By now you’ve probably read my first post on gardening: Vegetable Gardening for Beginners . One of the things that can defeat a new gardener faster than anything else (I know it sure would defeat me!) is waging war with all the garden pests that want to take over your veggies and prevent you from ever getting your first good harvest. For that reason I’m adding this second installment on my post about gardening, and calling it Natural Remedies for Garden Pests.
But I’m confessing right up front that I don’t have all the answers (very few of them in fact) about this war on garden pests. So in this post I’m going to give you a list of what many experienced gardeners believe to be the 12 biggest garden pests, and add a round-table blog with each that helps us to see a way that we can be successful in the war against that pest.
Here are a few natural alternatives to pest control that you will see mentioned in many of these posts:
- Diatomaceous Earth – a soft, crumbly, porous sedimentary deposit formed from the fossil remains of diatoms
- Plant Collars – protects slugs and other pests from getting on the plant
- Borax & Sugar – used to kill ants around the base of the plant
- Row Covers – protects young plants
- Natural Dish Washing Liquid – used to make homemade pest spray
- Bt Spray – an organic formulation that kills insects and larvae
- Dipel Dust – used by commercial organic growers to control insects on vegetables.
- Japanese Beetle Trap – uses a pheromone and catches the beetles and traps them.
- Spinosad – an organic insect spray
- Essential Oils ( where to buy ) – rosemary, melaleuca, peppermint, thyme are just a few essential oils you can use that can help with garden insects. Here’s 9 clever ways to use essential oils on your home garden!
