9 Drought-Tolerant Shrubs That Thrive in Dry Shade Under Trees

Dry shade under trees is one of the most challenging areas to plant in any garden. Between thirsty tree roots, low light, and poor soil, it’s no surprise that many borders beneath trees end up sparse or bare. But it doesn’t have to be that way.

With the right shrubs, you can bring structure, colour, and year-round interest to these tricky spots — without constant watering or fuss. Whether you’re working under deciduous trees, mature evergreens, or a mix of both, the key is choosing tough, shade-tolerant plants that can cope with competition and low moisture.

In this article, I’m sharing 9 drought-tolerant shrubs that I’ve found to be reliable in dry, shady areas — including my own garden in Formby. Wherever possible, I’ve included links to trusted UK suppliers (or my own shop), so you can source these plants easily and start transforming that difficult border.

Why Dry Shade Is So Difficult (and What to Look for in a Shrub)

If you’ve ever tried to plant under a tree and watched everything struggle or die, you’re not alone. Dry shade is one of the toughest conditions in gardening — and it happens when trees create dense root networks that suck up moisture, block sunlight, and leave very little for anything else to thrive.

To make matters harder, many trees also create acidic or compacted soil, especially if the area hasn’t been mulched or amended regularly. It’s not impossible to plant in these conditions — but you need the right approach.

That’s where drought-tolerant shrubs come in. Unlike delicate perennials or thirsty groundcovers, these shrubs are tough enough to cope with root competition and periods of dryness. Many are evergreen, giving you structure and greenery year-round — even when the rest of the garden is dormant.

When choosing shrubs for dry shade, look for plants that are:

  • Happy in low light or dappled shade

  • Able to tolerate low water availability

  • Ideally low-maintenance and slow-growing

  • Suited to UK conditions (not just warm-climate lists!)

Up next, you’ll find a selection of shrubs that meet these criteria — and that I’ve found to be genuinely reliable in tricky spots under trees.

Planting Tips for Dry Shade Success

Even the toughest shrubs benefit from a bit of help when planting in dry shade. Tree roots compete aggressively for moisture and nutrients, so giving your new plants a good start makes all the difference.

Here are some tips I use when planting under trees:

🌱 1. Soak the Planting Hole Before Planting

Tree roots often leave the surrounding soil dry even after rain. Fill the hole with water and let it drain before planting to help new roots settle in.

🌿 2. Add Organic Matter to Improve Soil

Mix compost or well-rotted manure into the planting hole to hold moisture and boost nutrients.
👉 Try Growmoor Multi-Purpose Compost

🪵 3. Mulch After Planting — And Keep Topping It Up

A thick mulch layer (5–8cm) helps conserve moisture and suppress weeds. Reapply each year in early spring or autumn.

🚿 4. Water Well During the First Growing Season

Even drought-tolerant shrubs need consistent moisture until their roots establish — especially in spring and early summer.

🌤️ 5. Don’t Plant Too Close to the Tree Trunk

Give plants at least 50–60cm from the base of the tree where light and moisture are more available.

A little prep at the start means less maintenance later — and a much higher success rate under those demanding tree canopies.

Transform That Bare Patch Under the Trees

Dry shade doesn’t have to be a dead zone. With the right shrubs, even the toughest spots under trees can become some of the most beautiful and rewarding areas in your garden.

The shrubs listed above have been chosen not just for their resilience, but for their year-round interest, low maintenance, and ability to bring structure and colour where little else grows.
