It’s time to wage war on Slugs and Snails! They will be looking for a tasty morsel now the weather is warming up. They are active overnight and can destroy a row of seedlings while you are sleeping! If like me, you have children, animals or chickens running around the garden you won’t want to be putting anything nasty down to eradicate them and I tend to shy away from going out in the dark, torch in hand to pick them up and dispose of them - yuk!
It is important to fight this battle with everything you can muster before these slimy molluscs can establish a real stronghold in your garden. You will never eradicate them completely and they do play their part in the ecosystem of any garden but keeping them down to manageable numbers is definitely my preferred action!
By far and away the simplest way to deal with them I find is with a Biological Control, Nemaslug containstiny microscopic organisms, naturally occurring nematodes (Phasmarhabditis hermaphrodita) and controls all common species of small to medium sized slugs (up to 8cm - 2½-3 inches) both above and below ground.
You simply mix it with water and water into the soil beneath your plants with a watering can. One application of Nemaslug provides 300,000 nematodes for every square metre of soil, giving at least six weeks control of slugs! This is generally enough time for seedlings and plants to get well established. Nemaslug is easy to apply and does not leave any unsightly residues. The majority of the slugs will die underground, so don't expect to see too many bodies lying around! Apply Nemaslug to moist soil. The soil temperature needs to be 5ºC (40ºF) or above when you apply but this is also when plants naturally start growing. Nematodes are capable of surviving the odd frost, so don't worry if the temperature falls after you have applied it, these nematodes are completely harmless to birds, animals and children.
There is a whole range of Biological Controls for most common garden pests including Nemasys for Vine Weevil control, Leatherjacket Killer and Grow Your Own which targets a broad range of destructive garden pests.
