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

One way of making a decision about when to plant bellis is to examine the USDA zone info for Prosser.

Planting Calendar for Bellis

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

Since bellis do well in moderate cold you can plant them just a bit earlier in the year than other frost tender plants.

The earliest that you can plant bellis in Prosser 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 bellis and expect a good harvest is probably September. If you wait any later than that and your bellis may not have a chance to really do well. If you are starting your bellis indoors then you might be able to get away with starting them a little bit earlier.
