All About Perennials
A perennial is defined as a plant having a life cycle lasting more than two years. They may be evergreen or deciduous, with the visible parts of the plant dying each winter and growing new plant parts each spring. Perennials can be shrubs and trees as well as tender plants such as geraniums and African violets.
- Dig the hole to a depth that matches the depth of the pot the perennial comes in...and two times as wide in every direction.
- Thoroughly water the plant before removing it from the container.
- If the roots ball is dense and thick, carefully rough it up on the outside with a fork or your hand. This will cause the plant to send out new feeder roots.
- You may want to apply a small amount of slow release coated fertilizer in the bottom of the planting hole before positioning the plant. Do not use granular fertilizer.
- Amend the soil you removed from the hole with organic compost. Mix using 1/4 compost to 3/4 soil. Backfill the planting hole with this mixture. Tamp down firmly. Create a shallow berm, or moat, around the plant to hold water for 4-6 weeks after planting. This will direct the water to the root system. After that, rake the soil smoothly away from the planting hole.
- Mulch with 2-3 inches of organic mulch, keeping it away from the stem or trunk of the plant.
