One of the best tools that you have as gardeners to help us determine 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.

In Wellington you can estimate when it's possible to plant salpiglossis by reviewing the USDA zone info.

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

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 few weeks earlier by starting your salpiglossis indoors.
