For those who have stumbled onto this article - welcome! Feel free to read my no-nonsense top tips into successful repotting, but if you're surfing the web for the best potting mix around for your houseplants, have a look on my web-shop here!
• For plants situated in dark locations, add some perlite to the lower portion of the new soil (which will be located in the bottom third of the pot surrounding the rootball). As the combination of over-watering and too little light go hand-in-hand, improving the soil's drainage will significantly reduce the chance of root rot.
Alternatively, for those that are placed in direct sunlight or high temperatures, improve its water-retention by adding coconut coir or bark. These ingredients will retain the moisture for longer, thus reducing the chance of dehydration.
• Create an indoor garden or display by bunching plants that have similar soil requirements (well-draining, ericaceous, carnivorous, etc.). If the display is successful, after a few months you'll have to water it more frequently - this is due to the ratio of soil-roots favouring the latter, which means your roots are healthy. Have a look at the image below to see ours that was created back in 2018!
• For plants that grow predominantly in one direction, for example, a single-sided vine, move the rootball backwards to what would be the front of the pot (where the foliage sits). Phototropism will cause roots and foliage to grow towards the light, meaning that there will be more roots at the front of the pot, and less at the back. Placing the plant towards the back of the container will allow the roots to fill the whole pot and not just the well-lit-side.
• Finally, if you're thinking of repotting a vine that is growing up a moss pole, never remove attached aerial roots as the disturbance could put further stress on the plant. Extend by purchasing another same-sized pole and pushing directly into the hollow hole in the original's top - its moss-like material may have to be cut off from the top to access the hollow centre. Get a long, sturdy stick that has a similar length to the two poles combined and place in the two's centre to support the weight. Always perform the repot BEFORE adding another pole, as it'll prove more challenging due to the weight distribution and overall balance. N. B. - You'll only have to repot trailing vines every two or three years (except annually for Monstera) - if their pole needs extending, you can do this without the need for a transplant.
Transplant shock is where the roots and their hairs have been over-moved or damaged, predominately during a repot. Avoiding this issue is easy - give the plant a good soak 24hrs before the action and NEVER tinker with the roots, unless you're dealing with root rot or splitting the crown via propagation. This 'soaking' period should occur whilst the plant is still in its original pot.
Symptoms are closely similar to dehydration - wilting, stunted growth and the yellowing of leaves are all typical signs of a stressed plant.
For a better comprehensive, ukhouseplants have categorised transplant shock into two tiers - mild and severe. Note that if your plant is wilting has rapid lower leaf loss while being sat in overly moist-soil, root rot may be to blame.
Mild - Slowed growth, a slight greying or yellowing of foliage and flower loss are all signs of mild transplant shock. Keep on top of watering, humidity levels and always provide a location with a generous amount of indirect light. Do not unearth the roots again as this will only add to its misery. Although the already-yellowed leaves will be a permanent fixture, new growth will soon take over once the plant regains its strength. If the foliage continues to wilt, do not fall in the trap of over-watering. Remember that the roots are damaged and NOT dehydrated - keep the soil evenly moist, allowing the top third of the pot to become dry in between waters.

Severe - The continuation of wilting, yellow or greying of foliage and stunted growth that are still prominent after a few weeks are all symptoms of severe transplant shock. As the chance or survival is minimal, there are two options. You can either wait for new growth or consider propagation if the plant continues to decline. Woody plants like Dracaena, Ficus, Schefflera & Yucca can all be propagated via stem cuttings, whereas others are separated by 'pup' or offsets. If the plant loses all of its leaves, survival will be highly unlikely, so the only sane option is to discard.
