Will A House Wash Kill My Plants

Will A House Wash Kill My Plants

The allure of a pristine, well-maintained home is undeniable. A sparkling clean exterior can significantly enhance your property's overall appearance. However, the concern that pressure washing or house washing might harm your precious plants often lingers in the back of homeowners' minds. In this extensive guide, we delve into the topic of house washing and its potential impact on your plants. The good news is that pressure washing won't necessarily harm your plants if you take certain precautions. We'll explore these precautions in depth, ensuring that your house can shine without putting your greenery at risk.

Watering Your Plants

One of the simplest and most effective precautions you can take before pressure washing is to water your plants. Doing so dilutes the runoff from bleach or detergent used during the process. This is particularly important when bleach is involved, as it prevents the runoff from turning into salt, which could inhibit your plants' ability to absorb water. Moreover, it's critical to rinse your plants after the pressure washing process to remove any excess chemicals that may linger.

Covering Your Plants

Covering your plants is another useful technique to protect them during house washing. Using a plastic sheet is a straightforward approach. However, there is a caveat. Extended periods of covering can restrict the air supply to your plants, potentially leading to their demise. To avoid this, consider covering only the specific area being pressure washed. After completing one section, promptly remove the covering and reposition it to shield the next set of plants. This strategy ensures that your plants won't remain covered for an extended period.

Using Detergent Instead of Bleach

Opting for a detergent-based pressure wash can be a more environmentally-friendly choice when compared to bleach. Detergent is typically diluted to a 10:1 water-to-detergent ratio, making it less harsh on plants. However, it's essential to exercise caution when using detergent, as it can still pose challenges.

Detergent has the potential to leave brown spots on plants, which can be unsightly and, in some cases, harmful. To mitigate this, follow these steps:

1. Water Your Plants Before Pressure Washing: This step helps prepare your plants and minimize the impact of any detergent runoff. Well-hydrated plants are better equipped to handle the cleaning process.

2. Rinse Your Plants Afterwards: After the pressure washing is complete, thoroughly rinse your plants to remove any lingering detergent residue. This ensures your plants remain healthy and free from unsightly brown spots.

3. Use Diluted Detergent: Ensure that the detergent is properly diluted according to the manufacturer's instructions. Using a detergent that is too concentrated can increase the risk of plant damage.

By following these guidelines, you can harness the power of detergent-based pressure washing while safeguarding the health of your plants.

Adjusting Pressure

One of the most critical factors in ensuring the safety of your plants during house washing is adjusting the pressure. High-pressure jets can potentially harm your plants by damaging their leaves, stems, or roots. It's crucial to employ the right pressure levels to balance the cleaning efficiency and plant protection.

Reputable professionals will carefully assess your property and make necessary adjustments to protect your plants. They'll consider factors such as plant type, age, and location to ensure that the cleaning process won't negatively impact your landscaping.

Eco-Friendly Solutions

Many modern house washing services employ eco-friendly cleaning solutions. These environmentally-conscious products are formulated to be safe for both your home's exterior and the surrounding plants. By choosing a service that uses eco-friendly solutions, you can rest assured that your plants won't suffer any adverse effects. Additionally, the runoff from these eco-friendly solutions won't pollute the soil or harm aquatic life in your area.

Professional Expertise

Hiring professional house washing services provides the benefit of their expertise. Experienced professionals understand the delicate balance required to protect your home and landscaping. They'll assess your property, tailor their approach to your specific needs, and make any necessary adjustments to ensure that your plants remain unharmed.

Timing Matters

The timing of your house washing can significantly impact your plants' well-being. Generally, spring and fall are the best seasons for this type of maintenance. During these times, most plants are either dormant or haven't yet started to bloom, reducing the risk of harm during the cleaning process. Timing your house washing in harmony with your plant's growth cycle can make a significant difference.

Regular Pruning

Keeping your plants well-pruned and maintained can also help safeguard them during house washing. Pruning promotes healthy growth and removes any parts of the plant that might be in the way or at risk of damage during the cleaning process.

Treating Plant-Specific Concerns

Different plants have unique requirements and sensitivities. Some plant types, such as ferns and succulents, are more sensitive to chemicals and pressure than others. If you have unique or sensitive plants on your property, it's essential to discuss your concerns with the house washing service. They can tailor their approach to address any specific plant sensitivities, ensuring the safety of your unique greenery.

Assessing the Aftermath

After your house washing is complete, it's essential to assess your plants. Check for any signs of distress, such as wilting leaves, discoloration, or unusual growth patterns. While professional house washing is generally safe for your plants, keeping a close eye on your landscaping allows you to address any concerns promptly.


The myth that house washing kills plants is just that—a myth. With the right precautions, timing, and professional expertise, you can maintain your home's exterior while keeping your beloved plants safe and thriving. House washing can enhance the beauty of your home and its surroundings.
