Planting Calendar for Stocks

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

Since stocks are barely cold tolerant you can plant them just a tiny bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant stocks in Palmer 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 stocks and expect a good harvest is probably August. Any later than that and your stocks may not have a chance to really do well. If you are starting your stocks indoors then you might be able to get away with starting them a couple of weeks earlier.
