1. Sunlight & Temperature

Belonging to the Cacti family, Domino Cactus prefers full sun and hot days to boost its growth.

The ideal condition for Domino is at least 6 hours of full bright sun and partial shade during extreme afternoons, with temperatures ranging from 70ºF to 80ºF.

However, these Cactus plants are intolerant to cold drafts below 50ºF, as they will lose their vibrancy and start having soft tissue.

So you can keep them outdoors only during hot summer days and bring them indoors before cold drafts hit the plant.

Be sure to prevent scorching lights from falling on the Cactus if there are water drops, as the rays of light initiate plant burning in the presence of water.

If you plan to grow the plants indoors in the winter or without enough light, you can install grow lights and put heating mats under the pot to maintain the warmth.

The best location to keep Domino Cactus indoors is a window facing the South and a patio with enough light outdoors.

2. Watering & Humidity

Domino Cactus is drought tolerant but check the humidity around the plant before watering. 

The optimum humidity preferred is about 40%, with a continuous flow of air and water every two weeks, depending on the moisture in the soil.

And remember to let the soil dry before the next watering to prevent overwatering that may lead to root rot, giving a mushy look and rotten smell from the plant side.

But do not wait too long until the Cacti suffer from underwatering, leading to wrinkling and shriveling up of the top.

So it is best to give 0.9 cups of water every nine days during summer and mist the plant every 12 days in the dormant period.

Meanwhile, you can install a dehumidifier beside the Cacti to maintain the dry air.

And move the plants from moist places, including the kitchen or bathroom, to a drier zone to prevent disease infestation, mold, and fungus formation.

3. Soil & Fertilization

Domino Cactus flourishes more in well-draining soil with low water retention quality and rich manure content with a pH of 5-7.

You can buy the soil from the online store for Cactus or succulent mix or make your DIY potting soil.

Take sand, silt, and clay in a ratio of 2:2:1 or peat and perlite in a 1:1 ratio and enrich them with pumice, mulch, or organic manure to boost drainage and aeration.

Moreover, you can apply Cacti or balanced fertilizer directly into the roots monthly during spring and summer.

But it is better to offer the natural organic mix as it is not a heavy feeder, mainly in winter, as they are dormant.

Excess fertilization suffocates your Cactus and causes the wooly green foliage to turn yellow and have brown spots.

Also, keep the soil dry rather than soggy to prevent pest infestation. 

4. Potting and Repotting

Domino Cactus is not fussy regarding the container as long as it matches the plant size and has enough drainage holes.

The bigger pot leads to overwatering and soggy soil, consuming time to dry out and ultimately inviting rot.

So choose a terracotta pot 5 inches wide and 6 inches deep. And after 2-3 years, repotting becomes an option, given the slow growth of Cactus.

However, you might need to repot them once they have pups or are suffering from soil problems.

So repot them indoors during summer into an inch bigger pot, but check for dryness in the soil before repotting to prevent shock to the Cacti.

Pull the Cactus wearing garden gloves and tuck off the excess soil in the roots, fill a pot with the cactus mix, add some pebbles at the base of the container, and plant the Cacti by spreading its roots.

Lastly, cover the top with the mix, let it stay dry for at least a week, and offer light water. 

5. Occasional Pruning

Given the unique globular foliar structure, Domino Cactus demands less or no pruning.

You need to prune Domino Cactus if it has a decay or diseased spot in the stem, usually caused by mold, fungus or pest.

The most common pest attacking Domino Cactus are scales or thrips that tend to hide beneath the wooly areoles.

So, look over symptoms like plants appearing weak, thin, and white substance over the foliage for the presence of pests.

You can control the infestation by trimming the damaged parts off and spraying rubbing alcohol, insecticidal soap or neem oil over the affected area.

Moreover, the Cacti can also be a victim of fungal diseases like root rot and black spots over the foliage, where pruning comes into action the most.

But firstly, you have to isolate the Cacti from other plants and cut off the affected part using sterilized garden pruners or scissors.

Domino Cactus: All About Growth Rate

All members of the Cactus family are famous for their slow growth, same for Domino Cactus.

Moreover, the Domino Cactus spherical foliage has an areole bearing one central and 3-7 radial spines that are soft and not prickly and rises to pups and offsets once they grow old.

Toxicity of Domino Cactus

Feel secure about bringing Domino Cactus home as they are not toxic to humans or pets like cats and dogs.

However, it is better to keep them away from the reach of children and companion pets as they might chew up on them and create discomfort in the stomach.

Domino Cactus takes about 12 months to reach maturity from the seeds.

2. Propagation via Offsets

Offsets are small pups that you can find easily at the base of the mother Domino Cactus, near the roots.

  • Start the process in early spring to anytime until late summer.
  • Cut off the offsets gently using a sterile knife, or you can even twist it off using your finger without hurting the mother plant.
