Repotting trees is a great way to give them a fresh start and help them grow healthier. Winter is the best time to transplant as Trees are not actively growing.

Steps to follow when repotting a tree:

1. Choose the right size pot: Make sure the new pot is slightly larger than the old one so that the tree has enough room to grow. Also, ensure that the new pot has drainage holes at the bottom to allow excess water to escape.
   
   
2. Prepare the new pot: Fill the new pot with fresh potting soil. You can also add some slow-release fertilizer to give the tree a nutrient boost.
   
   
3. Remove the tree from its old pot: Carefully remove the tree from its old pot by gently tapping the sides and bottom of the pot. If the tree is stuck, you can use a knife to loosen the roots from the sides of the pot.
   
   
4. Prune the roots: Use sharp, clean scissors or pruning shears to trim away any damaged or dead roots. You can also trim any long roots to encourage new growth.
   
   
5. Repot the tree: Place the tree in the new pot and fill in the gaps with fresh potting soil. Make sure the tree is planted at the same depth as before and that the soil is firmly packed around the roots.
   
   
6. Water the tree: Give the tree a good watering to help settle the soil and ensure that the roots are well hydrated.
   
   
7. Place the tree in a suitable location: Finally, place the tree in a location that receives the right amount of sunlight and is protected from extreme temperatures and winds.
