Is Coco Coir Good For Succulents And Cacti?
Succulents and cacti are plants that will benefit from being grown in coco coir but only in certain conditions. If you have a succulent or cacti outside, which should only be done if you live in a humid climate, then coco coir is a good option. It will retain the minimum amount of natural watering.
However, if you own a succulent or cacti in an indoor setting, then coco coir isn’t as beneficial as you run the risk of overwatering your plant.
This will be an issue as you want your succulents and cactus to have a suitable amount of time between being in dampened soil and being in dry soil.
In these cases, you will need to have a suitable ratio of soil to coco coir. This depends on your specific type of cacti and/ or succulent.
I highly recommend you check treating succulents with neem oil.
Is Coco Coir Good For Monstera?
Monstera is a plant that will thrive if grown in coco coir but only if it is used in a ratio with soil. The ideal ratio of coco coir to soil for Monstera is 1:1. In this coco coir to soil ratio, the coco coir provides good drainage while the soil provides a bounty on nutrients.
Is Coco Coir Good As Drainage?
Coco coir retains moisture exceptionally well. Therefore, coco coir is not good for drainage when left naturally. However, it is easy to drain the moisture from coco coir as well.
In this case, if you are willing to put in the effort for a plant and have the time to do it, then coco coir is a good choice as it has the ability to drain well when forced to do so.
How Do You Prepare Coco Coir For Planting?
As coco coir comes in many different forms, the way to which you need to prepare your batch of coco coir for planting depends on your form of coco coir. You can buy prepared coco coir with added nutrients in which all you need to do is add it to your soil.
However, this is tricky as your pre-existing soil already has nutrients, and due to the fact that prepared coco coir only comes in small packs and can be expensive.
This is why the best form to buy coco coir in is in a brick format. All you need to do with a brick formed piece of coco coir is to add warm water and wait for it to break apart into a fluffy substance.
After this, you can add your prepared coco coir to your soil and, depending on your soil and/ or the plants you want to grow, determine and add the nutrients as needed.
Can You Mix Coco Coir With Potting Soil?
Since coco coir is neutral in acidity and has almost no natural nutrients, it is necessary to mix it with potting soil in order to grow any healthy plant.
Does Coconut Coir Mould?
Coco coir has the tendency to mould if it is overwatered along with having an excessive amount of added sugars.
