This will often raise that perennial question;
Which ones do I need?
A simple enough question but sadly one that has no definitive answer!
Many factors can influence the final selection for example;
Preference and Affordability!
Perhaps a fair starting point could be; buy the best quality you can afford!
Having said that, cheap tools can often work out more expensive in the long term because they can rapidly wear out or break,meaning they have to be replaced after a short time.
Some better quality tools may last a life time cheaper ones rarely do!
The following appraisal might help answer ther question!
Initially a starter kit of a Spade, Fork, Hoe, Rake, Hand trowel, Hand fork, Dibber / Bulb planter, should cater for most of the tasks the novice gardener is likely to require in his/her first year.
In the fullness of time there are a number of other tools that he / she might need.
a watering can / hose pipe to ensure their plants don't go dry.
a wheelbarrow to cart soil from one end of the bed to the other when double digging, or to carry organic matter from the compost heap.
Then there are such things as hand / pump sprays to keep pests and diseases at bay.
The list can go on and on, but it would suffice to say that if the new gardener has the tools listed above, these will cater for most of the gardening tasks that they are likely to be faced with as a novice gardener.
Other tools can be purchased as and when the need arises!
