One of the first steps you take when you are determining your gardening schedule is find your 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.

A way of determining when it's possible to plant ageratum is to refer to the USDA zone info for Gainesville.

Planting Calendar for Ageratum

Frost tolerance for ageratum:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's probably a bad idea to plant ageratum until after the last frost has passed because they do not do well in cold weather.

The earliest that you can plant ageratum in Gainesville 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 ageratum and expect a good harvest is probably August. You probably don't want to wait any later than that or else your ageratum may not have a chance to fully mature. You can get started a couple of weeks earlier by starting your ageratum indoors.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Gainesville. It might get as low as 5°F during the coldest months of winter.

Always keep in mind that USDA zone info for Gainesville is not always accurate and the actual date of last frost can change quite a bit from year to year. Half of the time in Gainesville you get a frost after April 15 so make sure that you are ready to cover your ageratum if you have a late frost.
