As a gardening and landscaping expert, I have had personal experience with growing fishbone cacti as houseplants. When it comes to sunlight, it is important to note that fishbone cacti do not thrive in full sun. In fact, direct sunlight can be quite detrimental to their health.
Fishbone cacti are native to the shady understory of tropical rainforests, where they receive filtered light through the dense canopy. Therefore, exposing them to intense sunlight can lead to leaf damage and discoloration. The leaves may bleach out and become pale in color if they receive too much direct sunlight.
To ensure the optimal growth and health of your fishbone cactus, it is essential to choose a location with semi-bright indirect light. This means finding a spot where the cactus will receive some sunlight, but not the full intensity of direct rays. Ideally, a few hours of morning or late afternoon/evening sunlight would be sufficient.
If you have a window that receives direct sunlight for most of the day, it would be wise to place the fishbone cactus a few feet away from the window or use sheer curtains to filter the light. This will help protect the cactus from the harsh effects of full sun exposure.
In my own experience, I have found that placing my fishbone cacti on a north or east-facing windowsill works well. These windows tend to provide softer, indirect light that is more suitable for the cacti’s needs. Additionally, I have also successfully grown fishbone cacti under fluorescent lights indoors, which can mimic the filtered light conditions they prefer.
To summarize, fishbone cacti do not like full sun and should be kept away from direct sunlight. Opt for a location with semi-bright indirect light, such as a north or east-facing window, or use sheer curtains to filter the sunlight. By providing the right lighting conditions, you can ensure that your fishbone cactus thrives and maintains its vibrant, healthy appearance.
