When staining your deck, be careful not to apply too much of the stain. You don't want to get surface film on the wood when what you're really going for is penetration. Also, be sure to keep a wet edge so you don't get unsightly lap marks. Apply stain in the proper weather conditions. Avoid applying the product in direct sunlight, and be sure there is no chance of rain for the next 24 hours.
The microorganisms in the compost pile function best when the materials are as damp as a wrung-out sponge and have many air passages. Extremes of sun or rain can adversely affect the balance of air and moisture in your pile. The air in the pile is usually used up faster than the moisture, so the materials must be turned or mixed up occasionallly to add air that will sustain high temperatures and control odor. Materials can be turned with a pitchfork, rake, or other garden tool.
