Two for the space of one!

I haven't consciously tried this, for one, the only long staying plant I grow is kale. I have, as I expect everyone does, filled in gaps in my inevitable rows by anything that's available. I tried my version of three sisters with squash traipsing underneath sweetcorn, but it wasn't successful. I far i m8ght have kept the normal planting distances and therefore everything was well crowded and starved of light. I think perhaps in order, maybe erroneously, to get the most out of the space I have, I tend to cram plants too close together, so putting anything extra would be a disaster. An example, I sowed some carrots in tubs to over winter, they grew slowly and are now less than pencil thick, probably because they're sown too thickly. You would think after all these years I would have learnt nothing I try to over winter works very well.

I did sow sweetpeas to grow up the trellis outside the gh and used the same patch to grow toms, using the trellis for support, that has worked quite well for several years.
