Before planting it is a good idea to find your USDA Zone info to figure out your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of estimating when you can plant rudbeckia is to use the USDA zone info for Rincon.

Planting Calendar for Rudbeckia

Frost tolerance for rudbeckia:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since rudbeckia do well in moderate cold you can plant them a bit earlier in the year than more sensitive plants.

The earliest that you can plant rudbeckia in Rincon 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 rudbeckia and expect a good harvest is probably September. You probably don't want to wait any later than that or else your rudbeckia may not have a chance to grow to maturity. You can get started a little bit earlier by starting your rudbeckia indoors.

Last Frost Date

The average date of last frost is March 15 in Rincon. It might get as low as 15°F during the coldest months of winter.

Keep in mind that the actual date of last frost is not always accurate because it is based on the USDA zone info for Rincon and it is different every year. Half of the time in Rincon there is a last frost after March 15 so make sure that you are ready to cover your rudbeckia in the event of one of those late frosts.
