Anticipation is likely one of the reasons it seems to take forever for your tomatoes to turn red. Dozens of varieties exist and tomatoes are fairly easy to grow, but it's the fresh, juicy taste and texture that make tomatoes the most popular crop grown in home gardens across the United States.1 Waiting for them to ripen to perfect red can seem endless, but besides anticipation there are several non emotion-based reasons for why your tomatoes are still green. Here are some of the most common reasons why your tomatoes aren't turning red, plus what you can do to speed up the ripening process. Temperature Too Hot or Too Cold Temperature is one of the bigger factors for ripening tomatoes and a few degrees too hot or too cold puts the process on hold or even stops ripening altogether. The ideal temperature tomatoes need to acquire their red color is 68 to 77 degrees F.2 At 85 degrees, the production of lycopene ceases leaving large green fruits on the vine until temperatures lower to more better levels. Temperatures consistently below 60 degrees F. also inhibit ripening. Fruits that are fully mature and have a slight blush can be harvested and brought indoors to finish ripening. They do not need to sit in a sunny window as long as the correct temperature is provided. Too Much Direct Sunlight Even though it might seem counterintuitive, too much sun exposure can slow down ripening. The heat is more important than light for ripening, and too much bright, hot, direct sunlight can raise temperatures to levels that inhibit lycopene production. Pruning leaves away from mature tomatoes to give them more sun exposure can also cause sunscald and cracking. Too Much Water Tomato plants need 1 to 2 inches of water per week when vines are actively growing and producing fruit. But once fruits reach their mature size, ripening occurs more quickly if irrigation is reduced or even stopped completely. Less water stresses the tomato plant and sends it into survival mode. The plant will focus energy into producing viable seed, which helps accelerate ripening. Insufficient Nutrients Tomatoes require a lot of nutrients and micronutrients throughout the growing season. Phosphorous and potassium are particularly important for the production and synthesis of lycopene in the fruits. Insufficient amounts can cause slow or uneven ripening. When the first small fruits appear on the plant, feed with a fertilizer higher in phosphorous such as and NPK 5-10-5. Too Much Nitrogen Tomato plants benefit from an application of balanced fertilizer such as an NPK 10-10-10 early in the season. This supports vine and foliage growth and encourages good root development and flower production. Once mature fruits are on the vine, fertilizing with a product that contains too much nitrogen can take away from ripening by refocusing energy on foliage growth. Once green fruits have reached a fully mature size, withhold fertilizer and allow the natural processes of ripening to take place in the fruit. Lack of Pruning Limiting the number of vines on a plant by removing early suckers is another way to focus energy into the production and ripening of fruit. Not every vine produces fruit and plants with unproductive vines or vines overloaded with fruit will struggle. This is especially true for determinate type tomato plants that produce many fruits all at the same time. Early pruning of your tomato plants results in higher quality fruit that ripens more easily and quickly. It's Not Supposed to Be Red It's important to understand, starting out, what your tomato type will look like when fully ripe. Many varieties ripen to different shades of red or may be orange, pink, purple and even striped. If you're waiting for your tomato to turn red, make sure that's the color it's supposed to be when it's ready to pick. Check your seed package for how many days to harvest for the tomato variety you've chosen. Some varieties need more or less growing time and may not work as well in your climate.

Pick a space for your herb garden that can provide the proper light, soil nutrients, and humidity your herbs need. Pick and place herbs according to their needs—some plants need less water than others. After harvesting herbs they can either be frozen or dried in order to keep them viable for longer. Herb gardens are the perfect introduction to gardening and supply your senses and pantry with fresh flavors and scents. Whether you plan to grow herbs in containers or a small plot, here are the things you need to know to start a successful herb garden. Pick a Space for Your Herb Garden Herb gardens are so popular because they are easy to start and maintain; they grow quickly and you can begin harvesting within a few weeks. The size of your herb garden is up to you and depends on the quantity and variety of herbs you want to grow. Light Almost all herbs require at least 6 hours of full sun daily. A few such as chervil, mint, chives, and cilantro can be grown in an area with light shade. Soil Herbs need well-draining soil. They will no thrive in heavy, wet soil. Adding compost to clay soil will help improve the structure and drainage. The soil does not have to be highly fertile; too many nutrients tends to produce excessive amounts of poorly-flavored foliage. Temperature and Humidity Mediterranean herbs like basil, thyme, rosemary, oregano, and lavender like warm, sunny, dry conditions. Most perennial and biennial herbs can overwinter if they are protected with layers of mulch. Established herbs can tolerate dry conditions but supplemental water is recommended during periods of drought. Use mulch to conserve soil moisture, but keep it away from the base of the plants to prevent stem rot. Want more gardening tips?

Pick Which Herbs You Want to Grow Most people plant the herbs they enjoy using for cooking, making teas, or drying for potpourri. Some make selections based on fragrance or bloom color. The beauty of an herb garden is that it is personal to your preferences. It is a good idea to group your chosen herbs by their watering needs to prevent over-watering those that prefer drier conditions. Drought-Tolerant Herbs Borage: Once established, allow the soil to dry out between waterings. Fennel: Drought-tolerant once established; allow the soil to dry between waterings. Lavender: Lavender will not survive wet roots and heavy soil. Marjoram: Drought-tolerant and prefers dry soil with occasional watering. Oregano: Thrives in dry and warm climates with low rainfall levels. Sage: A drought-tolerant plant that prefers soil to dry out between waterings. Rosemary: Prefers slightly drier conditions and minimal watering. Thyme: Water only when the soil is completely dry. Winter savory: Once established, prefers dry soil. Herbs with Moderate Watering Needs Basil: A broadleaf herb, it requires more water than herbs like thyme, rosemary, and sage. Bay laurel: For healthy leaves, keep the soil evenly moist. Catnip: A member of the mint family, catnip requires consistent moisture to flourish. Chervil: Prefers evenly moist soil with good drainage. Chives: Although drought-tolerant, chives must be watered evenly throughout the growing season for high yields. Cilantro: The soil should be kept evenly moist for tender leaves. Dill: Requires consistent moisture levels to flower and produce seeds. Lemon balm: Prefers soil that is moist but never wet. Lemon verbena: Requires regular watering. Mint: Thrives around water and can tolerate wet roots. Parsley: Evenly moist soil produces the most tender leaves of flat or curly parsley. Tarragon: Young plants need regular watering to become established. Propagating Herbs There are many ways to propagate herbs, and doing so can keep your herb garden fresh and perpetually growing for years. By Seed Nearly all herbs grow well from seed that you've saved or purchased. Fine herbs like anise, cilantro, dill, and fennel should be directly sown into the garden once the danger of frost has passed because they do not transplant well. Basil, parsley, sage, and thyme can be started indoors and transplanted into the garden when temperatures warm. After planting seeds in well-tilled soil with good drainage, water lightly until they germinate. From Cuttings To quickly establish new plants, herbs can be propagated from cuttings. Take cuttings in spring or early summer when the plant is actively growing; select a 3 to 4-inch stem that is healthy and tender. Strip the leaves off the bottom two inches and dip the cut end in rooting hormone. Place the stem in a small pot of moistened potting soil. Cover the pot with a plastic bag and place it in an area with bright, indirect light. Keep the soil moist and remove the plastic bag when new leaves begin to grow. Transplant the cutting into the garden once the plant has at least 3 or 4 sets of new leaves. Propagating Without a Plant If you don't have herb plants already established, there are some herbs you can grow from supermarket purchases like mint, basil, thyme, and more. By Division Herbs that have a clumping habit like tarragon, chives, and mint can be divided to create new plants. Use a garden trowel to gently dig up the clump of herbs. Use a clean, sterile knife to separate individual plants and replant or share them with others. Harvesting Herbs harvesting mint Valeriy_G / Getty Images Once an herb plant has enough foliage to maintain growth, fresh leaves can be harvested. It's best to harvest herbs before they flower or go to seed because leaf production declines. Snip stems at a leaf node with sharp, sterile clippers. For the best flavor, pick leaves or seeds after the morning dew has evaporated but before temperatures are high. Before using, discard any bruised or soiled leaves and inspect the herbs for insects or foreign matter. Rinse the herbs under running water and shake gently to remove excess moisture. How to Preserve Herbs The two best methods for preserving herbs are freezing and drying. Depending on the herbs you're drying, one method might suit your needs better than the other. By Freezing Tender herbs like basil, chives, cilantro, dill, lemon balm, mint, parsley, and tarragon freeze well in small batches. After harvesting and rinsing the herbs, pat the herbs dry. Place the herbs in a freezer bag, seal the bag, and place it in the freezer. To freeze in pre-measured portions, chop the herbs finely and place them in an ice cube tray. Add a small amount of water and allow the tray to freeze. When solid, pop out the cubes and store them in plastic bags. By Drying Rosemary, sage, thyme, and winter savory are the easiest herbs to dry and will retain the most flavor and color. After harvesting and rinsing the herbs, pat them dry with a paper towel. Form small bunches and tie them with cotton string. Hang the bunches upside down in a warm, well-ventilated place until the moisture evaporates. Avoid hang in direct sunlight that can strip flavor and color. The herbs are dry when the leaves crumble and the stems break when bent. Store dried herbs whole, crumbled, or ground in a cool, dark spot in a labeled airtight container for up to six months for the best flavor.

Basil is a beloved herb and an essential ingredient in every season. But is it possible to keep this plant as a perennial and enjoy its tasty leaves year after year? If you live in USDA hardiness zones 10 and 11, you could count on sweet basil as a perennial herb. For the rest of the country, it is considered an annual and will not come back the next year. However, with some planning, you can have fresh sweet basil at hand, whether you grow it indoors or ensure it reseeds in your garden. Ahead, learn more about growing basil year-round. Is Basil a Perennial? Sweet basil (Ocimum basiiicum L.), is not a perennial except in USDA hardiness zones 10 and 11. The same facts apply to other types of basil like Thai basil and spicy cinnamon basil. How to Make the Most of Your Basil Harvest If you want to keep fresh basil on hand year-round, follow these tips to make the most of your basil harvest. Grow basil indoors. If you live in a cool climate, keep basil available by growing it indoors in pots year-round. Protect the basil plants. To extend an outdoor growing season, protect the plants from late or early frosts by using row covers or individual plant protectors. A glass jar or plastic milk container will protect the plants at night but should be removed the next morning. Stagger plantings. If growing basil from seed, stagger the sowing dates so the seeds germinate at least two weeks apart. If using nursery seedlings, purchase and plant about two weeks apart to extend the season. Remove basil flowers. If flowers form on the basil stems, pinch them off immediately. The energy of the plant should go into producing more and larger leaves, not flowers that become seeds. Harvest frequently.Regular removal of basil leaves will encourage the plant to branch out and sprout more leaves throughout the season. Freeze extra leaves. To freeze fresh basil leaves, blanch them in boiling water for 30 seconds, pat them dry, and freeze flat on a parchment-lined baking sheet. Store the frozen leaves in airtight containers in the freezer. Dry extra leaves. Use a dehydrator, oven, or microwave to dry basil leaves quickly. Once dry, crumble the leaves and store them in airtight containers. How to Grow Basil Year-Round Unless you live in USDA hardiness zones 10 or 11, you will need to either grow basil indoors or do a combination of outdoor gardening and indoor containers. For outdoor plants, plant seedlings in the ground or containers in the spring once the last chance of frost has passed. You can get a head start on harvesting by starting seeds or seedlings indoors while the weather is still cool. To grow indoors, you can start with seed, seedlings, or stem cuttings. Most indoor basil plants produce for about one year if maintained properly. Indoor basil containers need regular watering and plenty of bright light to thrive. A grow light is a great way to keep basil healthy if you don't have a sunny window. How to Grow Basil as a Perennial Annual basil plants in the garden will often self-sow if you don’t pinch back their flowers. You may be lucky enough to find some new seedlings in the garden in the spring if the weather cooperates. However, not all seeds germinate and the new seedlings will also be annuals. So, you can replant or move to a warmer climate if you'd like to be sure basil continues to come back every year. If you are living in a semi-tropical area, basil seeds can be planted in early spring or fall in moist but well-drained soil. The plants are sensitive to frost and the leaves of many varieties will turn black and drop off the plant when temperatures drop below 40°F. To save seeds from basil, leave the flowers on the plant until they die, allowing the seeds to turn brown and dry. Separate the seed from the seed capsules and store them in a cool place in a well-sealed container to replenish your crop.
