Excellent, glad to hear you're on top of the fert thing, then. So right about the pellets releasing faster in hot weather, too.
Seaweed is great, and has some added minerals but I gave up on that because it's so messy to collect and transport enough of it. The sea salt is pretty well rinsed out of it by rain before you put it on your plants.
Right again about getting so little compost from your home pile. Unless you collect grass clippings, or find someone who does, it's a challenge to make enough compost at home to be worth anything. I use mine for amending the potting soil in my outdoor pots and as a top dressing for the gingers and other heavy feeders in the ground. But when I make a new bed, or clear one out to re-plant we go to the landfill and get a load from there. It's really good stuff.
