Starting from Seed

You and your students will want to start some seeds in their permanent containers or beds, if you are raising crops that do not transplant well (such as beans, peas, cucumbers, melons, squash, carrots, beets, and radishes) or if transplanting them later on isn't an option. You may choose to sow other seeds in temporary containers, and later transplant them to larger containers or greenhouse beds.

Nutritionally Speaking

Plants require certain nutrients in order to thrive and grow. These are not actually food, but chemical elements or minerals that are vital to helping a plant use the sugars (the real food) that it produces during photosynthesis. Nutrients are normally found in soil, in decomposed organic matter such as compost, and in commercial fertilizers. The "macro-nutrients"--those required in the greatest amount by plants--include nitrogen, phosphorus, and potassium.

Growing Media

Soil found outside stores and releases nutrients, provides plant support, and creates passages for air and water. It contains living thing--bacteria, mites, and worms, as well as nonliving substances--small particles of sand and clay. Greenhouse soils need to be lighter than garden soils, because frequent watering tends to pack soil down.

Planting Options

Greenhouse Bed Gardening

Soil-filled greenhouse beds, near ground level or raised to 24 inches, are ideal for creating indoor planting habitats. Since beds (particularly raised) typically contain more soil than containers do, they promote good root growth.

Interplanetary Plants

(Photo credit: Ray Wheeler)No question about it--plants are vital to our existence here on earth. They provide us with the essentials of food, oxygen, and shelter. But have you ever stopped to think about how these benefits would translate beyond our planet?

Growing Kids in Accessible Gardens

Gardens are an excellent teaching tool for youth because they providing important hands-on learning activities and inspire kids to discover the wonders of their environment. These experiences are valuable for all children, but can be especially meaningful for children whose exposure to nature is limited, such as those with special needs. These kids face challenges and barriers in the traditional outdoor setting, and instructors and parents are often times hesitant to involve them in gardening activities.

Research Update: Do Youth Gardening Experiences Lead to Greater Educational Opportunities?

Educators who work with youth garden programs are quick to share the benefits they have observed, such as children who are transformed from hyperactive troublemakers in traditional classroom settings to eager and conscientious caretakers in the garden, and students who suddenly grasp connections between science and real life after participating in hands-on gardening experiences.

Community Gardener Jill Jones

Growing Bountiful Gardens and Community Pride

Jill Jones of Cedar Rapids, Iowa, had watched with dismay as her inner-city neighborhood of Wellington Heights--once home to grand old houses and tree-lined streets--declined into falling-down buildings; trashy, empty lots; and a haven for drug dealers, arsonists, and vandals.

Growing Healthy Futures

In many U.S. schools, statistics show that you’ll find children who are overweight and others wondering where their next meal will come from; many are not getting the right balance of nutrients in their diets or enough exercise. Research conducted at Texas A&M University supports the connection between kids’ food gardens and improved nutrition.

Plant of the Month: Tomato

Almost every school vegetable garden hosts tomato plants, and the ability to grow a handsome tomato earns a gardener the title of "green thumb." Tomatoes are a delicious staple of American cuisine, which is fortunate considering that they provide important vitamins, minerals, and cancer-fighting antioxidants. With fresh tomatoes on sandwiches and burgers, and processed tomatoes in pizza, salsa, and catsup, it's hard to make it through a day without eating a tomato or tomato-based product!
