What to Plant Under a Pine Tree?

Planting under a pine tree presents a unique and enchanting opportunity to transform the often shaded and acidic space beneath these majestic giants into a lush and thriving garden. Pine trees, with their evergreen needles and towering presence, create a distinctive environment that requires careful consideration when choosing the right plants. In this article, we’ll explore the art of planting under pine trees, with a focus on shade-tolerant perennials. These plants not only embrace the challenge of shade but also add color, texture, and vitality to the cool, quiet world beneath the pines.

Considerations for Planting under Pine Trees

Before you embark on your garden journey under pine trees, it’s essential to keep some key considerations in mind:

  1. Shade: Understand that pine trees cast deep shade, especially as they mature. This shade limits the amount of sunlight reaching the ground, making it crucial to select plants that can thrive in low-light conditions.
  2. Acidic Soil: Pine trees tend to create acidic soil due to the needles’ decomposition. Test the soil’s pH and amend it if necessary to create a hospitable environment for your chosen plants.
  3. Root Competition: Pine tree roots can be extensive and shallow. Take care when planting to avoid damaging the tree’s root system and select plants that can coexist with these roots.
  4. Moisture Levels: The dense canopy of pine trees can make the soil dry quickly. Be prepared to provide supplemental watering during dry periods to ensure the plants’ health.
  5. Maintenance: Regular maintenance is essential, including mulching, weeding, and occasional fertilization to support the growth of your under-pine garden.

Mulch and Maintenance

Mulching and proper maintenance are crucial for the health and beauty of your garden under pine trees. Here’s what you need to know:

  1. Mulch: Apply a layer of organic mulch, such as pine straw or shredded leaves, around the base of your pine trees and among your plants. Mulch helps conserve soil moisture, suppress weeds, and improve soil quality. Be sure not to mound the mulch against the tree trunk to avoid rot.
  2. Weeding: Regularly check for and remove weeds that may emerge in the garden. Pine straw mulch, in particular, helps in weed suppression, making maintenance more manageable.
  3. Fertilization: Assess the nutrient needs of your chosen plants and provide fertilization as necessary. Pine tree settings may require additional nutrients due to the acidic soil.
  4. Watering: Monitor soil moisture, especially during dry periods. Pine tree canopies can reduce rainfall penetration, so supplemental watering may be required to keep your plants healthy.
  5. Pruning: Trim any dead or unsightly growth from your perennials, ferns, and groundcovers. Pruning helps maintain the appearance of your garden and promotes new growth.

By selecting the right groundcovers and ferns and following a proper maintenance routine, you can ensure that your under-pine garden remains lush, vibrant, and beautiful. The combination of shade-tolerant perennials, groundcovers, and diligent maintenance helps transform the shaded world under your pine trees into a thriving and tranquil woodland retreat.

Wildlife and Bird-Friendly Plants

Planting under pine trees not only enriches the visual appeal of your garden but also provides an opportunity to create a haven for wildlife, including birds and insects. Here are some plant selections that will attract and support local wildlife:

  1. Wild Bergamot (Monarda fistulosa): Wild bergamot, also known as bee balm, produces vibrant pink to lavender flowers that are irresistible to bees, butterflies, and hummingbirds.

  3. Toad Lily (Tricyrtis spp.): Toad lilies feature distinctive, orchid-like blooms that attract pollinators like butterflies and native bees.
  4. Native Grasses: Consider planting native grasses like little bluestem (Schizachyrium scoparium) or switchgrass (Panicum virgatum) to provide habitat for ground-dwelling wildlife.
  5. Bird-Friendly Trees and Shrubs: In addition to the underplanting, adding bird-friendly trees and shrubs nearby, such as serviceberry (Amelanchier) or dogwood (Cornus spp.), can attract a variety of songbirds to your garden.
