To water newly planted trees and shrubs, take a 5-gallon bucket and drill a 1/8" hole near the bottom. Fill the bucket with water (preferably rainwater) and it will slowly water the soil around the tree, soaking in deeply, which is just what the plant wants.
During the winter bury your coffee grounds and other compostable material directly in your garden. Come spring it will have decayed into a nice black planting spot full of worms.
Don't rake the leaves from your flower beds in the fall. Leave them until spring. They will help insulate your plants and decompose to enrich your soil.
When photographing your garden or plants, do it on a cloudy day. The light is more even and diffused.
