Outdoor cannabis cultivation offers a number of advantages over indoor growing, including lower costs, simpler set-ups, and easier maintenance. However, one of the most important considerations for outdoor growers is timing: when to plant your cannabis seeds outdoors.

In this article, we’ll give you a general timeline for when to plant your cannabis seeds outdoors in various parts of the world. Of course, these are only guidelines – your actual timing may need to be adjusted based on your specific location and weather conditions.

As a general rule of thumb, you should wait until at least late April/early May to plant your cannabis seeds outdoors in most parts of the United States and Canada. In more southern regions (such as California), you can actually get away with planting a little earlier, around mid-April. However, if you live in a more northern region (such as Oregon or Washington), you may want to wait until late May or even early June to plant your seeds.

Remember, the key is to wait until both the day and night time temperatures are consistently above 50°F (10°C). If it gets too cold at night, your plants will suffer – and if it gets too hot during the day, they will also suffer. So err on the side of caution and wait until things have warmed up before planting your outdoor cannabis crop.

The Best Time to Plant

The best time to plant cannabis outdoors is in the late spring or early summer. This ensures that the plants will have enough time to grow and mature before the first frost of winter. In general, it is best to plant cannabis seeds about 1-2 weeks before the last expected frost date in your area. This gives the plants time to establish a strong root system before they begin their vegetative growth.

Cannabis plants need a minimum of 6 hours of direct sunlight per day to grow healthy and produce buds. If you live in an area with long summer days, your plants will likely get more than 12 hours of sunlight per day. In this case, it is best to plant cannabis seeds in mid-spring so that the plants have time to grow and mature before the days become too long.

If you live in an area with shorter summer days, you may want to consider planting cannabis seeds a bit later in the season. This will help ensure that your plants do not get too much sunlight and produce too many thin, airy buds.

The Worst Time to Plant

The Worst Time to Plant Outdoor Cannabis

You might think that the worst time to plant outdoor cannabis is in the middle of winter. After all, it’s cold outside and the plants will have a hard time surviving. However, the worst time to plant outdoor cannabis is actually in the spring.

Why is spring the worst time to plant outdoor cannabis? There are two reasons. First, the soil is still too cold for the plants to properly root. If you plant too early, the plants will struggle to take root and they won’t be able to grow properly. Second, there is a risk of frost damage if you plant too early in the spring. The plants could be damaged or even killed by a late frost, which would ruin your entire crop.

So when is the best time to plant outdoor cannabis? The best time to plant is actually in late spring or early summer, after the risk of frost has passed. This way, the soil will be warm enough for the roots to take hold and the plants will have plenty of time to grow before winter arrives.

Planting in Late Spring

Planting in late spring, after the last frost date, is ideal for most cannabis strains. By planting your cannabis after the last frost date, you can be sure that your plants will not be damaged by frost or cold weather. Late spring is also a good time to plant because it gives the plants a chance to grow and establish themselves before the hot summer weather arrives.

Planting in Early Summer

The best time to plant your cannabis outdoors is in early summer. This gives the plants enough warm weather to grow and develop properly, but it also means that they will be ready to harvest before the end of summer.

You should start by preparing your planting area. Use a soil mix that is designed for cannabis, and make sure it is well aerated. You can also add some organic matter to the soil, such as compost or manure, to help the plants grow.

Once the planting area is prepared, you can sow the seeds or transplant the seedlings into the soil. Be sure to space them out so that they have plenty of room to grow.

Water the plants regularly, and fertilize them every few weeks with a liquid plant food. If you live in an area with a lot of rain, you may need to water less often.

In late summer, you can begin to harvest your plants. Start with the smaller ones first, and then work your way up to the larger ones. Make sure to dry and cure the buds properly before storing them.

Planting in Late Summer

For most of us in the Northern Hemisphere, late summer is the time to start planting our outdoor cannabis gardens. The key to a successful harvest is to give your plants enough time to fully mature before the first frost of fall. In general, you should start planting around the end of August or early September, depending on your location.

If you live in a climate with a short growing season, you may want to start your plants indoors and then transplant them outdoors when the weather is warm enough. This will give them a head start on the growing season and increase your chances of a successful harvest.

When choosing a location for your garden, make sure it gets plenty of sunlight and has well-drained soil. Cannabis plants do best in sandy loam soils with a pH between 6.0 and 7.0. If you’re not sure about the quality of your soil, it’s always a good idea to have it tested by a professional before you plant anything.

Once you’ve selected a location and prepared the soil, it’s time to choose your plants. If you’re growing from seed, be sure to select a variety that is suited for outdoor cultivation in your climate zone. For example, if you live in an area with a short growing season, choose a variety that matures quickly such as Northern Lights or White Widow. If you live in an area with long hot summers, choose a sativa variety such as Haze or Skunk #1 that can handle the heat and produce bountiful harvests.

Once you have your plants, it’s important to harden them off before transplanting them into their final location outdoors. This process acclimates them to their new environment and helps reduce transplant shock. To harden off your plants, start by placing them outdoors in a sheltered spot out of direct sunlight for an hour or two each day. Gradually increase the amount of time they spend outdoors over the course of 7-10 days until they are able to tolerate being outside all day long without any problems.

Once your plants are acclimated to their new environment, it’s time to transplant them into the garden and start looking forward to a bountiful harvest!

Planting in Early Fall

In many parts of the world, the outdoor cannabis planting season begins in late spring and extends through early summer. In cooler climates, it may be necessary to wait until mid-summer for the soil to warm up enough for successful germination.

In warm climates, it is possible to plant as late as early fall and still expect a good harvest. This is because the days are shorter in fall, which means the plant will begin to flower sooner. Outdoor growers in very warm climates (zone 11) can even plant in late fall and early winter, although they may not get as large of a harvest.

Planting in Late Fall

Fall is an excellent time to plant cannabis. The weather is cooling down, so the plants won’t be under as much stress, and the days are still long enough for the plants to get plenty of sunlight.

However, there are a few things to keep in mind when planting in late fall. First, make sure that you live in an area where the winters aren’t too harsh. Cannabis plants can withstand cold temperatures, but if the winters are too severe, they may not survive.

Second, make sure that you plant your cannabis plants in an area that gets plenty of sunlight. Cannabis plants need at least six hours of sunlight per day to thrive.

Finally, make sure to water your plants regularly. The cooler weather in fall can make it easy to forget to water your plants, but they still need to be watered regularly to stay healthy.

If you keep these things in mind, planting cannabis in late fall can be a great way to get a head start on the next growing season.


As you can see, there is a lot of variation in when to plant your outdoor cannabis crop. Ultimately, it is best to start with smaller plants in early spring and then transplant them into their final location after the last frost date for your area. This will give your plants the best chance to thrive and produce a bountiful harvest.
