Companion planting is about putting plants together which have mutual benefits to each other. It can be an organic way to protect your crops from pests or it could help improve pollination of fruit and vegetable crops. Although there is limited scientific research surrounding companion gardening, many gardeners find it extremely beneficial to their plant’s performance.

I’m also giving this a fair crack of the whip this year….In my garden I’ve got summer savory in amongst the french climbing beans and in the greenhouse on our plot we are trying Toms nestled amongst tagetes and basil (a tad behind but will go in very soon)…on the brassica bed we are planting chamomile and in a few weeks planting anise hyssop, sage & rosemary in amongst the row dividing spaces…will look great anyway so any “nursing” “repelling” etc will be a bonus.
Companion planting is something every organic gardener should practice. I’m always looking to my sources for what to plant next to what. It’s helped tremendously!
