Benefits of using pine bark mulch in your garden.

Hold moisture in Soil:

Keeping the soil moist for growing plants is a very important step of gardening. But on hot summer days, it is not possible to keep the soil moist because the water get evaporates. It is also not possible to give water to plants 3 times a day. Even it is not allowed as per the law in some states.

Mulch protects the soil from hot sunrays and the water in the soil evaporates 75% less than ever before. It also keeps the plant roots temperature under control. In winters it acts as insulation and keeps the roots warm. Whereas in summer it protects them from direct hot sun rays.

Reduce weed problem:

It will reduce weed problems and also reduces the chances of nutrient deficiency in plants. The weeds will grow in unplanted areas and eat up all nutrients. When weeds are present in the garden plants always show signs of nutrients deficiency.

The mulch covers the unplanted area around your plants. And block the sunlight to weed seeds. They do grow because they do not get sunlight. On the other hand, your plants grow healthy because they get the full sunlight and a good amount of nutrients.

Add humus to soil:

Humus is naturally found nutrients in the soil by the decomposing of organic matter. Like in forests the upper layer of the soil is total humus. Because the leaves and branches of plants that fall on the area get decompose in the soil. This process adds a good amount of organic nutrients to it. Pine bark also add humus when it gets completely decompose into the soil.

Soil retention and erosion control

When you mix pie bark of medium size deep in the soil this prevents soil erosion. Soil erosion is the condition in which the upper layer of the soil gets depleted. The erosion process gets faster in windy areas. If you are living in the valley don’t worry about soil erosion. But if you live in hilly areas you need to consider pine barks.

Pine bark gives excellent color to your lawn and garden. if we compare pine bark with other mulches it retains its natural color for more than 2 years. Where other mulches fade due to sunlight in 6 months. Pine bark remain bright pinkish-brown for more than 2 years. The decoration is also necessary to make a garden beautiful and appealing.

Problems with pine bark mulch

Normally pine bark does not cause any harm to plants and the soil. But used for more than 5 to 6 years it alters the soil pH and eats up the nitrogen. This affects the growth of your plants and yield.

Pine bark mulch and soil pH: As we know pine bark is a little bit acidic this acid goes to the soil when used for a long time. And the soil becomes acidic in nature. This affects the pants that like to live in alkaline nature. But on the other hand, it is best to make alkaline soil a little acidic for growing plants like roses.

To prevent pine bark mulch from increasing your garden soil acidity. Use hardwood after every 2 years and then again use pine bark.

Pine bark nuggets: They cause problems only in heavy rainfall areas. Due to their big size, they start floating in the water. This is the only problem with the large size nuggets. Otherwise, they are best to use in sloppy places.
