What Does It Mean to Cut Back to Basal Foliage? The Ultimate Guide

Cutting back to basal foliage is an important gardening technique for maintaining shrubs, trees, perennials, and other plants. But what exactly does it mean? Read on for a complete guide to properly cutting back growth to the base of a plant.

What is Basal Foliage?

Basal foliage refers to the leaves, stems, and shoots that emerge directly from the base or origin of a plant. This includes growth coming from the crown, soil level, or right above the root system. Basal foliage comprises the foundational structure that supports the rest of the plant.

On many plants, basal foliage looks slightly different than leaves and stems further up. It may be a different color, texture, or thickness. Basal growth is the plant‘s source of energy and nutrients from the roots. It also houses buds that will produce new stems and foliage.

When to Cut Back to Basal Foliage

Cutting back to basal foliage can be done for several reasons:

• To rejuvenate old shrubs and encourage new, healthy growth from the base
• To remove dead, damaged, or diseased stems
• To control rampant growth and reshape or reduce the size of a plant
• To thin dense growth to improve air circulation and light exposure
• To promote fuller, bushier growth through new basal shoot development

Timing is important when cutting back to basal foliage:

• Spring: Best time for rejuvenation pruning of overgrown shrubs and trees. Avoid early spring frosts.
• Summer: Allow time for new growth to harden off before winter. Stop 6-8 weeks before first fall frost.
• Fall: Appropriate for removing spent foliage and stems after flowering.
• Winter: Avoid pruning when plants are dormant. Spring is better for rejuvenation pruning.

How to Cut Back to Basal Foliage

Follow these steps for proper cut back to basal foliage:

Gather Necessary Tools

• Bypass hand pruners for smaller stems
• Loppers for thicker stems
• Pruning saw for large diameter branches
• Disinfect tools before use with diluted bleach solution

Identify Basal Growth

• Locate stems emerging from the base or crown of plant
• Distinguish from secondary stems branching off later
• Look for swollen basal bulge at soil line

Make Proper Pruning Cuts

• Cut main upright stems back to just above soil line
• Angle cuts slightly downwards away from buds
• Leave no stub and prune just above a bud eye
• Remove only 1/3 of living stems at one time
• Disinfect tools between cuts

Provide Aftercare

• Water well after significant pruning
• Mulch around base of plant
• Stake large cut back shrubs if needed for support
• Monitor for new growth in following weeks

Techniques for Cutting Back to Basal Foliage

Specific techniques like coppicing and pollarding involve cutting woody plants back to basal foliage to stimulate new growth.

• Coppicing: Cutting tree stems back to the ground to produce new shoots from the stool or stump. Done every few years.

• Pollarding: Similar to coppicing but pruning the stems back to knobs at the same height above ground every year. Common for pollarded trees.

• Grass striping: Mowing lawns to different heights to create a striped pattern. Involves cutting grass back to basal foliage.

Benefits of Cutting Back to Basal Foliage

Cutting back to the base provides many benefits for plant health and growth:

• Rejuvenates old, tired plants by stimulating new basal and root growth
• Removes dead or damaged stems prone to disease/pests
• Opens up interior to light and air circulation
• Controls rampant growth and reshape/reduce plant size
• Encourages bushier, more compact growth habit
• Forces production of new stems and foliage

Precautions When Cutting Back

When cutting back to basal foliage, keep these precautions in mind:

• Never remove more than 30% of living stems at one time
• Avoid cutting back late in fall; new growth may not harden off before winter
• Disinfect tools between plants to prevent disease spread
• Prune selectively rather than shearing off all growth indiscriminately
• Stake large shrubs after significant pruning to prevent stems breaking

Summary

Cutting back to basal foliage means pruning woody plant stems down to the leaves, shoots, and buds emerging from the base or crown of the plant. This gardening technique performed properly and at the right times rejuvenates growth, removes problem stems, and shapes plants by forcing new basal shoot production.
