Will Hostas Grow Under Pine Trees

  • by

The most artistic way to use any open space in your garden under the pine trees is to landscape with flowers, ferns, and grass. Finding plants that do well under pine trees is a little more difficult because they need to thrive in less sunlight and with the acidity of the soil in that area.

You might be dissatisfied with the lack of coverage and the slow growth of grass if you ever try to grow it under a pine tree. Can you plant Hostas under pine trees, is often asked. You can grow a Hosta successfully next to a tree or in a location with lots of shade.

However, not all species will get along because the type of tree your perennial is growing under can influence its health and growth. In our guide, you can learn more about Hostas around tree and what you need to do for tree and plant care. (Learn How To Get Rid Of Ants On Patio)

Can You Grow Hostas In The Shade?

Depending on climate and soil conditions, hostas can tolerate partial and even full shade. As a result, Hostas make an excellent ground cover when planted beneath a tree.

  • Also, Hostas don’t like hot weather or direct sun. In full sun, it may burn or die.
  • This plant’s soil is essential. If your garden has clay or dense ground, your Hosta may suffer.
  • You want to ensure your plant has good drainage since it won’t get much sun. This is important because shaded plants can quickly die.

When growing Hostas under pine trees, it pays to give special attention to how often you water Hostas and how you do this. As long as the soil has been prepared in the early spring, hostas should thrive in the shaded area near the pine tree’s roots.

Coming up to the growing season, add organic matter before planting, mulch is applied, and soil moisture levels are kept, so only water Hostas as needed. Suppose there is a dense network of pine tree roots from several pines or other surrounding trees.

In that case, growing the larger Hosta varieties, such as Hosta ‘Sagae’ may be challenging, which can grow to 70 inches across, and you will have to plant smaller varieties.

Why water using a drip line for Hostas under the Pine Tree?

The only challenge to growing Hostas under pine trees is the dryness of the soil, so leave a soaker hose or drip line to water the plants during the summer. To grow Hostas under pine tree, it is essential to take care of the watering.

Advantages of Mulch for Hostas under Pine Trees:

Mulch aids in enhancing soil structure, holds onto water, and lessens the likelihood of weed growth. In addition, it makes the Hosta more beautiful. Although you can add mulch at any time of the year, it is recommended that you do so in the spring because that is when Hostas grow.

Mulch will also help Hosta retain moisture during the drier summer months of the growing season if applied in the spring season. (Read Can Chickens Have Corn On The Cob)

Problems For Hostas Under Pine Trees and Solutions

What makes growing Hostas under these trees difficult? Here are the challenges pine trees cause for growing Hostas.

Acidic Soil

It’s untrue that pine needles create acidic soil or if you add them to a bed can lower the soil’s pH. The Ponderosa Pine (Pinus ponderosa) tolerates alkaline and saline soils but prefers a pH of 6.0 to 8.0, which is neutral.

Pine trees need well-drained soil like Hostas. However, Hostas and pine trees can’t handle flooding or poorly-drained soil.

Shade

Although not all pine trees can tolerate shade, they offer the shade that Hostas need. Your Hosta plants should receive 3 to 4 hours of direct sunlight each day, ideally in the morning or evening.

Root Structure

Finding space in the shallow root system is problematic when planting Hostas with Pinus roots. Growing the larger Hosta varieties may be challenging if there is a dense network of roots from many pines or nearby trees; here, you will need to plant smaller Hosta varieties.

To accommodate room for additional plants, you might consider strategically chopping some tree roots. However, this isn’t recommended. You can pick plants with bare roots and dig a hole about 12 inches away from the trunk is the most excellent option. The hole needs to be large enough for the root ball.

You’ll be able to get a few Hostas planted this way, and your Hosta roots won’t be affected too much by the tree, as these will be deeper underground.

water and nutrition

Water and Nutrition

The more the roots there are in the planting area, the Hostas and pines have to compete with one another more for moisture and nutrients. Although most Hosta species are resilient and hardy, you might need to ensure your soil before planting Hostas to give them the best chance of establishing roots and flourishing.

By incorporating compost or peat moss into your soil rather than just the hole you dig for your Hosta root ball, you can retain moisture that is enough for both. Two weeks before you plant Hostas, cover the area you intend to plant and add mulch at 2 to 4 inches deep. As a result, you’ll end up with rich soil to help stabilize the new environment.

A great alternative is a drip irrigation system to slow soak the soil. These prevent over-watering the tree and allow you to irrigate the root ball directly (and occasionally add fertilizer). Fertilizer is essential when growing Hostas under trees because the Hosta will compete for resources with the much larger tree.

Especially with the larger cultivars, fertilizer is necessary to achieve the best size, shape, and glossy sheen on the luxuriant leaves of the Hosta. Hostas are not heavy consumers of nitrogen (N), phosphorus (P), and potassium (K), but because trees, in this case, plant them, they are vying for the same nutrients.

It is ideal for replenishing these nutrients and the trace elements essential to your plant’s health when you grow Hostas under pine trees using a balanced plant fertilizer. After August, fertilizer applications will stimulate new growth when Hostas need lots of soil fertility to prepare for winter dormancy.

Mulch every spring under the pine tree canopy to successfully improve soil structure, prevent soil drying, and retain enough moisture under the pine trees. Decomposing pine needles can be tilled into the soil around pine roots as you add mulch or compost. (Read Sedum Golden Moss Succulent Care)

What Trees Will You Grow Hostas Under?

Here are some common tree types you can grow Hostas under and ones you can’t.

Pine Trees

Growing a Hosta under a pine tree is fine, as the pine tree and the Hosta don’t compete for space. You must apply mulch and organic matter for your Hosta under pine trees.

You may need to fertilize your Hostas to help them grow, as there’s more upkeep under a pine than not under a pine tree. Keep your Hosta well-watered, but don’t over-saturate its roots. The pine tree’s shade will prevent large amounts of water from draining or evaporating from exposure to direct sunlight.

walnut tree

Walnut Trees

Growing Hostas under a walnut tree are also safe. Your Hosta won’t mind if some walnut varieties produce juglone (toxic compounds). Because it’s hardy, and even if the walnut tree absorbs most of the water, it shouldn’t harm your Hosta.

Hostas can grow alongside/under walnut trees in USDA zones 4 through 9, so keep that in mind when planting. It’s common to see Hostas under black walnut trees, as they’re one of the few perennials that can tolerate those conditions.

Maple Trees

For growing Hostas below a maple tree, things can get sticky. Because of shallow tree roots, it’s difficult to grow a Hosta under a maple. Hostas don’t enjoy competing with other plants for ground space. So, don’t work near or under a maple tree. (Learn How Tall Do Snake Plants Get)

Cedar Trees

You can grow Hostas with a “true” cedar tree (like Himalayan cedar). Certain cedar varieties pair well with ground-covering plants, while others don’t.

  • Red cedar (Juniperus virginiana) is another Hosta-friendly cedar. The key is to find cedar trees with noninvasive roots.
  • A cedar’s good canopy can keep a Hosta dry in some climates.
  • In a desert-prone USDA zone, you’ll often need to water a cedar tree above your Hostas to keep the soil moist.
  • If your cedar’s canopy blocks the sun, you’ll need to water your Hostas in a rainier climate.

aspen tree

Aspen Trees

Growing Hostas under aspen trees are hit-or-miss. Aspens have shallow root systems that spread 30 feet from the tree base.

We don’t recommend this pairing because it can harm your Hostas. Also, this can affect how your garden’s soil responds to two separate root systems competing for space and nutrients, but you don’t want to do that. The deeper a tree’s roots, the more successful a Hosta is.

What Perennial Plants Grow Under Pine Trees?

With different blooming stages, perennial plants can live for over two years giving even more flowers to enjoy. The stunning hues of flowers bloom in the spring and summer will astound you. Therefore, having perennial plants will make your garden look elegant and enchanted this time of year.

Under pine trees, many perennial plants can flourish. These plants thrive in the low acidity of the soil and the pine tree’s shade.

Frosted Mouse Ears

It belongs to the group of miniature Hostas. They are thick and curly. They have an asymmetrical margin and a lime green contrast as an addition when planting these.

Golden Tiara:

It has round golden leaves with a golden edge. They grow purple flowers, and the contrast is gorgeous.

Barren Strawberry

A strawberry-like mat of low-growing, dense foliage. Small yellow and purple flowers on a slow-growing plant bloom in the spring.

Sweet Woodruff

Pointy leaves with white spring flowers. Sweet woodruff relieves lung, stomach, and liver pain: blood purifier and insomnia treatment. They can become invasive and eat neighboring plants’ nutrients. In harsh weather, they can go dormant. Sweet woodruff grows best in wet soil, so plant it if you need to cover a large area.

When planting perennials in dry, harsh conditions, water-shaded plants often apply fertilizer more than usual. Pine trees absorb more water and nutrients in such conditions, restricting side or ground plants. As a result, many perennial flowers go dormant at this stage, but proper care will allow them to bloom in late fall or spring.

Cut down branches below pine trees to give shaded plants more light. It works with deciduous trees, pine trees, or old mushrooms but not young evergreen trees. If so, it will mulch the tree instead of deforming it.
