B. Cinnamon works well as a rooting agent. Cinnamon powder applied to the stem when planting a cutting will stimulate root growth in most plants. Roll the dampened ends of plant cuttings in cinnamon and it will encourage the growth of additional shoots. At the same time it will keep the cutting disease free while it is developing. I've heard of people mixing Honey with the cinnamon and then rolling the cutting in it - which sounds feasible as the honey has anti-bacterial properties and will also serve as a nutrient for the cutting.

1. Fill your containers with a 50/50 blend of perlite and vermiculite.
Perlite is composed of minerals that have been subjected to high heat which caused it to "plump" up and expand.
Vermiculite retains an amazing amount of water, 200% - 300% by weight. Perlite does not retain nearly enough water, it moves water through transpiration, but does not actually hold or retain any substantial quantity. A 50-50 blend of perlite and vermiculite works well in that it allows for hydration and oxygenation of the developing roots.
2. Take cuttings of 5 - 6 inches each. Remove any flowers or buds. Remove the bottom leaves leaving only two leaves near the top of the cutting.
3. Put the cuttings into the perlite blend, don'tram it in -rather clear a space for it then gently move the blended media back around the butt end of the cutting to keep it anchored in place. It should be buried deep enough into the perlite so that the spots where you removed the lower leaves from is buried - this is where most of your new roots will be developing.
4. Keep the cuttings warm and shaded. Steady Direct sunlight will kill them.
5. Keep them warm, moist and shaded for at least a week.
6. In the second week, you should see new root systems developing. Its at this point that you'll want to gradually reintroduce the cuttings to sunlight - I said gradually , a wee bit at a time.
7. By the third week, your cuttings should be ready for transplant into the garden.
Other edible Plants that can be propagated from cuttings include Rosemary, Mint family plants such as peppermint and spearmint, Currants, Basil, Lemon Verbena, some other nightshade family plants such as peppers and eggplant.
The technique and timing varies slightly from plant to plant. A cutting is generally started from a softwood cutting.
