One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of figuring out when it's possible to plant salpiglossis is to refer to the USDA zone info for Sandy.

Planting Calendar for Salpiglossis

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

Since salpiglossis require warm weather it is important to wait until after the last frost before you can plant them.

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

The last month that you can plant salpiglossis and expect a good harvest is probably August. If you wait any later than that and your salpiglossis may not have a chance to really do well. Starting your salpiglossis indoors is a great way to get them started a couple of weeks earlier.
