once it has gone to seed, its lifespan is essentially over, and other than potential harvesting of the seed the plant can be removed.Like many other leafy vegetables, it’s advisable to regularly harvest leaves from the plant to encourage faster and bushier growth.Unlike many other green plants, spinach does not grow from cuttings, as the leaves and stems will not form new roots.Spinach seed can be stored for a few years in normal seed storage options, but the tiny seeds lose their ability to germinate when they get too old.It’s possible to transplant spinach… I just don’t recommend it if it was initially grown in a container!It’s better to just plant your spinach directly in the soil as seed and allow it to develop normally.Harvesting and Storing Spinach.Once you’ve got a bunch of spinach plants, it’s definitely time to start harvesting your produce!Many people prefer to wait until their plant has developed some good leaf growth, but spinach can also be grown as a sprout or as microgreens.To harvest baby spinach leaves, wait until it’s formed a rosette of at least five to six leaves, and then harvest.If you remove all of the leaves, the plant will not grow to maturity, so if you plan to harvest baby spinach, regularly re-sow to maintain steady production.Be sure to leave at least a portion of the leaf stem on the leaf as removal of the stem will cause the leaf to wilt more quickly.To clean it, fill a large bowl with cool water and place your spinach inside.Once they’re clean, remove any damaged, wilted, diseased or discolored leaves, and then dry the spinach leaves completely.Be sure to remove any excess air in the bag before freezing!Spinach is a low-acid food, so must be canned with a pressure canner to avoid the risk of botulism.To dry your spinach, follow the manufacturer’s directions on your dehydrator or freeze dryer.As long as you’ve followed the steps mentioned above, you should be able to grow a good crop of spinach.Growing Problems.Plants that bolt to produce seed are suffering from weather that’s just simply too warm.That doesn’t make for a good spinach harvest!There are also some great DIY pest control methods that work against slugs and snails!It’s best to avoid downy mildew by ensuring good airflow around your plants and by watering the soil rather than the leaves.Powdery mildew can also become a problem on spinach, but it can be treated with repeated applications of neem oil.Growing resistant varieties and preventing aphids on your spinach are both essential protections. .

Spinach Planting & Spinach Growing

This plant food works in tandem with great soil to help you achieve the best possible spinach harvest.In the spring, plants will grow tall and bloom (called bolting) as soon as the days are longer than 14 hours.Our variety is slow to bolt, which is a real bonus for gardeners who don’t have the luxury of long stretches of mild weather. .

The Ultimate Spinach Growing Guide

Spinach is one of the most satisfying cool-weather crops to grow, producing large yields of vitamin-rich, dark green leaves that are excellent for salads and for cooking.Since both hot weather and long days trigger spinach to bolt (send up a seed stalk) quickly, the secret to success with this crop is to start sowing seeds as soon as possible in spring; to make small, frequent plantings during late spring and summer; and to concentrate on fall as the season for the main crop.Prepare the soil the previous autumn, and you'll be able to drop the seeds in barely thawed ground come spring.In warm climates, plant spinach in the shade of tall crops such as corn or beans.Using cold frames or heavyweight row covers, you can grow spinach all winter in many parts of the country.Downy mildew, which appears as yellow spots on leaf surfaces and mold on the undersides, occurs during very wet weather.Harvest the entire crop at the first sign of bolting by using a sharp knife to cut through the main stem just below the soil surface.This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses. .

Ipomoea aquatica

Species of plant.Ipomoea aquatica is a semi-aquatic, tropical plant grown as a vegetable for its tender shoots.This plant is known in English as water spinach, river spinach, water morning glory, water convolvulus, or by the more ambiguous names Chinese spinach, Chinese watercress, Chinese convolvulus or swamp cabbage, or kangkong/kangkung in Southeast Asia and ong choy in Cantonese.Ipomoea aquatica grows in water or on moist soil.Propagation is either by planting cuttings of the stem shoots, which will root along nodes, or by planting the seeds from flowers that produce seed pods.Origin [ edit ].The origin of I. aquatica is not quite clear, but it is agreed that it is native to Southeast Asia.Cultivation [ edit ].Ipomoea aquatica is most commonly grown in east, south, and southeast Asia.Requirements for climate and soil [ edit ].High soil moisture is beneficial for the growth.Traditional cultivation methods [ edit ].Water spinach is cultivated in a variety of systems.Water spinach cultivated with the dryland method is ready for harvest 50 to 60 days after sowing.This helps to retain water for the water spinach.The seedlings to be used in this methods are usually grown in a nursery on a dry field, as the germination under water is quite poor.One cutting is an approximately 30 centimetres (12 in) long cut from the stem containing seven or eight nodes.Also, the harvesting differs from the dryland system: In the wetland, the upper part of the main shoot is cut at about water level.Use of fertilizer [ edit ].One study has determined, that the highest yields are produced with the application of 60 kg/ha of N, 90 kg/ha of P 2 O 5 and 50 kg/ha of K 2 O for the first harvest.Ipomoea aquatica is listed by the USDA as a noxious weed,[30] especially in the states of Florida, California, and Hawaii, where it can be observed growing in the wild.[31] In the US, water spinach has mainly become a problem in Florida; why is unclear although the fast growth rate has been cited as a threat to native plants in certain areas of Florida.[37] In Singapore, Indonesia, and Malaysia, the tender shoots along with the leaves are usually stir-fried with chili pepper, garlic, ginger, dried shrimp paste (belacan/terasi) and other spices.In Indonesian cuisine it is called kangkung, boiled or blanched together with other vegetables it forms the ingredient of gado-gado or pecel salads in peanut sauce.In the Philippines, where it is called kangkóng, the tender shoots are cut into segments and cooked, together with the leaves, in fish and meat stews, such as sinigang.In adobong kangkóng (also called apan-apan), it is sautéed in cooking oil, onions, garlic, vinegar, and soy sauce.Animal feed [ edit ].Health effects [ edit ].Medicinal use [ edit ].Water extracts of I. aquatica showed a blood sugar-lowering effect in Wistar rats.Many of the waters where water spinach grows are fed by domestic or other waste.Mercury in water spinach is composed mostly as methylmercury and has the highest potential of becoming a threat to human health.Ipomoea aquatica.Asian-styled stir fry ipomoea aquatica served in chili and sambal.Ipomoea aquatica. .

Water Spinach

Plant stems are not strong, but plants grown in beds support each other and produce longer stems with less branching, which is what the market prefers.Harvest of the entire plant can be made 50 to 60 days after planting.Shoots regrow readily and in Massachusetts, growers will get two to three cuttings of water spinach before frost.Holes in the leaves also reduce the marketability of the greens.Insecticides used should include only materials that have a broad label for all leafy green crops, such as neem.High numbers of aphids cause leaves to curl.The specific target pest does not have to be listed on the label but the leafy greens crop group must be on the label.Water spinach requires rapid and careful post-harvest handling to maintain quality. .

Water Spinach

Flowers: showy, white, or pale pink to lilac; broadly funnel shaped, "morning-glory" like; solitary or in few-flowered clusters at leaf axils. .
