Clever Gardening Technique

Soft Wood Cuttings
Propagate favorite roses from soft wood cuttings. Select a stem with a bloom to ensure success. The cutting should be 12 - 18 inches long with several sets of leaves. At the top of the stem, cut just above the leaf to remove the flower; at the bottom of the stem, cut just below the leaf joint. Dip the bottom cut into rooting hormone, then stick the prepared cutting into a pot filled with fresh, damp potting soil. Cover the pot with a plastic bag to retain moisture and place in a warm, bright location away from direct sunlight. Make more than one cutting to ensure success.

The cuttings should begin to root in one to two months. Open the bag and test for root growth by gently pulling on the cutting. You should feel resistance when roots have formed.
