The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of estimating when it's a good idea to plant gerbera is to check out the USDA zone info for Oregon.

Planting Calendar for Gerbera

Frost tolerance for gerbera:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

You can plant gerbera just a tiny bit earlier in the year because they do ok in moderate cold.

The earliest that you can plant gerbera in Oregon is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant gerbera and expect a good harvest is probably August. You probably don't want to wait any later than that or else your gerbera may not have a chance to really do well. You can get started a few weeks earlier by starting your gerbera indoors.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in Oregon. You can expect an average low temperature of -20°F in the coldest months of winter.

Since the USDA zone info for Oregon is not always accurate the actual date of last frost is different every year. Since half of the time in Oregon last frost occurs after April 15 be ready to protect your gerbera in the event of one of those late frosts.
