If you’re wondering what to put down before mulching, you’re not alone. Mulching is a great way to keep your garden healthy and beautiful, but it’s important to prepare the area properly before laying down the mulch. There are a few steps you can take to prepare your garden for mulching, and Onyx Landscape is here to guide you through the process.
First, it’s important to clear the area of any weeds or debris. You can do this by pulling weeds by hand or using a garden hoe or hand weeder. Once you clear the area, you can add a layer of compost or landscape fabric before laying down the mulch. This can help improve soil quality and prevent weeds from growing through the mulch.
When it comes to choosing and applying mulch, there are a few factors to consider, such as the type of plants in your garden and the climate in your area. Different types of mulch have different benefits and drawbacks, so it’s important to choose the right one for your needs. Applying the mulch evenly and at the right depth will help your garden stay healthy and beautiful.

Preparing Your Garden for Mulching
Before applying mulch to your garden or yard, it’s important to prepare the area properly. This will help your plants receive the nutrients they need from the mulch while inhibiting weed growth and pest infestations.
Here are a few steps to follow to prepare your garden for mulching:
Assessing Your Landscape
The first step in preparing your garden for mulching is to assess your landscape. Take a walk around your yard and identify any areas that need special attention. Look for debris, weeds, and leaves that need to be cleared away. Take note of the types of plants in your garden, as well as the amount of sunlight and water they require. This will help you determine the type of mulch that is best for your garden.
Clearing and Cleaning the Area
Once you’ve assessed your landscape, it’s time to clear and clean the area. Use a rake to remove any debris, leaves, or weeds from the area. Be sure to wear gardening gloves to protect your hands from any potential hazards. If you have a lawn, use a pre-emergent herbicide to prevent weed growth before applying mulch.
Applying Soil Treatments
After clearing and cleaning the area, it’s time to treat the soil. This will help your plants receive the nutrients they need to thrive. Organic materials such as compost help improve the soil’s structure and fertility, providing a healthy foundation for your plants to grow.
Choosing and Applying Mulch
Selecting the Right Mulch Material
When it comes to selecting the right mulch material, there are a few things you should keep in mind. The type of garden beds you have and the plants you are growing determine what type of mulch is best for your needs.
Organic mulches, such as wood chips and straw, are great for flower beds and vegetable gardens, as they break down over time and add nutrients to the soil. Inorganic mulches, such as stone and rubber mulch, are better suited for shrubs and trees, as they do not break down and can last for years.
Proper Mulching Techniques
Once you have selected the right mulch material, it’s important to apply it properly. Start by measuring the square footage of your garden beds to determine how much mulch you will need. You can use a mulch calculator or consult with a professional team like Onyx Landscaping to determine the correct amount.
Next, gather your tools, including a shovel and wheelbarrow, and begin to lay mulch around your plants. Be sure to leave a small space around the base of each plant to prevent moisture buildup and potential rot. A good rule of thumb is to apply a 2-3 inch layer of mulch around your plants.
As you lay mulch, be mindful of the depth and spread it evenly throughout your garden beds. This will help maintain a consistent temperature and prevent moisture loss.
Maintaining Your Mulch
After you apply your mulch, it’s important to maintain it properly. Periodically rake your mulch to aerate it and reduce the need for watering. If you notice your mulch starting to thin out, you can add more to even out the space and create a cohesive appearance.
In colder months, mulch is a great option for insulating your plants. By adding an extra layer of mulch in the fall, you can help protect your plants from frost and freezing temperatures.
Choosing and applying mulch is a simple and effective way to improve the health of your garden beds. By selecting the right mulch material, applying it properly, and maintaining it regularly, you can help retain moisture, regulate temperature, and prevent erosion in your garden.

How should mulch be applied over existing soil?
Before applying mulch over existing soil, it is important to remove any weeds, debris, and dead plant material. Once the area is cleared, spread a layer of mulch evenly over the soil. Make sure not to pile the mulch too high around the base of plants or trees, as this can cause damage.
Is it necessary to remove all weeds prior to mulching?
Yes, it is important to remove all weeds prior to mulching. Weeds can grow through the mulch and compete with your plants for nutrients and water. If you don’t remove weeds before mulching, they will continue to grow and spread, making it more difficult to control them later.
What preparations are needed before laying mulch around a house?
Before laying mulch around a house, it is important to clear the area of any debris, including rocks, sticks, and leaves. You should also trim any overhanging branches or shrubs to prevent them from touching the house. If you have foundation plantings, make sure to leave a gap between the mulch and the foundation to prevent moisture from accumulating and causing damage.
Can mulch be placed on top of old mulch, and how is this done effectively?
Yes, mulch can be placed on top of old mulch, but it is important to remove any debris or dead plant material first. You should also make sure not to pile the mulch too high, as this can cause problems with drainage and air circulation. Ideally, you should aim to maintain a total mulch depth of no more than 3 inches.
What materials are recommended for weed prevention under mulch?
There are several materials that can be used for weed prevention under mulch, including landscape fabric, cardboard, and newspaper. These materials help to smother weeds and prevent them from growing through the mulch. It is important to make sure that the materials are laid down evenly and overlap slightly to prevent gaps where weeds can grow.
What steps should be taken to properly mulch a flower bed?
To properly mulch a flower bed, start by removing any weeds or dead plant material. Then, spread a layer of mulch evenly over the soil, making sure not to pile it too high around the base of plants. It is also important to leave a small gap between the mulch and the stems of plants to prevent moisture buildup and damage. Finally, make sure to maintain a total mulch depth of no more than 3 inches.
