About Joan Expertise Prickly pear, saguaro, barrel cactus, house cacti... You name it! I will answer all your questions regarding cacti such as winter care, propagation, watering, and indoor care. I will also answer questions on edible cacti (for humans or pets) and identification. In addition, I may answer questions on other succulent plants, such as the agave.
Experience Due to the arid climate here in Nevada, I grew up planting cacti and shrubs to design my landscapes. As years went on, I learned the different ways on taking care of these amazing cacti, especially how to propagate them.
Education/Credentials During the past few years, I have tried out many methods in growing cacti, especially when it comes to propagation. I learned the dangers of over-watering, and have researched that people often make common mistakes. That is why I joined to be part of AllExperts.
I have a potted Austrocylindropuntia Subulata. "He" was once small and without spines/needles. Two years ago, I transferred him to a larger pot where he has grown to giant proportions. But he did not grow spines. For the past year, he has been under the care of a friend who has a garden while I have been away. He has just been returned to me and I see that he has grown many sharp spines. I would prefer him to be without spines- both aesthetically and for human care purposes. I've tried researching whether or not it is safe or unhealthy to remove the spines of this cactus species and what methods there are for doing so. I've seen various comments ranging from "Don't remove the spines" to "It's fine to remove them, and the best way is by burning them off with a lighter (as opposed to cutting them off)."
I'd really appreciate your insight.
Thanks a lot,
Nili
Answer Hello Nili,
It is important for you to know that it is best to leave the plants at its natural way of life. But if you consider to remove them, remove them with the consideration of leaving a small part of the spine left on the cactus. Depending on the species, the left over part of the spine should fall off naturally. Pulling the spines might not effect the plant, and the spots would heal. But I strongly suggest leaving the spines or as I instructed above.
