How Often Should Commercial Planters Be Watered in Hot Weather?
While we’re nearing the end of summertime, it’s still plenty hot in much of the U.S., with many states still in a heatwave as daytime temperatures continue to soar. The lawn and landscaping around your commercial property may be brown or patchy in a few spots, and your in-ground plants may be a bit wilted from the summer heat.
But what about those commercial planters that have plants inside yet aren’t inside the actual ground? Do they require more water in hot weather, or should you taper back your watering? Continue reading to learn how often commercial planters should be watered in hot weather, and why choosing a quality commercial planter with add-ons like built-in irrigation systems offers many advantages and helps keep plants flourishing despite the heat.
How Often Should Commercial Planters Be Watered in the Heat?
How often are you currently watering your commercial plants? If you live in a southern state or the Midwest, you may need to water more often than other parts of the country. Watering plants in the heat can be challenging, especially if you’re caring for plants that are already tricky to care for. Watering too little can be just as damaging as overwatering, causing issues like yellowing, soggy soil, and wilting leaves.
So how often should you water your planters in this heat? That depends on the type of plant and planter you have. If you have drought-tolerant plants like ornamental grasses and succulents, they’re likely to survive in a heatwave, assuming you maintain your watering schedule. However, if you have plants that are sensitive to heat, like vegetables or pansies, you’ll need to pay careful attention to the soil and plant to determine how much water it needs.
Below are some great summer watering tips for commercial planters to help avoid overwatering and underwatering your planters:
Check the soil before you water
Know your plants’ requirements before you maintain a watering schedule
Change up your watering schedule for heatwaves and rainy days
Move your planter to a shaded area if needed
Caring for planters in the summer heat can be tricky, but having a high-quality planter with irrigation features matters, especially if your plants require frequent watering and moist soil.
Why Quality Commercial Planters Matter
Mass-produced planters from big-box retailers typically offer limited functionality when it comes to water management. Although many include standard drainage holes or removable knock-out plugs, these basic features do little to protect the plant’s roots or prevent overwatering. As a result, maintaining consistent moisture levels often becomes more challenging, particularly when watering planters in summer heat.
Proper drainage is one of the most important elements of successful container gardening, especially for commercial planters. Without an effective drainage system, excess water will collect at the base of the planter, creating saturated soil that can cause root rot and disease. In addition, poor drainage prevents excess fertilizer salts and dissolved minerals from flushing through the planter, potentially harming your plant’s roots. Traditional commercial planters—concrete planters, terracotta planters, or metal planters— don’t offer the engineered water movement needed to support long-term plant health, especially during the summer heat.
A custom commercial planter by PolyMade can be engineered with integrated drainage and irrigation solutions that create a healthier growing environment for your plants. Our sustainable planting system supports vigorous growth while reducing the maintenance demands of professional landscapes and takes the guesswork out of watering in the summer heat.
