Here are some perennials that tend to be a good choice to use under pine trees. These plants love the acid soil and the shade and filtered sunlight the trees provide….Perennial flowers that love acid soil

• Columbines.
• Rhododendron.
• Lily of the valley.
• Wild geraniums (cranesbill)
• Jacobs ladder.
• Sweet woodruff.
• Hydrangeas.

Both blueberries (Vaccinium corymbosum) and pine (Pinus spp.) like acidic soil, and both thrive in U.S. Department of Agriculture plant hardiness zones 7 though 10, making them ideal planting partners. The berry plants’ shallow roots won’t bother the pine, and both will enjoy regular irrigation.

Because pine trees typically thrive in slightly acidic soil, plants growing under them should also tolerate this pH to survive. Meanwhile, pine trees can survive in slightly alkaline soil, which is ideal for lavender. Either way, this compatibility makes lavender a viable option for planting under pine trees.

Elephant ears grow from large, egg-shaped tubers, which should be planted at least 6 to 8 inches below the soil surface. Gardeners who want to grow elephant ears under or near pine trees should avoid slicing through tree roots to plant the tubers, seeking out soil pockets between roots instead.

Growing Grass Under Pine Trees Cool season grasses grow in conditions where the temperatures range from 65 to 80 Fahrenheit in early spring or fall. Fescue (Festuca arundinacea), both fine and tall; and bluegrass (Poa pratensis) and ryegrass (Lolium) are the best choices for cool season zones.

These include cabbage; leafy greens like spinach and kale; lettuce; and root vegetables like carrots and potatoes. Vegetables that produce fruit from flowers require the most sun. Those like tomatoes or eggplant need at least eight hours of sun daily to flourish.

Pines prefer an acidic soil of 5.25, while tomatoes grow best in soils ranging from slightly acidic to neutral, 6.0 to 7.5. The soil needed to keep a pine tree healthy might be as much as 2.25 points lower than what is optimum for the type of tomato you are growing.

Can Peonies Grow Under Pine Trees? Peonies are not a good choice for planting under pine trees, as they need full sun, and do not like acidic soil. They do not like to share resources, so do best when planted away from trees or taller shrubs, including pine trees.

Where Not to Plant: Tulips do not grow well in acidic soil, or planted under cedar or pine trees. Be cautious not to plant bulbs under eves of homes or protected areas where the ground does not get the natural winter rains. Ground surface needs moisture.

The ground under evergreens is very acid (the needles) and very shady, also not often doesn’t get enough water. Not very supportive of clover. You could try dead nettle, vinca or bugleweed.

Some flowers, shrubs and trees that do great in pine straw:

• Amaryllis.
• Azaleas.
• Bluebell.
• Camellias.
• Chrysanthemum.
• Columbine.
• Dahlias.
• Daisies.

Pine needles, wood chips or bark mulch work well as mulches for blueberries. Avoid using dyed mulches (black or red).

The iris is among the group of plants and flowers who benefit from pine mulch. Pine needles are acidic when they’re green and may increase acidity in soil, but they become more neutral over time as they decompose.

Pine Needles Can Work as Mulch Pine needles, also known as pine straw, make fine mulch for some flower beds. The biggest knock against pine needles is that they will lower the pH of the soil, making it too acid for plants to grow.

Natural Weed Killer Recipe When looking for a natural alternative to herbicides, a cocktail of vinegar, salt and liquid dish soap has all of the ingredients needed to quickly kill weeds. Acetic acid in the vinegar and the salt are both very good at drawing moisture from weeds.
