Heather grows wild along French fields, it dots the English moors, and it also thrives in the tropical climate of Mexico. Known formally as Cuphea hyssopifolia, the variety most popular in the U.S. is known informally as Mexican heather or false heather. This hardy, low-mounding plant with tiny flowers only appears delicate, and it is ideal for potting and placing on a patio, porch or as a low border around a pool. Heather is an annual that will die back within about 12 months requiring you to purchase new plants every year.
Prepare a pot that is larger than the current pot by at least 1 inch. The roots need room to grow, and the plant will thrive if it has a larger pot in which it can expand.
Add about a 1/2-inch layer of pea gravel in the bottom of the pot. If you have a saucer for your pot, place the pot inside the saucer before filling it with the gravel.
Put on your gardening gloves and scoop about 1 inch of potting soil on top of the pea gravel.
Snip roots if they grew in a circular pattern in the old pot and loosen the root-ball with your fingers.
Center the heather plant into the new pot and surround the plant and roots with potting soil, filling the pot until the soil reaches within 1 inch of the pot's rim.
Pat down the soil gently but don't pack it. Make sure the plant has enough soil supporting it to remain upright.
Water the plant well.
Make sure you are using high-quality, well-draining soil. Fertilise your plant every two to three weeks.
