What is the best month to put mulch?
Mulch can be applied anytime of the year, but you’ll see the greatest benefits if you do it in mid-spring or fall. Ideally, you would apply mulch in the spring after the soil has warmed and before weeds have emerged, but you can apply mulch anytime of the year. If you apply before the ground has thawed, it might delay your soil warming in the spring—but if winter is when you have time to apply mulch, then do it in winter.In most regions, aim for mid-to-late April, says Betz. Mulching too early can trap cold moisture and slow plant growth. Sprinkle a 2- to 3-inch layer of mulch over your garden beds and around trees, making sure not to place it too close to trunks.Problems Created by Overmulching Over-mulching can create an anaerobic (low or no oxygen) environment that allows fungal diseases to develop in plant stems and roots (some are toxic to humans). Mulching at the too early in the spring can create water logged soils that may kill drought tolerant plants.Mulching also secures a warm environment for microbes and worms to stay active underground, keeping your soil healthy through the winter. Lastly, mulch in the fall means you can skip it in the spring, giving you the bonus of working in your yard in more comfortable weather.
How much is in a bag of mulch?
The weight of a bag of mulch can vary depending on the material. On average, a 2-cubic-foot mulch bag weighs anywhere from 30-50 pounds depending on if it is wet and the type of mulch.

Wood chips cost about $85 per cubic yard, while mulch costs $30 to $150 per cubic yard. Wood chips come in larger, uniform pieces, but mulch is more thin and shredded.Mulch can mitigate soil compaction, and it is better than bare soil at capturing water and fostering water penetration, so it reduces runoff. It also slows water evaporation from the underlying soil by up to 35 percent, Dr. Fonteno said, and it moderates soil temperatures in the summer and winter.Fewer pests: Because mulch is made of wood, it tends to attract pets, some of which can wreak havoc on your house; termites, for example. Conversely, with rocks, there’s no need to worry about pests, because it doesn’t attract bugs or insects.
Does mulch prevent weeds from growing?
Weeds need light and warm soil to survive. To use mulch as a natural weed barrier, you need to put down a 2- to 3-inch layer. That’s enough to keep most weed seeds from sprouting. Because you block their access to sunlight, they won’t have enough energy to push through the mulch. After application: Water all mulched areas using a rain gauge in your beds until 1 inch (25 mm) level has been obtained. Watering will lock the mulch in place and help the finer pieces settle to the bottom for maximum weed control. Periodically monitor the soil under the mulch for moisture levels.Mulch can be applied either before or after soil preparation of new beds. Some pros prefer to mulch the entire bed free of plants ahead of time, and then make holes for the plantings, being sure to pull away excess mulch from the crowns. Others prefer to plant first and then mulch around them.In most cases, mulch is laid directly on the soil surface. For better weed suppression, spread a layer of newspaper or cardboard on the soil surface and cover with compost, bark, or other organic materials.If you are unable to clear the area of weeds it is best to put down landscape fabric before mulching.

What is the downside of mulch?
Mulch with large amounts of fines behaves like soil, so layering a soil like substance on the top of soil is soil layering, and by definition, bad. Layering soils often causes drainage problems, increases in soil type diseases, and erosion problems. However, mulching also has some potential drawbacks. For example, if too much mulch is applied, it can smother the grass and prevent it from getting the oxygen it needs to thrive.There are some species that tolerate excessive mulch better than others.
