Mulching your garden
Mulches are materials placed over the soil surface to maintain moisture and improve soil conditions. This goes for every garden site, from vegetable garden to flower bed Mulch can reduce water loss from the soil, minimize weed competition, and improve soil structure. Properly applied, mulch can give landscapes a well-groomed appearance. However, Mulch must be applied properly; if it is too deep or if the wrong material is used, it can actually cause significant harm to trees and other landscape plants.
Mulched gardens are healthier, more weed free, and more drought-resistant then unmulched gardens, so you'll spend less time watering, weeding, and fighting pest problems.
There are two basic kinds of mulch: organic and inorganic. Organic mulches include formerly living material such as chopped leaves, straw, grass clippings, compost, wood chips, shredded bark, sawdust, pine needles, and even paper. Inorganic mulches include gravel, stones, black plastic, and geotextiles (landscape fabrics).
Both types discourage weeds, but organic mulches also improve the soil as they decompose. Inorganic mulches don't break down and enrich the soil, but under certain circumstances they're the mulch of choice. For example, black plastic warms the soil and radiates heat during the night, keeping heat-loving vegetables such as eggplant and tomatoes cozy and vigorous.
Using Organic Mulches
There are two prime rules for using organic mulches to combat weeds. First, be sure to lay the mulch down on soil that is already weeded, and second, lay down a thick enough layer to discourage new weeds from coming up through it.
Wood chips and bark mulch: You can purchase bags of decorative wood chips or shredded bark from a local garden center to mulch your flower garden and shrub borders. Or simply from carpenters, they have loads.
Shredded leaves: If you have trees on your property, shredding the fallen leaves creates nutrient-rich mulch for free.You can spread a wood chip or shredded leaf mulch anywhere on your property, but it looks especially attractive in flower beds and shrub borders. Of course, it's right at home in a woodland or shade garden. They also serve well as a mulch for garden pathway.
Grass offcuts: Grass trimmings are readily available mulch, although it's a good idea to return at least some of your grass clippings directly to the lawn as a natural fertilizer. Its fine to collect grass clippings occasionally to use as mulch, and the nitrogen-rich clippings are an especially good choice for mulching vegetable gardens. Your vegetables will thank you for the nitrogen boost!
Straw and hay: Great mulch for the vegetable garden is straw or hays. It looks good and has most of the benefits of the other mulches: retaining soil moisture, keeping down weeds, and adding organic matter to the soil when it breaks down. But be sure the hay you use is weed and seed free. Read more...
