If you're wondering whether cacti should be partially shaded, the answer is yes! While cacti are typically known for being sun-loving plants, they will appreciate some protection from the harsh afternoon sun. This is especially true in hot summer climates. Partial shading will help prevent your cactus from getting sunburned or overheated.
When choosing a spot to place your cactus, look for an area that gets bright sunlight in the morning but is sheltered from the hot afternoon sun. A south-facing window is a good option. You can also create partial shade by draping a sheer curtain over your cactus's pot or placing it beneath a tree or shrub.
Just be sure not to put your cactus in complete darkness, as it needs some light to photosynthesize and grow properly. If you have any questions about caring for your cactus, feel free to ask a professional at your local nursery or garden center.
