One way of figuring out when to plant calibrachoa is to look at the USDA zone info for Oxford.

Planting Calendar for Calibrachoa

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

Since calibrachoa do ok in moderate cold you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant calibrachoa in Oxford 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 calibrachoa and expect a good harvest is probably August. You probably don't want to wait any later than that or else your calibrachoa may not have a chance to fully mature. If you are starting your calibrachoa indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

Just be sure to remember that the actual date of last frost is an average because it is based on the USDA zone info for Oxford and it changes from year to year.
