Chemical control of pests and disease is out. Natural and organic methods are in. If pests are a problem in your garden, it can be tempting to reach for pesticides and chemicals. fortunately there are nature and wildlife friendly ways to control pest populations and protect your plants.
Sticky traps
An important part of pest control, arguably the most important part, is being vigilant and aware of any issues so you can tackle them before they take hold. Sticky traps won’t kill huge amounts of insects. However, they can tackle small amounts and are a great indicator of a problem developing.
Nets
Buy the perfect size you need for your beds plus a bit bigger. Cut edges are very susceptible to fraying so avoid it if possible. Also don’t use brambles to deter slugs because they will get caught and tear (which definitely happened with my brassica net this year).
Use super fine mesh netting to protect from insects, and strong woven mesh to keep birds away. Secure nets properly with no gaps. Don’t unintentionally trap birds and mammals!
Nematodes
Nematodes are a biological control that you water into your growing spaces. This is an example for slugs but they are available for a multitude of pests. Nematodes are microscopic, transparent worms. They feed and multiply inside slugs, leading to them stopping eating your plants and dying…lovely, but effective! they are a perishable product so order when you are ready to apply. Must be applied every 6 weeks, and when soil temperatures are warm.
Cold and frost can damage plants, particularly small seedlings and tender fresh growth. Fortunately there are easy ways to protect your plants and avoid damage.
Fleece
Protect plants by placing garden fleece (a lightweight fabric) over them in cold weather, particularly if frost is expected. Horticultural fleece is often made from non-woven plastic-based material 9including the option linked above), however, Plastic free fleece is now available. this is slightly more expensive but available in different thicknesses and a great more sustainable alternative.
Cloche
Cloches come in all different shapes, sizes and materials, and at vastly different price points. Some are much prettier than others such as this beautiful mini tunnel made from galvanised steel. Adding a cloche over your plants will protect against weather, animals, and pests. I recommend using ground pegs to keep securely in place.
Cold Frame
A cold frame protects your plants from the cold and keeps them warm. Extend your growing season with a cold frame. You can protect plants from the elements, and start seedlings. They can also be used to harden off young plants before moving them to the garden. This one is made from tanalised wood for weatherproofing, and plastic panes to avoid any shattered glass, but can be moved around the garden over your beds to protect plants in thr ground if you want.
Mulch
Mulch is a protective layer of material added to garden beds. Loads of different materials can be used to cover the soil’s surface: wood chippings, leaf mould, manure, card board etc. but I love this soil association approved, organic mulch. Mulching will help lock moisture and warmth into your soil, with the added benefit of suppressing weeds and adding organic material to improve your soil. The best times to mulch are either in Autumn or early Spring.
Companion planting
Companion Planting isn’t just for vegetable growers! This is an organic technique where certain flowers are grown and attract beneficial insects (pollinators or predators of common pests). They can also deter pests from your beloved cut flower patch. You can also utilise other plants to improve your soil structure and nutrient availability. Companion plants help build a beneficial environment for your cut flowers.
Some examples include marigolds which repel underground pests and nasturtiums which deter pests like aphids and whiteflies. These two flowers can also be used in your arrangements, and are available in a variety of aesthetic colours (not just the classic neon orange)
