  3. Container Vegetable Gardening

  4. Introduction Why Container Gardening? • No land • HOA hassles • Easy to get started • Close to the kitchen • Deer are not a problem

  5. Growing Advantages • Perfect for everybody • No digging or tilling • Weed free • Inexpensive to start up • Overcomes some common garden complaints • Container location • Plant protection • Season extension

  6. Getting Started • A little bit of room • Sunlight • Containers • Growing medium • Water • Nutrients • Tender loving care

  7. Container Location • 8-10 hrs. sun for fruiting crops • 6 hrs. sun for cool season crops • Access to water - smaller containers will need water every day • Placed on any level space • Be careful of microclimates • The water that drains from containers can stain concrete and wood decking • Large containers are heavy • 20-inch container = 100 pounds

  8. Container Types • Plastic • Wood • Clay • Free • Recycled • Practical • Expensive • Commercially produced

  9. Self-Watering Containers • “Self-watering” containers are a relatively new gardening concept. Instead of drainage holes in the bottom, these containers have an overflow hole on one side. The growing medium sits on a perforated platform directly above a water reservoir. In most cases, water is wicked up from the reservoir into the medium. • Self-watering containers conserve water and nutrients • Commercial self-watering containers can be expensive • You can make your own. Search GIEI website for containers

  10. Self-Watering Containers

  11. Self-Watering 5 Gallon Bucket

  12. Homemade Salad Table™ • The Salad Table™ HGIC pub 601 • Great for growing shallow rooted plants • Legs of any length, set it on saw horses or put wheels on it for mobility • Comfortable waist level gardening • Three compartments for succession gardening • Build it deeper for plants like beans, beets, kale

  13. What’s the “Dirt” on Growing Media? • Supports plant’s root system • Supplies nutrients • Permits drainage • Needs to be light and fluffy

  14. Growing Media • Garden Soil • Heavy • Bring in weed seeds and soil diseases • Doesn’t drain well in containers • Commercial Soil-Less Mixes • Excellent • Lightweight • Drains well • Holds water and nutrients • Proper pH • Examples of soil-less mixes are: ProMix™, ReddiEarth™, Jiffy Mix™, and Sunshine Mix™

  15. Stay Away From • Top soil • Planting soil • Planting mix • Potting soil • Mixes • containing sedge peat, wood mulch or bark fines • that are heavy or gritty • have very fine particles

  16. Adding Compost to Media • Highly recommended • Adds additional slow release nutrients • Increases water and nutrient holding capacity of media • May have to add perlite to lighten mix • If you don’t have compost, LeafGro™ is the next best commercially available product.

  17. Compost • Compost contains all the major and minor nutrients that plants need for good growth. This makes it an excellent substitute for sphagnum peat moss, which has very few nutrients (although it does hold water better than compost). • Composting effectively recycles the nutrients from gardens, landscapes, and farms, thereby reducing nutrient pollution of waterways. However, fertilizing is still necessary because the nutrients in compost are released slowly and are usually not sufficient for an entire season. • Vegetables, herbs and flower plants can be successfully grown in 100% compost or leaf mold. They have particles of various sizes which causes them to drain well.

  18. Media Mixtures • Some good media mixtures for container vegetables are: • •90% compost or LeafGro + 10% perlite • • 100% soil-less mix • • 50% soil-less mix + 50% compost

  19. Happy Roots • Watering needs vary depending on • container size • ambient temperature • wind • sunlight • humidity • type of plant and its size • Media in container should be kept moist at all times but not soggy • Most containers will need to be watered daily in the summer • Use a water breaker or watering can for soft flow

  20. Fertilizers • Containers require regular fertilization • Water soluble fertilizers • Good rule of thumb is every two weeks for water soluble fertilizers • Immediately available to plants • Organic varieties are ready available • How much and how often depends • Slow-release fertilizer • Inorganic such as Osmocote • Organic – blood meal, worm castings, etc. • Always follow label instructions • Excess fertilizer can harm and stunt plants

  21. What Can I Grow • Just about any vegetable or herb! • Popular, easy container crops: salad greens, peppers, eggplant, tomatoes, beans, chard, beets, radish, squash and cucumbers. • More challenging crops include melons, corn, potatoes, and sweet potatoes. • Look for “bush” or “dwarf” varieties , esp. tomatoes, cucumbers, squash. • The key is to experiment.

  22. Container Depth Matters • Match container depth to plant size • 4-6 inches: greens, small herbs • 8-12 inches: beans, beets, large herbs • 1-3 gallons: green onions, chard • 4-5 gallons: cucumber, eggplant, beans, broccoli, patio tomato, pepper • 15 gallon full size tomato

  23. Planting Time • No pebbles, gravel, or rocks unless you need the weight to prevent tipping. • Cover drainage holes with fiberglass screen or other material • Thoroughly work water into the growing medium • Fill container to inch or so of top of container. • Don’t compact media • Follow seed packet directions for planting, spacing, and care. • Plant seedlings (except tomatoes) at same level as they were growing in pot or six-pack. • Tomatoes can be planted deeper, for stronger root growth.

  24. Make Attractive Containers • Mix herbs and annual flowers in with the vegetable plants. • Herbs such as lavender, thyme, oregano, marjoram, and chives require a loose growing medium, and dry conditions. • Keep containers together to increase humidity and water retention

  25. Keep those plants growing! • Succession plant – spring - lettuce or spinach, summer - pepper , beans or cucumbers fall -kale, lettuce or broccoli raab to finish out the season. Don’t forget to continue to fertilize each crop! • Trellis tall or climbing plants • indeterminate tomatoes • pole beans • cucumbers • Move plants around if containers are portable to maximize sunlight (for heat-loving crops) and shade (for summer-grown salad greens).

  26. Planting & Care Diagnosing Plant Problems • Container grown plants are subject to the same insect and disease problems as garden grown plants, but container gardeners tend to have fewer soil related problems. • The biggest causes of plant problems are lack of water and nutrients, and overcrowding. Plants can also suffer root rot from too much water, especially if the growing mix does not drain well. • Go to plantdiagnostics.umd.edu for additional help in diagnosing vegetable problems.

  27. Season’s End • Compostthe plant and soil from the pot. • Do not reuse the same soil for a second season • Infected soil or mix will spread disease into the second season unless it is properly composted • Properly composted planting media can be reused. • Store pots to prevent freeze damage
