One of the first steps you take when you are estimating 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.

The USDA zone info for Lebanon should be looked at to determine when you can plant arctotis.

Planting Calendar for Arctotis

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

You can plant arctotis just a bit earlier in the year because they are one of those plants that can tolerate a little bit of cold weather.

The earliest that you can plant arctotis in Lebanon 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 arctotis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your arctotis may not have a chance to fully mature. If you are starting your arctotis indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

On average the last frost has passed is on April 15 in Lebanon. You can expect an average low temperature of -15°F in the coldest months of winter.

Since the USDA zone info for Lebanon may not be accurate from year to year the actual date of last frost can change quite a bit from year to year. Half of the time in Lebanon you get a frost after April 15 so make sure that you are prepared to cover your arctotis if you have one of those late frosts.
