One of the best tools that you have as gardeners to help us figure out your gardening schedule is the 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.

One way of making a decision about when you can plant rudbeckia is to examine the USDA zone info for Nederland.

When to plant:	Up to 5 weeks before last frost.

Since rudbeckia are one of those plants that can tolerate a little bit of cold weather you can plant them a little earlier in the year than plants that are more sensitive to the cold.

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

The last month that you can plant rudbeckia and expect a good harvest is probably October. Any later than that and your rudbeckia may not have a chance to grow to maturity. Starting your rudbeckia indoors is a great way to get them started a little bit earlier.
