Organic Pesticides for plant at reasonable cost

[Metaphor]

Hello All, can anyone recommend a good pesticides for controlling weeds and insects that are damaging my plants such a cauliflower, whose leaves are being eaten by insects in my allotment. Also where can i purchase it on a reasonable prices? it is frustrating to see all my hard work gong waste.😢

Pesticides don’t control weeds. It’s best to just dig them out and keep on top of them. There are soap mixtures you can make-up (you’ll find recipes on Google), or you can buy natural pesticides for bugs. I put soft fine nets over fruit and veg to stop birds and cabbage white butterflies from laying eggs that become caterpillar munching machines. I do lose some plants to slugs and snails, but (with gritted teeth) I take it on the chin. I don’t use any synthetic chemicals in my garden. After a few years, nature mostly balances things out. Birds eat the insects etc.

Agree with PP - IME you need to net cauliflowers. There's not much way round it.

Weeding is a manual job and the more regularly you do it the easier it is and the easier it gets (because you remove them before they set seed so you have less of a perennial issue).

Slugs and snails - the best thing here is look at where they are hiding and what can be done to open it up so they don't have nearby spots to shelter in during the hot daytime.

Get good garden covers. That will keep pests off (though will also prevent good insects getting in to help with pollination. I use garden covers. I'm not sure there is an organic answer to weeds. Organic is more work, but I wouldn't want to be using herbicides around food I'm going to eat either. I have heard pouring boiling water on weeds can kill them (never found it worked for me) but that could affect the plants they are near. Mulching can be a good way to keep weeds controlled.
