Strawberries are very susceptible to frosts in the spring. Overfertilization will cause excessive vegetative growth, reduce yields increase losses from frost and foliar disease and result in winter injury. This application is made to keep the plants in a vigorous condition and to promote new growth causing the development of more fruit buds. Water the fertilizer in to get it down to the root zone. After the first harvest in the second season strawberries should be fertilized after renovation in July. Fertilizationīefore planting apply one pound per 100 square feet of a 10-10-10 fertilizer and dig into soil at least six to eight inches deep. Strawberries need about one inch of water per week during the growing season. These plants could harbor verticillium wilt, a serious strawberry disease. Do not plant strawberries where peppers, tomatoes, eggplant and potatoes have been grown. They need full sun for the highest yields, at least 6 hours per day. Strawberries prefer a well drained soil, high in organic matter. Strawberries are among the most widely grown fruit in the home garden. Removing the flowers promotes root and runner development thereby insuring a large crop the following year.įor everbearing and day-neutral strawberries, remove the flowers until the end of June and then after that date allow the flowers to remain to set fruit for a summer/fall harvest. Blossom Removalĭuring the first growing season, remove flowers of June-bearing strawberries as soon as they appear. During the first two or three weeks of growth, the planting should be weeded then the bed should be mulched. Plants are set about one foot apart in multiple rows. Multiple rows are arranged in groups of two, three or four plants with a two foot walkway between each group of rows. Removing the runners causes the mother plant to develop more crowns and flower stalks. In this system all the runners are removed so only the original mother plant remains. This is the best system for growing day-neutral and everbearing strawberries. Even though more care is needed under this system, advantages include higher yields, larger berries and fewer disease problems. All other runners are pulled or cut from the mother plants. The daughter plants are spaced to root no closer than four inches apart. The mother plants are set eighteen to thirty inches apart in rows three to four feet apart. This system limits the number of daughter plants that grow from a mother plant. Daughter plants are allowed to root freely to become a matted row no wider than two feet. In this system, the strawberry plants should be set eighteen to thirty inches apart in rows three to four feet apart. This system is the best for growing June-bearing cultivars. The plant on the left is set too shallow the plant on the right too deep. The center plant is set correctly, with the soil just covering the tops of the roots. After four or five weeks, the plants will produce runners and new daughter plants. Set the strawberry plant in the soil so that the soil is just covering the tops of the roots. ![]() Try to plant strawberries on a cloudy day or during the late afternoon. This is usually in March or April allowing the plants to become well established before the hot weather arrives. Plant strawberries as soon as the ground can be worked in the spring. *N = adapted to region north of Interstate 80 C = adapted to region between Interstate 80 and Interstate 70 S = adapted to region south of Interstate 70. R = resistant to this disease S=susceptible to this disease. Strawberry cultivars for Illinois, listed by season from earliest to latest within groups and d isease resistance Strawberry varieties should be selected on the basis of dessert quality preserving quality disease resistance and season of maturation. They can also be used as an edging plant or a groundcover. They can be grown in terraced beds, barrels or pyramids. These strawberries produce just a few runners.Įverbearing and day neutral strawberries are great for gardeners who have limited space. ![]() Everbearers do not produce many runners.ĭay neutral strawberries will produce fruit throughout the growing season. They are classified into early, mid-season and late varieties.Įverbearing strawberries produce three periods of flowers and fruit during the spring, summer and fall. June-bearers produce flowers, fruits and runners. June bearing strawberries produce a crop during a two-to-three week period in the spring. Fruits of day neutral plants and everbearers are usually smaller than June-bearers fruit. ![]() June bearing or spring bearing, everbearing and day neutral are the three types of strawberries grown in Illinois.
