Potting Up Tools include such items as:
Plant Labels - these become essential when sowing a wide range of seeds as it's easy to forget what you've sown when the seeds are covered with compost.
Sieve - by simply removing any lumps or fibres from your compost before you sow means that roots won't be restricted within the compost and also lets you evenly cover the seeds with a fine, even layer of compost.
Dibber and Widger - these simple tools are designed to reduce the amount of handling of young seedlings, reducing the possibility of damage as you prick out and pot up.
Tampers - also known as 'presser boards', tampers are used to gently press down the compost prior to sowing, providing a level surface on which to sow seeds.
