When I first started planting in small pots, I used dining table spoon and fork as my tools- Normal size gardening tools in the shops are all too big for the delicate tasks. My dad had the same problem too as he does small scale planting on his balcony.
It is ok to use the usual spoons and forks as they do the job. Or you can get patio tool sets from the shop but they are not that cheap (at least £20). I decided to find a cheaper alternative- children gardening tool set. It only cost a fraction of the price!
The trick is to pick the ones that are made of stainless steel, not pastic. They work just as well. Ok, you have to bear the colourful bag but the tools are just as good. The photo shows the set by SoGifted. It only costs £8.50.
