  1. Intensive Organic Container Gardening Pattie Louche Lisa Harty and Lisa Stefanick

  2. Soil Preparation • Reasons not to use outside dirt from your yard. • Too sandy, too much clay, too heavy • No nutrients • Weeds, seeds, diseases, insects • Chemical fertilizers may be present • Reasons not to use soilless mix • Too light, not strong enough to support plant roots • Sterile and contains very few nutrients • Small amts of synthetic fertilizers and wetting agents-not organic

  3. Read the label • “Certified organic” • Approved by OMRI (Organic Materials Review Institute) • Some peat moss or limestone treated with prohibited material • Unreliable amounts of compost- 20-50% • Should contain only natural plant and animal derivitives

  4. Recipes for soil mix • 1 part peat moss or mature compost • 1 part garden loam or top soil • 1 part clean builder’s sand or perlite • Or • ½ cubic yard peat moss • ½ cubic yardperlite • 10 lbs bone meal • 5 lbs ground limestone • 5 lbs blood meal *note if using own compost make sure it is mature (made last summer for this spring planting)

  5. Soil testing • Soil testing ahead of planting will let you know what to add • Saturated Media Extract test • Offered by most university and commercial horticulture labs • 1-3 week turn around

  6. Fill pot ¾ full and add organic fertilizer to top 3 inches of soil and you are ready to plant!

  7. Containers • Types • Preparation • Sizing for particular plants • How to fill with the proper blend of soil/organic matter etc…P/K/N

  8. Plant combinations • 5 gallon: tomato/peppers/eggplant or tomato/cilantro/onion (successive planting) • 2 gallon: strawberry/spinach/chamomile • 1 gallon: cabbage/garlic/green onion or lettuce/cukes/green onion (successive planting)

  9. To fertilize or not? • Soil testing before planting is your key to what your garden needs • Increased demands from intensive practices • Use organic fertilizer, fish emulsion, worm casting or tea, compost and/or compost tea • Increased risk of overfertilizing – water thoroughly each and let drain through • Adequate drainage is a must! • Clump containers together-

  10. Pest and critter control • Diligence is key! Prevention and early treatment is a must • Beneficial bugs, partner plantings • Most pests are variety or crop specific • Keep on balcony or porch (keeps bunnies and squirrels away!) • Blast with water, soapy water, Neem or horticultural oils or cover with Remay cloth

  11. Harvesting • Trellising, supports, training upward or trailing downward, interplanting, successive planting, rotating plants, replacing with new seedlings often help prevent bolting and always having something new to grow and eat. • Themes (Italian, Greek, salsa…) and partner plants • Enjoy!
