1- check the irrigation coverage yourself; make sure it is getting watered<br>2- You set the system to irrigate that area with 1/2 to 1 inch of water<br>3- Immediately after irrigation, probe soil to check depth of moisture. If it is still dry, then you probably have one or both of two problems: excessive thatch or hydrophobic soil.<p>Thatch is often the problem at the crest of a hill in full sun most of the day. For thatch, aerate and also apply Primer from &lt;a href=&quot;;&gt;Aquatrols&lt;a&gt;.<p>For hydrophobic soil, apply Primer at label rated intervals. Have actually seen a large area of hydrophobic sandy soil that, once dried out, will pool water on surface and be bone dry under the pool. Primer will break the surface tension and allow water penetration, but must be applied at regular intervals (6 weeks I think).<p>----------<br>Jim<br>North central Indiana
