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 Athens you can estimate when to plant nasturtium by using the USDA zone info.

Planting Calendar for Nasturtium

Frost tolerance for nasturtium:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's probably not a good idea to plant nasturtium until after all chance of frost has passed because they are not cold tolerant.

The earliest that you can plant nasturtium in Athens is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant nasturtium and expect a good harvest is probably August. Any later than that and your nasturtium may not have a chance to grow to maturity. If you are starting your nasturtium indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

The average date of last frost is March 15 in Athens. It might get as low as 10°F during the coldest months of winter.

Remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Athens and it is different every year. Half of the time in Athens last frost occurs after March 15 so make sure that you are prepared to cover your nasturtium if you have a surprise late frost.
