Popular crops’ telltale signs of deliciousness

, for instance, doesn’t change color. Although it might be tempting to grow a 15-inch-long squash, it will likely be tough. For optimal tenderness, pick individual fruits when they’re 6-8 inches (15-20 centimeters) long.

All varieties of green beans should be harvested when they are about as thick as a pencil. Once the plant begins producing, check it every day or two and remove beans that are ready; the more you pick, the more the plant will make.

Green peppers at any size but are considered fully mature when they turn red. As a bonus, red peppers are sweeter and contain more nutrients.

There isn’t such a thing as an unripe cucumber — even small ones are crispy and juicy. The hazard here is allowing them to remain on the vine too long, which can result in an off-putting taste and texture. Cucumbers are considered mature when their bumpy skin smooths out.

You’ll know is ready as soon as the silk at the top of its ear turns brown. If you still aren’t sure, peel back a small portion of husk and press your nail into a kernel; if it releases a milky fluid, it’s ripe.

Cantaloupe will practically harvest itself when the time is right: A light tug will release the melon from its stem. If any force is required, it’s not ready.

Honeydew melons are ripe when their bottoms begin to soften, and watermelons when their undersides turn a creamy white color.

When to unearth root crops

Determining when to dig up root crops can pose a bit more of a challenge, as they can’t be visually assessed without disturbing them. But there are some signs to watch for.

You’ll know garlic bulbs are mature when all but five leaves at the top of the plant have turned completely yellow or brown.

Onions are ready when their tops flop over and turn brown.

To assess beets, select one plant and push aside the soil at its base to expose the entire top of the root. Harvest when it measures between 1 1/2 and 3 inches (3.8 and 5 centimeters) wide, depending on variety. If it’s too small, cover it back up, water and try again in a week. Avoid allowing beets to get too big, however, or they’ll lose sweetness and turn tough.

are fully mature when their foliage dies back. But if it’s the so-called “new� potatoes you’re after, dig up the thin-skinned babies 2-3 weeks after the plant blooms. Early-maturing potato types will be ready sooner than the standard, so check tags for variety-specific details. (Note: Due to their delicate skin, new potatoes should be consumed immediately, as they do not store well.)

Carrots are ready when they poke up from underground but can be left in the soil, even into winter, until you need them.
