Naturalizing cannabis in Canada

Can marijuana be naturalized in Canada? If I plant a couple of plants in an outdoor location and come back in a couple of years will there be many plants?

Marijuana can naturalize in Canada. It may take quite a few plants to find ones that will flower and develop mature seeds before they are killed by the cold weather.

Start with early season outdoor or fast maturing indoor varieties. Plant the seedlings or seeds with enough space for the plants to grow out, but close enough so that males will be able to pollinate the flowers. You are looking for a plant that is especially well adapted to your area and is able to complete its cycle before frost.

The earlier the seeds mature, the more likely they are to drop from the plant and be covered with debris. This protects them from the elements and enables them to survive the winter. They will germinate in the spring.

The critical step is finding plants that mature early enough to produce viable seeds. If no viable seeds are produced, the plants have no chance of naturalizing. If only a few are produced, collect them for planting next year. These seeds are likely to mature early.

When the plants yield prodigious quantities of seed that fall to the ground, the plants are probably naturalized. Only a small percentage of the seeds will geminate, but the resulting plants will fill the area.
