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.

You can determine when it's possible to plant morning glory in Zone 9a by reviewing the USDA zone info.

Planting Calendar for Morning Glory

Frost tolerance for morning glory:	Not tolerant of frost.

Since morning glory do not do well in cold weather you really should wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant morning glory in Zone 9a 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 morning glory and expect a good harvest is probably September. If you wait any later than that and your morning glory may not have a chance to really do well. If you are starting your morning glory indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is February 15 in Zone 9a. It might get as low as 20°F during the coldest months of winter.

Since the USDA zone info for Zone 9a is not always accurate the actual date of last frost will vary from year to year. Half of the time in Zone 9a it frosts late in the year after February 15 so always be ready to cover your morning glory if you have one of those late frosts.
