The Ultimate Purple Evergreen Shrub Planting Guide

You’ve picked your plant—now it’s time to give it the best possible start in life. Following this simple planting guide will set your shrub up for years of health and beauty. Learning how to purple evergreen shrub is all about getting the foundation right.

1. Choose the Right Spot

This is the most critical step! Re-read the sun and soil requirements for your specific shrub. Most purple-leafed varieties need at least 6 hours of direct sun to develop their deepest, richest color. Also, consider the mature size of the plant—don’t plant a 10-foot shrub right under a low window!

2. Prepare the Soil

Most shrubs thrive in well-drained soil. If you have heavy clay, you’ll need to amend it. Dig a hole that is twice as wide as the root ball but only as deep. Mix the soil you removed with some good quality compost. This improves drainage and adds vital nutrients.

3. The Step-by-Step Planting Process

  1. Gently remove the shrub from its container. If the roots are tightly wound (root-bound), carefully tease them apart with your fingers to encourage them to grow outward.
  2. Place the shrub in the center of the hole. The top of the root ball should be level with or slightly above the surrounding ground. Never plant it too deep!
  3. Backfill the hole with the amended soil, gently tamping it down to remove air pockets.
  4. Create a small “moat” or berm of soil around the base of the plant to help hold water.
  5. Water deeply and thoroughly right after planting. This helps settle the soil around the roots.
  6. Apply a 2-3 inch layer of mulch (like bark chips or shredded leaves) around the base, but be sure to keep it from touching the main stem to prevent rot.

Essential Care for Lasting Color: Your Purple Evergreen Shrub Care Guide

You’ve done the hard part! Now, let’s cover the simple ongoing care that will keep your purple evergreen looking its best. This is where we apply some purple evergreen shrub best practices.

Watering Wisely

For the first year, your shrub needs consistent moisture to establish a strong root system. Water deeply once or twice a week, especially during hot, dry spells. Once established, most evergreens are quite drought-tolerant. Always check the soil—if it’s dry a few inches down, it’s time to water.

Feeding for Vibrant Foliage

Less is more when it comes to fertilizer. Feed your shrub in the early spring with a slow-release fertilizer formulated for trees and shrubs. For acid-loving plants like Rhododendrons and Loropetalum, use a fertilizer specifically for them. A yearly application of compost is also a wonderful, natural boost.

Pruning for Shape and Health

The best time to prune most evergreen shrubs is right after they finish flowering in the spring. This avoids cutting off next year’s flower buds. You can lightly trim to maintain shape, remove any dead or damaged branches, and improve air circulation. Avoid heavy pruning in the late fall, as this can encourage tender new growth that gets damaged by frost.

Troubleshooting: Common Problems with Purple Evergreen Shrubs

Even the toughest plants can run into issues. Don’t panic! Here are some common problems with purple evergreen shrub and how to easily solve them. These simple purple evergreen shrub tips will help you navigate any challenge.

  • Problem: The leaves are turning green.
    Solution: This is almost always a sign of not enough sunlight. The plant needs sun to produce the pigments that create that beautiful purple color. If possible, move it to a sunnier spot. If not, accept that it will be a greener version.
  • Problem: The leaves are brown and crispy at the edges.
    Solution: This usually indicates “winter burn,” caused by harsh winter winds and sun when the ground is frozen. Ensure the plant is well-watered leading into winter and apply a good layer of mulch to insulate the roots. In very exposed sites, a burlap windbreak can help.
  • Problem: The plant looks sparse and leggy.
    Solution: It likely needs more light and a good pruning. After it flowers, selectively trim back some of the longest branches to encourage bushier, denser growth from the interior of the plant.

Gardening with a Conscience: Sustainable and Eco-Friendly Practices

A beautiful garden can also be a healthy one for our planet. Embracing a sustainable purple evergreen shrub approach is easy and rewarding. An eco-friendly purple evergreen shrub is one that thrives with minimal intervention.

Choose the Right Plant for the Right Place: By matching a plant to your specific conditions, you drastically reduce the need for water, fertilizer, and pesticides.

Mulch, Mulch, Mulch: A layer of organic mulch conserves soil moisture (less watering!), suppresses weeds (no herbicides!), and breaks down over time to feed the soil naturally.

Water Smart: Water deeply but infrequently to encourage deep roots. Using a soaker hose or drip irrigation delivers water directly to the roots, minimizing evaporation.

Embrace Imperfection: A few chewed leaves are not a catastrophe; they’re a sign that your garden is part of a healthy ecosystem! Avoid reaching for chemical pesticides unless absolutely necessary.

Frequently Asked Questions About Purple Evergreen Shrubs

Will my purple evergreen shrub stay purple all year?

For the most part, yes! Plants like Loropetalum hold their deep purple color year-round. Others, like the ‘PJM’ Rhododendron, have green summer foliage that transforms to a rich purple in the fall and winter. Always check the plant tag for its specific seasonal color characteristics.

How fast do these shrubs grow?

Growth rate varies by type. Hebes are generally slow and compact growers. Loropetalum can be quite fast, with some varieties growing over a foot per year. Junipers and Rhododendrons typically have a moderate growth rate. Your plant’s tag will usually list its expected growth rate.

Can I grow a purple evergreen shrub in a container?

Absolutely! Compact varieties of Hebe, Loropetalum, and even some dwarf junipers are fantastic in containers. Just be sure to use a large pot with excellent drainage holes and a quality potting mix. Remember that container plants will need more frequent watering than those in the ground.

What are the best companion plants for purple evergreens?

The beauty of purple is how well it pairs with other colors! For a stunning contrast, plant them near chartreuse or golden-yellow foliage plants like ‘Gold Mop’ Cypress or Golden Creeping Jenny. They also look beautiful next to plants with silvery foliage, like Lamb’s Ear or Artemisia.
