Will Grass Grow in The Shady Areas Around the Pine Tree?
Pine trees are known for their appealing cone shape. They look impeccable in a well-kept garden or landscape. Many people do not think grass can be grown under a pine tree, which is mostly true unless you pick the right type of grass. Depending on your climate, see the following grasses to grow under pines:
Grasses for cooler zones with a temperature span of 65 to 80 degrees in the spring:
- Fescue – A popular landscaping grass; it loves the shade and does not need mowing.
- Rough Blue Grass – This grass does well in shaded areas and is quite hearty.
- Perennial Rye Grass – It thrives in the shade but likes filtered, not deep shade.
Grasses for warmer zones with a temperature of 80 degrees or more in the spring:
- Zoysia – This grass is dense and will work in shady areas
- St. Augustine – This grass is one of the most shade tolerant and is very thick
- Centipede – This grass creeps as it grows and tolerates shade or sun
As you can see, there are choices for grass that will successfully grow.
What is the Proper pH Level for Acidic Soil?
Before you choose which plants, ground covers or grass to plant under your pine trees, take into account how the pine tree affects the soil and area directly underneath it. Knowing the conditions that the plant will face, will allow you to have a plan in action and allow you to choose the best plant or ground cover for your situation.
The acidity of the soil comes from the roots of the tree. The ground is 4.5 – 5.0 pH under pine trees. Pine needles have a pH level of 3.2 – 3.8 when it falls to the ground. The needles will not affect the soil’s pH level; they make excellent mulch and help keep moisture around the plants.
Because the pine tree branches block water from getting to the ground, it tends to be dry underneath. This dryness means you will need to water your plants frequently or install a drip irrigation system. You could also place some peat moss around the plants, as this will help retain water.
If you believe the soil is too still too acidic, which would be below 4.5 pH, upon testing acidity levels, try the following:
- Add limestone powder to the soil. Apply a ratio of 25 lbs of lime per 1000 square foot area. Do this a year before planting anything under the pine tree.
- Dig out the acidic soil and replace it with clean surface soil. Be cautious not to injure the roots of the pine tree.
Watching the soil’s acidity is an essential factor and will dictate the health of your tree and what plants you choose to place there. Now that the soil is good to go, you should choose your plants./ground cover.
Many ground covers and few grass varieties can grow under pine trees as we’ve shown above. With a bit of learning and ingenuity, you can find the ideal plants or ground covers for your landscape.
