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.
Question I have several Thompson's that are leaning and one is on the ground. The roots are in the ground and the top is green. I have several others that are starting to lean in the middle of the trunk. What do I do? What causes this to happen?
Answer Hello Linda,
If the leaning starts at the ground (as if it is not steady, and wants to tip over), than the soil is loose and might want to consider transplanting. This is also caused do to overwatering, which doesn't give the soil a chance to harden as it dries. However, leaning is mostly due to phototropism, meaning the cacti wants to grow toward the direction of sunlight. If they are in a shaded area (or in some point in time), than it is definitely phototropism. Trying to lean the plant back into place is a bit tricky, and it takes time. A LOT of time. And it would look unattractive, as placing an opaque object in the direction of the light is unwanted.
But don't worry. As long as the plant gets atleast 4 hours of sunlight, and is in a bright place, than the plant will be okay.
