plant by cutting off a small branch from the mature plant and rooting it in a separate container. You will know that the reproduction was successful when the root system of the cut branch begins to develop. But keep in mind that such a procedure will inevitably leave an unattractive scar on the cactus near the base of the stem. The plant will take about a week to heal. You can also easily grow the plant from seed, but this method will take much longer.


Pruning the cactus is optional. However, with these procedures, you can speed up the growth of the plant and keep it upright. There are no specific times when pruning should be done, you can do it any time of the year.


Like any other plant, the silver torch cactus can fall prey to pests. The most common cactus pests are spider mites and mealybugs. Getting rid of them is not difficult, ordinary rubbing alcohol can help you with this. Soak cotton wool in alcohol and wipe the cactus stems thoroughly. This will be enough to remove unwanted guests.
