I recently had the good fortune to hear a seminar by Dr. Marc van Iersel, Professor, Plant Nutrition and Physiology, University of Georgia at UK. His work with annuals and some woodies is enlightening. During rapidly-induced drought plants are under measurable stress, but plants subjected to gradually-induced drought are able to acclimate. Dr. van Iersel's web site is informative and his grower-oriented and many of his research publications are available for viewing at: http://mvanier.myweb.uga.edu/ I particularly liked his site Fertilization in Greenhouses: an Introduction http://www.hortphys.uga.edu/fertilizer.html

Tom Priddy, UK Ag. Weather Center reported in a recent UK E-mail ...Bluegrass Joined Central in Severe Drought; East and West Remained in Extreme Drought... The latest Kentucky Drought status is available at: http://wwwagwx.ca.uky.edu/latest_drought.shtml Many of us were fortunate to attend the KNLA Summer Outing and hear Tom Priddy talk about the Spring freeze and the 2007 weather/environment. What a season I was out trying to collect seed and found that my prized Spicebush colony had dried up during seed development resulting in immature seed and dead leaves still on the trees that are now putting out new leaves and blooming.

Cicadas are coming: In 2008 brood XIV (17 - year) will appear statewide except Purchase and possibly Pennyrile areas. For more information see Drs. Doug Johnson and Lee Townsend's EntFact-446 Periodical Cicadas in Kentucky publication at http://www.ca.uky.edu/entomology/entfacts/ef446.asp ***FIX LINK*** Pesticides are listed in the publication but pesticide recommendation updates with additions and deletions to this 2004 publication can be expected from the Entomology Department as we get closer to the Summer 2008 emergence.

Jeremy Griffith, Extension Associate, has been searching for new sources of pine bark and in the process has investigated use of freshly harvested pine bark and the whole tree chips as a media versus the aged pine bark most in west Kentucky are using. He reports that there several differences between aged pine bark and fresh. Pine bark in general is preferred over hardwood bark because it contains less leachable organic acids and resists decomposition than some hardwoods. The characteristics of pine bark are dependent on the method of composting and age. Growing plants in fresh pine bark media increases competition for nitrogen. Pine bark will absorb or 'fix' ammonium nitrate so that it isn't available to the plant. As the pine bark is aged the C/N ratio is reduced dramatically. This causes the substrate to need less nitrogen, making the majority of N from fertilization available to the plant. Fresh pine bark averages 10%-15% available water while aged pine bark averages 25%-35% by volume. With age it becomes less water resistant and can absorb more water within each particle. The change in water holding capacity allows the grower using aged pine bark to irrigate with less frequency than if fresh pine bark is used. These characteristics make aged pine more desirable than fresh pine for west Kentucky growers.

This year will be in the top 15, actually top 3, driest years according to Tom Priddy, UK College of Agriculture meteorologist, who reported 10.41 inches for Precipitation(in) ranking for Kentucky for May through August 2007 for previous years see below.

1- 1936 8.34 | 2 - 1930 8.37 | 3 - 1913 11.33 | 4 - 1999 11.94 | 5 - 1925 12.38| 6 - 1964 12.45 | 7 - 1904 12.53 | 8 - 1988 12.67 | 9 - 1952 12.76 | 10 - 1911 12.77| 11 - 1902 12.94 | 12 - 1944 13.00 | 13 - 1921 13.07 | 14 - 1901 13.22 | 15 - 1914 13.33|

In another e-mail he wrote: How does this summer's heat and lack of rainfall compare with the past? A preliminary check indicated that this has been the 3rd driest May through August in the past 113 years. With only 10.41 inches of rainfall for the state so far from May to August 26th...The only drier May - August's were 1936 with 8.34 inches and 1930 with 8.37 inches. After this year's near record dry summer, the next driest was 1913 with 11.33 inches. Last Thursday's US Drought Monitor holds 73 percent of Kentucky in Extreme hydrologic drought. ...it's the 13th warmest May thru August in the past 113 years. WOW! Unfortunately, plants in the brown-tan landscapes of west Kentucky make all this seem obvious.

SNA Researcher's Conference 2007: Field grown trees did not respond to nitrogen source or even fertilizing with nitrogen in a study by Jim Robbins of Arkansas. Discussion about this presentation at SNA found that other university researchers had similar results. John Ruter found reduced foliar nutrients and root dry mass when container plants were fertilized above 2 pounds of nitrogen per cubic yard. Italian visiting researcher Piero Frangi found similar results to Ruter's: excess fertilizer lead to an increased shoot to root ratio (less roots) and less drought resistance. Richard Beeson has done work on container irrigation and spacing for years; his presentation on spacing showed results that a spacing of 0.75x (x = pot diameter) was most efficient. There were numerous papers on whole tree media; chipping whole pine trees and using the material as media. I cannot wait to get the CD sent to all SNA members with all the great research papers and posters that were presented this year.

The 2007 KNLA Summer Outing kept in the long tradition of successful Summer Outings with over 60 exhibitors, 200 plus attendees; standing room only for the interesting education presentations with good audience interaction; a great Paul Cappiello plant tour; Yew Dell tours and a good lunch.

The freezing temperatures, with a low forecast for 23oF Saturday or Sunday, are expected from April 4 to April 8, 2007. Flower and flower bud damage and possibly some new growth and even wood die back can be expected. Amy Fulcher wrote in Nursery Update #54 that the Degree Days for April 2, 2007 were significantly higher than for 2006. April 2, 2007: Lexington 290, Princeton 389. April 2, 2006: Lexington 130, Princeton 250. Wow! Plants are far advanced for this time of year and are not in a physiological state to tolerate freezing.

Dry Pesticide Rates for Hand-held Sprayers HO-83 by Joseph Masabni is a very helpful publication that takes into account that chemicals have different weights and densities and ready transfer of conversions to tablespoons per gallon does not work.

Once again Brent Wearren and crew at Wearren and Son Nursery have provided a great educational opportunity by hosting the winter pruning workshop, February 13th. It was a rainy cold day following other rainy days that made the fields impossible to drive in and very difficult for walking. Brent had the crew cut down trees from the field and bring them to a sheltered area for demonstration. Ultimately we did go to the field for a valuable pruning demonstration but equally important Brent shared that the pesticide manager would not be happy to see Brent's deep footprints in the clean area in the tree row because pre-emergent herbicide had already been applied and now there would be areas without the herbicide barrier. Interesting comments by Brent and his crew: when retraining the central leader with masking tape don't pinch the tape closed in between the new leader and the old leader as it will hold water and rot the new leader; when cutting a leader slope the cut to ensure water runs off; rake clippings into the mow lane so they are not in the tree row and covering the ground limiting herbicides getting to the ground target; Brent insists there be a 'œgame plan' for all pruning with the first year the most important; for winter-early spring pruning prune the fastest growing plants first; bleeders like maples and yellowwood are last even left til late spring-early summer; selecting the central leader is a pruning crew job, not a staking crew job; plants that may need staking such as oak, prune first then stake in order to get even branching; the obvious, but not always practiced - plants with a lower profit margin should not be a priority but a fast growing plant that is selling well like Autumn Blaze Maple should get special attention to guarantee a quality finished plant. These are just a few of the tit bits shared that make each and every pruning workshop of value and you have other people that have pruning responsibility sharing how they do it like Tom at Snowhill sharing his method of training buds to produce a new leader. You just have to be there!!! A special thank you to Amy Fulcher for organizing these events.
