I've been working on trying to show one of my neighbors how to start seeds for their garden and the difference between just the peat pellet and good compost. Both these seedlings sprouted at the same time. The difference is the big one was put into the compost soil, peat pellet and all, right after it sprouted and the other was just left to grow on it's own. These seedlings are 2 weeks old, both large red cherry tomatoes. Both are growing on the same shelf in the window, right next to each other. I didn't even sift the compost, I just scooped some into the container.
These tomatoes will be my indoor plants for this winter.
There's nothing particularly special about the compost, it's just horse manure, hay, straw, a little sawdust, some rabbit, goat, chicken and a little cow manure in there too. Mostly horse manure tho. I don't turn the pile over, it's just occasionally heaped up with the latest additions which tend to end up spread out around the main pile.
The secret to strong plants and a successful garden is the soil. The more organic material you can get, the better. Plants need nutrients to thrive. Water alone will not do the trick. Commercial potting soils have a limited amount of nutrient available in them and it quickly runs out. Adding a good organic compost to your garden will ensure that your plants achieve maximum potential.
