Seeds that don’t sprout

Hi

I m in zone 7b. I started all sorts of palm seeds including some zone 10.

I sow them directly in pots with mix.

The seedlings go under lights during the cold months.

Can i put the pots with the ones that have no sprouted in my unheated garage (Low 30’s at worst)?

If yes do i have to drag the pots out like my other palms/Seedlings on nice days?

Or do i have to keep the un sprouted pots warm and under grow lights?

Thxs

I wouldn't try that with zone 10 palms - they are quite tropical. With cold hardier species the seeds may survive but don't expect them to germinate until spring warm up. My experience here in FL is that no palm seeds germinate even in my more benign winter. Could be cooler weather or shorter days - I don't know.

Let the sleeping seeds lye. They will not sprout until they feel a period of warmth. They will ignore a couple warm days in the sun,and you would just be wasting your time moving them. If you bring them inside your house with warmer temps in February,you may be able to gain a month or two by tricking them into sprouting.

Good advice given.  Some palm seeds have longer shelf-life than others.  Tropical species typically have shorter windows of viability while desert species such as Phoenix dactylifera, Washingtonia and Brahea species are usually viable for years.  Obtaining fresh seeds is important generally speaking however.

I recently had Chamaerops seeds sit in a community pot for about a year and didn't sprout so I reused the soil to plant something else since they typically sprout in just a few months.  Somehow the original seeds came to life and germinated!  As long as the seeds are solid there's still hope for them so don't give up too quickly.

I agree with what you wrote.

i started various seeds in the backyard. I sowed them and left them on their own.

Most came out but not the C. humilis and Nannorrhops ritchiana.

The Nannorrhops ritchiana never came out but 2 years later several C. humilis emerged.
