One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of getting a good idea when you can plant salpiglossis is to refer to the USDA zone info for Seaside.

Planting Calendar for Salpiglossis

Frost tolerance for salpiglossis:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Since salpiglossis do not do well in cold weather it's necessary to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant salpiglossis in Seaside is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant salpiglossis and expect a good harvest is probably September. Any later than that and your salpiglossis may not have a chance to grow to maturity. You can get started a little bit earlier by starting your salpiglossis indoors.

Last Frost Date

In Seaside the average date of last frost happens on February 15. In the coldest months of winter you can expect an average low temperature of 20°F.

Since the USDA zone info for Seaside may not be accurate from year to year the actual date of last frost changes from year to year. Half of the time in Seaside you get a frost after February 15 so always be ready to cover your salpiglossis if you have a late frost.
