Black Jade Plant Care


Black jades--also known as miniature roses--are deciduous rose bushes that only reach a height and width of about 1 ½ to 2 feet. Their flowers are deep red which can appear black from a distance and bloom from spring until the first frost. Black jades prefer full sun and well draining soil, and are grown in United Sates Department of Agriculture zones 5 to 9.

Step 1

Keep the area well weeded. Also, any sucker plants that grow should be removed. Get up all the roots so they don't grow right back.

Step 2

Mulch under the entire canopy of your black jade plants. Use about 2 to 3 inches of organic mulch such as bark, pine needles or wood chips. Mulch will help the plants retain water and stay cool during the warm months, as well as help the roots stay warm during the cold months. It also helps keep weeds under control. Replace the mulch as it decomposes.

Step 3

Water your black jade plants often during the growing season, but do not let them sit in water. Generally, about an inch of water every day during the hot summer months, or every couple days during warm or cool weather, will suffice. Water in the mornings for best water retention.

Step 4

Pinch off flowers after they bloom. This practice will encourage more blooms and will result in a thicker, fuller rose bush.

Step 5

Remove diseased or dead branches and leaves. In addition, remove fallen limbs and leaves from under the bushes often. This practice will help prevent disease from spreading to your entire bush.

Step 6

Prune in late winter or early spring. Remove dead branches and weak limbs. This is a good time to shape your plant as well, if desired.

Step 7

Treat pests and diseases as needed, such as blackspot and aphids. Take a sample of an affected leaf or stem to your local nursery for proper diagnosis and get the right treatment, often an insecticidal soap.
