If you live in Temple, Killeen, or anywhere in Central Texas, you know about cedar fever. From late December through February, mountain cedar (Ashe juniper) trees release massive clouds of pollen that turn the air hazy and make roughly 25% of the population absolutely miserable. Itchy eyes, runny nose, sore throat, headaches. It is a yearly ritual that Central Texans dread.
But cedar pollen does not just affect your sinuses. It affects your property too. That yellow-green film coating your car, your porch, your driveway, and the walls of your house is not just an annoyance. Left in place, cedar pollen can actually damage exterior surfaces and promote biological growth that creates bigger problems down the road.
What Cedar Pollen Does to Your Home
Cedar pollen is sticky. Unlike most tree pollen that washes away easily in the rain, cedar pollen has a tacky texture that makes it bond to surfaces. When it lands on your home's exterior, it adheres to the texture of brick, siding, concrete, and roofing material. Rain does not wash it off completely. Instead, the water partially dissolves the pollen and carries it into the pores of the surface, where it leaves a yellowish stain.
On lighter colored surfaces like concrete driveways, gray siding, or white trim, this staining is clearly visible. On darker surfaces, you may not see the staining as much, but the pollen creates another problem. It is organic material, and organic material is food for algae, mold, and mildew.
How Pollen Promotes Mold Growth
Cedar pollen acts as a nutrient base for biological growth. When pollen accumulates on surfaces that are also exposed to moisture, like the north side of your house, the underside of your eaves, or your patio on the shady side, it provides the food source that mold and algae need to get established.
In a typical year, Bell County gets enough moisture from January through March rain to keep exterior surfaces damp. The combination of deposited pollen and consistent moisture means that by the time spring arrives, many homes already have the beginnings of mold and algae colonies that will only get worse as the warmer, more humid months arrive.
A post-cedar-season pressure wash removes the pollen before it can serve as a mold incubator. This is one of the reasons we recommend an annual cleaning in late February or early March to Bell County homeowners. You are not just removing the pollen. You are preventing the cascade of biological growth that follows it.
Which Surfaces Are Most Affected
In our experience working across Temple, Killeen, and the surrounding area, these surfaces take the worst hit from cedar pollen:
- Concrete driveways and patios: The porous surface of concrete absorbs pollen and the staining it causes. The longer it sits, the deeper it penetrates.
- Brick and stone exteriors: The textured surface and mortar joints trap pollen in places where rain cannot reach. North-facing walls are the worst.
- Gutters and soffits: Pollen accumulates in gutters alongside leaves and debris, creating a thick sludge that holds moisture against the gutter material.
- Cedar fences: The irony of cedar pollen settling on cedar fences is not lost on anyone. The pollen promotes the same mold growth on fences that it does on house exteriors.
- Outdoor furniture and grills: Anything you left outside during cedar season is coated. A quick wash brings it back to usable condition.
- Roof shingles: Pollen settles between the granules on shingles and feeds the algae that causes those dark streaks. Homes that skip annual cleaning after cedar season develop roof staining faster.
The Best Time to Clean After Cedar Season
Cedar pollen counts typically peak in mid-January and taper off by late February or early March. The ideal time to schedule your post-cedar cleaning is late February through mid-March. This catches the tail end of the season and removes the bulk of accumulated pollen before the spring rains and warming temperatures kick biological growth into high gear.
If you wait until April or May, you are not just removing pollen anymore. You are dealing with established mold and algae growth that has been fed by months of pollen deposits and spring moisture. It is still cleanable, but it takes more treatment and more time.
What a Post-Cedar Cleaning Includes
Our standard post-cedar-season cleaning package includes:
- Full house wash (soft wash for siding and brick, paying extra attention to north-facing walls)
- Driveway and sidewalk pressure washing to remove pollen stains
- Patio and porch cleaning
- Gutter flush to remove pollen sludge and winter debris
- Rinse of outdoor furniture and fixtures
For most homes in the Temple-Killeen area, this takes a half day and gets your property back to looking clean for the spring and summer months. Many of our customers schedule this as an annual service, booking it in advance so they are first on our calendar when cedar season ends.
