Many homeowners take great delight in the beauty of their gardens during springtime, only to experience disappointment when their cherished plants begin to wither and appear distressed in the sweltering heat of summer. The typical response is to increase watering in an attempt to “hydrate” the plants. However, this well-intentioned act often leads to problems such as root rot and a continuous drop in soil temperature, hindering plant growth or even causing their demise. Overwatering stands as one of the leading causes of plant fatalities. Fortunately, these issues can be significantly mitigated through the proper practice of mulching.
The primary objective of mulching is not merely to shield plants from the harsh heat of summer but to establish a nurturing environment that promotes robust growth. Think of mulch as the roof for your garden, akin to the protective cover over your home. Without a roof, we would be unable to control the temperature inside our homes, and the same temperature fluctuations affect your garden throughout the year. A 3-inch layer of mulch not only traps moisture in the soil but also regulates temperature, keeping it cooler during summer and warmer during winter.
Mulching offers a multitude of advantages for your garden. Mulch serves as a natural weed suppressor and aids in moisture conservation. It creates an environment conducive to the thriving of earthworms, which, in turn, improve soil quality. Organic mulches break down over time, enriching the soil with humus. Nature provides this ecosystem service in natural settings, and when we apply mulch to our garden, we emulate what occurs naturally on the forest floor. In addition to the numerous horticultural benefits that mulching provides, it imparts a polished and “finished” look to your garden, enhancing its overall aesthetic appeal.
The technique involves spreading a 2-3-inch layer of composted mulch over the native soil before the peak of summer heat arrives. Various mulching materials are available, each with considerations like color, particle size, and nutrient exchange. While decorative barks may be visually appealing, they can deplete nitrogen from the soil. If opting for decorative bark, it is advisable to layer it over composted mulch to balance out nutrient loss.
