There are many things that people do during the summer planting season when they get enthusiastic about growing. My neighbour plants tomatoes for instance every year. Tomatoes, potatoes and some herbs (Rosemary, chives, mint in particular) are easy to grow from seeds or cuttings. Sometimes people plant too many and I am lucky to have got plants from neighbours who then wanted to get rid of them.
However, having tried growing some herbs and berries from seeds, I would advise that it is definitely easier to buy some of these than growing them. These include Basil, thyme, parsley and strawberries. Supermarket herb pots (as recommended by some blogs) have been a disappointment so I tend to buy them from small nurseries or Kew Gardens. Strawberries can be notoriously difficult to grow from scratch, especially given the erratic weather. Here are some of the bought herbs compared to ones I grew from seed- see the parsley and thyme.
