One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The best time to plant scallions in Zone 11a can be determined by reviewing the USDA zone info.

Planting Calendar for Scallions

Frost tolerance for scallions:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Scallions do ok in very little cold which tells us that you can plant them just a tiny bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant scallions in Zone 11a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant scallions and expect a good harvest is probably November. Any later than that and your scallions may not have a chance to really do well. Starting your scallions indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Zone 11a it never frosts. It might get as low as 40°F during the coldest months of winter.

Since the USDA zone info for Zone 11a is not always accurate the actual date of last frost changes from year to year. Since it never frosts in Zone 11a you do not have to be ready to protect your scallions if you have a surprise late frost.
