We often think of cacti as the ultimate “set it and forget it” plants, but even these prickly little guys need a little TLC to really thrive. If you want your desert beauties to live a long, happy life and maybe even show off some blooms, there are a few key things you need to get right. Here’s the lowdown on keeping your cacti in tip-top shape:
Factor #1: Finding the Perfect Spot
Your cactus is going to be happiest when its light and temperature mimic its natural home. For desert cacti, that means a sunny to full-sun spot from mid-March through September. They love it warm, ideally between 75°F and 95°F.
Forest or “leaf” cacti (like Christmas cacti), on the other hand, prefer partial shade from spring through late summer. They also appreciate a bit more humidity—around 60% is the sweet spot. Pro tip: both types love spending their summer vacation (May through August) outside on a sunny balcony or patio!
Factor #2: The Winter Nap
When the weather turns chilly, almost all cacti need a cool, bright place to settle in for their winter dormancy. This rest period is super important because it’s when the plant gears up for the next growing season and starts developing those beautiful flowers. Aim for temperatures between 40°F and 55°F. (Check out the watering and feeding tips below for what to do during this “nap” time).
Factor #3: Watering and Feeding Like a Pro
The golden rule for cactus care is “soak and dry” during the growing season, and “keep it dry” during the winter. To get your watering and fertilizing routine just right, follow this schedule:
- March through August: Let the soil dry out completely, then give it a really good soak. Just remember: the bigger the cactus, the longer you can go between waterings.
- Every other watering: Mix in some liquid cactus fertilizer to give them a nutrient boost.
- Starting in September: Start cutting back on water and stop fertilizing altogether.
- November through February: Let the soil stay mostly dry while the plant is in its winter quarters.
While those majestic desert cacti can usually go from November to February on just one last deep soak, leaf cacti are a bit different. You’ll want to give them a tiny bit of water every now and then during the winter so their root balls don’t completely bone-dry.
