How to grow dill: quick tips to follow
- Dill is easy to grow and will self-seed if you leave some seed heads on at the end of summer.
- Do not allow the soil or compost around your dill plants to dry out.
- Water dill regularly, especially during hot, dry summers, but do not over water.
- Hoe around plants to prevent weeds from smothering the dill.
- Foliage is ready for picking around two months after sowing.
- Support plants with canes or twiggy sticks as they have a tendency to blow over.
- Harvest the seeds at the end of the season for cooking.
What is the best way to grow dill?
Dill does best from direct sowing, as it doesn’t like having its roots disturbed. This means planting the seeds where they’re going to grow in your kitchen garden ideas, either in the ground or a pot.
The best time to direct sow is in early spring. Cover the soil surface with fleece to warm it up and encourage the seeds to grow.
Start picking once the plants are about 15cm tall and have a decent amount of leaves on them. Every month, pop a few more seeds into any remaining spaces to ensure a continuous supply.
How to sow dill seeds
- Sow in full sun, where you want your dill to grow, from mid spring onwards, in drills 6mm deep.
- Make sure the soil is well prepared. Keep well watered in dry weather if you want to make sure the process of how to grow dill is a smooth one.
- It's also easy to start an early crop of dill under cover, either indoors, in a cold frame or in the best mini greenhouse. The way to do it is by planting the seeds in plugs, which can be transplanted into the ground in blocks of soil leaving the roots intact. This should be done only when there is no risk of frost.
How to grow dill in a container
Like most herbs, dill can also be sown directly in large pots as part of your container gardening ideas. Position it by the kitchen door and sow successionally for a continuous supply of fresh leaves through summer.
- The most important thing to get right is the depth of your container. Dill grows a long tap root, and any garden planter ideas that are shallower than 12in (30cm) won’t provide enough space for it to flourish.
- Choose a compact variety. Fill the pot with compost free potting mix, making sure there are drainage holes in the bottom as dill prefers well-drained soil. Sprinkle a few seeds on the surface, then cover them with a very light layer of potting mix.
- Dill will thrive in a pot, provided you keep watering plants every couple of days and don’t let the compost dry out.
- In early spring, keep your pot indoors on a sunny windowsill or in a greenhouse. Keep the soil moist by misting it regularly. Once the seedlings are big enough to handle, thin to one or two per pot and care for them as you would if you were growing them outdoors.
Is dill easy to grow?
Sow dill where you want it to grow and it will propagate if you allow it to self-seed, which it does readily. This is key to how to grow dill as it means you can multiply your stock with ease.
It’s not difficult to end up with spectacularly huge plants that add an eye-catching sculptural element to garden borders or raised garden bed ideas as long as you sow the seeds early enough in the season (March to July).
Even if you sow dill seeds later in the season, as long as autumn is a warm one the plants will still have time to self seed. Mature plants rarely need watering either as they send down long tap roots to moisture in the soil.
Does dill need full sun?
Dill is a native of the Mediterranean region where it's common to see fields of it growing. This means it does best if it gets plenty of sunshine and is in a sheltered position.
Want to add it your own Mediterranean garden ideas? The area you choose to plant it should be protected from high wind as the stalks of dill are thin and hollow. It likes lots of light to germinate too, while regular watering early on ensures healthy plants.
What month do you plant dill?
It's essential to plant it at the right time of year if you want to learn how to grow dill successfully. When to do it depends on where you live as well as how the weather's warming up, but as a general rule it should be from mid-spring onwards.
Dill is tender so plant out as soon as any risk of frost has passed. If there's any doubt, use horticultural fleece to protect any young plantings.
How to care for dill
- When seedlings are established and sturdy enough to handle, thin them out to 6-8in (15-20cm) apart. Use any thinnings in the kitchen, where they make a great addition to the salad bowl and tasty side dishes for your BBQ recipes.
- Keep plants well-watered, particularly during hot, dry weather.
- Keep the area around your dill plants weed-free to stop any competition for water and nutrients. There's lots of tips on how to get rid of weeds in our guide.
- Plants may need additional support from canes or twigs, as strong winds can cause them to flop over. Staking is key when learning how to grow dill well and keeping your crop in the best possible shape.
Should I feed my dill plants?
Fertilizer is not so important when it comes to how to grow dill. It grows best in a well drained, slightly acidic soil that's rich in organic matter. As with most herbs, dill does not require frequent fertilizing. All that's needed is an occasional liquid feed of balanced fertilizer to give the plant a boost during the growing season.
What problems affect dill?
You're generally in for a trouble-free time when it comes to how to grow dill, but there are a few things to watch out for.
- Plants can occasionally go moldy. The key to avoiding this is to add some sharp sand or grit to the soil before planting. Also make sure you choose a sunny spot with enough space for air to circulate around each plant.
- Greenfly can sometimes be an issue. If you spot any on your plant, you can use your finger and thumb to squash any greenfly you see.
- Watch out for slugs, which are partial to young dill leaves. Some of the easiest options for how to get rid of slugs include using beer traps, eggshell barriers or copper tape as a deterrent.
- Dill plants can occasionally bolt. Choose bolt-resistant varieties wherever possible, and sow seeds at the correct time for best results.
How to harvest dill
Getting the best out of your crop is key to how to grow dill successfully. Cut the leaves as required during spring and summer. Picking young leaves regularly will help to keep plants productive and delay flowering.
The leaves can be used fresh, or can be frozen or dried for later use if you find yourself with a glut. Nothing beats having a supply of homegrown herbs in the depths of winter.
To dry dill leaves, hang up sprigs in a dark, well-ventilated place for a few weeks. When fully dried, strip the leaves from the stems and store in an air-tight jar.
Gather seeds in late summer when they start to ripen and turn golden. Cut stems with the seed heads intact. Spread them on newspaper until the seeds are dry enough to shake loose easily. Store the seeds in an air-tight container or jar, for using whole or ground as needed.
