Will Leyland Cypress Branches Grow Back? What You Need to Know

Many yards and landscapes have Leyland cypress trees as evergreen privacy trees because they look great. People love their pretty shape, fast growth, and ability to quickly make a thick, opaque screen.

However, these trees do have one significant drawback – their branches will not grow back once removed or damaged. This can lead to frustration when lower branches are pruned or die off from shade, leaving unattractive bare trunks.

So will Leyland cypress branches regrow if cut? Unfortunately, the answer is no. Here’s what you need to know about this issue and how to maintain the beauty of your Leyland cypresses.

Why Leyland Cypress Branches Don’t Regrow

Most conifers lack the ability to produce new shoots along older branches and trunks. This is because they lack adventitious buds – small latent buds that reside under the bark and allow new foliage to sprout out even on bare stems.

Deciduous trees like maples, oaks and fruit trees have adventitious buds, which is why they can quickly leaf out even after major branch damage. Evergreen conifers like Leyland cypress only have active buds on existing green foliage. They do not have dormant adventitious buds waiting to sprout on older bark.

Therefore, once lower branches in a Leyland cypress die off or are pruned back to bare wood, that’s it – no new growth will emerge from those areas again. The tree can only generate new greenery from the tips of existing branches that still have needles.

Preventing Lower Branch Loss

To keep Leyland cypresses from getting ugly bare trunks, it’s important to keep them from losing branches in the first place:

• Site selection: Choose a full sun location and space trees properly to allow light penetration. Insufficient sunlight often causes lower branch dieback.

• Proper care: Water young trees consistently until established. Apply an organic mulch layer to retain moisture. Fertilize annually with a balanced, slow-release formula.

• Pruning with care: Never cut into green leaves, only dead branches Allow 6-10 feet between trees for air circulation.

• Controlling pests and diseases: Keep an eye out for common cypress diseases like canker, root rot, and bagworms. Take action early to maintain good health.

With proper siting, care, and pruning techniques, the lower branches of Leyland cypress can be retained for many years before gradual natural shading occurs.

Recovering From Lost Branches

If your Leyland cypress trees already have significant areas of bare lower trunk with no easy regrowth solution, you have a couple options:

• Replace the tree: If over 50% of the total height is now bare, start over with a healthy new specimen. Remove the existing tree and stump completely before replanting.

• Underplant evergreens: To mask ugly trunks without removing the tree, plant dense evergreen shrubs like boxwoods or hollies that can tolerate shade. Choose varieties that will eventually reach the desired screening height.

Accidental Pruning Damage

Leyland cypress branches will not grow back after improper pruning that removes too much inner foliage. To recover from accidental over-pruning:

• Make clean cut into undamaged wood to encourage quick wound closure.

• Seal large cut wounds with pruning sealer to prevent insect/disease issues.

• Allow time for gradual growth from remaining foliage – don’t over-prune further.

• Provide attentive care like watering and fertilization to encourage new growth.

• Monitor for signs of stress and address any problems immediately.

• Be very patient – it may take 2-3 years for the tree to fully recover dense foliage.

Maintaining Leyland Cypress Beauty

While Leyland cypress branches do not regenerate once lost, proper care from the start can retain their ornamental qualities for many years:

• Choose an appropriate site with full sun.

• Space trees properly and prune regularly for air circulation.

• Provide attentive care when trees are young and establishing.

• Only prune dead branches – never cut into live green foliage.

• Monitor for pests/diseases and address issues before they escalate.

• If lower branches die or are damaged, consider underplanting or replacement.

Leyland cypresses may not regrow lost branches, but following best practices will allow you to enjoy their rapid growth, graceful form, and dense screening abilities while avoiding ugly bare trunks. With some patience and TLC, these elegant evergreens can remain an asset in your landscape for years to come.
