This is a well-kept secret, but many herbs don't really like to grow in pots. The idea's great, and a lovely terracotta tub of parsley will look gorgeous on the porch for a few weeks, but most herbs prefer to grow in gardens and, if you want a constant supply
of happy, healthy herbs, it pays to give them a bit of space.
Having said that, a herb garden doesn't need to be huge. What it does need to be is easy to plant, easy to weed, and close to the kitchen. Nobody wants to truck off down the section in the pouring rain to get a handful of something to stuff in the stew. You can buy a raised bed at your garden centre, and that's a really good way to get a head start. Alternatively, you could build one out of railways sleepers, timber, rocks, or concrete blocks. Failing that, simply dig over a patch of earth and plant it.
Some herbs have specific requirements but, generally, free-draining soil, reasonable moisture, fertiliser and a good amount of sunshine will do the trick.
Some are vigorous growers, so don't cram them in. Keep them well-watered and cared for, and harvest regularly to promote new growth. If you'd like to make suggestions, ask questions, agree, disagree, advise, elaborate, comment or berate, please email me at info@gardenpress.net
