HORTICULTURE

Detailed explanation-1: -It is important that this bottom remains free of bacteria. The bacteria can develop slime around the stem, clogging the vessels. The thorns are best left on the stem if possible; when you remove them there are wounds where bacteria can penetrate.

Detailed explanation-2: -Remove individual thorns with a paring knife or nail clippers. Cut each thorn at the stem, or just cut off the sharp part at the end of the thorn. To remove multiple thorns in a row, run your covered hand slowly down the length of the stem, pressing firmly. This will remove both thorns and leaves along the stem.

Detailed explanation-3: -Plants have thorns to deter herbivores (animals that eat plants) from eating the leaves that the plant put so much energy into making. This type of defense is known as physical defense, because the plant physically defends against herbivores by poking them.
