Harvesting limes at the right moment is the difference between a crop that tastes superb and one that is tough, sour or bland. Pick too early and you lose flavour; pick too late and you lose texture, and the plant slows down. This guide covers when to harvest limes — the signs that tell you when one is ready, how to pick it without damaging the plant, the best time of day to harvest, how often to check, what happens if fruit is left too long, and how to store the harvest, both for a few days and for months. The timing below uses the published range for this crop, 1095–1825 days to maturity, which varies by variety, climate and soil, so treat it as a guide and judge each plant by what you can see and feel.
Limes are a fruit in the Rutaceae family, with tender cold tolerance and moderate water needs. They need full sun and can be started indoors or sown direct. Knowing those basics helps you judge harvest time, because a plant that has been watered evenly and grown in the right conditions ripens evenly, while a stressed plant ripens unevenly and often disappoints. Keep a simple note of when you planted and when you first picked — after one season you will have a record far more useful than any general guide. As with all the timings in this guide, these are broad published ranges, not exact dates for your garden, so check your local extension service for your area.

Signs that limes are ready to pick
The best harvest decisions are made with your eyes and hands, not with the calendar. Days to maturity is a useful starting point, but weather, variety and watering all shift it, so learn the signs for this crop and check plants regularly once the harvest window opens. For limes, the signs are:
- Deep green, with a slight yellowing: A ripe lime is a deep, even green, sometimes with the faintest hint of yellow at the blossom end. A lime that is still pale or bright grass-green is usually not ready, while one that has turned clearly yellow is overripe.
- A slight give when squeezed gently: Hold the lime and squeeze it very gently. A ripe lime yields slightly and feels a little springy, while an unripe one feels rock-hard. A lime that feels soft or spongy is overripe and may be dry inside.
- Glossy, smooth skin: Ripe limes develop smooth, glossy skin. Dull, rough or very thick-looking skin usually means the fruit is still young, while wrinkled skin means it has been left too long.
- Heavy for its size: Lift the lime. A ripe lime feels heavy for its size, because it is full of juice. A light lime for its size is usually underripe or has been short of water.
- Easy to pick: A ripe lime comes away with a gentle twist or a snip of the stem. If you have to pull hard, the fruit is not ready — leave it for another week or two and test again.
The single most useful habit is to check plants every day or two once the first fruit starts to ripen, and to pick a test fruit if you are unsure. One test tells you more than a week of guessing. Taste it, look at it, feel it — and then pick the rest of the row at the same stage. If the test fruit is not ready, leave the plant alone for a few days and test again. Over a season you will learn to read this crop at a glance, and harvesting will become quick and confident.
How to pick limes without damaging the plant
Snip each lime with clean secateurs, leaving a short piece of stem attached, and lay it gently in a basket — do not pull limes off the tree, which tears the branch and can damage next year's fruiting wood. Wear gloves if the tree is thorny, and pick in the cool of the morning when the fruit is firm. Pick limes as you need them rather than stripping the tree, because limes hold well on the tree for weeks once ripe and you can harvest over a long season. Take the largest, deepest-green fruit first and leave smaller fruit to size up.
Whatever the crop, the rules are the same: use clean, sharp tools, support the plant while you pick, pick in the cool of the morning when the produce is crisp, and never yank or tear. A clean cut heals fast; a tear leaves an open wound that disease can enter, and a damaged plant produces less for the rest of the season. Keep your tools clean between plants, wash your hands before handling food, and put harvested produce in a clean basket or trug rather than on the soil, where it picks up dirt and pests.
Best time of day and how often to pick
Pick in the morning, after the dew has dried but before the heat of the day, when the produce is cool, crisp and full of water. Produce picked in the heat of the day wilts fast and does not keep as well. Check plants every day or two once fruit starts ripening, and pick each fruit as it ripens. Regular picking encourages the plant to set and ripen more fruit, and in a frost-free climate like Zone 13 a healthy plant can keep producing for months.
Regular picking is not just about getting the best flavour — it is also how you keep the plant producing. Most fruiting plants slow down or stop setting new fruit when mature fruit is left hanging, because the plant has done its job. Picking regularly tells the plant to keep flowering, and in a frost-free climate that can mean weeks of extra harvests from the same plants.
What happens if limes are left too long
Left too long, limes turn yellow, grow thick-skinned and dry inside, lose their sharp juice, and eventually drop to the ground where they rot. Overripe fruit left on the tree also draws pests and can slow the tree down. Because limes hold well on the tree, the risk is not a sudden spoiling but a slow drying out — pick fruit within a few weeks of ripening and do not leave the whole crop hanging for months.
The cost of leaving produce too long is not just one spoiled fruit. An over-mature fruit left on the plant can slow the whole plant down, attract pests that then move on to healthy fruit, and spread disease from rotting tissue. A daily or every-other-day check is the cheapest insurance in the garden: it takes a few minutes, and it catches problems while they are still small. If you do find over-mature fruit, remove it promptly — compost it if it is diseased, and use it in cooking if it is simply past its best.
How to store limes
Limes keep at cool room temperature for a week or so, and for several weeks in the fridge, where they stay juicier for longer. Store them loose or in a perforated bag, and check them regularly, removing any that soften, yellow or spot. For a glut, freeze lime juice in ice-cube trays and zest in small bags, or use the juice in cooking and drinks straight away. A lime that has gone yellow and soft is best used in cooking rather than stored.
A good rule for storage is to sort the harvest as you pick it: the best produce keeps longest, so store the firm, unblemished fruit and eat the damaged or softest pieces first. Check stored produce regularly and remove anything that softens or spoils, because one bad piece can spoil the rest. Label anything you freeze or preserve with the crop and the date, so you know what you have and when to use it.
Succession sowing and continuous harvest
Limes are evergreen trees, so succession means picking little and often over a long season rather than sowing again. In warm climates a lime tree can fruit for much of the year, with a main crop and smaller flushes in between. Because the published range for this crop is 1095–1825 days to maturity, a young tree needs several seasons before it carries a full crop — be patient in the first years and let the tree build a strong frame. Keep notes on when your tree crops heaviest, so you can plan preserving and cooking around it.
Succession is the answer to the two most common harvest problems: a glut followed by nothing, and a crop that finishes all at once. Plant a little, often, rather than a lot at once, and you will have a steady supply instead of a feast and a famine. Keep notes on what you planted and when, so you can repeat the timing that worked and adjust the timing that did not.
Common harvesting mistakes
- Pulling limes off the tree instead of snipping them, which tears the branch.
- Waiting for limes to turn yellow — yellow means overripe, not ripe.
- Picking by colour alone, before the fruit has filled with juice.
- Stripping the whole tree at once, instead of picking as needed over a long season.
Most harvesting mistakes come from the same place: guessing instead of looking, and leaving the garden alone for a week at the critical moment. A short daily check, a test fruit when you are unsure, and picking little and often will avoid nearly all of them.
Frequently asked questions
How do I know when a lime is ripe?
Look for a deep, even green with at most a faint hint of yellow, a slight give when squeezed gently, glossy skin, and a heavy feel for its size. Limes take 1095–1825 days to maturity, so use that range as a rough guide and judge each fruit by colour, feel and weight.
Should limes turn yellow before I pick them?
No. A lime that has turned clearly yellow is overripe and will be dry inside. Pick limes while they are deep green and slightly soft, and use yellow ones in cooking straight away.
Will limes ripen after picking?
Limes do not get much juicier once picked, so pick them when they are deep green, slightly soft and heavy. A pale, hard lime will stay dry on the counter.
How long will fresh limes keep?
A week or so at cool room temperature, and several weeks in the fridge. Freeze juice in ice-cube trays and zest in small bags to keep a glut.
Can I grow limes year-round in Zone 13?
Zone 13 is frost-free, so lime trees grow and fruit for a long stretch, and they are one of the best citrus crops for warm climates. The Zone 13 page for limes covers timing in a frost-free climate, and your local extension service can advise on varieties suited to your area.
