Gardening expert shares garlic hack for deterring slugs that ‘gardeners swear by’

0


Slugs are a common pest in British gardens and can devastate crops and plants. They usually leave large holes in tender leaves and flowers or leave a silvery slime on nearby ground. Some seedlings can be left with just stems after a particularly bad attack.

“You can make a drench yourself by crushing two whole garlic bulbs and boiling them in a couple of pints of water, then strain and cool.

“Dilute one tablespoon in four litres of water then put over your young plants once a week in the evening.”

Some methods for making a garlic slug deterrent are more complex.

One method you can use is mincing four cloves of garlic to a tablespoon of mineral oil.

Shake the mix together and then use on your soil.

If you’re uncertain if the mixture is going to damage your plants, you can test it on a small, inconspicuous hidden part of the plant and wait a day or two.

Yellowing leaves or other damage means you may need to further dilute the solution.
