One of the first steps you take when you are making a decision about 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.

In Normal you can determine when it's the best time to plant sweet woodruff by checking out the USDA zone info.

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

Sweet Woodruff do well in moderate cold which means that you can start planting them earlier than other frost tender plants.

The earliest that you can plant sweet woodruff in Normal 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 sweet woodruff and expect a good harvest is probably September. Any later than that and your sweet woodruff may not have a chance to fully mature. If you are starting your sweet woodruff indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Normal the average date of last frost happens on April 15. It might get as low as -15°F during the coldest months of winter.

Always keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Normal and it can change quite a bit from year to year. Half of the time in Normal you get surprised by a frost after April 15 so always be ready to cover your sweet woodruff if you have one of those late frosts.
