Cucumbers uses a reviewed indoor transplant start profile instead of the former universal six-week default. The local frost date remains editable because cultivar, soil, hardening and microclimate can move the plan.
Cucumbers profile
Cucumbers uses a reviewed indoor transplant start profile instead of the former universal six-week default. The local frost date remains editable because cultivar, soil, hardening and microclimate can move the plan.
- Reference method: indoor transplant start; published lead-time reference: 3–4 weeks.
- Use a short indoor lead because overgrown cucurbits can transplant poorly.
Work backward from your local last-frost date by the crop's reviewed indoor-start lead time.
Context matters.
- Cultivar, transplant tolerance, germination temperature, hardening and local microclimates can shift the planting window.
