Observation and action checklist
Clean an empty lettuce pot before the next crop
Remove the old crop and trapped debris, scrub the empty pot, then complete appropriate sanitation or choose a replacement before refilling.
Compare what you can see
The finished crop had no known root disease and the pot is sound
Empty it and remove roots, tags and lodged mix. Keep the decision about saving growing media separate from cleaning the pot. Saved mix still changes in structure and nutrients over time; it is not automatically ready for another crop.
Root disease affected the crop, or its health history is uncertain
Keep that mix and debris apart from material intended for reuse. UMD advises against saving media when root diseases were a problem. Give the pot's disease history to a local adviser when choosing sanitation; use a new suitable pot if an effective process cannot be established.
The pot is cracked, degrading, or previously held paint, cleaning chemicals or another unsuitable substance
Retire it from edible growing. Washing does not make an unsuitable container suitable. For an otherwise reusable pot, confirm that the disinfectant label permits the intended empty-container use and is compatible with the material before proceeding.
Your next care visit
Check off what you have reviewed. Use the downloadable sheet to keep your observations.
Remove the finished lettuce, loose mix and root mat. Pick remaining roots out of the rim and drain openings. Label any material being held apart because of disease concerns so it does not return to the next pot by mistake.
Use water, soap or detergent and a stiff brush to remove attached soil inside and outside. Work around the base, rim and drainage holes. Rinse away the loosened material and detergent, then inspect for hidden debris and damage.
For a suitable pot and product, follow the label's dilution, contact, rinsing, protective-equipment and disposal directions. Keep chemicals separate. If a suitable process is unavailable, mark the washed pot as awaiting a reuse decision and select a clean replacement for planting. Let the finished pot dry before clean storage.

Keep this in mind
Do not pour disinfectant into a pot containing living roots or copy one bleach dilution onto products of different strengths. Do not refill a pot while soil remains under its rim or inside its drainage openings.
What to record next
Before refilling, check the dry pot for remaining debris, damage and open drainage. Record the sanitation actually completed or the replacement chosen. After the next crop is planted, keep its observations separate; cleaning reduces transfer risk but does not guarantee disease-free growth.
- Finished lettuce pot number, material and previous contents
- Previous crop health and growing-media reuse decision
- Roots and lodged mix removed from rim and openings
- Wash and rinse completed; pot damage found
- Applicable product directions and sanitation completed, hold or replacement
- Before refilling: dry pot, clean surfaces and open drains
