Nurturing nature Knowing When to Start Seedlings on Fertiliser and Nutrients Delicate seedlings need a little extra attention and knowledge to help them grow big and strong. Follow Kate Van Druff’s advice on growing conditions, nutrients, and fertiliser to get your seedlings to the next level. by Kathryn M. Van Druff Few things about gardening are as gratifying as watching a tiny seed become a flourishing plant. Flowers, herbs, fruit, vegetables, ornamentals — the possibilities of what you can grow are endless and the journey is memorable year after year. Many variables come into play as simple seeds start their lifecycles. Starting seeds indoors or outside relies on factors such as the climate and natural or artificial lighting conditions. The timing of planting also comes into play, where seedlings started indoors too early in the season and without suitable lighting can become leggy and thin rather than healthy and robust. Of course, the selected planting medium can also impact the quality of the seedlings you grow, where some potting mixes contain nutrients right from the start and others are merely, well, dirt. Finding the perfect balance of growing conditions and nutrients isn’t always easy. This article will help you to discover the best nutrients and fertilisers for your seedlings and when you should apply them. Understanding Essential Macronutrients for Seedlings Introducing fertilisers and nutrients for seedlings can boost growth and production for your plants. Plants require many different nutrients to thrive, particularly oxygen, hydrogen, carbon, which they get through water and air, as well as potassium, phosphorus, and nitrogen, which need to be added through fertilisation. These key nutrients tend to be the most important, but you’ll also want to consider micronutrients that can also fortify your seedlings for their best potential. 48 Maximum Yield
