Which One Is Better?
In short, both coco coir and soil have their strengths and weaknesses as growing mediums.
Coco coir may be a better choice for those seeking a renewable, organic medium with good water retention and drainage capabilities, while soil may be a more budget-friendly option that can provide necessary nutrients for plant growth.
It ultimately depends on the specific needs of the plants and the preferences of the grower.
Can I Mix Coco With Soil?
Coco coir added to soil is an excellent approach to boost plant health. Coconut husk has inherent drainage qualities and is a good water-retentive growth medium. Mixing it into your garden soil may help break up clay soil, making it more able to drain water.
When added to sandy soil, coco coir helps retain water so your plants don't dry out.
Compressed blocks or pre-measured sacks of coconut coir are available for purchase. Soaking it in water ensures that every part of it is damp before you combine it with soil.
If you're looking to give your plants a healthy growing environment, mixing coco coir with soil can be an excellent choice.
To use coir, soak the block or loose coir in a big tub or bucket. If additional water is required, continue adding it until it is well saturated.
After the coir is ready, it should be mixed with compost or garden soil until the coco-soil ratio is at least 50/50 coco soil mix. Additional additives like perlite, or lava rock may be added to potting mix to make it more plant-specific.
Remember to soak coconut coir before you dig it into your garden. The time it takes to soak will be well spent clearing the garden bed of pebbles, sticks, and dead plants.
Dig a shallow ditch, empty the coir into the ditch, and rake it with the compost and other nutrients over the garden. Digging it into a depth of 24 inches is recommended to incorporate the coco-soil combination fully.
To sum up, adding coco coir to your soil can quickly and easily boost plant health. Creating a nutrient-rich growth medium is as simple as doing a little bit of planning ahead of time.
Peat Moss vs Coco Coir: What’s the Difference?
Peat moss and coco coir are popular for soil amendments and growing media. Peat moss is a natural soil conditioner that is derived from decomposed sphagnum moss plants, which are found in peat bogs and wetlands. It has high water-holding capacity, good air exchange, and is acidic, making it ideal for acid-loving plants like blueberries and azaleas. I have several blueberry bushes and used a combination of peat moss and sand around the roots of my blueberry bushes.
In contrast, coco coir is a sustainable alternative to peat moss that is made from coconut fiber. It has good water-holding capacity but is less acidic than peat moss, making it more versatile in terms of plant selection. Additionally, coco coir is renewable, resistant to bacteria and fungi, and easy to work with due to its low dust content.
Overall, both peat moss and pure coco coir have their strengths and weaknesses and the choice between the two ultimately comes down to personal preference and the specific needs of the plants being grown.
