When to plant:	After all chance of frost has passed.

You can not plant alternaria until after all chance of frost has passed because they do not do well in cold weather.

The earliest that you can plant alternaria in Pacifica 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 alternaria and expect a good harvest is probably September. You probably don't want to wait any later than that or else your alternaria may not have a chance to fully mature. If you are starting your alternaria indoors then you might be able to get away with starting them a little bit earlier.
