Sonoma County Fruit Tree Harvesting
Get the Timing Right for Peak Flavor and Quality in the North Bay
At first glance, reaping the abundance of your Sonoma fruit trees appears elementary—simply pick the fruit when it looks good and enjoy. But if you’ve ever cut into a beautiful peach only to find its flesh is rock hard and tasteless, you’ve experienced the result of a too-early harvest. On the other hand, fruit may split or drop if you wait too long, or worse, plant pests will get to it first.
Each fruit variety has specific ripeness indicators, picking windows, and handling requirements that affect both eating quality and storage potential. Sonoma’s microclimates and soil diversity also play a role. It might be the perfect time to harvest tomatoes down the road, while your property’s plants will be ready in a few days.

When to Harvest Different Fruits in Sonoma
Harvesting Peaches, Cherries, and Plums
Stone fruits are particularly challenging because, once picked, they continue ripening but never increase in sugar content. This means that when you’re harvesting peaches or harvesting plums, you must catch them when sugars have fully developed but they aren’t overripe. During peak season, check your trees daily—in warm weather, stone fruits can go from perfect to overripe in 24-48 hours.
Harvesting cherries: Though they are a stone fruit, cherries are renegades and don’t continue ripening once picked. So, you’ll be left with sour fruit that will stay that way if you pluck too early! A ripe cherry should be fully colored and have a slight give when gently squeezed. Another indicator is to try and pick a few—if stems separate easily from the branch with a gentle upward twist, they’re ready.
Harvesting peaches: As their background color shifts from green to cream or yellow, peaches are approaching optimal ripeness. However, harvest timing depends on variety and intended use. Freestones, which are terrific for fresh eating or baking, need slight softening at the stem end, while clingstone types for canning or jams can be picked slightly firmer.
What’s the difference between freestone varieties and clingstone?
Put simply, when the pit pops out cleanly after you cut in half and twist, you’ve got a freestone. As you can imagine, a clingstone is the opposite—the flesh grips the stone and removing it cleanly is almost impossible. For example, cherries are a clingstone, which is why you must eat around the pit.
Excluding cherries, stone fruit harvested at proper ripeness continues developing flavor and softening when left at room temperature for a few days.
- Check daily during peak season as stone fruits can go from perfect to overripe in 24-48 hours during hot Sonoma weather.
- Harvest in the morning after dew dries but before the afternoon heat, when fruit temperatures are coolest and flesh is firmest.
- Use gentle pressure to test firmness near the stem end—fruit should yield slightly but not feel mushy.
- Lift and twist rather than pull straight down, which can damage fruiting spurs.
- Handle carefully as even minor bruising can create entry points for decay organisms and dramatically shorten storage life.
Harvesting Citrus
Citrus fruits are the most forgiving to harvest. Even after reaching maturity, they can remain on the tree for a while without significant quality loss. When to pick lemons, when to pick oranges, and when mandarin oranges are in season depends more on when you want to use them.
Harvesting oranges: These juice favorites don’t continue ripening after harvest, so color and sugar development must be complete while still on the tree. Look for fruit that has reached full color and gives slightly with a squeeze.
Harvesting lemons: Since they can be used at different stages of ripening, lemon harvesting follows different rules. Green lemons work well for certain culinary applications, while fully yellow fruit offers different flavor profiles. Sonoma’s mild climate means our lemon trees continue producing year-round!
Most citrus stores reasonably well at room temperature for 1-2 weeks, and refrigeration can extend their useability for quite a while.
- Check several fruits for color, firmness, and ease of removal before beginning a full harvest.
- Use clippers or pruners rather than pulling, as citrus stems are strong and too much force may damage both fruit and tree.
- Leave a short stem attached when using clippers to prevent creating openings for decay.
- Harvest based on need rather than all at once.
Harvesting Avocados and Mulberries
Harvesting mulberries: Ripe mulberries are deeply colored (black, red, or white, depending on variety) and will come away from the stem with no resistance.
Harvesting avocados: How to tell when an avocado is ripe presents a bit of a conundrum, because avocados don’t ripen on the tree. They can hang mature for weeks or months, only ripening after harvest.
- Pick one or two test avocados and allow them to soften at room temperature—if they ripen properly within a week, the rest are ready.
- Clip avocado stems rather than pulling to prevent bruising.
- Check mulberries daily during their short season as ripe fruit drops quickly.
Harvesting Tomatoes and Eggplant
Harvesting tomatoes: Start gathering your tomatoes when they’ve developed full color and give a bit when carefully squeezed.
Harvesting eggplant: When eggplants have achieved full color with a glossy skin and feel firm but not hard, they can be removed.
- The best time of day to pick tomatoes is early morning after dew has dried but before afternoon heat. Fruit harvested during coolest temperatures maintains better texture, stores longer, and handles better.
- When to pick cherry tomatoes depends on when you plan to eat them. If you’re going to make a salad in a few days, slightly underripe fruit works better for longer storage. If they’re ripe and perfect, cut some up, sprinkle some salt and pepper, and enjoy!
- Overripe eggplant becomes seedy and bitter, so be sure to keep an eye on their progression.
Harvesting Pears and Apples
The first thing to understand about harvesting apples and pears is that they behave differently once plucked from the tree. Most apple varieties can be eaten immediately after picking, but the same can’t be said about pears.
Harvesting apples: Most varieties are ready when they start to change color from green toward yellow, the seeds darken from white to brown, and the fruit separates easily from the spur when lifted and gently twisted. The “lift and twist” test is crucial—if pulling hard is the only way the apple is coming off, it’s not time to leave the tree!
Harvesting pears: Figuring out when to pick pears requires a little more work. Those that ripen on the tree often develop poor texture with gritty cores, so picking them beforehand is crucial. European pears popular in the North Bay, like Bartlett and Comice, should be harvested when they’ve reached full size, are firm, and come away easily from the branch. After that, they’ll need 2-4 weeks at room temperature before they’re ready to eat.
- Test multiple fruits across different areas of the tree, as ripeness varies based on sun exposure and position.
- Look for color change in the background skin color rather than focusing solely on red blush, which can be misleading.
- Check seed color by cutting a sample fruit—brown or black seeds indicate maturity.
- Use the lift-and-twist method, supporting the fruit in your palm while lifting and gently rotating to separate it from the spur.
- Never pull or yank as this damages fruiting spurs and reduces future production.
Harvesting Figs, Pomegranates, Olives, and Persimmons
Our wonderful climate makes the North Bay hospitable to many Mediterranean varieties. These specialty fruits each have singular harvest requirements that differ substantially from common temperate fruits grown in our region.
Harvesting figs: You’ll need to catch figs at the precise moment of full ripeness. They don’t continue ripening once picked and quickly spoil once mature. Keep an eye out for figs that droop slightly on the stem and feel soft when gently squeezed. A ready-to-pick fig may also show small cracks near the base. When you test it, the stem should separate easily from the branch with minimal force.
Harvesting pomegranates: Don’t be fooled by color. Instead, determine when to pick a pomegranate by its weight, shape, and sound. When a pomegranate is heavy for its size, is slightly square, and makes a metallic sound when tapped, it’s time for collection.
Harvesting persimmons: Variety is key here. Fuyu types are similar to apples and can be harvested and eaten while firm. Meanwhile, Hachiya persimmons must become completely soft before they’re edible. The great thing about Hachiya is that they can be harvested earlier and will continue ripening off the tree.
Harvesting olives: The first thing to know about olives is that these fruits are not something you can pluck off a tree and pop in your mouth. They are not dangerous, but if you take a nibble, you’ll find they are extremely bitter and swallowing them is out of the question. For olives to be edible, they must first be cured in some way. Thus, when to pick olives is directly related to their consumption. Green olives destined for the table must be cured and are picked in September through October. If you plan to make oil, the olives should hang until November or December.
Mediterranean varieties can be a little finicky about timing and so require more frequent monitoring than other orchard fruits.
- Watch for variety-specific indicators as they don’t follow standard ripeness rules.
- Harvest figs immediately when ripe as they spoil within days and quickly attract garden pests.
- Protect pomegranates from rain once they approach maturity to prevent splitting.
- Allow Hachiya persimmons to fully soften before eating to avoid intense astringency.
- Time your olive harvest based on intended use rather than calendar dates.

When to pick pears?
To harvest pears at the right time, you’ll need to know your variety. For example, European pears, like Bartlett and Comice, should be gathered when they’ve reached full size and come away easily from the branch, but are still firm. They’ll then need 2-4 weeks of conditioning at room temperature before they’re ready to eat.
