Carrots are a popular root vegetable known for their vibrant color and sweet flavor. They grow well in loose, well-drained soil and can be harvested when the roots reach a desirable size, typically 1-2 inches in diameter. Carrots are relatively frost-tolerant, but it is best to harvest them before the first heavy frost to prevent damage.

Potatoes should be harvested before the first frost, especially if they are grown in areas with a short growing season. Frost can damage the potato skins, making them susceptible to rot during storage. Typically, potatoes are ready to harvest when the plants have flowered and the leaves begin to yellow and die back. Be sure to check under the soil for fully developed tubers, which should be firm and free of blemishes.

After digging up the potatoes, allow them to air dry for a few hours before storing them in a cool, dark place. Proper storage is key to ensuring the potatoes remain in good condition for a long period. Potatoes can last several months if stored correctly, with temperatures around 45 to 50 degrees Fahrenheit being ideal.
