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.

One way of making a decision about when you can plant roses is to consult the USDA zone info for Centralia.

Since roses 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 other plants that might not handle the cold.

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