The earliest that you can plant hosta in Lebanon 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 hosta and expect a good harvest is probably September. If you wait any later than that and your hosta may not have a chance to grow to maturity. Starting your hosta indoors is a great way to get them started a couple of weeks earlier.
