Vancouver’s coastal climate is characterized by high humidity and frequent rainfall, which can cause issues like waterlogged soil, root rot, and mold. Managing these conditions is essential for maintaining healthy plants.

Improve Drainage to Prevent Waterlogging

Excessive moisture can cause cannabis plants to suffer from root rot, especially if the soil does not drain well. Using raised beds or planting in large containers with drainage holes helps ensure that water drains away from your plants’ roots, reducing the risk of waterlogging.

Raised Beds: Raised beds elevate plants off the ground, improving soil drainage by allowing excess water to run off more easily. This is a great option for Vancouver’s wet environment.

Soil Mix: Using a well-draining soil mix that contains materials like perlite, vermiculite, or sand can help improve drainage and prevent soil from becoming too compacted during periods of heavy rain.

Use Mulch to Retain and Regulate Moisture

Mulching is an effective way to manage moisture levels in the soil. Organic mulch, such as straw, wood chips, or compost, helps retain moisture during dry spells while preventing excess water from sitting on the soil’s surface during heavy rains. Mulch also helps regulate soil temperature by insulating roots, which is particularly important during Vancouver’s cooler nights.

Organic Mulches: Materials like straw, wood chips, or compost not only help regulate moisture and temperature but also decompose over time, enriching the soil with nutrients.

Monitor Temperature Fluctuations

Vancouver’s climate is generally mild, but temperature fluctuations, especially in early spring or late fall, can stress cannabis plants. Monitoring weather forecasts and preparing for temperature changes will help protect your plants.

Mulch for Temperature Regulation: Mulch acts as insulation, keeping soil temperatures more consistent during periods of sudden cold or heat.

Frost Protection: During early spring or fall, when frost is possible, protect your plants using row covers, cold frames, or low tunnels. These structures create a warmer microclimate around your plants and shield them from cold temperatures.
