Germinating dried guava seed
« on: October 10, 2022, 01:48:58 AM »
I purchased a few dried guava seed and successfully germinated them in some damp vermiculate (they put out a small root), but now they all have a hard-as-rock helmet head on the seedling. Is this fixable, or is this normal?

I have had this problem with some seeds, and I take a pair of needle nose pliers and very carefully squueze the seed helmet until it splits.  Then I just leave it and the seedling is usually able to get the cotyledons out of the seed once it is split.

Sometimes happens with Citrus. The seed coat dries out while germinating. Can be a problem to remove without damaging the cotyledons. Usually wait until it splits a bit more.
Maybe increasing humidity will help, but watch for damping off.
