Return on your seeds

After all these years I've realised why I choose to grow certain veg in preference to others and its not a question of taste! 

My favourite veg to grow are courgettes, tomatoes, peas and beans. As much as I like the taste of carrots and cauliflowers I rarely try to grow them, not just because I find them difficult to grow properly, its because of the Return on each seed.

With carrots, for example, you sow a seed and, if you're lucky you grow a carrot. Pick it and you're left with a hole in the ground. You have to re-sow something in its place.
Sow a bean, however, and you can keep picking beans for weeks without needing to re-sow. The same with courgettes, tomatoes and peas - and peppers, of course. They're good investments because you can take a crop from them for a long time. They're also time saving, sow once, pick for weeks - so appeal to my lazy streak.
I'm also partial to growing loose leaf salads, kale and rocket for the same reason. Just pick a few leaves at a time and leave the plant to grow on.
I should try harder to grow sprouting broccoli and brussels sprouts as these would also suit my needs and stop trying to grow heading brassicas and root vegetables which are always a disappointment anyway.
