Many homeowners revel in the glory of their garden in spring, only to be disappointed when plants start to dry out and look stressed in the heat of summer. The natural reaction is to pour more water into the garden to "moisturize" the plants. This in turn can lead to root rot and/or the continuous lowering of soil temperature to the point that plants aren't stimulated to grow--or just plain die (overwatering is one of the main causes of plant death). But these problems can be greatly reduced or, in many cases, prevented by summer mulching.

The goal of summer mulching is not only to reduce summer heat stress on plants, but to create an environment for plants that will be conducive to good growth. Mulch is to a garden what a roof is to your home. We couldn't heat or air condition the home without the roof. Summer for Fall-winter mulching is not only to reduce summer heat, but also, winter stress. A 2” layer of mulch not only retains moisture in the soil but it maintains a warmer temperature in the winter.

Mulching also brings many other benefits to the garden. It gives the garden a tidier appearance and greatly improves the growing conditions for plants. Mulch helps suppress weeds and helps to conserve moisture. It creates an environment where earthworms can thrive and enhance the soil's condition. Nature provides this for us in natural settings; when we apply mulch to our garden, we mimic what is naturally done on the forest floor.

The strategy is to stimulate the growth of good soil bacteria, which in turn digest plant foods that the plant will recognize as nutrients and absorb. By keeping moisture in the soil you will attract earthworms and beneficial microbes and bacteria. The earthworms loosen up the soil, easing compaction, while the beneficial microbes help digest nutrients more efficiently, making them more readily available to the plants. Maintaining "moist" soil as opposed to "wet" soil keeps the temperature of the soil at a more consistent level for optimum growth. Mulch also provides a blanket to the soil that protects against soil crusting, as it decomposes and adds humus to the soil.

We recommend spreading a 2" inch layer of mulch or bark over the top of the native soil. There are many mulching materials available. Color, particle size, and nutrient exchange are considerations when choosing your material. Non-organic decorative mulches such as rock or gravel may be an attractive addition in gardens but give nothing back to the soil. Note: make sure not to place mulch right up against plant stems or tree trunks.

When mulching is incorporated with a good organic fertilizing program, the plants in your garden will not only survive the stress of summer and winter, but will thrive in it. Mulch will also give your garden a more "finished" look, adding to its overall beauty.
