Thanks for sharing, George! I like the clearly presented advice on what to plant when.

I'm curious about the companion planting source data. There's an interesting lack of evidence in the academic literature on a lot of the companion planting combinations. However, growers hold a lot of knowledge. Would love to hear how people get on with different combinations. Especially if things don't work out...

Thanks George this looks like a great resource, some combinations new to me and I specially like the Did You Know tips at the bottom of the page!

The gardens where I volunteer have done a lot of experimental growing procedures including companion planting and it is notable in how we individually have different perceptions of suitable companions. I have always had a touchstone belief in not growing alliums and legumes together but many people have assured me they have grown the two together very successfully on a regular basis. I have begun to believe that the important factor lies in the health of the soil and growing suitable cultivars for the environment.

I do find some of the combinations in companion planting highly entertaining though. For example who seriously would grow raspberries and potatoes together. Spacing must be key in such a concept but I do not recall ever seeing sufficient detail about such matters outside research station literature.

That looks useful!

Apart from the "oficial" experiment, I'm experimenting with another combination, only this time there won't be a control plot. I have planted courgettes, cherry tomatoes and romaine lettuce together in about 2-3m2 (I haven't measured the bed). I wll add pumkins, onions and maybe some herbs in the adjacent bed, which is another 2-3m2. There are no more than 10 plants of anything. All is going well so far, but I'll let you know what happens in the next few months (all was planted in February indoors and transplanted about 5-6 weeks to this bed, apart from the lettuce, which I planted directly 3-4 weeks ago).
