Plants for Dry Shade Areas
We know that it can be challenging to find plants that thrive in dry, shady areas of your garden and landscape.
What does dry shade mean? Dry shade means a garden without direct sunlight, and with light that rarely reaches the ground. This includes areas in your garden that are located under eaves, covered porches, balconies, or even under the canopies of large evergreens or established California native oak trees.
Challenges Posed By California Native Oak Trees
California native oak trees are very sensitive to over-watering. They usually don't require irrigation—even during dry California months. In addition, native oaks should not be watered within their driplines, and sprinklers that throw water against the oak's trunks should be avoided.
If you have soil that is bone dry, it's primarily due to the limited amount of rainfall that is able to penetrate the dense mass of the tree's canopy. Plus, the tree's thirsty and extensive system of feeder roots soak up all available water.
Some Ways You Can Alleviate These Pre-Existing Conditions:
- Most trees can be limbed up a bit or the canopy can be selectively thinned to let in more light.
- Conifers can handle the careful pruning of smaller branches (less than 2-inches in width).
- If your soil is dry, you can always provide additional water.
- Never remove more than a fifth of the foliage of any tree during one calendar year.
- The thinning of branches on large trees is a job best left to an ISA certified arborist.
Plants That Thrive In A Dry Shade Garden
The plants featured below were selected based on their low water requirements (once established). Following are some additional guidelines that will encourage their successful growth:
- Water - All young plants need irrigation to get established. This could take one or more growing seasons, depending on the plant. A drip irrigation system is easy to install and adjust the water output of, as the plant's root system matures.
- Soil - Hard, dry soil may need to be amended to let water and air pass through to the plant's roots. Soil can be amended with SummerWinds Planting Mix or other types of organic matter. Speak with one of our Trusted Garden Advisors for advice about your specific landscape challenges.
