Harvest and Store Pumpkins and Winter Squash
Pumpkins and winter squash are classic autumn crops that bring both seasonal charm and incredible flavor to the table. Knowing the right time to harvest is key to maximizing their storage life and quality. A mature pumpkin or squash will have a tough, firm rind that resists punctures, while the vine and surrounding foliage will begin to dry out and die back. When harvesting, use clean pruning shears to cut the fruit from the vine, leaving a few inches of stem attached to help reduce the risk of rot. For best results, harvest on a dry day and gently clean away any soil before allowing the fruit to dry completely.
Proper storage helps preserve pumpkins and winter squash for months after harvest. Place them in a cool, dry, and well-ventilated location where temperatures stay between 50°F and 55°F (10°C to 13°C). Arrange each pumpkin or squash in a single layer with space between them to encourage airflow and prevent moisture buildup. Check stored produce regularly and remove any fruit showing signs of soft spots, mold, or decay. When stored under ideal conditions, pumpkins and winter squash can remain fresh for up to 3 to 4 months, providing delicious ingredients for soups, roasted dishes, baked goods, and other comforting winter recipes.
Harvesting Carrots
Carrots are a nutrient-rich root vegetable that can be used in everything from fresh salads to roasted side dishes, soups, and hearty stews. When harvesting carrots, carefully loosen the soil around the roots and pull them up by the greens. A garden fork can also help lift them from the ground while minimizing the risk of root damage. For the best flavor and texture, harvest carrots once they reach their full size but before they become overly mature. Leaving them in the soil too long can result in tougher, woody roots with a less desirable taste.
To keep carrots fresh after harvest, store them in a cool, humid environment. Begin by trimming off the leafy tops, as they can draw moisture away from the roots and shorten storage life. Gently brush or rinse away excess soil, but avoid excessive washing, which can increase the risk of spoilage. Place the carrots in a perforated plastic bag or pack them in damp sand or sawdust to help retain moisture. Store them in the refrigerator’s crisper drawer at temperatures between 32°F and 40°F (0°C and 4°C). With proper harvesting and storage techniques, carrots can remain crisp, flavorful, and ready to use for several months throughout the winter season.
Harvest and Store Swiss Chard
Swiss chard is a nutrient-rich leafy green that adds vibrant color and fresh flavor to homegrown meals. Because it thrives in cool weather, it is an excellent crop for late-summer and fall harvesting. As the growing season comes to an end and frost approaches, it is time to harvest any Swiss chard still growing in the garden. Throughout the season, harvest Swiss chard by cutting the outer leaves at the base while leaving the inner leaves intact. This cut-and-come-again method encourages continuous growth and allows the plant to produce fresh leaves for months. For the best flavor and texture, harvest leaves when they are young and tender, typically when they reach 6 to 8 inches long. When frost is in the forecast, harvest all remaining Swiss chard plants. Cut the plant about 1 inch above the top of the stalk. If you have been harvesting only the outer leaves during the growing season, the plant will likely have developed a stalk several inches long. Leave this stalk in place and avoid cutting into it. If this is the first harvest of the season, cut the stalks approximately 1 inch above the soil surface. At harvest time, you will usually have a mix of both large and small leaves.
To store Swiss chard, begin by removing any damaged, yellowing, or wilted leaves. Rinse the healthy leaves thoroughly under cold running water to wash away dirt and debris. Dry them gently with a clean kitchen towel or paper towel before refrigerating. For longer-lasting freshness, follow the storage methods outlined in my post on How to Keep Your Lettuce from Spoiling. Check stored leaves regularly and remove any that show signs of deterioration to help prevent spoilage from spreading to the rest of the harvest. If you harvest more Swiss chard than you can use within a few weeks, consider preserving the excess by blanching and freezing it. Visit my post on How to Blanch and Freeze Swiss Chard for step-by-step instructions. When properly vacuum-sealed after freezing, Swiss chard can maintain excellent quality in the freezer for several years.
How to Harvest and Store Brussel Sprouts
Brussels sprouts are one of my favorite fall garden vegetables. Growing up, we called them “mini cabbages,” and I always looked forward to the day they were ready to harvest. When harvesting Brussels sprouts, begin at the bottom of the stalk and work your way upward, gently twisting or cutting off the firm, compact sprouts. For the best flavor and texture, harvest sprouts when they are about 1 to 2 inches in diameter and the leaves are tightly wrapped. If the outer leaves start turning yellow or loosening, the sprouts may be past their peak quality. Picking from the bottom first allows the upper sprouts to continue maturing, providing a longer harvest period throughout the season.
To store Brussels sprouts properly, keep them in a cool, humid environment. Remove any damaged or loose leaves, then rinse the sprouts under cold water to wash away dirt and debris. Dry them thoroughly with a clean kitchen towel or paper towel before storing. For maximum freshness, place the sprouts in a Green Vegetable storage bag or an airtight container in the refrigerator’s crisper drawer. If using an airtight container, layer the sprouts between sheets of paper towel to absorb excess moisture and help prevent spoilage. Cheesecloth can also be used as an alternative to paper towels. The ideal storage temperature is between 32°F and 40°F (0°C to 4°C). When stored correctly, Brussels sprouts can remain fresh for up to a month, making it easy to enjoy their delicious flavor and versatility in a variety of recipes.
Harvest and Store Potatoes
Potatoes are one of the most rewarding crops to grow at home, offering a dependable harvest and incredible versatility in the kitchen. Farmer Fred wasn’t always a fan of potatoes until we started growing colorful purple and red fingerling varieties. Their naturally creamy texture, rich flavor, and vibrant appearance quickly made them a favorite. Beyond their great taste, these potatoes contain antioxidants and essential nutrients that support brain health and cognitive function, making them a valuable addition to a balanced diet.
For the best harvest, wait until the potato plants have fully matured and the foliage has turned yellow and died back. Using a garden fork or shovel, carefully loosen the soil around each plant, starting from the outer edges and working inward to avoid damaging the tubers. Once harvested, allow the potatoes to cure in a sunny, dry location for a few hours. This helps toughen the skins, reducing the risk of damage during storage and extending their shelf life.
To keep potatoes fresh for months, store them in a cool, dark, and dry environment with good airflow. Avoid refrigeration, as cold temperatures can convert starches into sugars, affecting both flavor and cooking quality. A basement, root cellar, or other well-ventilated space maintained between 45°F and 50°F (7°C to 10°C) is ideal. Place potatoes in a burlap sack, paper bag, or loosely covered container to prevent light exposure while allowing air circulation. Check stored potatoes regularly and remove any that are sprouting or showing signs of spoilage. With proper storage conditions, your homegrown potatoes can remain fresh and ready to use in a wide variety of recipes throughout the season.
Storing Onions For the Winter
Onions are one of the most popular garden vegetables and a staple ingredient in many recipes featured on Grow With Dr. Joanette. To harvest onions at the right time, wait until the green tops naturally yellow, wilt, and fall over. Carefully loosen the soil with a garden fork or shovel and lift the bulbs from the ground, taking care not to nick or bruise them. Place the harvested onions in a warm, dry location with plenty of airflow for approximately two weeks. This curing process allows the outer skins to dry and helps extend the onions’ storage life.
For long-term storage, keep cured onions in a cool, dark, and dry environment. Once the bulbs are fully cured, gently brush away excess soil without washing them, as added moisture can lead to spoilage. Trim the tops, leaving about one inch of the stem attached to help reduce sprouting. Store onions in mesh bags, hanging baskets, or other breathable containers that promote air circulation. Ideal storage temperatures range from 32°F to 40°F (0°C to 4°C). Avoid storing onions alongside potatoes because both crops release moisture and gases that can accelerate deterioration. Check stored onions regularly and remove any soft, sprouting, or damaged bulbs. When properly harvested, cured, and stored, onions can remain fresh for several months, ensuring a steady supply of flavorful bulbs for cooking throughout the year.
How to Harvest and Store Garlic
Garlic is widely recognized as a culinary superfood, valued for its strong aromatic flavor and its wide range of health-supporting properties. It is rich in antioxidants and natural anti-inflammatory compounds that help protect brain cells from oxidative stress and may support reduced risk of neurodegenerative conditions such as Alzheimer’s disease and dementia.
For harvesting garlic, wait until the plant leaves begin to turn yellow and naturally dry down. Carefully loosen the soil around the base using a garden fork or shovel, taking care not to cut or bruise the bulbs. Lift the garlic gently from the ground, remove excess soil, and place the bulbs in a warm, dry, and well-ventilated space to cure for about two weeks. This curing stage is essential for intensifying flavor and significantly improving long-term storage quality.
Proper garlic storage requires a cool, dark, and dry environment to maintain freshness and prevent spoilage. If you plan to create decorative garlic braids or bundles, choose softneck varieties, as they are more flexible and better suited for weaving. Hardneck garlic is not ideal for braiding because its stiff stems can break, and as they dry, the bulbs may detach from the braid.
If braiding is not your method, allow the garlic to fully cure in a well-ventilated, shaded area. Once cured, trim the roots and gently clean off any loose outer layers while keeping the protective papery skin intact. Do not peel the cloves until you are ready to use them, as this helps preserve freshness. Store bulbs in mesh bags, breathable baskets, or ventilated containers placed in a cool environment maintained around 60–65°F (15–18°C). Avoid refrigeration, as excess moisture and cold temperatures can trigger sprouting or mold growth. With proper handling and storage, garlic can last for several months while retaining its flavor, aroma, and culinary value.
Harvesting, Drying, and Storing Fresh Herbs
Herbs are a flavorful and aromatic upgrade to almost any dish, bringing freshness, depth, and natural fragrance. They are especially valuable for low-salt or no-salt diets because they enhance taste without relying on sodium. Growing your own kitchen herb garden is a simple way to always have fresh herbs within reach. During colder months, potted herbs can be moved to a sunny windowsill or grown indoors using an AeroGarden. An AeroGarden can also be a fun and educational indoor gardening project for grade-school-aged children, helping them learn how plants grow year-round.
If you plan to harvest herbs from your garden for drying and long-term use, timing is important—pick them when they are at peak flavor for the best results. Most herbs can be harvested continuously throughout the growing season, but avoid removing more than one-third of the plant at a time to ensure healthy regrowth. For leafy herbs like basil and parsley, trim the outer leaves or stems first, working from the top down. For woody herbs such as rosemary and thyme, cut stems just above a leaf node to encourage fuller, bushier growth.
Herbs can be stored in several ways depending on the type and how long you want to preserve them. Freshly cut herbs can be placed in a jar of water like a bouquet, then loosely covered with a plastic bag and refrigerated to maintain freshness. For long-term storage, drying is a popular method—simply bundle herbs together and hang them upside down in a dry, dark, well-ventilated space. Once fully dried, crumble the leaves and store them in airtight containers away from sunlight. Alternatively, a food dehydrator can be used on the lowest heat setting, typically drying herbs within 1–2 days.
Freezing Herbs
You can preserve basil in the freezer by rinsing the leaves, drying them thoroughly, and placing only the leaves (without the stems) in a freezer-safe bag. Once frozen, the leaves can be crumbled and used just like freshly chopped basil in sauces, soups, and your favorite recipes. Another easy method is to finely chop basil and other herbs, then place them into ice cube trays filled with water or olive oil. After freezing, transfer the herb cubes to a freezer-safe container or storage bag for convenient use.
When herbs are harvested and stored correctly, they can maintain their flavor and aroma for several months. This allows you to enjoy the fresh taste of garden herbs year-round, even when fresh herbs are out of season or not readily available.
As summer comes to an end, the late-season harvest delivers a generous supply of vegetables and herbs that can nourish your family throughout the colder months. By using proper harvesting, curing, and storage methods, you can preserve the freshness, flavor, and nutritional value of pumpkins, winter squash, carrots, Swiss chard, Brussels sprouts, potatoes, garlic, onions, and herbs for long-term enjoyment. Whether you’re preparing roasted squash for comforting soups, serving crispy Brussels sprouts at holiday gatherings, or enhancing recipes with homegrown herbs and garlic, your harvest can continue to provide delicious meal options long after the growing season ends.
