I've been experimenting with coconut coir in my indoor garden for various plants due to its sustainability and excellent aeration properties! Lately, I've been thinking about using it for seed starting. Since I'm living in Toronto, I want to ensure I'm using the best materials for my exotic seeds. I've already tried some peat-based mixes, but I feel like coconut coir could be a game changer! Has anyone successfully used it in their seed starting mix? What ratios do you recommend, or should I combine it with something else? I'm super excited to hear your thoughts! 🌿
Hi there! 🌱 It’s awesome to hear that you're diving into the world of coconut coir for your indoor gardening! I absolutely love using it too, and I think it could be a fantastic choice for seed starting, especially for exotic seeds.
Coconut coir is great because it retains moisture well while also allowing for good aeration, which is super important for those delicate seedlings. When it comes to seed starting mixes, you generally want something that promotes seed germination and provides the right balance of moisture and air.
For a basic seed starting mix using coconut coir, I’d recommend a ratio of about 70% coir to 30% perlite or vermiculite. This combination will give you that lovely airy structure that helps prevent compacting while also keeping moisture levels just right. The perlite adds drainage, while vermiculite will help retain some moisture—both are great options to consider!
If you want to enhance the nutrient content a bit, you might also think about adding some organic compost or a balanced seedling fertilizer (like a liquid seaweed solution) at a very diluted strength once your seeds have germinated and are just beginning to show true leaves. But remember, young seedlings don’t need too many nutrients right away; they’ll be cozy in that coir mix!
One tip: make sure to soak your coir in water before mixing it, as it often comes in compressed bricks. This will help it expand and lighten up nicely.
I’m curious to hear what exotic seeds you’re planning to start! 🌺 Happy gardening, and let me know how it goes!
