Tips for Growing Vegetables Faster
Want even quicker harvests? These simple tricks can help.
Start with quality compost
Healthy soil helps plants establish quickly and grow faster.
Keep plants watered
Vegetables that dry out often stop growing while they recover.
A consistent watering routine makes a huge difference.
Feed regularly
Fast-growing vegetables use lots of nutrients.
Liquid vegetable fertiliser every couple of weeks can noticeably improve growth.
Grow in full sun
Most vegetables grow much faster when they receive at least six hours of direct sunlight every day.
