The Secret Garden Under Trees!

> Back

Trees make gardens look beautiful and give them shape, like big umbrellas with leafy tops! But did you know that some plants and flowers like to grow right under trees? This special place is called the understory.

Some small trees, like holly and dogwood, are perfect for living in the understory. They're like the helpful little brothers and sisters of big trees!

The understory is a cool, shady home for tiny bugs and animals. Because the big tree's leaves block a lot of sunshine, it stays dark and damp down there.

As trees grow bigger, their roots spread out to drink up water from the soil, and their branches make even more shade. This can make it hard for other plants to grow underneath.

But don’t worry! If you want to plant flowers under a tree, there are smart ways to help them grow strong and healthy. Just follow a few simple tips, and your garden will be full of life, even in the shade!

Choose The Right Plants

When planting under a tree, it’s important to choose the right kind of plants, ones that like the shade and don’t need too much water.

Plants that grow in forests are a great choice because they’re used to living under big trees. Some good ones to try are ferns and foxgloves, which occur naturally in our woods, or hostas and hellebores, which are garden plants that love shade. (They have fun names, don’t they?)

It’s best to pick small, young plants. They’re easier to plant and won’t bother the tree’s roots. Plus, baby plants are better at getting used to new homes!

Be Kind to Tree Roots

Trees have lots of roots under the ground, kind of like hidden arms! These roots help them drink water and stay strong. So when planting, try not to dig too much.

Instead of big holes, just gently loosen the top layer of soil. Look for little spaces between the big roots to tuck in your plants - never cut through thick roots!

Add a Cosy Blanket (Mulch!)

After planting, you can give your garden a soft, protective blanket called mulch. It’s made from things like bark or old leaves.

Spread a layer about 2–3 inches thick. Mulch helps the soil stay moist and gives food to plants as it breaks down. Just remember: keep mulch a little bit away from the tree trunk, like giving it breathing space.

Don’t Forget to Water

New plants need lots of care. Water them regularly, especially during their first growing season.

Since trees drink a lot of water too, make sure your plants get enough. Check the soil with your finger; if it feels dry, it’s time to give them a good drink!

Keep It Simple And Natural

Don’t use too many kinds of plants - just a few that look nice together.

Try planting the same kind of plant in little groups. That’s how they grow in the forest, and it helps them share space better too!

Fun Design Ideas

Layer your plants: Start with tiny ones like bulbs, then add small flowers, and finish with taller ferns or bushes.
Group them together: Plant in clumps, like nature does.
Mix up bloom times: Some flowers bloom early (like snowdrops), some bloom later (like foxgloves). That way, there’s always something pretty to see!

Keep an Eye on Your Garden

Trees grow and change, and the spot under them can change too.

If your plants don’t look happy, try moving them or picking new ones that fit the new amount of light or water.

Your garden will always be growing and changing, just like you!
