As a general rule of thumb, Orchids will like to be repotted every two to three years to refresh its potting medium. Never repot your Orchid while it's in bloom, unless it has developed root rot. In this case, it's important to prune off the dead, brown roots immediately and repot the plant. Symptoms of root rot are the leaves beginning to wilt, curl or soft/flop over, despite its potting mix still being moist. Scroll down to the eighth question to learn more.
Selecting the bio-active selection incorporates both Worm Castings, which both will help with the overall health of your new potting mix. The soil will promote a better relationship with the root system, which in turn will aid the plant’s wellbeing, photosynthesis and ability to deal with pests/diseases like root rot!
Yes! There are no issues in terms of affecting an Orchid's health by repotting during the autumn or winter. As long as your Orchid isn't currently flowering, you're free to repot throughout the year.
Firstly, flowers that gradually fall off are completely fine. Each individual flower will only bloom for around two months (depending on the species). If, however, the majority of the leaves are falling off, this could be a case of environmental shock. It's a good idea to prune the flower stem back by around half, so that it can produce a new flower spike further down on the stalk. The already-yellowing or browning flowers will continue to decline and there's nothing that can be done to save those ones.
You'll want to keep the Orchid's foliage above the moss at all times, so try not to submerge them. In most cases, this means the plant will be simply 'sitting' on top of the Moss (instead of in it), which is fine as the Orchid will begin to re-root into the moss at a later date. Recovery times for root rotted Orchids is around four months when using Mix 3.
This is entirely up to you. It's perfectly fine to keep your Orchid indefinitely in the moss as this is a superb growing medium for these plants. If you're wanting to repot it back into the bark (either Mix 1 or 2), we recommend waiting until the roots are around 6cm (2.5in) in length.
No. Always make sure the moss stays moist while the Orchid is repotted in it. You don't need to wait for the moss to dry out before rehydrating it; simply water it every few days to ensure it's wet using the mindset of 'little and often'.
Yes! We recommend selecting Mix 3 as repotting with Sphagnum Moss will help the dying root system recover well. It may take around four months to see signs of new leaves (and/or flowers), but it'll be worth the investment as it can make a full recovery. It's also very difficult to over-water Sphagnum Moss as long as the Orchid's pot isn't submerged in a pool of water at the bottom.
How to Repot An Orchid With Root Rot
So, it's advised to repot your plant as soon as symptoms of root rot arises. Common symptoms could be rapidly yellowing leaves, wilting/curling/floppy leaves and brown, dead roots within the potting mix. Healthy Orchid roots will be either cream or silver in colour, whereas root rot will always be brown. Orchids grown more than 1.5m from a window are most likely to develop root rot, which can have symptoms of sudden leaf-loss, too. Follow the next steps to repotting your root rotted houseplant with one of the options;
Option 1: If more less than 20% of the roots have rotten, remove the dead roots with scissors and replant it back into its original pot, using fresh new this compost.
Option 2: If roughly between 20% - 80% of the roots have rotten, We recommend removing the dead roots and repot into a smaller pot. One that is around 3-5cm smaller in diameter is best, along with using this potting mix.
Option 3: If more than 80% of the roots have rotten, it's recommended to choose Mix 3 and repot the Orchid back into the orignal pot with the Sphagnum Moss. Don't bury or submerge the leaves in the moss, and instead keep the leaves above the moss at all times. This may mean that the Orchid is just 'sitting' on top of the moss, which is acceptable as it'll begin to re-root when the is kept moss moist during the recovery of around four months.
We always recommend watering your houseplant around 12 hours before potting so that the plant is hydrated and strong enough for its repot. If you forget to water beforehand, it's not the end of the world as long as you're very gentle with the root system. It's also advised to wait two days before giving the plant another water again, just so it gives enough time for your plant to settle into its new home.
It's best to keep the lid of the potting mix slightly ajar by around 20% to help it have aeration while in storage. The best place to store the potting mix is in a cool, dark shelf or cabinet until you need it next.
To successfully germinate Orchid seeds, you'll need Agar Jelly as this is a specialist job that's difficult to achieve.
