One of the first steps you take when you are making a decision about your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of getting a good idea when to plant pyrethrum is to look at the USDA zone info for Eden.

Planting Calendar for Pyrethrum

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

You can plant pyrethrum a little bit earlier in the year because they do well in moderate cold.

The earliest that you can plant pyrethrum in Eden 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 pyrethrum and expect a good harvest is probably September. You probably don't want to wait any later than that or else your pyrethrum may not have a chance to fully mature. Starting your pyrethrum indoors is a great way to get them started a few weeks earlier.

Last Frost Date

On average the last frost is on April 15 in Eden. You should expect an average low temperature of 5°F in the coldest months of winter.

Since the USDA zone info for Eden is not always accurate the actual date of last frost can change quite a bit from year to year. Since half of the time in Eden last frost occurs after April 15 be ready to cover your pyrethrum in the event of one of those late frosts.
