Landscaping Under Pine Trees: Basic Tips With List of Plants Suitable to Grow Beneath Pines

Landscaping with plants, ferns, and grasses is one of the most artistic ways to utilize any open area under pine trees in your garden. Instead of using stones, bricks, or rubber mulch, you can add more vibrancy to the place with flowering plants and shrubs that improve the entire surrounding.

General Conditions Under a Pine Tree and What You Can Do to Make it More Favorable

The soil surrounding pine trees may sometimes be challenging for growing other plants, as the soil is often mildly acidic. Other issues like dense shade and lack of moisture due to their tall height and thick branches can also add to the point. To deal with these challenges, you need to consider the following:

Soil

Firstly, contrary to the general belief, fresh pine needles do not drastically change the acidity of the ground. As the falling needles are  only slightly acidic, possessing a pH of 3.2 to 3.8, they change the soil, pH only slightly, without proving to be harmful to any surrounding plants

  • You may consider adding limestone powder to the soil if you still believe the soil is too acidic for other plants. Apply at a ratio of 25lbs of lime per 1,000 sq ft area, starting about a year before you plant the ground cover plants.
  • You may also consider digging out the acidic soil replacing it with clean surface soil. However, make sure not to damage the roots of the pines in any way.

These measures are pretty drastic, so before employing either, consider testing the soil to find out whether it is too acidic for other plants.

Light

As the thick foliages cover the entire area below, it is often quite shaded and damp under pines.

  • Cut the lower branches of the pine tree so that the sun can filter down the tree to the adjacent soil. It will help the plants and shrubs to get enough light for their growth.

Water

The evergreen pine trees absorb a lot of water, so it can pose a problem for plants, ferns, and grasses growing beneath it as there is often not enough water left for them to absorb and sustain themselves.

  • Provide sufficient water to the surrounding plants growing in the same soil for at least in the preliminary year of their growth. It will help them establish suitably with additional water.
  • Remove any dried up branches, pebbles, and weeds to help the adjoining plants to absorb the essential moisture from the soil.
  • Prune the pine needles and branches regularly so the rainwater may reach down to the very base. It will allow the neighboring plants to take in the excess moisture.

Things to Consider When Choosing Plants for Landscaping Under a Pine Tree

Select plants and grasses that suit the partial to full shade conditions love acidic, well-drained soils and grows best in relatively arid conditions with less water.
