The short answer: plenty. July is one of the best months of the Irish year for sowing quick crops and it's also the time to sow for winter, when you'll be glad you did. If you haven't started growing yet this year, July is a perfectly reasonable time to begin.
There's a common idea that July is too late, that the growing season is already over and you've missed your window. In Ireland, that simply isn't true. The soil is warm, the days are still long and a whole range of seeds will germinate quickly and reliably. Some of the most child friendly growing projects of the year happen in July.
Here's exactly what to plant in July in Ireland, with honest advice on what to expect and what works particularly well for children.
What's happening in the Irish garden in July
July in Ireland is peak growing season. If you planted in spring, you're now harvesting tomatoes, beans, courgettes, potatoes and soft fruit. While you're pulling things up at one end of the garden, there's still plenty going in at the other. The ground is as warm as it gets all year, which means seeds germinate fast. Some crops that took three weeks to sprout in April will be up in seven days in July.
The flip side is that July is also the month when the season starts to turn. You're sowing now for what you'll be eating in September, October and through the winter. The two things can happen at the same time, pulling up radishes you sowed last week while putting in kale that won't be ready until February.
That rhythm is one of the things children find most surprising about growing, that the garden is always looking forward as well as delivering now.
No garden needed for any of the July sowings below. Radishes, salad leaves, spring onions, nasturtiums and coriander all grow beautifully in pots on a windowsill or balcony. Kale and calendula are happy in larger pots outside. Everything here works without outdoor space.

The best July crops to grow with children
Not everything in that list is equally child-friendly. Here's where to focus your energy if you're growing with children aged 3–9.
Radishes: The one to start with today
If you do nothing else in July, sow radishes. They're the fastest growing crop you can grow in Ireland and children can go from sowing to eating in three to four weeks. The germination is dramatic (big seedlings appear within days), the pulling up moment is enormously satisfying, and eating something you grew yourself the same afternoon feels like magic.
Sow directly into a pot or straight into the ground, 1cm deep, scattered loosely. No thinning needed if you're growing for salads. Just scatter, water, wait and pull.
Nasturtiums: The edible flower
Nasturtiums are one of the great overlooked July crops. They grow fast from large seeds that children can handle easily, they flower in cheerful orange and yellow within five or six weeks, and both the flowers and the young leaves are edible. Children find it deeply pleasing to eat something that looks like a decoration.
Sow directly into a pot or a sunny patch of ground. They're almost impossible to kill and they'll attract pollinators for the rest of the summer.
Lettuce and salad leaves: The 'cut and come again' crop
Scatter salad leaf seeds into a pot or a window box in July and you'll be cutting leaves within four to six weeks. The 'cut and come again' variety means the more you harvest, the more grows back. Children quickly understand this and take great ownership of a salad tray that is genuinely theirs to tend and harvest.
Keep the pot out of full afternoon sun in July as salad prefers a little shade in hot weather, which makes it ideal for a north or east-facing windowsill.
Calendula (Pot marigold): cheerful and useful
Calendula is one of the friendliest flowers you can sow with children. The seeds are large and easy to handle, the plants flower quickly in bright orange and yellow, the flowers attract bees and butterflies, and the petals are edible. You can scatter them in salads or freeze them in ice cubes for a beautiful and slightly astonishing drink.
Sow directly into a pot outside. They'll flower from September onwards and will often continue into November in mild Irish autumns.
Kale is worth sowing in July even if it feels early to think about winter. Start it in a small pot now, plant it out in August and it will be producing through autumn and right through to March, when very little else is growing. It's the most reliable winter crop in the Irish climate and children who sow it in July are often surprised to be harvesting the same plant six months later.
Sowing for winter: Why July is actually the right time
This is the part most people miss. July feels like the height of summer, but some of the most important sowings of the year happen now precisely because the plants need time to establish before winter.
Purple sprouting broccoli is the classic example. Sow it now in a small pot, plant it out in August and it will produce shoots from February through April. These are the leanest months of the growing year, when almost nothing else is ready. It takes patience, but it's the kind of growing project that teaches children something real about how the natural world works.
Kale follows the same logic. Sow in July, harvest from October through March. It gets sweeter after frost, one of those counterintuitive facts children tend to remember.
Spring cabbage sown in July or early August will produce hearts from March the following year. Not a quick win, but worth it.
What to harvest in July
If you planted in spring, July is your reward month. Here's what should be ready:
-
Tomatoes: The first fruits should be ripening now. Check daily.
-
Courgettes: Pick small, around 15cm, for best flavour. They grow fast in July! Check every two days or you'll end up with marrows.
-
French and runner beans: Pick regularly to keep the plant producing.
-
Peas: Any still on the plant from a spring sowing should be picked now before they toughen.
-
Potatoes: First earlies planted in March should be ready. Dig one plant carefully to check.
-
Soft fruit: Strawberries, raspberries, blackcurrants. Peak season.
-
Salad leaves: If you sowed in May or June, you should be cutting these now.
July is genuinely one of the most abundant months of the Irish growing year. If the garden or pots feel overwhelming right now, that's a good sign as it means things are growing well.
July growing tips for Irish conditions
Water pots every day in warm spells
Pots dry out much faster than garden soil in July. If the weather is warm and dry, pots may need watering morning and evening. The test is simple, push a finger into the compost. If the top 2cm is dry, water thoroughly. If it's still damp, leave it another few hours.
Don't sow beetroot after mid-July
Beetroot needs around 10–12 weeks to mature. Sown after mid-July in Ireland, it will be racing against the first frosts of autumn. Sow now or leave it until next year.
Carrots need to go in early July
Carrots need 10–14 weeks to mature and dislike transplanting, they must be sown directly where they'll grow. A July sowing gives them just enough time to produce baby carrots before October. Sow in a deep pot of loose, stone-free compost for the best results without a garden.
Shade matters more in July than any other month
Lettuce, spinach and coriander all bolt (flower prematurely and turn bitter) in sustained heat. In July, give them a spot that gets morning sun but afternoon shade. East or north-facing windowsills are ideal. This is particularly relevant for indoor and balcony growers.
Start growing this month with Little Sprouts
The Little Sprouts Garden Box is a monthly nature subscription for Irish children aged 3–9. Every month we send seeds chosen for the Irish season, peat-free compost coins, an illustrated Irish folklore story, a seasonal craft and a recipe, everything your child needs to grow something real, with no garden required.
Frequently asked questions
Is it too late to plant vegetables in July in Ireland?
No. July is an excellent time to sow fast-growing crops like radishes, lettuce, spring onions and spinach, all of which will produce a harvest before autumn. It's also the right time to sow kale and purple sprouting broccoli for winter and spring harvests. The soil is warm and germination is quick, some seeds that took three weeks to sprout in April will be up in a week in July.
What grows fastest in July in Ireland?
Radishes are the fastest crop you can grow in Ireland in July, from sowing to eating in three to four weeks. Salad leaves and spring onions follow at around four to six weeks. Nasturtiums flower within five to six weeks of sowing. All four are ideal for children because the wait is short enough to stay interesting.
Can I grow vegetables in pots in July in Ireland?
Yes — July is one of the best months for container growing in Ireland. The warm soil temperature means seeds germinate quickly even in pots. Radishes, lettuce, spring onions, nasturtiums, coriander and calendula all grow well in pots or window boxes. Kale grows happily in a large pot outside. No garden is needed for any of these crops.
What should I sow in July for a winter harvest in Ireland?
Kale is the most reliable winter crop to sow in July — it will produce leaves from October right through to March and gets sweeter after frost. Purple sprouting broccoli sown in July and planted out in August will produce shoots in February and March, when very little else is growing. Spring cabbage sown in late July or early August will produce hearts the following March.
What flowers can I plant in July in Ireland?
Nasturtiums and calendula are the best flowers to sow in July for colour and interest this year — both will flower within six to eight weeks and continue until autumn frosts. Foxgloves sown in July will flower the following summer. Cornflowers sown now will flower in late summer if the weather stays mild.
Can I still sow carrots in July in Ireland?
Yes, but only in early July. Carrots need 10–14 weeks to mature and must be sown directly into the ground or a deep pot rather than transplanted. An early July sowing gives them just enough time to produce baby carrots before October frosts become a risk. Sow in a deep container of loose, stone-free compost for the best results without a garden.
