Growing Texas Olives Stephen Janak

In this episode I discuss the concept of plant available water in the soil and estimating that available water by feel and appearance. I then talk about using this method to best irrigate newly-planted trees and young, non-bearing orchards. Although the second half of this episode is geared towards new and young trees, the information presented applies to everyone and is excellent knowledge to have even for mature orchards.

In this episode, I announce the upcoming UC Davis Master Milling Course, discuss an idea to bring together olive people from across the southeastern US, and review two scientific papers. The first paper studied the effects of root pruning on 2-year-old olive trees with interesting results. The second paper studied the potential timing of floral induction; basically, if new buds are produced on the tree from May through October, is there a point after which newly-formed buds will not become floral buds next year? This study has implications for Texas and is welcomed information.

In this episode I discuss some basic irrigation system maintenance practices that often seem to get overlooked. I also discuss ways to periodically evaluate your irrigation system so that you know it is operating correctly and applying as much water as you think it is. This is the first step in excellent irrigation management. In future episodes we will talk about estimating water needs and scheduling irrigation, but you must understand all of the material in this episode before you can effectively and efficiently manage your irrigation in the olive orchard.

This episode will be the first in a series of episodes dedicated to irrigation. It is now hot and dry in Texas, and proper irrigation of olives is crucial. Many experienced growers and experts agree that irrigation management is likely more important than fertilization; so, are you doing it right? In this episode we just start to scratch the surface of understanding proper irrigation of an orchard by re-thinking what it means to apply water to an orchard. 

In Episode 16, we consider what is happening in the olive orchard during May, and I discuss what managers should be thinking about or doing during this time. I also answer questions that I received recently about caterpillar pests and ants. 

This is a long one, and yet it doesn't cover everything there is to know. Maybe listen to this one in two or three sittings. I discuss the fundamental knowledge needed to make weed management decisions in the orchard.
