Making a Rosemary Topiary

In the first stage, you want the plant to grow straight up to the desired height, which can bee anywhere from 12" to 36". Place a stake beside the plant, and tie the plant along the stake for support. Allow the tip shoot of the plant to develop, by cutting off any wild side shoots that start to grow. Allow leaves to stay on the trunk. Check the ties often so they don't girdle or injure the growing stem. Check also for mealybugs that like to hide around the ties. Turn your plant frequently so each side receives adequate light and it grows evenly. Feed your topiary every four or five waterings during active growth with a 15-30-15 liquid fertilizer for houseplants. (If you buy a an unpruned rosemary from us, the above steps have already already been done.)
The next stage is forming the top of the plant to the desired shape. Before you pinch the growing shoot tip for the first time, think of the finished look you want your plant to have. Consider leaf size and rate of growth. Where do you plan to display your topiary and what kind of container will it live in? You may want to allow the plant to grow even taller. Do you want a one-ball, two-ball or three-ball standard? Perhaps you want a pyramid or a Christmas Tree-shaped tope? When you have determined these, pinch out the tip of the trunk, and strip the leaves off of the main trunk where you are sure you don't want them. Allow appropriate, correctly spaced branches to develop. The trunk will elongate a bit as it matures and thickens. Keep turning your topiary in the light so that it grows evenly.

Now comes the real art of topiary. You have to keep in mind the shape you want the plant to take and train the plant through careful tip pinching. Pinch tips about every 2 inches. Pinch or cut at nodes so that new shoots will grow in the direction you want. You also want to encourage width and branching at the base of the "head." Top growth will naturally develop faster, so keep upward growing shoots trimmed down. As you become aware of growth habits and observe the results of careful pruning, you will better be able to train the topiary to the finished shape you want. During indoor growing periods you will need to be conscientious about providing rosemary with the conditions it needs - most importantly adequate ambient humidity and reasonable temps. I have seen many reasonably experienced gardeners loose rosemarys in February to powdery mildew - directly the result of not taking proper care of the plants.
Many herbs can be used for topiary, in addition to rosemary. French lavender, scented geraniums, bay laurel and lemon eucalyptus, for example. The herbs you choose will depend on the topiary shapes you want to create, so be creative and have fun!
