Raspberry bushes can quickly get out of control due to their rapid growth rate and ability to spread through root runners and tip layering. While they produce delicious berries overgrown raspberry patches can take over large areas of your yard and gardens. Removing established raspberry bushes takes effort and diligence but it can be done when using the proper techniques.
Why You May Need to Remove Raspberry Bushes
There are several common reasons you may need to eliminate raspberry bushes from your landscaping
-
Uncontrolled Spread – Raspberry bushes multiply rapidly through root suckers and canes that take root when they touch the ground. They can expand several feet per year, crowding out desired plants.
-
Invasive Growth – Raspberry canes often creep under fences and pop up in unwanted areas like flower beds, lawns, or vegetable gardens. Their thorns make them difficult to control.
-
Lack of Care – Without annual pruning and training, raspberry bushes become an impenetrable bramble with reduced berry production.
-
Disease or Pests – Viruses, fungus, and insects can infest neglected raspberry patches, necessitating removal.
-
Change in Landscaping Plans – Converting a garden layout may require eliminating existing raspberry plants.
-
Preparing for Sale of a Property – Overgrown raspberries detract from curb appeal, so new owners often want them removed.
When to Remove Raspberry Bushes for Best Results
For optimal removal success, plan to take out raspberry bushes when they are dormant in late fall or winter for several reasons:
-
Leafless canes allow better herbicide penetration and root identification.
-
Root nutrient reserves are lowest, improving effectiveness of root cutting.
-
Easier to spot and dig out roots when foliage is gone.
-
Avoid damaging desired plants with chemical exposure.
-
Prevent seeds from sprouting when disposing of ripe fruit.
While removal is possible at other times, eradication will likely take longer and be less effective than during optimal winter timing.
Manual Removal Techniques
Manually digging up raspberry bushes is labor intensive but avoids using herbicides. Follow these steps:
-
Cut back the canes about 6 inches above soil level using loppers or a hedge trimmer. Wear protective gloves and clothes.
-
Loosen the soil with a shovel, pickaxe, or garden fork. Dig around the plant’s root crown and extract it along with large roots.
-
Thoroughly excavate the area, removing any remaining roots. Even small root sections can generate new growth.
-
Monitor the site weekly and promptly remove any regrowth before plants establish. Persistence is key.
While extremely effective if done properly, manual removal requires considerable time and effort. Using herbicides is less labor intensive.
Using Chemicals to Kill Raspberry Bushes
Glyphosate or triclopyr herbicides effectively kill raspberry bushes while breaking down safely in soil after. Note these key points:
-
Glyphosate is a non-selective systemic herbicide that kills all plant types. Only use where bare soil is acceptable.
-
Triclopyr targets broadleaf plants like raspberries but spares grasses. Use it around desirable grassy plants.
-
Apply herbicides during dormancy when canes have leaves for best absorption.
-
Avoid contact with wanted trees or shrubs when spraying.
-
Wear protective equipment like gloves, goggles, and a mask during application.
-
Expect to make follow-up applications as roots resprout. Persistence is imperative.
With proper application on actively growing foliage, herbicides provide excellent raspberry bush control with less labor than manual techniques.
Follow-Up Care After Raspberry Bush Removal
Removing raspberry bushes is not a one-time project. Expect to manage regrowth for several years as the root system dies out. Here are some effective follow-up steps:
-
Monitor weekly for new shoots and remove immediately when spotted.
-
Apply mulch or landscape fabric to smother any growth. Glyphosate can penetrate mulch.
-
Reapply herbicide on any resprouts.
-
Avoid composting removed canes as they may sprout when buried.
-
Test and amend soil pH if needed since raspberries prefer slightly acidic conditions.
With persistence, the root network will eventually die off and stop generating new shoots. But eliminating established plants takes an ongoing time commitment.
Tackling Large Raspberry Infestations
For properties with extensive raspberry growth covering a wide area, removal can be especially challenging. Here are some tips:
-
Work in manageable sections for steady progress.
-
Use machinery like a bobcat or backhoe to extract roots if digging manually.
-
Combine manual digging and herbicide treatments for best results.
-
Hire experienced landscaping crews if warranted by the extent of growth.
-
Budget adequate time, labor, and supplies to complete the process.
-
Be patient – eradicating a large area takes time but persistence pays off.
Prevention After Raspberry Bush Removal
Once you invest significant effort removing raspberry bushes, you’ll want to prevent recurrence. Here are some useful tips:
-
Plant competitive groundcovers like juniper, ivy, or periwinkle to retard growth.
-
Install underground barrier products around remaining plants or property edges.
-
Properly manage established raspberry patches with pruning, training, and renewal pruning.
-
Quickly eliminate shoots sprouting outside designated planting beds.
-
Prevent canes from rooting where they contact the ground and spreading.
With some prevention measures, you can contain raspberries and avoid having to remove them again in the future.
Eliminating overgrown raspberry bushes requires commitment and diligence, but following proper manual and chemical removal techniques can successfully conquer even dense infestations. Persistent monitoring and maintenance will keep subsequent growth under control so you can reclaim your property from rampant raspberries. With patience and diligence, you can rid your landscape of unwanted raspberry bushes.
StepsMethod
- 1 Put on heavy-duty gardening gloves and wear a long-sleeved shirt. You should also wear pants instead of shorts. Raspberry canes are the thorny branches of the plant and they can easily snag on lightweight fabric or bare skin.[1]
- Wear covered shoes or boots instead of sandals. Its really easy to accidentally step on thorns as you clear the raspberry bushes away.
- 2 Use a weed eater or pruning shears to cut each cane 1 foot (0.30 m) from the ground. A weed eater is handy if youre clearing a large area of raspberry bushes. If you dont have this tool, you could use a hedge trimmer or even a pair of pruning shears. The main goal is to cut each cane down close to the ground.[2]
- If youre using a weed eater, wear hearing protection so you dont damage your ears.

- 3 Use a shovel to dig up the stump of each raspberry bush. The canes that you trimmed all stem from a thick stump that contains the roots for the plants. Push your shovel into the soil around the entire stump. Then, pull the stump out.[3]
- Old or large raspberry bushes can have big root systems, so you may want to ask a friend to help you dig out the stump.
- It can help to loosen the soil around the stump with a garden fork.
- 4 Dig out roots that remain in the soil. Try to remove every part of the raspberry bush, including small or new root growth. Then, fill in the soil to make the ground level. To prevent the plant from coming back, check the area every week and pull up small seedlings that you find.[4]
- Its a lot easier to remove small raspberry plant growth than it is to remove a large overgrown plant.
- 5 Spread black plastic over exposed roots to act as a barrier. If the raspberry plant is spreading from your neighbors yard or you cant access the stump, lay down a sheet of heavy black plastic and weigh down the sides with rocks. Leave the plastic in place for 4 to 6 weeks, so the heat and lack of sunlight kill the roots.[5]
- 6 Cover the area with newspaper and mulch to prevent weeds from growing. Spread a layer of cardboard or several layers of newspaper over the space. Then, spread 3 inches (7.6 cm) of mulch over the cardboard or newspaper. This suppresses weeds and breaks down over time, which adds bulk to the soil.
- It can take a few years to completely kill a raspberry bush. Continue to keep a close eye on this area and pull young raspberry growth as soon as you see it.
- 7 Mulch or burn the raspberry canes and stumps. Rake up all of the raspberry canes. If youve got a lot of raspberry canes and you dont want to waste them, run them through a wood chipper. Then, you can spread this mulch in your garden. If you dont want to use them as mulch, gather the canes in a pile and burn them. Do not compost the canes or raspberries might grow in your heap.[6]
- If you dont want to mulch or burn the raspberry canes, you can usually put them in your yard waste bin or donate them to a community garden.
- If the bushes currently have raspberries on them, check the ground for fallen fruit. Since the raspberries contain seeds, you dont want them staying in the soil.
