Best Mulch for Perennials

Best mulch for perennials

There are different types of mulches and they provide various benefits to the garden.

Both organic and inorganic mulches insulate the soil, prevent weeds, and preserve moisture. But not both increase soil fertility and enhance the growth of plants.

Because perennials have a shallow root system and will have to find nutrients nearby, the best option is to use mulches that decompose quickly and provide nutrients to increase soil fertility.

This article provides a list of carefully selected mulches that are the best options for perennials.

The SpongEase Coco Fiber Mulch is similar to the one listed above. It also comes dehydrated and has to be soaked before use. In addition, it expands when soaked and you eventually get even more volume than the packed mulch.

A pack of this mulch covers approximately 4 square feet when spread 1-inch thick, and it covers approximately 2 square feet when spread 2-inch thick. The thickness you decide depends on what goal you aim to achieve. A thickness of 1-inch is enough to prevent the growth of weed. But if you want to conserve water, you should up the thickness to at least 2-inches.

This coco mulch is highly recommended if you want to mulch but you’re concerned about getting messy. It’s very easy and clean to use. And above all, it gets the job done as expected.

Benefits of Cocoa Shell Mulch

Cocoa shell mulch offers several benefits to perennials and plants in general. Below are a few benefits of using cocoa mulch.

1 It smells nice

Cocoa shell mulch is a nice material that gives off a pleasant chocolate aroma. This smell is often stronger after it rains or when you water your plant. It makes the environment conducive for as long as it lasts.

The scent from a fresh cocoa mulch can last up to a month before it wears off. You, however, have to be cautious if you have curious pets around as this could be an invitation to them. Chocolate is dangerous for dogs; eating this mulch could pose a risk to their health.

2 It is beautiful

The mulch has a brown rust color that’s pleasing to the eye. The color blends well with the soil to give a uniform appearance. The good thing about this natural brown is that it doesn’t fade off. It only gets darker after a while, which results in another unique beauty to behold.

Cocoa mulch is quite more eye-catching when compared with most mulches. This is one important feature that makes it a good choice for most gardeners.

3 It adds nutrient to the soil

Not only does cocoa shells give you the benefit of mulch, but it also provides nutrients that fertilize the soil. As the mulch decomposes over time, it releases nitrogen to the soil. This enriches the soil and in turn, enhances the growth of your plants.

Inorganic mulches like rubber mulch may only prevent weed and provide some other benefits but they don’t add nutrients to the soil like cocoa mulch. This is a great advantage cocoa mulch has over most types of mulches.

It is a highly recommended mulch for perennials because of the rate at which it decomposes.

4 It is easy to use

This is one of the easiest mulches to use. It doesn’t require a tedious process and you don’t have to get messy. The processed and dehydrated ones sold in portable packs are very light and easy to transport. Cocoa shell mulch is generally light.

The dehydrated ones only have to be soaked for some while before use. This will enable the mulch to expand and increase in volume. It lasts for a long time and won’t need to be replenished often.

Cocoa shell mulch is the choice of gardeners who don’t want to get messy and carry out tedious mulching tasks.

5 It invites friendly bacteria

Cocoa mulch invites friendly organisms like earthworms. These are organisms that positively contribute to the growth of plants. They aerate and provide nutrients to the soil. They do this by breaking down plant materials and converting them to soil rich in nutrients.

This is a natural process that greatly enhances the growth of the soil. You won’t have to worry about spending extra bucks on fertilizers anymore. This indirectly provides an economical advantage.

6 It prevents weed

The mulch is a great weed inhibitor. It hinders the growth of weed and allows you to weed less-often. Note that it may not completely eradicate weed but it mitigates the growth. This is a good feature that every gardener loves.

The cocoa mulch materials bind together after you water it. This forms a barrier that stops weeds from showing up. In some cases where plenty of weed don’t grow too often, the mulch will completely prevent weed.
