Transcripts - Native Plant Establishment - Late Summer

  • 1.  Timing of winter/fall planting Water needs vs. water use Faster establishment with lower maintenance TRWG-Z over hand- watering
  • 2.  Clarify potential benefits of TRWG-Z over hand-watering Determine if single application ( or12 weeks of continual moisture) could successfully establish plants Determine if photosynthesis prior to dormant season would have substantial benefit to plant establishment Define water saving using TRWG-Z
  • 3.  TRWG-Z, (carboxymethylcellulose cross-linked polymer) • Potable water  City of Santa Rosa, CA • Zinc Sulfate  essential to many enzyme systems in plants  contributes to production of growth regulators  most available form of zinc to plants • Glacial Acetic Acid  naturally occurring auxin  induce elongation in shoot cells  improve uptake of minerals
  • 4.  Species • Quercus agrifolia • Quercus lobata Planting times • August 4, 2009 • September 2, 2009 • October 2,2009 Container size • D-40 Climate-Mediterranean 10- 10-Month 9-Aug 9-Sep 9-Oct 9-Nov 9-Dec 10-Jan 10-Feb 10-Apr 10-Jun 10-Jul Mar MayHigh 102°F 101°F 87°F 80°F 65°F 62°F 71°F 81°F 82°F 83°F 97°F 92°FLow 47°F 40°F 38°F 30°F 21°F 32°F 34°F 33°F 34°F 35°F 45°F 45°FPrecip 0.11 in. 0.49 in. 1.81 in. 4.31 in. 4.50 in. 6.25 in. 6.08 in. 4.71 in. 1.67 in. 0.83 in. 0.19 in. 0.06 inwww.accuweather.com/us/ca/santa-rosa/95401/forecast-month.asp

  • 14.  Late summer planting appears to allow sufficient photosynthesis resulting in ample carbohydrate storage for spring plant growth Zinc and Glacial Acetic Acid contribute to the production of essential growth over potable water with no nutrients Using TRWG-Z contributes to overall water efficiency No plants received water after 12 weeks -1 fatality-continual moisture appears necessary
  • 15. TRWG-Z HAND-WATER Per Plant  Per plant • 2.5 gallons at planting • 2.5 gallons per week • 1 Quart of TRWG-Z for 12 weeks = 30 • 12 weeks = 2.75 gallons gallons Water saving per plant: 92%
