I've always loved gardening as well, ever since I was about 10-11 or so. There's something about it that feels more real that other stuff. And I like being able to make things grow, to work on projects, design planting schemes, create fresh produce or flowers, and encourage insects and wildlife etc.
Speaking of designing stuff, I've really been getting into sub-irrigation systems (self-watering) lately. They all self-water from reservoirs I built beneath them, and the water is carried up via wicking strips. The reason it's called self-watering is because as plant roots draw up moisture from the soil, it encourages the wick to draw up more water. So it never gets either too saturated or too dry, and the soil is able to maintain a comparatively stable moisture and nutrient content no matter how greedy the plants get. Which is especially good for, say, heavy flowering annuals and particularly vegetables
Here's a few snaps of some projects I've recently finished:
