At Jekka’s we love growing plants and still, after nearly 40 years, find it magical to raise plants from seeds. We have written numerous blogs on growing from seeds, including:
- Jekka's 5 top tips for sowing herb seeds;
- Jekka's guide to growing vegetable seeds indoors and directly outdoors; and
- Jekka's tips on sowing your winter culinary herbs.
However, it is also vitally important to collect and harvest your seeds. This is becoming even more true as not only is it becoming difficult to import seeds into the UK but also the threat of climate change and the associated extreme weather events such as fires is putting seed availability at risk.
Therefore, by collecting, storing, drying and sometimes sharing your seeds, you are helping protect the future of plants.
Jekka’s guide to harvesting herb seeds
Jekka's top tip for harvesting seed is to collect the seeds after midday. This is when all traces of the mornings dew have evaporated and the seed heads are dry. Choose vigorous healthy plants and harvest when most of the seed appear to be ripe.
After cutting the seed heads, allow them to dry out naturally in a warm dry place with good air circulation. A sunny windowsill is idea, but the kitchen is the worst place due to humidity and moisture.
To allow the seed heads to dry out thoroughly, let them lie loosely in open cardboard boxes or in open paper bags. Either write on the cardboard box or the paper bag the name and date of the seed collected so you can remember which is which when it comes to cleaning.
When the seeds are cleaned, we store them in paper envelopes onto which we will have written their botanical name and date of collection. We highly recommend using paper envelopes as this will help to protect your seeds from sweating and then rotting. The envelopes should then be put in a container to protect them from rodents, and stored in a cool room or garage, not in a greenhouse.
Start sowing herbs this Autumn
Autumn is the perfect time to sow culinary herbs to produce a winter crop because the soil is still warm and the pest and diseases that might have been present earlier in the year, such as carrot fly, have gone away. Autumn herbs will enable you to add fresh herb flavours to your winter meals, soups and salads. Check out Jekka's tips on sowing your winter culinary herbs.
Especially for Autumn, see Jekka's Grow at Home Autumn Herb Kit that contains all you need to start growing this autumn.
