When should I plant for crossbreeding in Rust?

Plant the one you're breeding first, then the plants around it about halfway through its Sapling stage: roughly 16 minutes later, or 9 if it has 3 G. It crosses as it enters the Crossbreed stage, using whatever touches it at that moment: about 21 minutes after planting, or 12 with 3 G, and later if it lacks fertilizer, light or water.

The timeline

Crossbreeding timeline
0 minPlant the bred plant alone, for a head start.
Mid-SaplingPlant the donors around it (any labelled 1st, 2nd first): about 16 min in, or 9 if the bred plant has 3 G. They count even as seeds.
CrossbreedThe bred plant crosses: about 21 min in, or 12 with 3 G, later in poor conditions. Keep every donor alive and in place until it's past Crossbreed.
MatureCheck the genes and clone it.

Why the head start?

Donors cross too when they reach Crossbreed. If one gets there before the bred plant, the bred plant sees the donor's new genes instead of the ones you planned for.

Another way: use donors that are already Mature or later. They've finished crossing, so their genes won't change.

Where to put them

  • Same planter, same plant type. Planters pushed together never cross, and hemp only listens to hemp.
  • Touching the bred plant, diagonals included. In a Large Planter Box, breed in the middle so eight donors can reach it. Other planters
  • Planting order decides a tie between two genes in a slot. Ties and planting order
