  1. What Are the Advantages of Mulching with Compost?

Mulch made from compost has numerous advantages. It can aid plant growth in a variety of ways, from controlling pH to combating plant diseases. The following are some of the advantages of utilizing compost as mulch:

  • Boost the growth of your plants. 

  • Microbial Activity in the Soil Is Boosted.

  • Boost soil nutrition levels: Micronutrients in composted mulch include boron, cobalt, zinc, iron, and iodine. As a result, create the best conditions for plant growth.

  • Nutrients are released slowly into the soil.

  • Keeps moisture in.

  1. Is it possible for too much compost to harm plants?

Composting your soil with "black gold" provides a high dose of nutrients. Overdoing something good can sometimes result in a negative effect and the death of plants. Plant growth can be slowed by high quantities of soluble salts. Organic fertilizer with too much nitrogen, sulfates, and phosphorus causes the plant to burn. As a phosphorus antidote, iron is given to the soil. Phosphorus deficiency promotes the growth of mycorrhizal fungus in plants. Check to see whether it may hurt your field. It will be useful to perform an appearance test, since it should be in crumbled form.

  1. What is the Best Way to Mulch with Compost?

Compost mulching can be done in two ways. 

  • Make a clean, level soil surface and apply compost in a thin layer on top. Compost is sold in a granular form. As a result, worms and other beneficial insects will be able to penetrate deeper into the soil.

  • Another option is similar to the one stated above. Compost should be applied in a thin layer and should not be allowed to dry. Any type of dry mulch will prevent roots from growing properly. If the compost is dry, cover it with another layer of mulch. Chopped leaves, for example, will aid in water retention. And keep biologically active plants, such as fruits, vegetables, and flowers, alive.

  1. Is it possible to use sand as a mulch?

Sand, when utilized as a mulch, enhances the garden's attractiveness by contrasting the plant's greens with a white background. It also inhibits the growth of weeds and protects the topsoil from water loss as well as pests such as gnats and fungus. It can also be used as an amendment to improve the drainage and aeration of the soil.

  1. How to use compost for mulch in your gardens ?

To help filter out sunlight from budding weeds, a thick covering of mulch is preferable to a thinner layer. Apply a 2 to 4 inch (5-10 cm) layer of compost to the soil around all of your perennials, stretching the layer outward about 12 inches (31 cm). During the growth season, this layer will gradually work its way into the soil, so add more layers of compost mulch every month or so during the summer and fall.
