  1. Growing Strawberries K-State Research & Extension Ward Upham

  2. Strawberries: Background PAggregate fruit PCan expect 1 to 12 pounds of fruit per plant.

  3. Strawberries:Background How Fruit is Borne

  4. Strawberry: First Steps P Find source of virus-free plants: normally planting lasts 3 to 4 years P Strawberries should not be planted after tomatoes, peppers, eggplants, or potatoes because they can be a source of Verticillium wilt P Choose cultivar(s)

  5. Types of Strawberries P June Bearers: Produce crop in May. Produces more total fruit than other types. P Everbearers: Produce crop in May and again in late-summer to early fall. Some berries produced in summer. P Day-Neutrals: Like everbearers but more fruit during summer. However, flower production inhibited above 70/F.

  9. Planting Preparation P Choose sunny, well-drained site and mix in organic matter

  10. Planting Preparation P Choose sunny, well-drained site and mix in organic matter P Fertilization <Fertilize according to soil test <Or apply 10 to 12 pounds of a 10-10-10 fertilizer per 1000 square feet and work into soil with organic matter

  11. Planting Procedures P String line so planting is straight P Keep roots moist

  12. Planting Depth P Too shallow and roots may dry P Too deep and may smother crown

  13. Spacing Plants P Space plants 18 to 24 inches apart in rows 3 1/4 to 4 feet apart

  14. Strawberry, Water In After Planting P Use about 1 cup of water per plant

  15. Keep Planting Watered Can use trickle irrigation or overhead watering

  16. Remove Blossoms the First Year P Plant has a limited amount of energy P Energy needs to go into runners rather than fruit

  17. Runner Spacing P Runner spacing. Space plants 4 to 6 inches apart. Extra runners should be removed, if possible. Keep bed width to 12 to 18 inches PI usually thin runners in August

  18. Fall Care Strawberries set fruit buds as the days shorten in September and October. P Fertilize in late August to early September. Apply about 3/4 to 1 pound of a 12-12-12 fertilizer per 25 feet of row. P Keep planting watered and weeded. P Fall care determines the size of next year’s crop!

  19. Preparing the Crop for Winter P Make sure the strawberries go into the winter with the soil moist. P Mulch the plants when weather turns cold; normally sometime between Thanksgiving and mid-December.

  20. Mulching P Not trying to protect the plants from cold as much as from alternate freezing and thawing. P If you use straw, should require about 1 bale for every 100 feet of row

  21. Second and Succeeding Years Care Spring P Pull mulch off when new growth reaches 1 to 2 inches (usually in March). Remove just enough mulch that new leaves can poke through. P Don’t fertilize! Too much nitrogen makes the berries soft and prone to rot. P Irrigate as needed. Water deficiencies can lead to small berries.

  22. How to Protect Blooms P Remember first berries are king berries; the largest berries of the season. P If a frost is forecast, protect blooms by: <Covering planting with blanket <Running overhead irrigation all night until ice is melted

  23. Bloom and Harvest Manhattan Area P Bloom usually starts about mid-April P Harvest starts the second week of May P Harvest usually lasts about 3 weeks P About 1 quart of berries per plant if well cared for

  24. Renovation Done immediately after harvest to rejuvenate plants

  25. Renovation First Step: Mow off leaves

  26. Renovation First Step: Mow off leaves

  27. Renovation Second Step: Gather and Discard Leaves

  28. Renovation Third Step: Fertilize with 1 pound 10-10-10 per 25 feet of row

  29. Renovation Fourth Step: Narrow row to 10 inches

  30. After Renovation P Keep planting watered. P Plants should have recovered in about 2 weeks. P Fertilize again in late August to early September. P Mulch for the winter after several hard freezes. P Replace planting when production falls off or every 3 to 4 years.
