Why Netting for Strawberry Plants is Essential
Keeping birds, slugs, and other garden pests away from ripening strawberries is a common challenge for growers. Netting provides a physical barrier to prevent damage, ensuring more of your hard-earned fruit reaches your plate. Without protection, it is not uncommon for a significant portion of a strawberry crop to be lost to hungry wildlife before it can be picked.
- Netting prevents birds from eating strawberries.
- It deters slugs and snails from reaching the fruit.
- Protects against other garden pests like squirrels.
- Ensures a larger, more successful harvest.
- Maintains fruit quality and cleanliness.
The primary culprits are usually birds, which can decimate a patch in a single morning. However, slugs and snails also pose a threat, especially when plants are low to the ground or growing in pots. Squirrels and other small mammals might also sample your strawberries if given the opportunity. Netting acts as a straightforward, effective deterrent for most common garden invaders.
Beyond simple consumption, pests can also damage the fruit, making it unsightly or unpalatable. Bird pecks create entry points for disease and rot, while slugs leave slime trails and chew holes. A well-applied netting system not only keeps the creatures out but also helps keep the fruit cleaner, reducing the need for extensive washing before consumption.
Understanding Your Adversaries
Identifying the specific threats in your garden is the first step to effective pest management. In the UK, common garden birds like blackbirds, starlings, and sparrows are notorious for enjoying strawberries. Slugs and snails are prevalent in damp conditions, often emerging at dawn and dusk. Larger animals, though less common in urban gardens, might include rabbits or squirrels, particularly in more rural settings.
Consider the size of the mesh when selecting netting. For birds, a mesh size between 10-20mm is typically sufficient. For slugs and snails, finer mesh netting might be more effective, or you might consider other deterrents in conjunction with netting. Smaller mesh can also help prevent insects from reaching the plants, though it may slightly impede pollination if not applied carefully.
The area you are protecting also dictates the type of netting and support system needed. A small patch in a raised bed requires a different approach to covering an extensive ground-level planting or a collection of strawberry plants growing in pots.
When to Deploy Strawberry Plant Netting
The timing of netting is critical. You should ideally erect your netting system as soon as the first flowers appear, or even slightly before. This is because the fruits develop from the flowers, and once the strawberries begin to swell and ripen, they become an irresistible target. Waiting until the berries are red can be too late, as pests may have already discovered your patch.
Once netting is in place, it generally needs to remain until all the fruit has been harvested. Removing it too early risks exposing the developing fruit to pests again. Ensure the netting is secured to prevent birds or slugs from finding their way underneath. This might involve burying the edges slightly, weighing them down with stones or bricks, or tying them securely to the plant supports.
While netting is a robust solution, it's worth noting that it can also slightly reduce light and air circulation to the plants. This is usually a minor issue for strawberries, but it's something to be aware of. After harvest, clean the netting if it is reusable and store it somewhere dry to prolong its lifespan for the following season.
Effective netting is your first line of defence, ensuring a greater proportion of your strawberry harvest is for you, not the local wildlife.
Install netting before the first flowers fully open. This proactive approach prevents pests from developing a taste for your ripening strawberries and ensures continuous protection as the fruit develops.
The installation method will largely depend on the type of netting and the scale of your strawberry patch. For smaller areas, simple hoops and netting can suffice. For larger areas, a more substantial frame might be necessary to keep the netting taut and prevent it from resting directly on the plants, which can allow pests to climb onto the fruit.
Alternatives to Consider
While netting is highly effective, other methods can supplement or, in some cases, substitute for full netting, especially for smaller patches or specific pest issues. These alternatives often focus on different types of deterrents or physical barriers.
One common alternative is using netting in conjunction with other deterrents. For example, reflective tape or scarecrows might deter birds, but their effectiveness can wane as birds become accustomed to them. Shiny objects or old CDs hung among the plants can also have a temporary effect. For slugs and snails, barriers like copper tape, crushed eggshells, or diatomaceous earth can be effective physical deterrents around the base of the plants.
Growing strawberries in pots or containers can sometimes make them easier to protect. You can simply move potted plants to a more sheltered location, or use smaller, custom-fit covers. For larger collections of pots, a dedicated netting structure or a greenhouse/polytunnel offers comprehensive protection.
Companion planting can also play a small role. Some gardeners find that planting strong-smelling herbs near strawberries can help mask the scent, making them less attractive to pests. However, this is generally a supplementary measure rather than a primary solution for significant pest pressure.
The key is to employ a strategy that best suits your garden's specific challenges. A combination of methods often yields the best results, especially when dealing with multiple types of pests. For instance, netting might be your main defence against birds, while copper tape handles slugs.
Choosing the Right Netting Material
The market offers various types of netting, each with its own advantages and suitability for different scenarios. Understanding these differences will help you make an informed choice for your strawberry plants.
Mesh Netting
This is the most common type and is usually made from plastic (polyethylene or polypropylene) or nylon. It comes in different mesh sizes and is often sold in rolls or pre-cut pieces. Mesh netting is generally durable and can be reused for several seasons if cared for properly. The key factor here is the mesh size – fine enough to exclude pests but open enough to allow light and air. It's crucial to choose a mesh that is strong enough not to tear easily, especially if larger animals are a concern, though for strawberries, the primary threat is birds and invertebrates.
Netting Kits and Frames
For a more structured approach, dedicated netting kits are available. These typically include netting along with poles, hoops, or a frame to create a tent-like structure over the plants. These systems keep the netting elevated, preventing direct contact with the fruit and making it easier to access plants for watering or harvesting without fully dismantling the protection. They are particularly useful for protecting a dedicated strawberry patch or raised beds, offering a tidy and efficient solution. Building your own frame using PVC pipes, bamboo canes, or timber is also a popular DIY option.
Fine Insect Netting
If your primary concern is smaller pests like aphids or certain types of flies, or if you're growing strawberries in a greenhouse and want to prevent pollinator access for specific reasons, very fine insect netting can be used. However, for general protection against birds and slugs, standard garden netting is usually sufficient and offers better air and light penetration.
Mulch Layers and Ground Cover
While not strictly 'netting', some gardeners use thick layers of straw or special ground covers beneath strawberry plants. These raise the fruit slightly off the soil, reducing slug contact and keeping the berries cleaner. Straw also helps retain moisture and suppress weeds. While this offers some protection, it does not deter birds, and slugs can still navigate through dense straw. It is best used as a complementary practice alongside more robust pest control measures.
When selecting, consider the longevity you expect, the ease of installation and removal, and the specific pests you are trying to deter. A heavier-duty, UV-stabilised netting will last longer outdoors than lighter versions. For growing strawberries in pots, smaller, customisable nets can be very convenient.
The ultimate goal is to secure your fruit. Whichever method you choose, ensure it is robust, well-maintained, and appropriately sized for the plants and the pests you are targeting.
Installation Tips for Maximum Efficacy
Proper installation is key to ensuring your netting for strawberry plants performs as intended. A poorly installed net can leave gaps for pests to exploit or become a tangled nuisance.
Creating a Secure Enclosure
For ground-level beds, creating a frame that lifts the netting is highly recommended. This can be as simple as bending garden canes or PVC pipes into hoops and inserting them into the soil around the bed's perimeter. Drape the netting over these hoops, ensuring it extends well beyond the edges of the strawberry patch. You can then secure the netting edges by weighing them down with bricks, stones, or soil, or by using garden pegs. This prevents slugs and birds from crawling underneath.
If your plants are in raised beds, the sides of the bed itself can act as a base for securing the netting. You can attach the netting directly to the top edge of the raised bed using staples, clips, or ties, creating a sealed environment. Alternatively, build a simple wooden frame around the raised bed to support the netting, keeping it elevated.
Netting Strawberry Plants in Pots
For strawberry plants growing in pots, a more localised approach works well. You can purchase pre-made netting covers designed to fit over individual pots or small groupings. These often have an elasticated hem that secures snugly around the pot's rim. For larger pots or multiple pots, you might adapt a hoop system or create a small cage using wire mesh or netting stretched over a simple frame.
Maintaining Tension and Access
Ensure the netting is reasonably taut. Loose netting can sag, allowing pests to reach the fruit more easily and potentially entangling birds or beneficial insects. If using a frame, the netting should stand clear of the plants. If you need to access the plants for watering, weeding, or harvesting, consider installing the netting on a frame with a hinged door or a large enough section that can be temporarily lifted and secured without fully exposing the crop.
Regularly check the netting for any tears or gaps. Small holes can be patched, but significant damage may require replacement. Keeping the netting clean will also prolong its life and prevent diseases from being transferred to your plants.
The effectiveness of your protection hinges on meticulous installation and ongoing checks. Don't underestimate the ingenuity of pests in finding weaknesses in your defence.
Weigh down or bury the edges of your netting. This is a simple but crucial step to prevent ground-dwelling pests like slugs and snails from wriggling underneath, ensuring complete protection for your strawberry plants.
By choosing the appropriate netting and installing it correctly, you can significantly increase your chances of enjoying a bountiful and pest-free strawberry harvest. This straightforward horticultural practice is one of the most rewarding investments for any home grower aiming for delicious, unblemished fruit.
