Potatos do well in cold weather which tells us that you can plant them quite a bit earlier in the year than more sensitive plants.

The earliest that you can plant potatos in Peru 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 potatos and expect a good harvest is probably September. If you wait any later than that and your potatos may not have a chance to fully mature. If you are starting your potatos indoors then you might be able to get away with starting them a little bit earlier.
