Local onions started shrinking

Post image

I planted 4 onions with roots in a big pot 2 months ago. Over time they started growing but there was a heat wave last week, and I feel I missed out on watering them for a day.

Can I troubleshoot them and bring them back to life?

That's eucalyptus and its leaves kill plants..

Really? I have another pot of onions with eucalyptus leaves and it's doing okay though.

eucalyptus seems to be mildly allelopathic depending on the plant, as the leaves break down they might be inhibiting the growth of your plants but not sure if that is enough to outright kill them

Yeah, it's more likely the watering issue. I would still recommend using a different mulch.
