I hope you have already read our section on watering pecan trees. If not, there is a link above to take you there. Watering and fertilizing pecan trees go hand in hand, and utilizing sufficient quantities of either offset the need to over-apply the other. This knowledge offers you the opportunity to make some decisions that might make the difference in making a profit or going 'in the hole' from year to year. Before we continue, I insist you read the section on Zinc application just as soon as you've finished this page. Next to watering your pecan trees, there is not a more important chore than applying zinc to your pecan trees...even more important than applying fertilizer!
I've not typically been an advocate of over-fertilization throughout the years, basing my beliefs that the world's greenery survived for millions of years prior to the introduction of fertilizers, and did quite well without them. However, fertilizer does have its place in pecan production. I'm going to start by taking a look at the lawn, yes sir, the front yard. For years and years, I was adamant that my lawn did not need commercial fertilizer, and on a DAILY basis throughout each summer, I drug a sprinkler around the yard to keep it green. One spring my wife brought home a bag of lawn fertilizer and a spreader and told me to fertilize the grass. (That's how it works, isn't it.) Throughout that summer, I found there was little need to water more than once a week, and as a matter of fact, there was little time to water between the bi-weekly mowing chores of our lush green lawn. I now fertilize our lawn yearly.
