If they look like little pieces of dried cork and their tunics are loose around the actual bulb, it's probably not worth trying.

If they are still plump then it's worth putting them in. In zone 9 you can probably leave them in the ground all year, only thinning them out when they become overcrowded.

A sandy sort of soil that gets at least half a day's sunlight and reliable winter water will give you a good chance of success with your Freesias.

How long will they last? If they get too shrivelled then even a few months is too long. And if they start to sprout but aren't planted then they rapidly run out of the ability to grow/flower. For many bulbs, four to six months - fewer if they have not been hardened off or have had their leaves removed too soon.

The main reasons for lifting bulbs are:
they've become overcrowded; you want to share with someone; you need the space for something else and don't want to put the spade through them; or the climate has extremes that the bulbs can't tolerate.
