While building and maintaining balanced soils remains essential for plant nutrition, foliar feeding has emerged as a supplemental technique for supplying nutrients directly to plants. By applying foliar fertilizers through sprayer applications, nutrients and enzymes are absorbed through the pores of the plant leaves. In this blog post, we will explore the practice of foliar feeding cannabis, its benefits, and our preferred approach to implementing it on our farm. Although it is not a substitute for proper soil management, foliar feeding serves as a valuable tool for supporting stressed or rapidly growing plants.
What is Foliar Feeding and What is Its Role?
Fast-growing annuals, such as many crops found in the agriculture industry, require substantial amounts of essential nutrients like nitrogen, phosphorus, and potassium. While foliar feedings alone cannot fulfill these requirements, our experience has shown that plants in stress or experiencing rapid growth can benefit significantly from this technique. Foliar feeding acts as a rapid supply of micronutrients, including iron and zinc, which are crucial for plant health but may have limited availability in the soil. By employing foliar feedings, we can provide targeted nutrition to enhance the overall vigor and resilience of plants.
When and Which Plants to Focus On
In our farming practices, we emphasize foliar feeding cannabis during two key phases: plant propagation and the first month after transplant. These stages are critical for establishing healthy root systems and fostering optimal growth. By investing in foliar fertilizers and foliar feedings during this period, we can promote stronger plant development and maximize nutrient uptake.
Our Preferred Products for Foliar Feeding
When it comes to choosing the right foliar feedings for our crops, we integrate a selection of proven products. These include:
- Homemade Compost Tea:
Compost tea, crafted from high-quality compost material and brewed to extract beneficial microorganisms, serves as a holistic approach to foliar feeding. This organic mixture not only supplies essential nutrients but also introduces beneficial microbial communities that contribute to soil health. - Calcium:
Calcium plays a vital role in cell development and strength. Foliar application of calcium can effectively address deficiencies or provide additional support during stressful periods for plants. - Nitrogen:
Nitrogen is crucial for promoting leafy growth and overall plant vigor. Foliar feeding with nitrogen-rich products can provide a much-needed boost during periods of rapid growth or when plants show signs of nutrient deficiency. - Kelp Extract:
Kelp extract is a valuable source of micronutrients and growth stimulants. It contains trace elements that may be limited in availability within the soil and can enhance plant resilience to stress, ultimately leading to improved yields.
Ensuring Success with Foliar Feeding
While foliar feeding cannabis offers numerous benefits, it is essential to follow some best practices to achieve the desired outcomes. Here are a few key tips:
- Timing is key: Apply foliar feedings during mild weather conditions, ideally early in the morning or late in the afternoon, to avoid leaf burn and optimize nutrient absorption.
- Dilution is crucial: Ensure proper dilution of foliar feedings according to the product instructions to prevent over-application and potential plant damage.
- Consistency matters: Incorporate foliar feedings into a comprehensive plant nutrition plan, considering soil health and regular fertilization practices. Foliar feeding should be an additional tool, not a replacement for proper soil management.
Foliar fertilizers and foliar feeding serves as a valuable technique to supplement plant nutrition and support the health and vitality of crops. While it cannot replace building and balancing healthy soils, foliar feeding proves especially beneficial for stressed or rapidly growing plants. By focusing on plant propagation and the initial transplant phase, and applying key products like homemade compost tea, calcium, nitrogen, and kelp extract, growers can harness the power of foliar feeding to optimize plant development and overall performance. By integrating this practice into a holistic approach to plant nutrition, farmers can achieve healthier and more abundant harvests.
