retains moisture - a 2-3 " layer of mulch protects the soil surface from sun and wind which contribute to evaporation. Garden beds require less water when mulched which is eco-friendly and lower maintenance.
insulates - mulch acts as an insulator for your garden from both heat and cold. Soil temperature is moderated placing less stress on the root system resulting in healthier plants.
blocks weeds - when weeds are covered by mulch, the light and air required for their growth is diminished. Seeds cannot germinate and grow. Weeds can no longer compete with your plants for water and nutrients, and the garden bed will require less weeding and will showcase your plants instead of weeds.
provides nutrients - organic mulch decomposes over time into humus. Humus improves soil fertility as well as its capacity to retain water. Plants will be much healthier with ample nutrients and moisture.
Popular mulches for the Calgary area include shredded bark, bark chips and mature compost. As the mulch layer decomposes, replenish to maintain a depth of 2-3". Your garden will love it!
