Like most passionate gardeners, I am always looking for new plants. Whether I'm visiting a friend's garden, hiking a nature trail or just driving down the road, when I spot an interesting plant, I must check it out. This usually leads to wondering if I could grow it at home. That's why I always have pruners, paper towels, plastic baggies and a bottle of water handy to take a cutting.
In propagation from cuttings, a gardener cuts off a piece of an annual, perennial, tree or shrub and grows an entirely new plant from that part. There are three types of cuttings: stem, leaf and root. Stem cuttings form roots and leaves; leaf cuttings form roots and stems; root cuttings form stems and leaves.
The concept is simple. Placing the growth tissue within a leaf or stem in direct contact with soil will initiate the formation of roots and spur growth of the other missing part. Buried bits of fleshy roots without shoots will respond by forming new stems and leaves. All three methods produce the same result: an exact clone of the plant from which the cutting was taken.
TAKING STEM & LEAF CUTTINGS
The best stem cuttings come from the younger stems of woody plants or any stem from an herbaceous plant. Stem cuttings of coleus, dracaena and geranium are practically guaranteed to work.
Leaf cuttings can include or exclude the petiole (the stalk connecting leaf to stem). The fleshier the leaf, the better; succulents like sedum (Sedum), jade (Crassula) or snake plant (Dracaena trifasciata, formerly Sansevieria trifasciata) are particularly easy because their leaves store moisture and have lots of growth tissue.
Before you take a cutting, sanitize your cutting tool with rubbing alcohol to prevent the transfer of pathogens from the knife or pruners to the plant, or from plant to plant when taking multiple cuttings.

The best crops to plant throughout summer, plus how to time them right. Once a crop like spring turnips or snap peas has finished, I tidy up the bed, amend the soil with a thin layer of compost and replant. Depending on the new crop, I may be sowing seeds or transplanting seedlings.
