Plants to Shade: Clematis Roots
- Shaded roots stay cool and well hydrated. Site the clematis carefully and plant deeply. Nearby trees and shrubs can provide shade, as can more closely planted, shallower rooted annuals and perennials. The shade keeps the roots, which can go down as much as 4 feet, cool and moist, allowing for the development of a strong root system. Competition for moisture and nutrients will be kept in check if you site companion plants at an appropriate distance.
- Plant clematis with the root ball 3 to 4 inches below ground level. Dig a hole deep enough, and twice to three times as wide as the nursery pot. Settle the plant in the hole. Mix the removed garden soil with compost, half and half, and fill the hole this mix. Water well, and allow soil to settle. Add more soil to bring to ground level, if necessary. Provide a 2-inch layer of composted mulch.
- Plant shallow-rooted annuals, such as pansies, petunias or sweet alyssum, to within 1 foot of the base of the clematis. These will not interfere with deeper clematis roots if sufficient water is provided. Try perennials like iberis sempervirens, angel hair artemesia, phlox subulata, or dianthus 2 feet from the clematis. A miniature or larger rose bush, butterfly bush, or another favorite shrub or small tree can be planted 3 feet or more away from the clematis. You may plant the clematis at the drip line of a larger tree.

Avoid invasive ground covers such as vinca or grasses. Deeply rooted perennials, such as gaura, and large shrubs, or trees planted too closely, compete for water and nutrients, and the clematis will struggle. Consult your local nursery for information regarding plants in your zone to choose or avoid. Local conditions vary, so monitor newly planted clematis and their companions throughout the growing season, and provide sufficient moisture.
