Question: What Plants Do Not Like Pine Needles

What plants tolerate pine needles?

As pine needles break down, they slightly acidify the soil, making them an excellent landscaping mulch for acid-loving plants, trees and shrubs such as camellias, azaleas, hydrangeas, fuchsias, gardenias, ferns, dogwoods, magnolias, holly and evergreens.

Are pine needles good mulch for tomatoes?

Do not use pine needles for mulch around tomatoes or other plants if the pine needles were piled or stored poorly and smell sour or like sulfur, as this bad mulch can injure or kill plants.

Are pine needles good mulch for vegetable garden?

Many vegetables and herbs thrive in the acid-rich soil conditions created by pine needle mulch. Typically, vegetables prefer soil with a pH level of 6.5 to 7 and pine needle mulch helps create such acidic conditions. Both potatoes and garlic fare well in acidic soil and garlic can grow even during mild winters.

Do Hydrangeas like pine needles?

Shrubs that benefit from pine needle mulch include azalea, gardenia, hydrangea, jasmine, rhododendron, bayberry, Daphne rose and holly. You can replace it with a layer of pine needles smoothed around the base of the shrub. Gardeners use an acidic fertilizer to turn hydrangea’s flowers blue.

Do roses like pine needles?

Pine needles interlock and stay in place better on slopes. If the pH of your soil is high, pine needles may lower it. This is especially beneficial in California soils, which typically have neutral soil pH and need acidification to lower the pH to the 6.2 to 6.8 pH preferred by roses.

Do lilacs like pine needles?

Use collected pine needles around fire- resistant plants like roses, lilacs, rhododendrons, azaleas, and distyliums.

Are pine needles toxic to other plants?

A myth exists that this gradually causes the soil to become acidic, killing nearby plants. In fact, however, pine tree needles barely affect the soil pH even when worked into the soil for that purpose. The real problem lies in whether other plants can survive having a mulch of pine tree needles around them.

Are pine needles good for compost?

Soaking the ground needles in water for 24 hours makes them easier to compost. Because pine needles are resistant to composting it helps to use “hot” composting techniques. That means using hot greens which are very high in nitrogen such as grains, manure, coffee grounds or blood meal.

Are pine needles good for strawberries?

Pine needles, also called pine straw, are a proper mulch for strawberries and slightly increase the acidity of the soil as they decompose. Plastic mulch creates an ideal, moist environment for the slimy creatures, but sharp and prickly pine needles protect strawberry plants from slugs.

Are pine needles good for raised garden beds?

If you are looking to raise acidity levels in your garden soil, using pine needles as mulch is a great option. During heavy rain, pine needles tend to stay put and do not wash away making them a great choice for sloped gardens.

Does lavender like pine needles?

Lavender isn’t fussy about soil pH; though it prefers neutral to alkaline soil, it can survive in acidic soil. 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.

Do camellias like pine needles?

Azaleas, Rhododendrons and Camellias Mulching with pine needles ensures proper pH soil levels for azaleas and rhododendrons throughout the growing season. Broad-leafed hostas—also acid-loving plants—do well with a thick layer of pine needles spread around the base of each plant.

Can you plant azaleas under pine trees?

Azaleas and rhododendrons thrive in the acidic soil that is common under pine trees. The environment under trees shades the plants; also, the pines drop needles that act as an organic mulch and keep the soil at an acidic pH.

Can you put pine straw around rose bushes?

Add a two to four inch layer of organic mulch (wood chips, grass clippings, compost, straw, pine needles, or leaves) around the base of each rose bush. Its benefits include: weed deterrence, improved garden appearance and reduced moisture loss (see Mulching for a Healthy Landscape).

Can I use pine needles to mulch blueberries?

Yes. Mulch should be loose enough for water percolation. Pine needles, wood chips or bark mulch work well as mulches for blueberries.

Are pine needles bad for mulch?

MYTH: Ponderosa pine needles make the soil more acidic (low pH). They are a good mulching material that will keep the moisture in, suppress weeds and eventually add nutrients back to the soil. You can also add them to a compost pile; they will slowly break down over time.

Do Blackberries like pine needles?

Using pine needles as your blackberry mulch creates a forest-like appearance in your garden — they actually entangle themselves randomly for better stability on the ground surface. For a solid barrier against weeds and moisture loss, spread the pine needles up to 4 inches deep around the blackberry plants.

Are pine needles good for hostas?

Hostas. Broad-leafed hostas, also acid-loving plants, do well with a thick layer of pine needles spread around the base of each plant. Not only will the mulch keep the soil moist, but it will also provide a pleasing contrast to the lush blue-greens, greens and yellow-golds of different hosta varieties.
