Water sparingly in winter. Pinch tips to encourage bushier growth. Fertilize every three months or so while the trees are actively growing. Or, if you have a balcony, you can place them outdoors. Pit-grown avocados that are protected from cold may flower in about seven years.

Several nurseries carry this fragrant shrub that produces clusters of tiny, surprisingly fragrant white blooms in winter and spring. They do like fertile soil and are at their best when it's slightly acidic. The foliage you mailed was severely damaged, but it appears the weed that caused such an allergic reaction is a member of the Labiatae, or mint, family. One is ground ivy, a creeping perennial with four-sided hairy stems and rounded, scalloped small leaves. The leaves appear in pairs on opposite sides of the prostrate stems, and rooting occurs easily at the nodes.
