Trees and Shrubs Irrigation management is critical during the summer on landscape trees and shrubs. We are seeing across central Louisiana the adverse affect of drought on trees and shrubs. Water conservation in the landscape is an important topic. Careful management can improve plant performance and still conserve moisture. Establishment of a drip irrigation system for shrub irrigation may be a wise investment.
Organic matter increases the water holding capacity of a soil.
Mulching reduces water demand by as much as 40 percent. Crowding plants increases competition for water. Many times shrubs are not planted at their ideal spacing between plants. Weeds compete with your desired landscape plants for water. Transplant tomatoes in mid July through mid August for your fall crop.
