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.
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.
