April is an eventful month in the yard and garden. Insects are busily munching on their favorite plants. Winter annual flowers are still blooming, but will soon need replacing. The grass is growing lush, which means you will need to mow more often than you did during winter. And, it is historically our driest month.
Remember that we are currently under Phase II water restrictions, which means you can water up to twice a week if needed in Hillsborough, Pasco, and Pinellas counties. For more details, visit watermatters.org and click on the "Restrictions" button.

Oak leaf blister damage is usually temporary
Oak leaf blister is a disease we see nearly every spring. It develops during cool, wet weather, becoming epidemic at times and infecting almost every leaf on the tree. While the blisters may be unsightly and cause excessive leaf fall, this disease seldom causes permanent damage. Visit pinellas.ifas.ufl.edu/home_landscape/documents/oakleafblister.pdf for more information about oak leaf blister.

Those majestic evergreens do shed their leaves
Magnolia trees are called broad leaf evergreens but they do shed their old leaves during spring. These old leaves turn pale green or yellow and drop. Trees do not become entirely bare. Occasionally a magnesium or iron deficiency will cause yellow leaves but they have a distinctive pattern that can be identified easily.
