Herbs are really so easy to grow. As a bonus, picked fresh they add an extra special zest to food that can't be achieved with dried versions. The beauty of growing your own is that you can keep a tray of parsley, mint, chervil, coriander, sage and thyme on your windowsill. This means you don't even have to go outside in the rain to pick what you need!
One of the easiest ways to grow your herbs is to take a Compact Rapid Rootrainer tray, fill it with good multipurpose moist compost and sow your seeds into the cells, cover with the propagating lid and leave for about a fortnight to germinate.
Once the seedlings begin to emerge the tray can then be placed on a windowsill where it gets adequate light. As the plants grow the lid can then be taken off and used as a drip tray.
Remember that herbs do not tolerate north facing windows. They prefer a window that get at least 4 hours of direct sunshine per day.
Without a plentiful source of light most indoor herbs will slow down or even stop growing. If you find this happening you should reduce picking as well as reducing the watering. Make sure the indoor temperature is not in excess of 65 degrees until plant growth restarts.
It must also be remembered that not every herb likes living indoors.
Harvesting & Resowing
Herbs like coriander, cress and dill are annuals which when harvested and cut need to be re-sown in order to produce a continuous crop. So it is a good idea to keep 3 trays of these herbs at different stages for a continuous supply.
Herbs that are grown indoors should be clipped or have leaves picked regularly to encourage new growth. Remember that potted herbs dry out more quickly than those in the open ground, although if you are using Rootrainers the structure of the cell encourages a maximization of all water to the roots.
Herbs with large soft leaves such as basil need a fine spray to humidify the air on hot days. Indoor plants should be fed every 2 weeks with a liquid fertilizer to help maintain vigorous growth.
