One of the best tools that you have as gardeners to help us determine your gardening schedule is the 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 Aberdeen you can estimate when it's a good idea to plant gladiolus by checking out the USDA zone info.

Planting Calendar for Gladiolus

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

Gladiolus can survive in a tiny bit of cold which tells us that you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant gladiolus in Aberdeen 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 gladiolus and expect a good harvest is probably September. Any later than that and your gladiolus may not have a chance to really do well. Starting your gladiolus indoors is a great way to get them started a little bit earlier.

Last Frost Date

Since the USDA zone info for Aberdeen is just an average the actual date of last frost is different every year. Half of the time in Aberdeen there is a last frost after February 15 so make sure that you are ready to cover your gladiolus in the event of one of those late frosts.
