| Leaf Spots and Leaf Blights |
|---|
* Leaf spots and leaf blights are cause by numerous fungal pathogens, but the symptoms they cause are relatively similar for all of them.
* All palms should be considered hosts for leaf spots and leaf blights, especially in the juvenile stage.
* Leaf spots initially start as small, water-soaked lesions that turn various shades of yellow, gray, reddish-brown, or black. These lesions may be surrounded by a halo or ring of tissue that is a different color.
* Leaf spots can increase in number or size such that large portions of a leaf blade are diseased.
* Sanitation and water management are critical for leaf spot and blight disease management. Injury prevention and good nutrition are part of the overall care strategy.
* Fungicides may be useful as part of an integrated management program, though should never be the sole componenet in treatment.

| Codominant Tree Hazards |
|---|
| Codominant stems and large branches with included bark may be the single most dangerous condition posed by trees in urban landscapes. The occurence of included bark means that a collar is not present around the base of a branch, the branch is poorly secured to the trunk, and decay may develop above and below the crotch. Proper pruning techniques may help to avoid this situation. We at westenberger follow standards to perform the proper pruning to help avoid these common problems. If you see that Mechanical support may be needed in trees on your property. Do not delay, call us today. |

| Fertlizer Ordinances |
|---|
| You may have read that most of the county and local city regulations are changing regarding fertilization. They are restricting the application regulations of fertilizer. They have implemented a ban for applying fertilizer during the "rainy season". This ban is from June 1st to September 30th. Please check your local regulations before applying fertilizer during these months. We have adjusted our schedules to accomodate these banned time periods to be ahead of the compliance effort. |

| Mangrove Trimming |
|---|
| Time to trim the mangroves. Mangrove trimming is permitted from March 1st to November 30th. We are a Registered Mangrove Trimmers for Pinellas County. Mangroves are tropical trees that grow in calm intertidal areas where temperatures do not usually drop below freezing for prolonged periods. They provide many important benefits to the residents. They control shoreline erosion, protect homes from wind and storm damage, maintain water quality, create critical habitat and nursery areas, support recreational and commercial fishing, and create a healthy natural environment for all residents and visitors to enjoy. |

| Cold Damage to Palms |
|---|
| Palms that were severely damaged during the recent cold weather should be watched carefully during the subsequent spring and summer seasons. Damage to embryonic leaves within the bud may not show up until those leaves emerge. This can take as much as 6 months to a year. If the leaves emerging in the spring and summer months are deformed, partially, browned or otherwise abnormal, this may be indicative of this type of damage. In most cases, the palm will grow out of this later in the season. (Referenced from UF/IFAS) |
