When to Repot Orchids?
When it comes to repotting orchids, there are a few things that you should check and then move on to the next step.
First, if the orchid has outgrown its container, it’s time to move. Usually, you can notice this if the roots are starting to grow over the stem or the container sides.
Also, don’t forget that the potting mix is the source of nutrients for the orchid and if you notice it’s gone bad, then you should move to repot.
It’s recommended that you repot the orchid every year or every other year, however, if you notice any changes and decay earlier it’s better to be safe than sorry. Moreover, if you feel an odor around your orchid it might be a sign of root rot due to improper drainage then it’s time to change the potting mix.
Additionally, you should have in mind that different types of orchids can be repotted during different seasons; thus, make sure you treat them separately when it comes to repotting processes.
In most cases, you shouldn’t repot orchids when flowering.
How to Re-Pot An Orchid?
When repotting an orchid, it’s essential to consider a few things. First and foremost, think about the type of container you’re going to use – ideally, it should be bigger in diameter than the old one, not too much but an inch or two will do the job.
Moreover, some containers are made especially for orchids and they have holes on the surface. These holes provide air to get around the roots and proper water drainage.
Orchids are very delicate flowers, so when taking it out of the container make sure you are gentle and careful and always check the roots’ condition. Make sure you cut any damaged roots and then place the orchid in the potting mix and add enough soil around the roots.
What are The Different Orchid Potting Mediums?
As we mentioned in our review section and you probably know, there are different types of orchids. And while some of them can grow in soil, others require to have a different soil medium – like the ones we presented.
One of the most important features of a good potting soil mix for orchids is aeration i.e. providing enough room for the roots to breathe and develop.
One of the ingredients that are most commonly used in orchid potting mixes is fir bark. This ingredient can be of 3 types i.e. thick, medium and fine bark. The fine fir bark can hold moisture for longer and it works great with young orchid flowers.
The coarser the bark, the faster it can dry and allow more air to pass through. When using fir bark make sure you choose the right type depending on the orchid. For instance, bigger orchids require larger 1-inch fir bark, medium roots require ½ inch fir bark and fine bark is used for orchids for smaller roots.
Sphagnum moss is a good option for orchids that don’t dry out fast. When using this type of potting mix, be mindful of the acidic pH since it doesn’t work well with certain types of orchids.
When using sphagnum moss for repotting make sure you pot very loosely to ensure there’s enough oxygen for the roots.
As mentioned before, this is a very absorbing medium that can absorb the fertilizer salts and that’s why you have to repot the orchids at least once per year. If you wait too long, the leaves will turn yellow since the plant will be losing healthy fibers due to salt decrease.
This is another popular option that’s used for orchid repotting and it’s usually combined with fir bark. It’s not a good absorbent of water but it can absorb the fertilizer and that’s why it’s best to change it every year and never re-use it.
Perlite is usually added to fir bark and the best one for orchids should be chunky. It’s lightweight and doesn’t absorb water
Coconut husks & gravel
Coconut husks are similar to fir bark but provide more moisture and don’t break down fast. Sponge rock provides great airflow and moisture retention.
Why is The Potting Mix Important?
Using a quality potting mix for orchids can provide great bloom and help you grow robust orchids that are a pleasure to watch.
Nevertheless, it all starts from the roots and you have to prepare a strong base to grow the best orchids. That’s where the potting soil mix comes into place.
Before making a purchase, make sure you analyze the characteristics of the brand you want to use. Some of the features that you need to consider are the water retention, drainage and aeration properties of the mix.
By choosing the right product from the very start, you can avoid repotting every 6 months and see long-term results.
