Nursery Production Competencies 33.00-36.00 Slide 2 What is Nursery Production? The growing of plants in controlled environments (or nurseries). 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. Nurseries are places where plants, shrubs, and ornamental trees are grown for transplanting into landscape areas. Slide 3 Field Grown vs. Container Slide 4 Field grown production is being replaced by container grown plants because there is less shock to the plant. Field grown production is being replaced by container grown plants because there is less shock to the plant. Plants are easier to move. Plants are easier to move. Retailers can keep plants longer before selling Retailers can keep plants longer before selling Insects, diseases, fertility and pH are easier to control in uniform media. Insects, diseases, fertility and pH are easier to control in uniform media. Slide 5 Field Grown vs. Container Container grown plants have some disadvantages such as Container grown plants have some disadvantages such as requiring more water requiring more water becoming pot-bound becoming pot-bound requiring winter protection for cold climates requiring winter protection for cold climates having a higher start-up cost. having a higher start-up cost. Slide 6 Field Grown vs. Container Types of plants grown in containers vary from ground covers to trees Types of plants grown in containers vary from ground covers to trees Proper selection of containers should include several considerations such as Proper selection of containers should include several considerations such as Cost Cost Durability Durability Appearance Appearance Insulation value to plant roots Insulation value to plant roots Shape Shape Drainage Drainage Size Size Slide 7 Growing Container Plants Either sell or transplant to a larger container when the plant reaches maximum recommended size for the current container. Either sell or transplant to a larger container when the plant reaches maximum recommended size for the current container. Slide 8 Potting Nursery Plants Slide 9 Growing mixes (media) should provide adequate drainage and aeration. Growing mixes (media) should provide adequate drainage and aeration. Container media must be more porous than media for field-grown crops. Container media must be more porous than media for field-grown crops. Slide 10 Potting Nursery Plants Space plants so that the tips of the branches almost touch those of other 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. Containers will have to be moved as plants get larger. Slide 11 Potting Nursery Plants Place plant in the center of the container if only one plant is used. 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. Evenly space the plants in the container if more than one plant is used. Slide 12 Potting Nursery Plants Plant in containers at the right depth Plant in containers at the right depth Planting depth varies depending upon the type of plant. Planting depth varies depending upon the type of plant. Slide 13 Watering Slide 14 Watering Nursery Plants Water as needed to grow quality plants. Water as needed to grow quality plants. Slide 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. 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. Plant containers are above the ground and will dry quicker. Slide 16 Tips on Watering Plants should be watered until the water runs through the hole in the bottom of the container. 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. A gallon container needs about a pint of water at each watering. Slide 17 Factors that Affect Watering Slide 18 Weather Plants require more water in dry, windy, hot weather Plants require more water in dry, windy, hot weather Slide 19 Plant Growth Plants need more water in active growth and flowering stage Plants need more water in active growth and flowering stage Slide 20 Media More porous mix requires more watering More porous mix requires more watering Slide 21 Kind of Plant Broadleaf evergreens require more water than narrowleaf Broadleaf evergreens require more water than narrowleaf Slide 22 Size of Container Small ones dry out faster Small ones dry out faster Slide 23 Type of Container Fiber or pressed paper dry faster than plastic Fiber or pressed paper dry faster than plastic Slide 24 Surface Mulch Mulch helps reduce need to water Mulch helps reduce need to water Slide 25 Fertilizing Nursery Crops Slide 26 Fertilization Fertilization should be done on a schedule based on each type of plant grown Fertilization should be done on a schedule based on each type of plant grown Some media have fertilizer in them Some media have fertilizer in them Nutrients have to be added to supply needs of growing plants Nutrients have to be added to supply needs of growing plants Slide 27 Liquid Fertilizer Liquid fertilizer used in watering is applied at a rate of 100 to 150 ppm (parts per million) of nitrogen 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 Periodic liquid fertilizing every two to three weeks is applied at a rate of 300-500 ppm nitrogen Slide 28 Slow-Release Fertilizers Slow-release fertilizers such as Osmocote and Magamp are mixed in potting media Slow-release fertilizers such as Osmocote and Magamp are mixed in potting media Slide 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. 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. Slide 30 Tips on Fertilizing Plants should be observed and fertilization changed as plant foliage shows a need for either more or less fertilizer. Plants should be observed and fertilization changed as plant foliage shows a need for either more or less fertilizer. Slide 31 Pruning Slide 32 Why Prune? To shape the plant To shape the plant To make the plant more compact To make the plant more compact To train the growth or form of the mature plant (central leader or many stems) To train the growth or form of the mature plant (central leader or many stems) To remove dead or diseased parts To remove dead or diseased parts Slide 33 Slide 34 Time for Pruning The best time is immediately after planting and during the growing season The best time is immediately after planting and during the growing season May be done in winter in temperate climates May be done in winter in temperate climates Slide 35 Methods of Pruning Hand pruners Hand pruners Electrical, battery, or gasoline powered pruners Electrical, battery, or gasoline powered pruners Chemicals to kill buds of plants Chemicals to kill buds of plants
