When can you pick fruit from your tree?

Most tree fruits release a sweet scent into the air when their fruits are ready to taste, but even so, it’s tough to gauge the exact moment of peak ripeness. Times will vary year by year, and different varieties will "come in" at different times. Here, by fruit variety, are a few signs that indicate ripeness.

Apples 

You might have heard that ripening apples give off the hormone ethylene gas. One of its effects is to cause the separation of the stem from the tree, causing the apples to fall. It is not the best test for ripeness.

Many apple varieties are ready when you can easily pull them from the tree. Don't yank. Grasp gently and give them a slight twist. Another way to tell is by looking at the seeds. When the seeds turn brown, the fruit has hit its peak taste.

I still maintain that the best test is to bite into an apple. Too starchy and tart means it's under-ripe. Pithy or mealy means it's overripe. An apple is ready when it’s juicy and sweet!

Pears

Pears should be picked when just starting to change color from green to a tinge of yellow. At this point, the fruits still will be hard, but will pull away easily from the tree. Give them a few days to a few weeks to continue ripening once they're off the tree. Allowing pears to fully ripen on the tree produces fruit with a gritty texture and quickly goes to mush.

Stone Fruits

For fresh eating, allow them to ripen fully on the tree. Most will not continue ripening or sweetening post-harvest. You've probably had some flavorless, limpid peaches or cherries from the grocery store picked when immature and, consequently, softened in shipping.

If you plan to can or freeze stone fruits, pick them a little on the firm side. They will soften more with processing. You probably will be adding sugar, which will compensate for any loss of natural sweetness..

Stone fruits are ripe when they look fully colored, and the flesh has started to soften slightly to the touch. The only real test is by taste. Stone fruits don't store well, so enjoy them while you can!

Grapes and Citrus

These fruits stop ripening when they are picked. For juicy, sweet flavor, they need to be completely ripe before harvesting, and ripening can take months. It's hard to tell ripeness by touch; once again, the best test is by taste.

Citrus does not separate from the tree quickly, so rather than pulling, I recommend cutting these fruits from their branches.

General Harvesting Tips

Use caution when eating fruit that has fallen from the tree. Fruits sometimes drop from trees because they are infested, so check before you munch down on a fruit full of worms!

Be gentle. Don't tug and tear the stem off soft fruits like strawberries, cherries, and even tomatoes; you may injure the stem end, which is an invitation for rot.

Don't toss fruits into your basket or container, and don't pile them so high that the top layers crush the fruits under them. To prevent the mess of staining from juice running out of the collection container, line it with a layer of paper towels before filling with harvested fruit.

Don't leave fruits on the tree or lying on the ground. This will cut down on the chance of disease or encouraging pests from overwintering.

For the best flavor, freshly harvested fruits should be stored at room temperature. But if your taster is like mine, you'll trade a little flavor for the exhilaration of biting into an icy cold piece of fruit!

Until next week, I'll be here at Watters Garden Center helping gardeners select and plant their new fruit trees.
