Good quality, fresh salad is expensive.
The good news is that you can grow even higher quality, better flavoured salad at home in containers – all for a tiny fraction of the price (if you use recycled materials, almost free!). And by growing it at home, you can pick it fresh whenever you want it.
Salad is amongst the easiest crops to grow in containers and one of the most productive. Because it only needs a few hours sun a day, its a good choice for the more shady balcony or window sill. And by sowing it regularly, you can enjoy a constant supply of leaves throughout the year.
What’s more, many of the exotic salad varieties and micro leaves, are not difficult to grow either. Some – like sorrel and the mustards – are almost impossible to buy and can normally only be found in the top restaurants.
The Vertical Veg Club this month is looking at ways to grow food in containers for free or at low cost. In this short excerpt video, author, trainer and cook, Tom Moggach, shares how he grows delicious mustards on a shoestring. For more great urban growing advice – and some top notch recipes – check out Tom’s book, the Urban Kitchen Gardener.
More tips for growing salads at low cost
Almost any container of 3 – 10 inches (7 – 25 cm) deep is good for growing salads. Shallower containers, like the ones Tom uses in the video, are perfect for small salad leaves. If you want larger leaves, use a container with more depth. There are many different types of trays you can find for free that are perfect including: mushroom trays, fruit trays, and polystyrene fish trays. Because these trays are not always the most attractive, you might want to use your creativity to make them more beautiful. One simple idea is to hide the trays behind a wooden board.
If you have space you can make your own compost and mix it with leaf mould to make a free compost. Alternatively, in many cities you can now get green waste compost for free or at low cost. A third option is to try and find a community growing project that buys compost in bulk – they’ll often be able to sell it to you at far lower cost than in the shops. NB you do not need new compost to grow salads. As long as you add fertiliser, you can successfully re-use old compost.
The best place to source low cost seeds is at local seed swaps. Large packs of mixed salad leaves are often better value and a good way of learning about new leaves. You can grow many micro greens including pea shoots, coriander, dill, fennel, broad bean shoots, mustard, fenugreek and chick pea shoots from the seeds sold for cooking in health food shops and supermarkets (test a few first for germination before sowing a large batch).
Worm compost is a good fertiliser for salads – mix in a few handfuls to rejuvenate your old compost each time you sow a new batch of salads. Buying a large tub of chicken manure pellets is more of an investment but a cost effective one in the long run. One bucket will be enough for hundreds of trays of salad. High in nitrogen, it’s the perfect fertiliser for salads.
