How can I improve soil health for my dianthus in a permaculture setup?
I'm currently designing an edible landscape that incorporates dianthus, and since I focus on permaculture principles, I'm concerned about soil health. My garden is located in a temperate zone with clay-heavy soil that I've been amending with compost and organic matter. I've tried incorporating cover crops and mulching to improve soil structure, but I'm not seeing the results I want in terms of dianthus growth. My specific problem is that some of the plants seem stunted, and I suspect it’s related to the soil's nutrient balance. Can anyone provide insights on specific soil amendments or practices that will enhance soil health for my dianthus and promote a thriving ecosystem?
