Camellias are a Panhandle favorite, as the flowers can highlight a landscape with bright, vibrant colors in fall and winter. However, spring time can bring about these colors in a negative way, in the form of leaf gall.
The camellia is native to Asia and brought to America in the late 1700’s. These plants have proven to be a dependable addition to the southern landscape with minimal care. When camellias are correctly planted and cared for, minimal disease problems arise. However, camellias can contract leaf spot, dieback, root rot and bud and leaf gall.

Leaf and bud galls are caused by the fungus Exobasidium vaccinia. The gall appears as thickened, waxy and enlarged leaves or buds during the cool spring months. One or several leaves on a single shoot may be affected. Once you’ve found infected leaves, no chemical control will be effective. Actually, no fungicide has been found very effective in combatting this condition. However, control can be accomplished in the home garden by simply pinching off and destroying infected leaves. Disease activity usually stops with warmer weather. A best management practice to curb infection is to reduce overhead watering during cool, wet weather periods of spring. Great news, this condition does not cause any long-term issues with the plant.

Fun camellia fact: The young leaves of the species, Camellia sinensis, are processed for tea, one of the world’s most popular drinks.

A healthy lawn is a joy to stroll, relax and play on. It can also be part of an environmentally friendly landscape. But, sometimes it can seem to be a mystery on how to achieve that lush, healthy lawn in the Florida environment. Since we have lots of sandy soils and experience long periods of warm and hot weather, many suppose that giving the lawn lots of water will help do the trick. Not so.

But what harm can it cause to give the lawn plenty of water all the time? Isn’t that a good thing? No! Overwatering your lawn can lead to the following problems:
Our lawns need, on average, about 1/2 to 3/4 “of water a week during the summer. This recommendation changes depending on soil type, shade, temperature, wind, and season. To figure out how long to run your sprinklers, watch this YouTube video from UF/IFAS.
We recommend running your automated system only when your lawn shows signs of needing water such as:

This month, recognized by the Senate and Florida’s governor, reminds diggers why calling 811 before all outdoor digging projects is important to your safety. Before installing a mailbox, fence, deck, garden or tree make sure to call Sunshine 811 to have underground lines marked. 811 is the free national number designated by the Federal Communications Commission. It notifies utility companies, who in turn send their professional locators to identify and mark the appropriate location of underground line with paint and flags in colors that identify the utility type. The following colors represent the seven various utilities: red, orange, blue, green, yellow, purple and white. To see which colors correspond with each utility go to: http://www.call811.com/faqs/default.aspx.
Hitting an underground utility line while digging can cause injuries, utility service outages to an entire neighborhood and damage to the environment. Failure to call before digging results in one unintentional utility hit every eight minutes nationwide. You could also be financially affected with costly fines and high repair costs.
Calling 811 in Florida is the law. At least two full business days before digging, do-it yourselfers and professional excavators must contact 811 by phone to start the process of getting underground utility lines marked. This is a free service. Be sure that all utilities have been marked before grabbing the shovel. Follow up on your one call ticket by contacting 811 again on the third day. For more information on Florida’s law, visit www.Sunshine811.com.
July’s hot summer weather has given way to August’s 31 days of what will likely be temperatures and humidity equally elevated and intense. Wishes for November’s cooler thermometer reading are already creeping into daily conversations. The lawns and gardens in Wakulla County have rains as a mitigating factor to counteract the wilting potential of normal to excessive temperature readings. Unfortunately the arrival of water from above is not on a set or easily predictable schedule.
Traditionally, summer is the wettest season in Florida, with more than half of the annual rainfall occurring during the June to September “wet season”. Florida’s highest average annual rainfall occurs in the Panhandle with averages exceeding 60 inches per year. The Pensacola and Tallahassee weather stations are listed among the ten “wettest” stations in the nation. Still, this pattern of seasonal precipitation can vary greatly between locations, years and even days. This variability often results in the need to water the lawn, landscape and garden. By following a few guidelines, you can produce the best results for plants under stress and conserve a vital and limited resource.
It is most efficient to apply water between 5:00 a.m. and 10:00 a.m. for several reasons. Only water that is in contact with roots can be absorbed by the plant. If water is applied after 10:00 a.m., a substantial portion of it will evaporate before it reaches the roots; more will then need to be applied and this resource’s productivity will be reduced. Never water late in the afternoon as evaporation will still be a problem, and wet turf and plants will invite a variety of fungal diseases to flourish as night settles.

In the case of landscapes and gardens, water should be applied only when the moisture in the root zone system has been depleted to an unacceptable level, usually by 1/2 to 2/3 of the stored soil-water. There are several ways to determine when the soil-water reservoir has been depleted beyond an acceptable level. The simplest method is a visual inspection of the turf or plants. Common symptoms of water stress include leaf color changes to a bluish-gray tint, footprints which linger long after being pressed into the grass and curled or folded leaf blades. Be sure the sprinklers are delivering water to the target area as water which misses the soil and is applied to hard surfaces such as driveways and sidewalks will be wasted. It also may pose an environmental problem in the form of runoff. Surface runoff that flows past the landscape will usually reach streams, ponds, or the Gulf of Mexico. If it picks up pollutants along the way, they too will reach the surface water bodies.
Over watering can be just as damaging as too little water. Excessive irrigation water can infiltrate the ground and reach groundwater aquifers. This issue is complicated when groundwater runs close to the surface. Excessive nutrients or pollutants can be discharged into surface bodies or move vertically into the deeper land layers. The connected springs and sinkholes in Wakulla County make the movement of surface water a common concern. Responsible and efficient irrigation will have positive effects far beyond the front yard.

Although we’ve received much-needed rainfall of late, it’s still a struggle to manage moisture levels in our Panhandle landscapes this summer. During wet summer seasons, one recurring issue is that watering plants too much can have as much of an ill effect as not watering enough.
Shallow rooted plants, as well as newly set plants can easily become water stressed. Some people lightly water their plants each day. With this practice, one is only watering an inch or less of the topsoil. Most roots are deeper than this. Instead of a light watering every day, soaking the plant a few times a week works better. A soil that has been soaked will retain moisture for several days. This is a very good practice for young plants. In contrast, some people soak their plants to often. This essential drowns the roots by eliminating vital oxygen in the root zone. This can also cause root rot. Leaves that turn brown at the tips or edges, as well as leaf drop, are displaying signs of overwatering.
The following are tips from the UF/IFAS Florida-Friendly Landscape Program. These tips will help conserve water by providing best management practices for your landscape:
