To beat a summer glut, sow little and often. Stagger small sowings of fast crops like lettuce, beans and radish every week or two. Pick cut-and-come-again greens, beans and zucchini regularly to keep them cropping. Freeze, share or pickle any surplus, and sow long-season crops like tomatoes mostly once.
Most summer gardens swing between feast and famine: nothing for weeks, then more zucchini than anyone can eat. A few simple habits even that out.
Beating the glut is mostly about timing and picking, not growing more. This guide covers how to keep a steady harvest coming, and what to do with the surplus when it arrives anyway.
What causes a summer glut, and why does steady beat sudden?
A glut happens when a whole crop matures at once, which is exactly what one big sowing tends to do. Sow a whole row of lettuce at once and it is all ready in the same fortnight.
Steady cropping is easier to use, share and enjoy. It also keeps the kitchen interested, rather than facing the tenth zucchini of the week. The goal is a trickle, not a flood.
How does succession sowing keep the harvest coming?
Succession sowing means staggering small sowings of the same crop so they mature in turn. Rather than sowing everything at once, sow a little and often through the season.
Sow quick salads and radishes in very small batches every week or two, and sow bush beans every two to three weeks where the season is long enough. In hot spells, swap standard lettuce and radish for heat-tolerant salad leaves, basil or other warm-season greens, with some afternoon shade and steady water.
A few tender herbs, such as basil, also reward repeat sowing. You can browse a range of vegetable seeds and keep a few packets on the go through summer.
Which crops should you sow again and again, and which once?
Fast crops are the ones worth sowing little and often: lettuce and salad leaves, radish, rocket, bush beans and basil. Beetroot, carrots and spring onions can also go in as smaller batches, though they take longer to mature.
Long-season crops are usually best sown once per main season. Tomatoes, capsicums, chillies and eggplant take months to crop and then keep producing for weeks. A mix of early and late tomato varieties can spread ripening a little, though repeat sowing adds less.
How does regular picking keep plants producing?
Many summer crops crop better when you keep removing the young pods or fruit. Frequent picking is half the secret to a long harvest.
Beans can give several flushes if you pick them young and often, while letting pods mature on the plant can slow it down. Zucchini and cucumbers are similar: harvest them young and small, and cut often to keep them coming.
Leafy greens like loose-leaf lettuce, silverbeet and kale work as cut-and-come-again crops. Pick the outer leaves and leave the centre to grow, and a regular liquid feed such as a fish and seaweed blend can help keep them going.
What can you do when you still get a glut?
Even with good timing, summer will sometimes hand you a flood, so have a plan. Sharing with neighbours, workmates or a local food bank is the simplest and most generous option.
For storage, beans, leafy greens, sweet corn and chopped zucchini freeze well for cooked dishes after a brief blanch. Cucumbers can become quick refrigerator pickles. Tender salad leaves are usually better eaten fresh or shared.
Home preserving of low-acid vegetables needs real care. Unacidified low-acid vegetables are not suitable for water-bath bottling. Vegetables packed in oil need proper acidification and refrigeration. Use only tested recipes and methods, and read the food-safety advice from Food Standards Australia New Zealand before bottling.
How does your summer rhythm change by climate zone?
Your sowing rhythm shifts with your climate, though the little-and-often habit holds everywhere. Match the interval to how fast your season is moving.
In the tropical north, around Darwin and Cairns, the dry season is often the main window for succession sowing, with wet-season summer suiting only the toughest crops. Subtropical gardens, around Brisbane, suit short, frequent sowings through the warm months.
In temperate zones, including Sydney, Melbourne and Canberra, a small sowing every fortnight can help keep salads and beans coming, as long as lettuce is shaded in peak heat or swapped for tougher greens. In Mediterranean zones, including Perth, southern WA and Adelaide, dry summers reward steady watering alongside the sowings.
Arid areas, such as Mildura and Alice Springs, work around extreme heat and dry soil, so mulch and water matter as much as timing. Cool and alpine areas, such as the Tasmanian highlands, Ballarat and Orange, have a short window, so start early and stop sowing in time for crops to mature.
A steady summer harvest comes down to sowing little and often, picking regularly, and having a plan for the surplus. Pair it with our guide to summer vegetables that thrive in the heat, and the season stays generous without overwhelming you.
Frequently asked questions
What is succession planting?
Succession planting means staggering small sowings of the same crop so they mature one after another. Instead of one big sowing, you sow a little every week or two for a steady harvest.
How often should I sow for a continuous harvest?
For fast crops like lettuce and radish, sow a small batch every week or two, and sow bush beans every two to three weeks. Adjust the gap to how quickly your crops are growing.
Which vegetables are best for succession sowing?
Quick crops: lettuce and salad leaves, radish, rocket, bush beans and basil. Beetroot, carrots and spring onions also suit smaller batches. Long-season crops like tomatoes and chillies are better sown once.
How do I keep beans and zucchini producing?
Pick them young and often. Beans can give several flushes if you keep picking, and zucchini crop best when cut small and harvested regularly, before they turn into marrows.
What can I do with a glut of vegetables?
Share the surplus, freeze suitable crops after a quick blanch, or make refrigerator pickles. For bottling low-acid vegetables, use only tested recipes and safe methods.
Is it safe to bottle vegetables at home?
Only with care. Low-acid vegetables can carry a botulism risk if bottled in oil or by water bath without proper acidification, so follow tested recipes and the food-safety guidance from Food Standards Australia New Zealand.
