Question
I have a cactus that originally was a one-inch tall plant that was given to me about 20 years ago.  It has grown over the years to a tall skinny 12 feet and I just cut off the top 4-5 feet because I have run out of ceiling height.  What is the proper way to prepare it for planting?  I have heard conflicting things.  Can I stick it immediately into soil or does it need to "Harden" (whatever that means) and for how long?  How deep should I plant it? Thank you.  Please respond to me via my email address. Chris

Hello Chris,

Unfortunately, your email address was not in your message. Anyway, your plant does need to "harden" or heal as I call it. After the cut portion of the plant heals (becomes hard to the touch), in about 2 or 3 weeks minimum, it can then be planted. If your cutting is 4 to 5 feet tall, then you will want to plant it about 5 or 6 inches into the soil. Make sure to stake it so it doesn't fall over.

Water thoroughly with a rooting hormone added (Superthrive is the best), then let the soil dry out before watering again. Do not over water or the plant will rot. Also, make sure to use a "cactus mix" type soil. You will know when it has rooted, because the plant will start swelling up and possibly start putting on new growth. I hope this helps. Good Luck!

Sincerely,

Greg
