Can I plant radish next to cucumber?

Yes. Reputed as a trap crop that draws cucumber beetles away, but the documented trap-crop research for cucumber beetles points to Blue Hubbard squash specifically, not radish. Radish IS a real, documented trap crop, but for flea beetles on brassica crops — a different pest and crop pairing than this one. Treat this specific pairing as garden tradition, not measured evidence.
