The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of figuring out when it's possible to plant santolina is to consult the USDA zone info for Edinburgh.

Planting Calendar for Santolina

Frost tolerance for santolina:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Santolina tend to make it in pretty solid cold which means that you can plant them a lot earlier in the year than more sensitive plants.

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

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

Last Frost Date

In Edinburgh the average date of last frost happens on April 15. You should expect an average low temperature of -10°F in the coldest months of winter.

Remember that the actual date of last frost is just an average because it is based on the USDA zone info for Edinburgh and it can change quite a bit from year to year. Half of the time in Edinburgh you get surprised by a frost after April 15 so just be sure to be ready to cover your santolina if you have a surprise late frost.
