The purpose of the bag is to keep the plant above freezing on the cool nights IT gets the plant in the ground early BUT often the harvest is not earler...... I move the plants to a larger container & continue to grow inside untill the weather permits setting out. this way my plants are usually larger & give a early harvest.

Thank you for your reply. I have some daylily seedlings I want to transplant up but will not be planting in the ground until later in the season.

So these are not recommended for outdoor use at all?

Best Regards,

Please clarify what you mean by "poly grow bags"??? Are you meaning "containers" made out of thin poly.???? (I ask because the first reply led me to believe you were asking about the top of the plant, not the roots).

I meant to ask if anyone has ever used these grow bags as temporary containers in an outdoor environment.

I have seedlings I wish to transplant into them until later in the season when I can plant them in their permanent homes in the ground.

Frost/freezing is not the issue for me.

Thank you.
