August is the busiest month in the Irish garden. Everything is producing at once. From tomatoes finally ripening, beans needing picking every other day and courgettes that can double in size overnight. The jobs list feels long, but most of them take minutes and nearly all of them can be done with children alongside you.
This is also the month when you start looking forward. The harvest is here, but so is the moment to sow for autumn and winter.
Getting both right in August means the growing year doesn't end in September it c,arries on through the cold months with crops that are already established.
Here's what needs doing in the Irish garden this August, in order of priority.
August gardening jobs: The full list
| Job | Why August | Good for kids? |
| Harvest every day | August crops produce faster than any other month. Courgettes left two days become marrows. Beans left a week stop cropping. | ⭐⭐⭐ Children love the daily hunt. Turn it into a game. Who can find the most hidden beans? |
| Water pots morning and evening | Pots dry out rapidly in August warmth. A pot that looks fine at 9am can be bone dry by 3pm. | ⭐⭐ Give children their own watering can. Their pot, their job. |
| Save seeds from your best plants | August is seed saving month. Let one pod dry fully on the plant, collect, dry, store and you have free seeds for next year. | ⭐⭐⭐ Children can create seed packets for each seed type you save! |
| Sow kale and winter greens | These need to go in now to be established before cold weather. Sown in August, they harvest from October through March. | ⭐⭐ A long game growing project that teaches patience beautifully. |
| Sow spring onions and winter salads | Quick crops that will produce before first frosts. Land cress, spinach, lamb's lettuce all go in now. | ⭐⭐ Fast germination keeps children interested. Results visible within days. |
| Plant strawberry runners | Daughter plants sent out by established strawberry plants. Pin them into small pots of compost to root, then plant out. | ⭐⭐⭐ Children can do this almost entirely independently. New plants from old ones is genuinely an exciting experience. |
|
Deadhead flowers |
Removing spent flowers tells the plant to keep producing rather than setting seed. More flowers, longer into autumn. | ⭐ Good job for careful, methodical children. Small scissors, clear instructions. |
| Check for pests on brassicas |
Cabbage white butterflies are active in August. Check the undersides of leaves for yellow eggs and green caterpillars. |
⭐⭐⭐ Children love the detective work. Caterpillar spotting becomes an activity in itself. |
| Clear finished crops | Once a crop is done, clear the bed or pot. Leaving dead material encourages disease. Compost what you can. | ⭐ Useful job for older children (7+). Explain what composting does and how it is food for next year's soil. |
The most important job this month is harvesting every single day
This is not an exaggeration. August crops produce faster than at any other time of the Irish growing year. A courgette that is the right size on Monday can be a marrow by Wednesday. A runner bean that is almost ready on Thursday can be tough and stringy by Saturday.
The rule is simple: if it looks nearly ready, pick it. The plant will produce another one. Leaving crops on the plant too long sends a signal that reproduction is complete and production slows or stops entirely.
For children this is one of the most satisfying jobs of the whole growing year. The daily harvest is a hunt. Lifting leaves to find hidden beans, checking behind the compost to see if a forgotten courgette has appeared, spotting the first tomato that has turned fully red. Build it into the routine and they will ask you for it.
Courgettes are the fastest producers in August. Check every two days at minimum. A courgette left a week becomes a marrow. It's still edible but the plant will slow production significantly. Pick them small, around 15cm, for the best flavour and the most continued cropping.
What to sow in August in Ireland
The sowing jobs in August are all about getting winter crops established before the cold arrives. These go in now so they have time to develop roots and leaves before temperatures drop in October.
Kale: Your most valuable August sowing
Kale sown in August will produce leaves from October right through to March in a normal Irish winter. Sow in a small pot now, plant out in September and you will be harvesting through the coldest months when almost nothing else is growing.
The easiest variety for children is Red Russian Kale as its leaves are softer and less bitter than curly kale, it looks beautiful in the garden and children find the purple veined leaves striking.
Winter salads
Land cress, lamb's lettuce and winter spinach all go in now. These are the fastest August sowings. Land cress can be ready to cut in as little as three weeks in August's warm soil. Sow directly into a pot or a clear patch of ground, scatter thinly, water well. Children can be harvesting their own salad leaves by September.
Spring onions
A late August sowing of spring onions will be ready to pull in October and November. Sow thickly in a pot, no thinning needed, and pull as needed when they are pencil thick. Children love the pulling up moment with spring onions. The small resistance before the plant releases is enormously satisfying at age four.
Do not sow beetroot or carrots after mid-August in Ireland. Both need 10-12 weeks of reasonable growing conditions to mature, and the shortening days and cooling temperatures from September onwards will slow them to a crawl. Leave both until next year's spring planting.
Seed saving: The August job most people forget
August is the best time of year to save seeds from your best plants. It costs nothing, it gives children a direct connection between this year's growing and next year's, and it is one of those activities that feels genuinely meaningful once you understand what you are doing.
How to save seeds with children
Choose the best plant. The one that produced the most, had the biggest fruit, or seemed happiest in your conditions. Leave one pod, one flower head, or one fruit on that plant to dry out completely. Do not pick it. Let it dry on the plant until the pod is brown and papery.
When it is fully dry, pick it carefully with your child. Open it together over a piece of white paper. Tip the seeds out, let them dry for another week in a warm spot, then store in a small paper envelope in a cool dry place. Label it with your child's writing. Include what the seed is, when you saved it and the year.
The following spring, those seeds go back into the ground. The same plant, the same garden, the same hands. That continuity is worth more than any seed packet you can buy.
Which seeds to save in August
-
Beans: Runner, French and climbing beans all produce easy to- ave seeds. Leave one pod to dry completely on the plant.
-
Tomatoes: Squeeze seeds from a ripe fruit onto kitchen paper, rinse, dry and store. Very satisfying and they keep for three to four years.
-
Sunflowers: Let the head dry fully on the plant. Children can pull the seeds out themselves.
-
Nasturtiums: Collect the large seeds as they fall. They self seed freely but saving gives you control over next year's colours.
-
Calendula/marigolds: Let flower heads dry brown on the plant, then collect the curved seeds from inside.
The job that pays off in spring: Strawberry runners
Established strawberry plants send out long stems called runners in summer, with a small plantlet at the end. In August these plantlets are ready to root. Pin them into a small pot of compost using a bent piece of wire or a hairpin, keeping the runner attached to the parent plant. Within three to four weeks the plantlet will have rooted.
Once rooted, cut the runner, lift the new plant and put it in its permanent position. You now have a free strawberry plant that will produce fruit next summer!
Children can do almost every part of this themselves. The pinning-down moment, checking for roots by giving a gentle tug, cutting the runner with small scissors when it's ready. It is one of the most self directed activities of the growing year.
Watering: The job that cannot wait
Containers need watering every day in August, often twice a day during warm spells. The test is simple, push a finger into the compost. If the top 2cm feels dry, water thoroughly until it runs from the bottom of the pot. If it is still damp, leave it another few hours.
Garden beds and borders need less frequent watering but deeper soaking. A thorough water twice a week is better than a light daily sprinkle. Deep watering encourages roots to go down, making plants more resilient.
Children can take full ownership of their own pot. Their pot, their watering can, their responsibility. This is one of the most effective ways to build a genuine growing habit in a young child. Give them something specific that is entirely theirs to care for.

Frequently asked questions
What should I be doing in the garden in August in Ireland?
The most important August jobs are harvesting every day, watering containers morning and evening, sowing kale and winter salads for autumn and winter crops, saving seeds from your best plants, and planting strawberry runners for next year's fruit. August is also the month to clear finished crops and deadhead flowers to keep them producing into September and October.
What can I still plant in August in Ireland?
You can still sow kale, winter spinach, land cress, lamb's lettuce and spring onions in August. All of these will establish before the cold and produce through autumn and winter. Strawberry runners can be rooted and planted out. It is too late to sow tomatoes, courgettes, beans or sweetcorn from seed in August.
Is it too late to grow anything in August in Ireland?
No. August is actually one of the best months to sow hardy crops that will carry you through winter. Kale, spinach, land cress, lamb's lettuce and spring onions all go in now and will produce well into the new year. The key is getting them in the ground before mid-August so they have enough warmth to establish before temperatures drop.
How often should I water my garden in August in Ireland?
Containers need checking daily in August and may need watering twice a day during warm spells. Push a finger into the compost. If the top 2cm is dry, water thoroughly.
Garden beds need a deep soaking twice a week rather than a light sprinkle daily. Mornings are the best time to water as there is less evaporation than midday and foliage has time to dry before evening which reduces disease risk.
How do I save seeds with children in August?
Leave one pod, flower head or fruit on your best plant to dry fully on the plant. Don't pick it early. Once it is brown and papery, collect it with your child, open it over white paper, spread the seeds on kitchen paper to dry for a week, then store in a small paper envelope in a cool dry place. Label with your child's writing. Beans, tomatoes, sunflowers, nasturtiums and calendula are all easy to save in August.
