Combatting Slugs, Snails, and Squirrels

The green-thumbed amongst us know all too well the damage that can be wrought by our seemingly harmless garden companions – slugs, snails, and squirrels. All that hard work and patience, the joy of watching your blooms grow, can be decimated overnight by these persistent critters. But don’t despair, fellow gardeners. There are ways to protect your plants and enjoy the fruits (and flowers) of your labour. Let’s delve into the what, why, and how of this garden warfare.

Understanding the Enemy: Slugs and Snails

Slugs and snails, gastropods hailing from the mollusc family, are a common sight and a formidable foe in many a UK garden. Notorious for their insatiable appetite for plants, these critters are known to wreak havoc in green spaces, and understanding their biology, habits, and preferences is the first step in managing their threat to your beloved plants.

Anatomy and Physiology

While they might seem similar at a glance, there is a key difference between slugs and snails: the shell. Snails carry a coiled shell on their backs, which they retreat into if threatened or during dry conditions. Slugs, however, have a small, hard internal structure that doesn’t offer the same protection.

Both slugs and snails are hermaphrodites, which means they have both male and female reproductive organs. As a result, they reproduce rapidly and efficiently, leading to swift infestations in your garden. Their soft, slimy bodies enable them to move across various surfaces as they glide along their self-produced mucus, leaving a characteristic silvery trail in their wake.

Diet and Habits

These creatures are particularly attracted to leafy vegetables such as lettuce, beans, cabbage, and marigolds and tender herbs like basil. They’re known to have a particular fondness for young, tender growth and succulent foliage, feasting on them with a rasping tongue. Their nocturnal nature means they’re most active during the night, making the most of damp, overcast conditions which prevent them from drying out. On sunny days, they tend to hide in cool, moist areas such as under plant pots, debris, or in the crevices of walls.

Damage and Telltale Signs

The damage they inflict on your garden is both significant and unmistakable. Slugs and snails feast on the leaves, stems, and plant bulbs, leaving behind irregular, ragged holes and chewed edges. They can completely decimate young seedlings overnight and severely weaken more established plants. The silvery slime trail they leave behind as they move around your garden is a clear sign of their nocturnal feast and an indication of their presence.

So, with a comprehensive understanding of slugs and snails, we can move forward with knowledge and purpose, ready to defend our precious gardens from these voracious gastropods.

Battling Slugs and Snails

1. Handpicking: One of the simplest methods is to handpick these pests from your plants. Don a pair of gloves and inspect your plants at dusk or dawn. Be sure to check the undersides of leaves and the base of the plant. Dispose of them far from your garden or in a sealed container.

2. Beer Traps: Slugs and snails are oddly attracted to beer. Bury a cup or jar in your garden, leaving the rim at soil level, and fill it with beer. The molluscs will crawl in and drown.

3. Barriers and Repellents: Create barriers using crushed eggshells or copper tape around your plants. The sharp edges of the eggshells and the small electric charge produced by copper deter these pests.

4. Natural Predators: Encourage natural predators like birds, hedgehogs, and beetles into your garden. A biodiversity-rich garden is often the best defence.

The Squirrel Scourge

Our bushy-tailed friends might look cute and harmless, but they can be quite the menace in your garden, especially if you have planted bulbs. Squirrels have a penchant for tulip bulbs and crocus corms, and they’ll dig them up for a quick snack. They are also known to strip bark from trees, damaging them in the process.

Outsmarting Squirrels

1. Squirrel-Proof Bulb Planting: Plant your bulbs deeply, around 3-4 times the bulb’s height, and cover the area with a wire mesh. You could also consider using bulb cages. 

2. Use Squirrel-Resistant Bulbs: Squirrels tend to avoid certain bulbs, such as daffodils, alliums, and hyacinths. Including these in your garden can save your precious tulips.

3. Squirrel Feeders: If you can’t beat them, feed them! Providing an alternative food source might keep them away from your plants.

In conclusion, fellow gardeners, while slugs, snails, and squirrels can pose a real challenge to our horticultural ambitions, remember they are part of our ecosystem, and we share this space with them. By understanding their habits and preferences, we can devise strategies to protect our gardens. It might take a bit of effort, but when you see your plants flourishing, free from holes and nibbles, you’ll know it was worth it. So, let’s reclaim our gardens, one mollusc and squirrel at a time!
