Growing and Using Culinary Herbs part 1 is from August 2025.

Let’s look at where to get herb seeds and plants.

Richters in Goodwood is one of the largest herb growers in North America. You can learn a lot from just reading their extensive catalogue.  Their greenhouses are well worth a visit and Goodwood is only about an hour’s drive from Peterborough. They carry dried herbs as well as plants and seeds. Richters is open year round; check their website for days and hours. Many local nurseries carry a good selection of seeds and plants.

Start your seeds under lights in February/March e.g. basil, sage, thyme, lovage and harden them off slowly. You can direct seed outdoors once the soil is warm enough. Parsley seeds have a hard coating and it is a good idea to soak them overnight first. You will need to sow coriander seeds every month if you want a continuous supply of cilantro leaves.

Many herbs can be successfully propagated by taking hardwood cuttings. Rosemary works well this way if you take the cuttings in mid summer to mid fall. Take the cutting just below a node, dip it in hormone powder and insert several cuttings into a soilless mix. Cover with a plastic bag and open every few days to clear some of the moisture. They will root in 4 – 6 weeks.

Lots of herbs benefit from dividing in the spring. Good candidates are parsley, chives, lemon balm, oregano and thymes. Woody herbs such as sage and thymes can be layered by pegging a stem into the soil. Check for roots in a month or so and once rooted they can be cut from the mother plant and replanted.

Many perennial herbs such as lavender, hyssop and oregano can be lightly pruned in the fall and harder in the spring. I don’t prune sage until after it has finished flowering as the bees  love the purple flowers.

Picking the growing tips frequently encourages fresh new growth and gives you lots of herbs for cooking. Lovage and sorrel should be cut back hard after flowering to encourage new bushy growth. The best time to harvest for peak flavour is in the morning before the essential oils have evaporated. Leaves should be young and before the plant flowers.

There are several options to preserve your herbs for culinary use. Herbs such as basil, chives, chervil and parsley work well finely chopped and put in ice cube trays with a little olive oil or water. Freeze and use them to pop into stews and soups.

If you have a warm, dark, well ventilated space , tie the herbs loosely and hang upside down. Larger leaves can be dried on a mesh screen. Dehydrators are great or you can use a microwave on a low setting. Once thoroughly dry, store in labelled glass or ceramic containers away from the light.

Garlic dill pickles are easy to make and make great gifts. Pestos and vinegars are a great way to use your herbs. Vinegars are simple  to make and tarragon, thyme and basil are especially good and will last a long time. I use herbal vinegars for salad dressings and to pep up soups and stews.

Herbal butters are straight forward  to make but give a real lift to vegetables, grilled meat, stuffings, or pasta. Finely chop 4 to 5 tablespoons of fresh herbs to 8 oz of softened butter and blend well. Place in cling film and form into a long rectangle. Chill, cut into lengths and wrap tightly in foil, label and freeze. You can then slice off any amount that you want.

I have just touched on the many wonderful culinary herbs that you can grow. Have fun, experiment and enjoy the wonderful smells and tastes of fresh herbs.
