Pressure washing is an effective way to clean various surfaces around your home, from driveways to decks, to windows and fences. However, when performing pressure washing near plants or gardens, there is a significant risk of causing harm to the foliage. The high-pressure water can strip away soil, damage delicate plants, and even uproot them if not handled properly.
In this article, we will guide you through the steps you can take to ensure that your plants are protected while pressure washing your outdoor spaces.
Why Protecting Plants is Essential
Before diving into the details of how to protect plants, it’s important to understand why this step is necessary. Plants can be easily damaged by the high-pressure water from a power washer. Sensitive plants, such as flowers and shrubs, can lose their leaves or be uprooted if the water stream is too strong. Furthermore, the force of the water can erode the soil around the plants, destabilizing their roots. In addition to that, some detergents and chemicals used during pressure washing may harm the plants if not carefully managed.
For these reasons, it’s crucial to take proactive steps to prevent damage while still achieving the desired cleaning results.
Step 1: Choose the Right Pressure Setting
The first and most important step to protect your plants is to adjust the pressure setting on your pressure washer. Most pressure washers come with adjustable nozzles, allowing you to control the intensity of the water spray. For delicate areas around plants, it’s important to use a lower pressure setting.
Use a Wide Nozzle
The nozzle you select plays a significant role in the intensity of the water stream. A wide-angle nozzle is best for cleaning near plants because it disperses the water more gently. This reduces the risk of harming your plants and ensures that the water is not concentrated on one specific area. It’s always a good idea to test the pressure on a small area before moving on to cleaning around your plants.
Start with Low Pressure
If you’re unsure about the ideal pressure level, start with the lowest setting. You can gradually increase the pressure if necessary, but it’s better to err on the side of caution. Low pressure ensures that the water is less likely to harm the plants, while still providing a level of cleanliness to the surfaces you’re washing.
Step 2: Create Barriers for Protection
One of the most effective ways to prevent damage to your plants while pressure washing is to create barriers around the plants. This method helps shield them from the direct impact of water spray and reduces the risk of soil erosion.
Use a Plastic Sheet or Tarp
Placing a large plastic sheet or tarp around your plants can act as a protective shield. This simple technique keeps the pressure washer’s spray away from the plants and prevents water from washing away the soil. Lay the sheet flat on the ground, ensuring that the edges are securely positioned to avoid any water runoff.
Erect Temporary Fencing
Another option for protecting plants during pressure washing is to erect temporary fencing or barriers around them. This can be as simple as using garden stakes and a mesh screen to create a barrier that shields your plants from the direct spray. This method is especially helpful for taller plants and shrubs that may be harder to protect with a tarp alone.
Step 3: Keep the Nozzle at a Safe Distance
When pressure washing around plants, always maintain a safe distance between the nozzle and the plants. A close-range spray can harm the plant’s leaves, stems, and roots, even if you’re using a low pressure setting.
Maintain a Minimum Distance of 2-3 Feet
It’s essential to hold the nozzle at least 2-3 feet away from the plants to avoid damage. This distance helps diffuse the force of the water, reducing its potential to harm your plants. If you are pressure washing near smaller, more fragile plants, you may want to increase the distance to 4-5 feet to ensure they are well-protected.
Sweep the Wand Instead of Direct Pressure
Rather than holding the wand in one spot, always move the nozzle in a sweeping motion to spread the water evenly. Sweeping reduces the direct impact on the plants and helps minimize the risk of damage. It also ensures that no one spot receives too much pressure, which can cause plants to bruise, break, or even uproot.
Step 4: Water the Plants Before You Start
If you plan to pressure wash around plants or garden beds, it’s helpful to water the plants beforehand. This may seem counterintuitive, but moist soil is less likely to be washed away when pressure washing. By thoroughly watering your plants before cleaning the area, you can help stabilize the soil around them, making it less susceptible to erosion or displacement.
The Benefits of Pre-Watering
Pre-watering not only helps prevent soil erosion, but it also hydrates your plants. If you are pressure washing in the warmer months, the water helps maintain plant health, preventing them from becoming too stressed during the cleaning process. Be sure to water your plants about 30 minutes before starting the pressure washer, allowing the water to absorb into the soil.
Step 5: Avoid Chemical Cleaners Near Plants
While chemical cleaners can be effective for removing stains and grime, they may pose a risk to your plants. Many chemical cleaners contain harsh substances that can damage plant tissues, leaves, and soil. When pressure washing near plants, it’s best to avoid using any chemicals that could potentially harm them.
Opt for Eco-Friendly Detergents
If you must use a cleaner, always choose an eco-friendly option that is safe for plants. Look for biodegradable cleaners that do not contain toxic ingredients. These are less likely to cause harm to your plants or the surrounding environment. Always read the labels and make sure the cleaner you select is safe for use near plants.
Stick to Plain Water When Possible
In many cases, plain water is sufficient for most outdoor cleaning tasks, especially when using a pressure washer with the right nozzle and pressure setting. Using only water reduces the risk of exposing your plants to harmful chemicals and ensures a safer cleaning process. If you must use a detergent, apply it sparingly and only to the surfaces you intend to clean, keeping it away from your plants.
Step 6: Clean During Off-Peak Times
To minimize the stress on your plants during pressure washing, it’s a good idea to clean when the plants are less sensitive. Avoid pressure washing when your plants are in full bloom or during the heat of the day when they are more susceptible to stress. Early mornings or late afternoons, when the temperature is cooler, are the best times to clean your outdoor surfaces.
Avoid Cleaning During Extreme Heat
When temperatures are extremely high, plants can already be under stress from the heat. Pressure washing during these times may exacerbate the damage. Choose cooler times of the day to clean, and give your plants a chance to recover before pressure washing.
Step 7: Check for Damage and Care for Your Plants
After you have finished pressure washing, inspect your plants for any signs of damage. If you notice any broken branches, wilting leaves, or displaced soil, take immediate action to help your plants recover.
Reposition Displaced Soil
If the water stream has displaced soil around your plants, gently replace it and ensure the plant roots are stable. Water your plants again to help the soil settle back in place.
Prune Damaged Foliage
If you notice that any leaves or branches have been damaged during the pressure washing process, prune them carefully. This will help the plant recover more quickly and prevent any further stress.
Conclusion
Pressure washing can be a highly effective way to clean your outdoor surfaces, but when working near plants, it’s crucial to take the necessary precautions to protect your garden. By following the steps outlined in this article—such as adjusting the pressure setting, creating barriers, maintaining a safe distance, and using eco-friendly detergents—you can ensure that your plants remain safe while achieving a thorough clean. Always remember that the well-being of your plants should be your top priority when using a pressure washer near your garden or outdoor spaces.
