  1. Nursery Production Competencies 33.00-36.00

  2. What is Nursery Production? • The growing of plants in controlled environments (or nurseries). • Nurseries are places where plants, shrubs, and ornamental trees are grown for transplanting into landscape areas.

  3. Field Grown vs. Container

  4. Field Grown vs. Container • Field grown production is being replaced by container grown plants because there is less shock to the plant. • Plants are easier to move. • Retailers can keep plants longer before selling • Insects, diseases, fertility and pH are easier to control in uniform media.

  5. Field Grown vs. Container • Container grown plants have some disadvantages such as • requiring more water • becoming pot-bound • requiring winter protection for cold climates • having a higher start-up cost.

  6. Field Grown vs. Container • Types of plants grown in containers vary from ground covers to trees • Proper selection of containers should include several considerations such as • Cost • Durability • Appearance • Insulation value to plant roots • Shape • Drainage • Size

  7. Growing Container Plants • Either sell or transplant to a larger container when the plant reaches maximum recommended size for the current container.

  8. Potting Nursery Plants

  9. Potting Nursery Plants • Growing mixes (media) should provide adequate drainage and aeration. • Container media must be more porous than media for field-grown crops.

  10. Potting Nursery Plants • Space plants so that the tips of the branches almost touch those of other plants. • Containers will have to be moved as plants get larger.

  11. Potting Nursery Plants • Place plant in the center of the container if only one plant is used. • Evenly space the plants in the container if more than one plant is used.

  12. Potting Nursery Plants • Plant in containers at the right depth • Planting depth varies depending upon the type of plant.

  13. Watering

  14. Watering Nursery Plants • Water as needed to grow quality plants.

  15. Tips on Watering • Watering is more important for container grown plants than field-grown plants because roots can go no deeper or spread any wider than the container. • Plant containers are above the ground and will dry quicker.

  16. Tips on Watering • Plants should be watered until the water runs through the hole in the bottom of the container. • A gallon container needs about a pint of water at each watering.

  17. Factors that Affect Watering

  18. Weather • Plants require more water in dry, windy, hot weather

  19. Plant Growth • Plants need more water in active growth and flowering stage

  20. Media • More porous mix requires more watering

  21. Kind of Plant • Broadleaf evergreens require more water than narrowleaf

  22. Size of Container • Small ones dry out faster

  23. Type of Container • Fiber or pressed paper dry faster than plastic

  24. Surface Mulch • Mulch helps reduce need to water

  25. Fertilizing Nursery Crops

  26. Fertilization • Fertilization should be done on a schedule based on each type of plant grown • Some media have fertilizer in them • Nutrients have to be added to supply needs of growing plants

  27. Liquid Fertilizer • Liquid fertilizer used in watering is applied at a rate of 100 to 150 ppm (parts per million) of nitrogen • Periodic liquid fertilizing every two to three weeks is applied at a rate of 300-500 ppm nitrogen

  28. Slow-Release Fertilizers • Slow-release fertilizers such as Osmocote and Magamp are mixed in potting media

  29. Fertilizing Containers • Plants kept in containers more than one year require additional fertilizer at the rate of one teaspoon of 18% nitrogen for each gallon of container capacity and should be watered thoroughly after fertilizing.

  30. Tips on Fertilizing • Plants should be observed and fertilization changed as plant foliage shows a need for either more or less fertilizer.

  31. Pruning

  32. Why Prune? • To shape the plant • To make the plant more compact • To train the growth or form of the mature plant (central leader or many stems) • To remove dead or diseased parts

  33. Time for Pruning • The best time is immediately after planting and during the growing season • May be done in winter in temperate climates

  34. Methods of Pruning • Hand pruners • Electrical, battery, or gasoline powered pruners • Chemicals to kill buds of plants
