One of the first steps you take when you are figuring out 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.

In Nevada you can determine when it's the best time to plant perilla by using the USDA zone info.

Planting Calendar for Perilla

Frost tolerance for perilla:	Not tolerant of frost.
When to plant:	After the last frost.

You really shouldn't plant perilla until after the last frost has passed because they require warm weather.

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

Last Frost Date

In Nevada the average date of last frost happens on April 15. It might get as low as -20°F during the coldest months of winter.

Just be sure to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Nevada and it can change quite a bit from year to year. Since half of the time in Nevada last frost occurs after April 15 be ready to protect your perilla in the event of a surprise late frost.
