One of the best tools that you have as gardeners to help us figure out 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 estimating when you can plant achimenes is to consult the USDA zone info for Galveston.

Planting Calendar for Achimenes

Frost tolerance for achimenes:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

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

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

Last Frost Date

The average date of last frost is February 15 in Galveston. In the coldest months of winter you should expect an average low temperature of 25°F.

Since the USDA zone info for Galveston may not be accurate from year to year the actual date of last frost can change quite a bit from year to year. Half of the time in Galveston it frosts late in the year after February 15 so always be ready to cover your achimenes in the event of a surprise late frost.
