Jon hill turf | Why and How design a Lawn
- 1. Welcome
- 2. Lawns
- 3. Purpose of lawns • Ornamental • Recreation • Utility
- 4. Planning a lawn • Location – Soil type, moisture, light, surrounding plants, zone • Use • Type of grass • Time, cost of maintenance • Time, cost of installation
- 5. Location
- 7. Location
- 9. Types of turfgrass • Regional adaptation of species – Cool season grasses • Grows well at 60-75F • Growth ceases over 80F • Intolerant of heavy shade – Warm season grasses • Grows well at 80-95F • Dormant in winter (brown)
- 10. Grass types
- 11. Turfgrass adaptation maps • 1&2 – cool • 4 – warm • 3 – transition zone
- 13. Turfgrass adaptation zones ZoysiaTall fescue Centipede
- 14. Uses • Zoysia – prickly blades • St. Augustine – intolerant to traffic & compaction
- 15. Resistance to wear • Traffic tolerant – Cool season: Tall fescue – Warm season: Bahia, Bermuda • Traffic intolerant – Saint Augustine grass
- 16. Grass texture
- 17. Growth habit • Many cool season grasses are bunching (can get clumpy)
- 18. Competitiveness (aggressiveness) • Colonizing species desired on slopes • Aggressiveness depends on environmental conditions • Aggressive grasses – Zoysia stolons are very aggressive – can grow under edging – Bermudagrass
- 19. Maintenance • High maintenance types – Dethatching required – Disease & insect susceptible – Frequent mowing – Warm season: Bahia, bermuda – Cool season: bentgrass, bluegrass
- 20. Maintenance • Low maintenance – Resistant to drought & diseases – Cool season: Tall fescue – Warm season: centipede, zoysia
- 21. Shade • Many grasses are shade intolerant • Shade tolerant types – Cool season: red fescue, chewing fescue – Warm season: centipede, Totality
- 22. Lawn shapes
- 23. Installing a lawn • Seeding – Soil preparation • Nutrient, pH testing (6.5) • Amend for drainage, soil texture • Remove debris, coarse material • Roll • Fertilize (starter fertilizer – high P) • Weed control, if desired
- 24. Buying grass seed • Straight – one species • Blend – 2 or more cultivars of same species • Mixture – 2 or more species – Temporary species for quick establishment – Permanent species (>60% of mix)
- 26. Time to sow • Cool season: late summer/early fall • Warm season: late spring
- 27. Seeding rate (~1oz/sq. yd.) • Desire a dense lawn • Rate varies by grass type • Seeding devises
- 28. Mulching seed beds • Wheat straw most common – Protect seed from birds – Prevent washing away – Conserve moisture – Control erosion – Roll
- 30. Hydroseeding
- 31. Sodding • Instant coverage • Least problematic • Most expensive • Can install anytime
- 32. Laying sod • Use immediately • Tight fit • Stagger pieces • Roll
- 33. Plugging • Sod plugs (1.5-2”) spaced 6-12”
- 36. Lawn maintenance • Mowing • Irrigation • Fertilization • Weed control • Disease and insect pests • Aeration/scarification (dethatching) • pH correction • Leaf removal
- 37. Lawn maintenance • Mowing height
- 38. Mowing principles • Never remove more than 30% of blade length • Mow when dry – Disease suspectibility – Weight of cuttings • Keep blades sharp • Alternate mowing pattern
- 40. Mowers • Bagging vs. mulching
- 41. Edging
- 42. Trimmers/edgers
- 43. Watering • Most grasses require 1” water per week • Soil moisture should reach 4” depth – Light watering may encourage upward root growth • Water in mornings or evenings (mornings preferred)
- 44. Irrigation
- 45. Fertilizing • Follow recommendations for lawns
- 48. Fertilization • Broadcast vs. drop spreading • Liquid fertilization
- 49. Disease and pest control • Disease problems • Insect problems • Turf grass pests
- 50. Grub damage
- 51. Weed control • Pre-emergence selective herbicides (broadleaf herbicides) • Post-emergence selective herbicides • Forms: granulars, liquid sprays • 2,4-D popular
- 54. Aeration
- 55. Aeration
- 56. Topdressing
- 57. Lawn or groundcover? • Turfgrasses establish poorly in deep shade • Turgrasses may be difficult to establish on steep banks
- 58. Lawn alternatives • Blue rug juniper • Dwarf mondo grass (shade) • Chamomile, thyme
- 59. Chamomile as a lawn alternative
- 60. Thyme as a lawn alternative
