Wine Caps can be expanded indoors anytime, for future planting outdoors. Planting outdoors depends on where you are located in Canada. Here on Vancouver Island, Wine Caps can start growing from March onwards. Other parts of Canada you might want to wait until April or May. Wine Caps can survive cold weather, they just won’t grow very well until things warm up. Check the last frost dates for your region to get a better idea of when to start your Wine Caps.
