Which conditions can hold back an onion crop?

Check whether the planter provides suitable root room, whether the soil matches the plant’s needs, and whether the crop has suitable water, light, and temperature while remaining free of weeds. Inadequate temperature control is specifically associated with very slow onion growth.

What should I check before changing the setup?

Start with ALT and the Guide, then follow the requirements displayed while filling the pot instead of guessing. After the soil check, inspect water and weeds, then use placement or light-control equipment and heating or air conditioning where the reported conditions require changes.

Diagnose slow onion growth

Poor temperature control can make onions grow extremely slowly: one documented player example spanned multiple in-game months. Onion growth also depends on a suitable planter and root space, the preferred soil conditions, water, weed removal, light, and temperature.

Press ALT to inspect the plant status and match its symbols in the Guide. Check the pot’s displayed soil requirements against the amount of each material already added, then correct water or weed problems. Adjust light through placement, shading nets, or grow lights, and adjust temperature with heaters or air conditioners.
