  1. Annual Flowers - Bed Preparation, Maintenance and Design David Hillock Assistant Extension Specialist/ Consumer Horticulture

  2. Advantages: • Versatile, sturdy, & relatively cheap • Easy to grow • Produce instant color • Provide season long color and interest!

  3. Disadvantages: • Must be planted yearly • involves some effort & expense • Must be dead-headed for continuous bloom • Some look disreputable by late summer

  4. Temporary ground covers, Uses:

  5. Uses continued: • hanging baskets,

  6. Uses continued: • containers,

  7. Uses continued: • bedding plants,

  8. create interest or direct the eye, Uses continued:

  9. Uses continued: • cutting gardens, dried flowers , etc.

  10. Plant Selection Cultural Considerations: • hardiness • soil & moisture conditions • degree of sun or shade • maintenance

  11. Aesthetic Considerations: • size • form: • spreading, round or oval, vase, pyramidal, columnar • texture • color

  12. Bed Preparation: • Choose a suitable site: • i.e. - sun, shade, wet, dry • close to water source • away from shallow rooted trees and shrubs • compete for water and nutrients

  13. Prepare site by: • removing debris • remove/control weeds • glyphosate • first season devoted to weed control • check & adjust drainage • Raised beds may be necessary

  14. Soil tests are recommended! • determine proper amounts of fertilizer to apply • incorporate P & K into bed if needed • often need only nitrogen

  15. Amend soil with organic matter • incorporate 3-4” of composted organic matter • spade or till in 8-12” deep • improves soil aeration • improves drainage • encourages healthier root system • easier to plant and manage

  16. Shape bed by slightly raising or mounding towards the center or back • provides better drainage • positions plants so they can be viewed more easily

  17. Plant while soil is moist - not saturated • Plant during cooler part of day - evening • Water in immediately • Apply light mulch 1 - 2 inches thick • shades out weed seed • moderates soil temperatures • holds moisture

  18. Maintenance: • Water regularly • Fertilize based on soil tests • Daily walk through to monitor for problems • Remove pests by hand or mechanically • Use insecticides/fungicides only when needed

  19. Maintenance cont. • Weed control is best done by: • Use of mulch • Hand pulling • Shallow cultivation

  20. Maintenance continued: • Weed control with herbicides • Preemergence herbicides • Treflan – Preen, others • Post emergence for grassy weeds • Sethoxydim – Poast, Grass-getter • Fusilade – Grass-b-Gone

  21. If no soil test is taken: • Apply two pounds of 5-10-5 per 100 sq. ft. at planting • Apply another one pound at six week intervals throughout the growing season.

  22. What to look for when buying: • The plant should be: • rosette-like - short, stocky, leaves arranged in a rosette like pattern, vs. tall and leggy with leaves spaced out across stem • healthy looking - deep/bright green, firm, lustrous; not yellow, brown, twisted, curling, sticky, etc.

  23. The plant should: • have healthy roots - white, fuzzy, abundant; not brown, slimy, or wrapping in circles, or too few • be moist - but not soggy; and not water stressed • not be in flower - energy directed towards root formation

  24. Design Concepts • Formal • Informal

  25. Design Concept: A Mountain Meadow Effect – Informal • Do not worry about straight rows or spacing • plant them where they land • Use other landscape plants as part of design • shrubs, perennials, ground covers, etc.

  26. Aesthetic Critique • Personality - Character • Is it apt: exactly suitable to its surroundings?

  27. Spontaneity • Is it free flowing; not labored, loose but confident, happy, buoyant? (negative example: solid lines and boarders)

  28. Color • Do color combinations have crisp oppositions, smooth analogies?

  29. Color continued: • Use white near patios - shows up well at night • Use white and gray as separators of conflicting colors • Warm colors – red, orange, yellow gives illusion of smaller space • Cool colors – blue, green, violet gives impression of openness and space

  30. Structure, Form, & Texture • Are there clear contrasts, effective relationships, harmonic rhythms?

  31. Neighborhood • Does the flower bed integrate with neighboring flower arrangements?

  32. Natural Environment • Are varieties used ecologically nested to the sun/shade, sand/clay, wet/dry, cool/hot, and endemic disease facts of life for location?

  33. Practical • Maintenance: Is it maintainable? (dead-heading) • % Risk: Experiment with less than 10% of entire commitment. Repeat past success! • Execution: Can it be simply planted?
