Mulching is a beneficial gardening practice that involves covering the soil around plants with a protective layer of material. Mulch serves multiple purposes, such as retaining soil moisture, suppressing weed growth, regulating soil temperature, and improving soil fertility.

Let’s explore different things you can use as mulch when planting:

1. Wood Chips and Bark Mulch: Wood chips and bark mulch are popular choices for mulching due to their ability to suppress weeds, conserve moisture, and gradually improve soil quality as they break down. They are commonly made from chipped or shredded wood and come in various sizes and textures. Cedar and pine wood chips are particularly prized for their natural insect-repellent properties. There are services like Chip Drop that can supply you with free woodchips as well as many cities give them away for free. You can also try calling a local tree company and asking for them, they are often happy to get rid of them.

2. Straw and Hay: Straw and hay are classic mulch options, especially for vegetable gardens. They create a light and airy mulch layer that helps keep the soil moist and suppress weed growth. Straw is particularly useful for winter mulching, protecting plants from frost damage. This is a little harder to make in a suburban environment, so you will likely have to purchase it.

3. Leaves: Leaves are a readily available and cost-effective mulching option, especially in the fall when trees shed their foliage. Shredded or whole leaves can be used to insulate the soil, add organic matter, and promote earthworm activity. However, avoid using leaves from walnut or eucalyptus trees, as they may contain compounds toxic to some plants. We recommend mulching them up with your lawn mower, bagging them, and storing in a dry place until you need to use them.

4. Grass Clippings: Fresh or dry grass clippings from the lawn can be an excellent mulch option for vegetable gardens. However, use them sparingly and in thin layers to avoid matting, which could prevent air circulation and lead to odors or mold growth.

5. Compost: Compost is a valuable mulching material that not only helps retain soil moisture and suppress weeds but also enriches the soil with nutrients. Applying a layer of compost as mulch provides a slow-release source of organic matter that benefits plants over time.

6. Newspaper and Cardboard: Newspaper and cardboard can be used as biodegradable mulches to suppress weeds and conserve moisture. Wet the paper or cardboard before laying it down to prevent it from blowing away. Avoid using colored or glossy paper that may contain harmful chemicals. Also, remove any tape from the cardboard.

7. Seaweed: For coastal gardeners, seaweed is an excellent mulching option. Seaweed is rich in minerals and nutrients, which can benefit the soil and plants. Rinse the seaweed in fresh water to remove excess salt before using it as mulch.

8. Pine Needles: Pine needles, also known as pine straw, are a durable and attractive mulch option for acid-loving plants like azaleas and blueberries. They break down slowly and help maintain soil acidity.

9. Gravel and Stone: In certain landscaping scenarios, gravel and stone can be used as mulch to create a decorative and low-maintenance ground cover. They work well in drought-tolerant gardens and around succulent plants.

Tips for Mulching:

  • Apply mulch in a layer about 2 to 4 inches thick for most plants. However, some plants, like strawberries, prefer a thinner layer.
  • Keep mulch away from plant stems and trunks to prevent rot and pest issues.
  • Replenish mulch as needed to maintain the desired thickness and benefits.
  • Experiment with different mulch materials to determine what works best for your specific garden and plant needs.

In conclusion, mulching is an essential practice in gardening that offers numerous benefits to plants and the soil. From traditional wood chips and straw to unconventional options like seaweed, there is a diverse range of materials you can use as mulch when planting. Consider the specific needs of your garden, the type of plants you’re growing, and the availability of mulch materials in your area to choose the best option for your garden’s success. By incorporating mulching into your gardening routine, you’ll create a thriving and beautiful landscape that yields bountiful harvests and flourishing flowers.
