Shade gardening comes with some distinct challenges, including a perceived lack of interesting plants to choose from. Gardening with perennials in the shade is more than just Hostas. But Hostas are amazing, so if that is all you planted, you would be winning!
Let’s get started.
Assess the light. Do you have part sun or full shade? How many hours, truly, do the different areas of your shade garden receive? Part sun is morning light or about 4 hours of sunlight. Dappled light counts more towards full shade. Full shade is no direct sunlight for the majority of the day.
Understand plant tags. Plants labeled part sun/part shade will do best in morning sun or dappled sun. Afternoon sun is often too hot, causing plants to melt and suffer. Part sun to full sun plants will prefer a little more light, so they may do OK in 3 hours but will be happier in 4 or 5. Full sun plants want at least 6 hours to perform their best. As with all rules there are exceptions, so just ask our talented Perennial Team at Tonkadale.
Assess the soil. Dry or wet? Many shade plants want rich soil that is consistently moist. There are a few shade plants that can handle dry soil, though. Irrigation, such as a drip line, may be necessary for some plants to survive and thrive if the area is not naturally damp enough. The good news is, shady areas are by nature more moist and require less watering The exception could be sandy soil, a sloping landscape, or a short blast of afternoon sun.
Discover the roots. Trees make garden areas shady. When preparing the soil be sure to consider tree roots. There are some that are simply too large to plant certain perennials by, and in that situation there are a handful of ground covers that will work.
Design tips. Work with your existing landscape. Remember, if you have a shade garden, you don’t have a barren landscape. You have wonderful, mature trees, and that’s a bonus. Trees are the backdrop and a major feature of you garden. Contrast foliage color, shape, and texture. Add a curved path that draws you through the garden. Add a bench or water feature that gives your body and eye a place to rest. The stillness of a shade garden is really one of its best features. Connect the edges of the shade garden to its sunny border by planting part sun plants that offer more flower power and color.
