In her latest seasonal blog on herbs, Stephanie Hafferty celebrates the flavours and fragrances of summer, from sowing basil seeds to making the most of fresh harvests from the kitchen:
The joy of basil and other herbs - sowing to eating!
Summer is my favourite season in the herb growing calendar, because it is the time when basil thrives. Here in the UK, our cool damp climate is not ideal for growing this fragrant, flavoursome, warmth and sun-loving herb during the rest of the year.
This year I am growing 16 or so varieties of basil, including lime, lemon, lettuce leaf, Thai, red and liquorice, as well as the more familiar classic Italian basil. The choice of seed available now is wonderful.
How to grow basil
I like to sow basil into a seed tray, and then prick out as many seedlings as I need. Basil needs warmth to germinate, so this way I am able to grow up to 20 different kinds of seedling in one tray, saving space on the heat mat.
Fill a seed tray with Dalefoot Wool Compost for Seeds and lightly water. Make 9-10 shallow grooves in rows across the width of the tray with your fingers. This is where you’ll sow the seeds.
Use old seed labels to make a ‘barrier’ down the middle of the length of the seed tray. This doubles the number of seed varieties you can sow.
Sprinkle the seeds in each groove, labelling with the variety as you go. Sprinkle some more compost on the top, just a light layer, and place on a heat mat or somewhere warm and sunny.
When the seedlings have germinated, prick out all that you want into module trays filled with seed compost. Then, place the tray with leftover seedlings back in a warm sunny place, and leave them to grow into microleaves: two crops from one tray. Cut when large enough and enjoy - a taste of what is to come.
Be careful not to over-water. Basil won’t enjoy being waterlogged, so keep the compost moist but don’t over water.
When the plants are big enough, 6-10cm tall, and after danger of frost has passed, plant out using a dibber in the ground, or pot on into larger pots. In much of the UK basil grows better undercover, in a greenhouse, cloche or polytunnel.
I enjoy the mindfulness of pricking out seedlings, but it is not for everyone. An alternative is to fill a module tray with seed compost and sow 2-3 basil seeds per module. Thin to 1 seedling when large enough to handle.
Try growing lemongrass
To accompany Thai basil, grow lemongrass, a popular ingredient in Thai cuisine. It needs a similar start in life to basil.
Fill a module tray or several small pots with Dalefoot Wool Compost for Seeds, lightly water and then sprinkle a pinch of lemongrass seeds on each module. Cover with a light sprinkling of compost and place somewhere warm, light and frost free to germinate.
Plant out when 8-10 cm tall in the ground (undercover is best in most of the UK) or in pots in a sunny location.
Lemongrass is easy to over winter if grown in pots. Bring the pots inside in the autumn and place on a sunny windowsill.
Lemon Verbena: the queen of lemon-scented herbs
If I had to choose just one herb to grow, it would be lemon verbena (Aloysia citrodora). This perennial herb has intensively scented and flavoured leaves. Crush a leaf and inhale the fragrance for a hit of bright lemon sherbet.
I mainly grow it to make herbal tea, delicious dry and fresh. It is a very versatile herb. Use it to make cordial, syrup, a liqueur (infused in gin or vodka), sugar, salt, infused in vinegar, and more.
Buy plants from a good herb supplier which grows in peat free compost. You can also propagate it from cuttings.
Lemon verbena is a really easy herb to grow. It is happy in most soils as long as they are well drained, but does need a sunny spot. It is mostly pest and disease free, and ideal for growing in urban courtyards or balconies, as well as in gardens.
I grow all of my lemon verbena (I have five plants!) in pots, so that they can come outside in late spring and then return undercover (inside the polytunnel) in the late autumn. Very cold, wet winters can kill the plant, so I take this precaution.
It is very happy in Dalefoot Wool Compost for Potting (the red bag). Lemon verbena doesn’t like being waterlogged, so make sure it’s not sitting in a tray of water, and that the pot can drain as needed.
Lemon verbena is one of the easiest herbs to dry. Simply cut bunches, then hang in an airy spot. Store the dried leaves in clean, dry jars in a cool, dark place.
Steph’s recipes for basil
Each variety of basil offers something special in the kitchen, especially if you enjoy trying out different international cuisines. Large lettuce leaf basil has a wonderful typical basil flavour and can be used just as you would Italian basil in pesto, sauces, salads etc. Where it really shines is as a one-bite cup or wrap.
Lettuce leaf basil one-bite cups
A wonderful way of making leftover bits and bobs in the fridge into something delightful.
Finely chop raw summer vegetables and whatever else you fancy: cooked chicken, tofu, mushroom, etc.
Place a teaspoonful in each basil leaf.
Add a little sauce. I like soy sauce, chilli and lime for a spicy kick. Mayo, peanut sauce, hummus or your favourite salad dressing are good too.
To serve, leave the little wraps open, like leafy cups.
To eat, pick up the filled leaf, fold the sides in and pop into your mouth. Oh yum!
Make the most of basil flowers
To keep basil cropping and producing masses of fragrant leaves, it is important to pinch out the basil flowers. Otherwise, the basil will “think” that it is time to produce seeds, focusing on that stage of its life cycle.
Basil flowers are delicious. They taste like a lighter version of the leaves. Add to salads for a tasty, pretty garnish, or use to make salad dressings by infusing in oil.
Basil Flower Oil
Place the basil flowers to half fill a clean jar. Pour over a light oil, such as olive oil, ensuring the leaves are completely submerged.
Leave in a cool place out of direct sun for a week to infuse. Strain through a sieve lined with muslin, discard the basil flowers into the compost heap, and pour the oil into a bottle.
Use within a month.
