Tea Leaves
Save your tea leaves to put out as a mulch on the garden. Wet or dried, they will provide nutrients to trickle down. In the flower garden particularly, Camellias will benefit from tea leaves.
Milk
When milk cartons or jugs are finished, they should be rinsed with a cup of water and the contents spread on the garden. A little bit of nutrients added in a frequent watering will go a long way.
Banana Skins
Banana skins should be laid just below the surface of the soil around the base of rose plants, as they are known to benefit the roses by releasing a considerable quantity of calcium, magnesium, sulfur, phosphates and silica.
Beer
Like the milk, rinse beer bottles with water and toss the contents out on the kitchen garden. The yeast in the liquid will do wonders for your nearby plants.
Old Boots
Never toss your worn out soles into the garbage; real leather is full of good things for your soil. Toss them in the compost instead. The leather will rot down eventually and the rubber parts can be retrieved easily afterwards.
