Summer Woes


This summer has been challenging! Copious amounts of rain started us off with tremendous growth both in lawns and landscaping. Let us not forget that cold temperatures during this past winter affected many plants around the landscape. I am still seeing palm trees around the county that have not fully recovered from the freezing temperatures experienced this past winter. Now we are challenged with higher than usual heat and humidity, which creates many challenges for homeowners. The key to surviving a hot humid summer in the coastal bend is to water. However, that being said, high humidity can increase the incidence of fungus in our lawns and on landscape plants. Also, I am noticing high populations of insects. Several things should be considered when combating common problems in our landscapes:
  • Water early in the morning - (4:00 a.m. - 7:00 a.m.) This decreases the amount of water left on the leaf surfaces. This moisture evaporates during the morning and does not allow for fungus growth. As moisture sits on top of leaves for a period of time, fungus has a better chance for survival and spread. The most important environmental reason for watering early in the morning is the fact that water is saved rather than lost due to evaporation.
  • Think EarthKind!--If you are battling insects or other plant problems, choose the least toxic. This, for instance, may be using a soap and water solution to spray mealy bugs on hibiscus plants. Also, using products that contain natural products that deter or disrupt insect feeding habits. (ex. fire ants- use products that contain the active ingredient spinosad.)
  • Lawn Fertilization - Is your lawn not staying green? This is a typical scenario with the amount of rain that has occurred this summer. Even though rain is very beneficial for lawn growth, major nutrients can leach out of the root zone and leave grass starving for food. Late August and early September can be a good time to give your turf a little boost of nitrogen and keep the lawn healthy. Just a simple 1/2 to 1 pound of nitrogen per 1000 square feet can perk up your lawn. Keep in mind to calculate your square footage of turf. If you need further help, you can go to the following site for a turf fertilization calculator.(http://aggieturf.tamu.edu/aggieturf2/calculators/fertsheet.html)
