Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

You can figure out when to plant hosta in Vancouver by looking at the USDA zone info.

Planting Calendar for Hosta

Frost tolerance for hosta:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Hosta tend to make it in a little bit of cold which tells us that you can plant them just a bit earlier in the year than more sensitive plants.

The earliest that you can plant hosta in Vancouver 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 fully mature. You can get started a few weeks earlier by starting your hosta indoors.

Last Frost Date

The average date of last frost is March 15 in Vancouver. In the coldest months of winter you should expect an average low temperature of 15°F.

Since the USDA zone info for Vancouver is not always accurate the actual date of last frost changes from year to year. Half of the time in Vancouver you get surprised by a frost after March 15 so make sure that you are prepared to cover your hosta if you have one of those late frosts.
