We recommend to transplant your Croton every three years into the next sized pot with this potting mix. The only time that you may need to repot more often is if your plant is suffering from root rot. (Read the fifth question)
Selecting the bio-active selection incorporates both Worm Castings and Biochar, 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 your Croton's health by repotting during the autumn or winter.
Leaf loss on a Croton is either root rot or insufficient amount of light. The latter is rather easy to fix as all that's needed is to relocate the plant closer to a window. A good note to point out is that the plant can grow well in partial sunlight, so north, east or west-facing windows are ideal for Crotons. If, however, your plant continues to lose its leaves, there could be a chance that root rot is at play. Read the next paragraph to learn more about how to address this issue.
Yes! So, it's advised to repot your plant as soon as symptoms of root rot arises. Common symptoms could be rapidly yellowing leaves, browned new leaves that don't emerge successfully, and/or potential soil mould. Crotons grown more than 3m from a window are most likely to develop root rot, which can have symptoms of sudden leaf-loss, too. We recommend to take the plant from the pot and scan the outer edge of the potting mix. Root rot will look like brown, flat/deflated and can easily be pulled off from the soil (with little difficulty). There could be a slight 'earthy' smell to the soil, too. Healthy roots will be cream, light-brown or red in colour and will feel twig-like when lightly pinched. Follow the next steps to repotting your root rotted Croton 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 take stem cuttings and root them in either water or soil to 'restart' the root system.
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.
