The risks of waiting too long to harvest garden vegetables

We sowed. We planted. We watered, watched and waited.

And now, beanstalks are reaching for the heavens, and zucchini are seemingly doubling in size overnight.

Timing their harvests is a balancing act, and in many cases you, as gardener, are forced to choose between optimal flavor and yield. Sometimes, one must be compromised in favor of the other 鈥 or to save your crop. Just don鈥檛 wait too long.

Should you wait for tomatoes to fully ripen?

Tomatoes are ripe when their mature color 鈥 red, yellow, orange, purple, etc. 鈥 is uniform. But waiting for that perfect vine-ripened moment often means risking loss. Plump, juicy tomatoes may split open on the vine or be devoured by , who know a perfectly ripe tomato when they see one.

I pick my tomatoes a few days before they reach their peak, then let them continue to ripen upside-down on the kitchen counter (the placement helps prevent bruising at the bottom). In fact, as long as at least half the tomato is taking on color, it will ripen well indoors.

How to know when six other garden vegetables are ready to pick

green, firm and glossy. Standard types are best harvested when they鈥檙e between 6 and 8 inches long (15 to 20 centimeters); pickling types typically top out at 2-4 inches long (5 to 10 centimeters). They grow rapidly, so check plants daily. Wait too long and they鈥檒l turn yellow and bitter.

Green bean pods should be plump but not bulging, and firm enough to snap when bent. Harvest the 鈥渞eady鈥 ones daily because the more you pick, the more the plant will produce; if you don鈥檛 remove the ripe beans, production will slow to a crawl.

, so check plants daily and harvest when the zucchinis are 6-8 inches long and their skin is soft enough to pierce easily with your fingernail. This is also the ideal size for sweetness. Posting a photo of an 18-inch zucchini might amuse your friends, but you probably won’t enjoy eating its tough, seed-filled flesh.

On the other hand, eggplants tend to stop growing when they reach peak ripeness. Shiny skin is another indicator of maturity. Grab it while you can, because if you wait too long, their skin will turn dull and fade in color 鈥 and you鈥檒l be left deciding whether to eat or toss the soft, spongy, bitter, hard-seed-filled poor excuse for an eggplant.

Corn will tell you it鈥檚 ready when its silks turn brown. Husks should be fresh, green and feel full. If you鈥檙e not certain it鈥檚 ready, peel the husk back slightly, just enough to reveal the top row of kernels, and pierce one with your fingernail. If the 鈥渏uice鈥 inside is milky, it鈥檚 ready. If it鈥檚 watery, close it up and try again in a few days. But if there isn鈥檛 any liquid inside, the corn is past its prime. That means the kernels’ wonderful sugars will have turned into starch.

You can鈥檛 go wrong with peppers though: Pick them at their immature green stage or wait until they turn red, yellow or orange. The longer they鈥檙e left on the plant, the sweeter (or hotter) they鈥檒l be, but they鈥檒l be perfectly edible either way.

Harvesting vegetables is morning work

Regardless of the crop, harvest in the morning, just after the dew has dried, for peak moisture content, sugar concentration and texture.

Twist fruit off thin vines or stems, such as those of tomatoes and beans, while holding the main branch with your other hand to prevent damage. Use clean, sharp scissors or pruners when removing fruit from thicker-stemmed plants, such as eggplants.
