First of all you need to choose a sunny spot that will allow your tomato, courgette and strawberry plants to produce fruits and vegetables bursting with sun! Creating your kitchen garden close to a water access point is also a must, as your vegetables will sometimes need a little helping hand during hot spells!
Having chosen your spot, you need to clear the area of all weeds that could threaten your future cultivation. Use one of Roundup's ready-to-use multi-purpose weedkillers.
Two weeks afterwards you can begin to work the soil and remove all harmful elements such as stones, pieces of wood, etc. And there you are: all that's left for you to do is to sow and cultivate your fruit and vegetable plants.
