Observation and action checklist
Clear a radish container before its next sowing
Finish the old batch, remove competing roots and decide whether another spring-radish sowing still fits the conditions.
Compare what you can see
Usable radishes or smaller plants are still growing in the intended space
Choose whether to finish that batch now or keep it longer. Leave the next sowing unsown until its allocated space is cleared; adding seeds around standing roots does not create a fresh batch.
The packet identifies spring radishes but the next growing period is likely to be hot
Skip the repeat and retain the seed for a locally suitable cool-season window. Do not use the first batch's success as evidence that the next batch will experience the same conditions.
The old batch is removed and another sowing is locally suitable
Inspect the mix and drainage, then lay out a new, labeled batch. If the previous crop had unresolved root decay or unexplained collapse, pause reuse and seek identification rather than treating this routine restart as sanitation.
Your next care visit
Check off what you have reviewed. Use the downloadable sheet to keep your observations.
Lift the remaining plants you have chosen to finish. Count usable roots separately from discarded plants, and remove stems and substantial root remnants from the new seed positions. Record the clearing date instead of copying an earlier planned harvest date.
Loosen the surface of suitable, moist potting mix and check that water can leave the container. Remove remaining plant debris instead of immediately burying it beneath seed. UMN warns that leftover stems and roots can interfere with germination; do not assume undecomposed material has become finished compost.
Follow the variety's packet. UMD's general radish reference places seeds one to two inches apart and a quarter to half an inch deep, followed by thinning to the type's final spacing. Mark the positions, cover lightly, water gently and give this batch a new date and seed count.

Keep this in mind
Do not automatically add nitrogen to a restart; excess nitrogen can favor leaves over roots. Do not count the cleared batch and its replacement as simultaneous harvests or assume every radish type matures on the same timetable.
What to record next
Check moisture and emergence in the newly labeled area. Once seedlings can be assessed, thin to the packet's final spacing; UMD gives a general two-to-four-inch range depending on type. Start sampling roots at the cultivar's harvest stage rather than waiting for maximum size, and recheck seasonal suitability before planning any further repeat.
