Thimble Cactus

Water moderately and only when the soil is dry. If you have an immature Thimble Cactus, water it more often but allow the soil to dry between waterings. The adult cactus have adapted to arid climates and can survive for long periods without water. When watering, ensure that the water reaches downward through the stem and into the roots. Too much watering causes root rot, so make sure to let the soil to dry in between waterings.

Thimble Cactus need plenty of bright light, preferably direct sunlight, to grow and develop healthy. It is also okay to have lighter light during the day but they should not be outside in the path of direct light for too long in the summer, especially when temperatures reach their highest peak. If the cactus is kept inside, it should be placed near a window that receives at least four hours of direct sunlight each day. It's also important to rotate the cactus regularly so the light exposure is balanced on all sides.

Thimble Cactus fare best in temperatures between 50 to 80°F (10 to 27°C). This cactus can still tolerate temperatures below 30℉ (-1℃) but should be protected from extreme cold. If you are growing them indoors, do not place them near a drafty window and keep them away from any appliance that has heat.

Thimble Cactus prefer dry, arid conditions. High humidity can cause them to rot so if your plant is grown indoors you should monitor and keep humidity levels at around 40-50%. This can be done by making sure the air is constantly moving around the plant, and avoid overwatering.

Thimble Cacti thrive in a fast-draining soil that is slightly acidic. Cactus mix soil works well as it provides proper nutrition and moisture retention. A good soil mix includes equal parts perlite, peat, and sand or coarse gravel. You should also engrain organic matter like manure or compost for an added boost.

It is not necessary to fertilize Thimble Cacti frequently. Fertilizing once during the spring season will suffice. Use a balanced formulation, like a 10-10-10 fertilizer, diluted to half the strength. Too much fertilizer will encourage leaf growth, which is not what you want for cacti, as it will diminish the stem’s growth. Feed them twice a year, every six months, with a diluted fertilizer solution and you’ll see the difference!

Thimble Cactus are prone to certain pests including mealybugs, aphids, and scales. Mealybugs appear as small white fluffy cotton-like patches, while aphids appear as small pearl-like pieces. To get rid of mealybugs and aphids, you should dip the plant in a soapy water solution or spray it with an insecticide. Scales appear as small brown & black spots and can be gotten rid of by dabbing them with a cotton swab dipped in alcohol. Other effective methods of control include the use of horticultural oil and insecticidal soap.

Thimble Cactus require repotting only once a year, during the spring season. You should wait until the soil has fully dried before you move it to the new container, and you should ensure that the new pot has adequate drainage. Make sure the soil is well-draining cactus mix and repot the cactus to its new home. You can use stones and gravel at the bottom of the pot to ensure proper drainage.

You can prune Thimble Cacti if needed so that they maintain their original form. The pruning should be done only after the flowering season to avoid any damage, and you should use a sterilized pair of scissors for the process. Prune the unhealthy or dying stems and remove any dead leaves or rotted stems as this may encourage new growth.

Mulching these cacti is not needed. Mulch can provide additional nutrients but the Thimble Cactus are adapted to survive in low-nutrient soil.

Thimble Cactus can be propagated easily through either seeds or stem cuttings. For stem cuttings, let the wound dry for a day or two, then dip the cuttings in rooting hormones and place them in a pot with well-draining soil. Additionally, the seeds can be started in sterile growing medium and then transferred to a pot of cactus soil when they've sprouted sufficiently.

Thimble Cacti do not require any support as they are naturally self- branching. These cacti can be wired or staked if they become too top heavy.

Thimble Cacti should be kept in a cool area and should receive very little or no water during the winter season to induce dormancy. Going into dormancy will ultimately help the cactus to grow well in the coming spring season.

The Thimble Cactus has no known toxicity, and is considered safe for human and animal contact.
