The importance of repotting plants:
- Give plants room to expand their roots and grow
- Prevent them from becoming pot bound (circling and entangled roots)
- Fresh soil and nutrients for plant vitality
- A bigger pot holds more soil – more soil holds more water – less frequent watering required
Mulching (for example using wood chips) even potted plants has many advantages:
- Quality long term fertility
- Stop sun from heating soil and drying out plants
- Stop UV light from killing soil life (never leave soil open / without cover)
- Creates insect and microbial habitat adding nutrients and heat to soil
- Stop weeds and grasses
- Hold water
- Stop frost
