Bright flowers, green grass, and well-trimmed bushes are the typical targets of our admiration for gardening and landscaping. On the other hand, mulch is a true hero that helps keep our gardens healthy and beautiful without ever being noticed.
Mulch, that seemingly small covering of organic or inorganic particles, is crucial to the success of your garden. It improves the quality of your soil, and your landscaping looks great as a bonus. Mulch offers many benefits to a garden, but it needs to be maintained regularly to keep working.
This article will discuss why mulch is essential for horticulture and landscaping projects. We’ll talk about the different kinds of mulch, how they might help your garden, and why you should give this element the attention it deserves. Let’s explore why mulch is essential to successful gardening and why it requires regular maintenance.
Come with us as we explore what is beneath the soil in your garden and discover the importance of mulch and how to best care for it. Learn more about mulch and how to properly care for it, whether you’re an experienced gardener or just getting started. All right, let’s get started!
Types of Garden Mulch: Benefits and Drawbacks
Compost
Our preferred mulch for our raised garden beds is compost. Do you lack composting experience? Compost can be made from various organic materials, including plant debris and animal manure, as long as it has been adequately broken down. Compost can be manufactured at home or bought pre-packaged or in bulk.
Benefits
- Compost has three purposes: it slows runoff, insulates plant roots, and feeds the soil’s ecosystem. Not only does it serve as mulch, but it is also a significant source of natural fertiliser for our plants.
- Compost is a very sustainable and eco-friendly material since it is made from waste that would have ended up in a landfill otherwise, such as food, landscaping, and animal waste.
Drawbacks
- Unlike other mulch types, compost decomposes quickly and must be replaced more frequently. We top off our raised beds with new compost during the fall and spring crop rotation and amendment periods.
- Plants can be damaged by the high quantities of nitrogen found in uncomposted or recently used animal manures. If you will utilise compost made with animal manure, ensure it’s been aged properly.
Straw
Barley, wheat, and oat straw are typically used as mulch. Straw is not the same thing as hay. The dry byproduct of cereal crops is straw. There may be a few seeds in there if you’re lucky. Hay, on the other hand, is grass explicitly grown to feed animals, and it typically contains weed seeds that will germinate and cause chaos in your garden.
Benefits
- Straw is easily accessible and doesn’t cost much.
- It breaks down to replenish the soil with nutrients and new organic material.
- Once you’ve untied the bale, the hay is relatively light and simple.
Drawbacks
- Your garden could be contaminated using straw sprayed with pesticides or herbicides. The application of contaminated straw mulch can cause even well-established plants to wilt and die within a single day.
- Straw is perfect for hiding rodents, insects, and other pests around your plants. This is a problem with all mulch, but straw provides an exceptionally conducive environment.
Mulch Made of Bark or Wood Chips
Many different sizes and shapes of bark or wood chips exist, including huge bark nuggets, wood shavings, little bark, and shredded bark. You may find bagged bark products at any garden centre. Finding a tree service or landscaper who carries bulk bark or wood chips in your area should be simple.
Benefits
- Bark effectively prevents weeds’ growth when put in a thick enough layer.
- Using tiny shredded bark or wood shavings around delicate vegetables and flowers and chunky bark in paths or borders are just two examples of the many landscaping uses for the great variety of wood mulch materials available.
Drawbacks
- Bark mulch does require occasional replacement due to decomposition. However, how often you need to do this may vary greatly depending on your local environment and the size or type of bark mulch you have installed.
- Ground-dwelling bees and bumblebees native to the area cannot tunnel through thick bark. If you want to promote pollinators in your garden, leaving some bare soil exposed is ideal or using compost as mulch.
Crushed Stone, Gravel, or Rock
You can use anything from pea gravel to crushed granite for this. Although gravel can serve as mulch, we typically consider it a landscape component. Gravel (3/8″ green rock) and massive cobblestones (used as borders for perennial beds) are familiar sights in one’s front yard garden.
Benefits
- One of the most resilient and long-lasting mulches is rock gravel. Unlike other types of mulch, gravel shouldn’t need to be replaced after the first investment and placement.
- Gravel mulch is typically not easily blown or washed away by weather conditions.
Drawbacks
- Although gravel can provide some protection, it does not feed the soil like organic mulch components.
- Despite its insulating and condensation-blocking benefits, rock can emit too much radiant heat in some environments.
How to Know Whether Your Mulch Needs to Be Replaced?
Indicators that your mulch needs to be replaced include:
Nature and Weather
Whether you use natural or synthetic mulch, it can be blown away and replaced by the weather. Mulch, significantly finer materials like sawdust and straw, can be lost in floods or blown away by strong winds. Animals can also destroy mulch if they burrow under it.
If you notice that your mulch layer is getting thinner or there are bare places, you may need to add more.
It’s Been Long Enough
When you put down new mulch, mark the date on the calendar so you know when to expect to have to do it again. Mulch should be replaced at the recommended intervals; however, you should watch it for other reasons to prevent you from doing so.
Mulch should be replaced twice yearly, in the spring and fall. Don’t put it down too soon in the spring; you’ll stunt new growth and halt the soil’s warming process.
Decomposed
Decomposition rates of organic mulch may also be higher than expected. Soil moisture, temperature, and regular rainfall can all contribute to a faster decomposition rate. Keep an eye on the weather and how it can affect your mulch in the yard.
As time passes, your organic mulch will lose its vibrant hue and finally decompose entirely. It’s okay if it still has the same texture and appearance as when it was first laid down, but it needs to be replaced if it’s starting to resemble the soil around it.
Weeds Begin to Grow
If you’ve noticed an uptick in weeds, mulch may no longer keep them at bay. Over time, this is possible if your mulch decomposes and thins, allowing weed seeds more access to soil and light.
Fungus
Fungus is another problem that can develop in organic mulch. Wet weather is a common trigger for this phenomenon. Most of the time, you shouldn’t eliminate the fungus growing on your mulch because it aids in decomposition. However, you can scrape some varieties of fungus away and dispose of it if you’re worried about pets or children eating any renegade mushrooms or if you don’t like the look of it. If the fungus is a persistent problem, try replacing your mulch with something else.
Removal of the infected mulch, fungicide treatment of the area, and subsequent re-mulching should be performed if artillery fungus develops in your mulch.
Plants Are Having a Hard Time
If your plants are still struggling after applying mulch, try a different method. Your mulch must be thick enough to protect your plants or has disintegrated and stopped enriching the soil.
When Should You Replace Your Mulch?
Mulch plays a crucial role in the success of any outdoor space. Water retention, plant nutrition, and weed suppression are all benefits of mulching. However, mulch can degrade and lose its effectiveness over time.
But how frequently should mulch be changed? It loses efficacy if not replenished frequently. This post will explain how often you should replace your mulch to ensure your garden always looks its best.
The amount of wear and tear, the amount of water and sunlight the mulch gets, and the type of mulch all play a role in determining the response. The timing of replacement can shift depending on these variables.
Mulches made of organic materials need to be renewed every two to three years, while inorganic mulches can stay in place for five years or more. How often mulch should be updated depends on several factors, including the quality of the mulch and the weather.
Organic Mulch
- Straw- 1 Year
- Grass Clippings- 1 Year
- Wood Chips- 2-3 Years
- Leaves – 1-2 Years
- Bark- 2-3 Years
- Pine Needles- 2-3 Years
- Compost- 1-2 Years
- Newspaper- 1 Year
If your inorganic mulch has changed colour or become mossy, it’s time for a replacement.
Inorganic Mulch
- Gravel- Indefinite
- Pebbles- Indefinite
- Landscape Fabric- 3-5 Years
- Rubber- Indefinite
- Black Plastic- Indefinite
How to Replace Mulch
Mulch is an excellent tool for preserving the beauty and vitality of your garden. It prevents plant damage from frost and heat, moistens the soil, and improves quality.
When mulch deteriorates or loses its effectiveness, it is crucial to know how to replace it. Mulch must be changed frequently to ensure a healthy environment for your plants.
Changing your mulch is an easy way to have your garden looking better, weed-free, and more hydrated.
Changing your mulch is a quick and easy task that requires only a few essential tools. The procedures for reapplying mulch to a garden bed are detailed in this article.
- First, rake up and properly dispose of any existing mulch.
- The next step is to replace the old mulch with something more suitable for your garden in terms of wetness and texture.
- The final step is to moisten the soil well once a fresh layer of mulch has been put over it.
What Happens If Old Mulch Is Not Replaced
Mulch should be replaced often to keep a garden in good condition. Plants may grow stressed and prone to disease if the mulch around them isn’t replaced regularly.
Mulch should be replaced periodically to prevent soil compaction, nitrogen depletion, and weed growth. Damage to your garden’s plants can also be caused by old mulch, which provides a haven for weeds and pests.
Mulch helps keep the soil moist, which weeds need to grow. Protecting plants from severe temperatures and maintaining soil aeration are two additional benefits.
If you replenish your mulch regularly, you may recapture these advantages and watch your garden flourish.
Keeping your plants healthy and thriving requires regular mulch replacement.
Therefore, failing to replace old mulch can have numerous unfavourable implications on your garden’s health and appearance. Mulch serves several vital functions, including weed control, soil moisture retention, and erosion control.
Over time, mulch can become compacted, resulting in poor drainage and increased weed growth if not periodically changed.
In addition, if you use several years old mulch, it may have pests or illnesses that could be transferred to your other plants. Keeping your garden healthy and looking its best requires frequent mulch replacement.
