Do all plants grow roots when separated from parent?
Dear respected person,

I am not a professional botanist, but I adore gardening, and would like to help you as much as I can from my humble garden experience.

As far as I have experienced, not all plants have stems which root when put in the ground. For instance, I have a plant called Bouganville Tom Thumb (I apologise for any spelling error). I once decided to clone this Tom Thumb variety by cutting its stem off and then burying its base in potting soil. I even tried rooting hormone powder (from a gardening store) but it did not root, even after a whole month.

On the other hand, I had a plant called Petunia whose stem I cut off on purpose to maintain the plant's shape and threw the stem into the soil. The stem shriveled, and I thought it died and left it there. However, to my surprise, I found the stem all fresh after 2 weeks only to find that it had rooted into the soil from side of its stem. Another plant called Jade Plant can be cloned by putting its leaf in soil.

I think it really depends on the type of plant whether its stems will root or not and how long the stem will retain its rooting potential after being cut.

If possible, you can try the following. Put the cut stem in a small plastic pot (they are very cheap) with soil and see if it roots (leaves will begin growing). If it does, transfer it into a larger pot later once it has grown. Wait for it to grow big enough to spread its roots thoughout the pot, then shift it into a big pot.

I believe if a plant roots, then all stems of that plant will root. Plus, congratulations on your first plant.
