will cost less than $3.00 per mixed gallon of spray.
now lets say the first spray fails and you have to spray twice; the question you then have to ask yourself is whether or not the evergreen is worth $5.00 or $6.00 of mixed spray to save? any of my trees would be worth 1-2 gallons but this is a personal decision so i can’t make that call. but if you weigh the costs versus what might happen if you don’t spray, you should be able to make a decision and take action one way or the other.
