How to care for Thelocactus macdowellii
Water
Thelocactus macdowellii does best in dry soil and should only be watered sparingly.
Soil
To keep your Thelocactus macdowellii healthy, it's important to use a potting soil that won't retain too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and some organic matter for nutrition is ideal. Adding a few handfuls of perlite to regular cactus soil from the store is an easy way to create this type of soil mix.
Lighting
Thelocactus macdowellii thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Thelocactus macdowellii.
