Summer Watering Tips for Large Outdoor Planters: Why Drainage & Irrigation Integration Features Matter

How are your plants doing in this heat? Hopefully, your plants are flourishing and thriving this summer, producing blooms and vibrant flowers for your employees, guests, and the public to admire. Though summer blooms can be stunning additions to any commercial property, caring for plants during the hot, humid months can be challenging, especially if you have plants that aren’t native to your state.

Whether you have a restaurant, retail center, hotel, hospital, or other commercial space, you likely have large outdoor planters placed around your property, whether potted plants that add privacy or separate areas into zones. Keeping your plants well hydrated during the summer months can be tricky, but it doesn’t have to be. Continue reading to learn summer watering tips for large outdoor planters and to understand why drainage and irrigation integration features matter.

Summer Watering Tips for Large Outdoor Planters

Caring for plants in large outdoor planters can pose challenges, including overwatering and underwatering during the summer months. Because certain conditions like wilting and discolored leaves can mimic other issues—overwatering, underwatering, disease—determining the cause of your plant’s condition can be tough. 

Below are some summer watering tips for large outdoor plants to ensure you’re caring properly for your plant this summer:

Check the Soil Before You Water

One of the most common mistakes when caring for plants inside planters is overwatering. Many plants are on a watering schedule to ensure they receive adequate water each day in the summertime. However, setting a calendar reminder or scheduling a self-watering system on a consistent schedule can be dangerous for your plants, causing damage such as rot, oxygen deprivation, pest infestations, and wilting leaves. Before you adhere to that watering schedule, check the soil. Make sure your plant’s soil has dried out between waterings and that it isn’t overwatered or too dry. Checking the soil before watering will help prevent overwatering and underwatering, helping your plant flourish and bloom.

Know Your Plants’ Requirements

Caring for plants isn’t a one-size-fits-all approach; every plant has different needs that require varying watering, fertilization, and moisture. Keeping your plants healthy during the summer months starts with knowing each plant’s requirements, including how much water it needs, when and how often to fertilize, whether it prefers more sun or shade, and other needs. So, before you bust out the hose, research your plant to ensure you’re not underwatering or overwatering.

Change Your Watering Schedule

Have you noticed your plant’s leaves are starting to wilt in the early afternoon hours? Do the leaves seem a bit crispy in the morning? Whatever the case, changing your watering schedule can help your plant get maximum hydration without having the soil get too dry between waterings. For example, let’s say you’ve been noticing your begonias are wilting each afternoon. Adjust your watering schedule to ensure the begonias get enough moisture at the start of each day to ensure they aren’t wilting in the afternoon heat.

Move Your Planter to a Shaded Area

How much direct sunlight does your plant need? If it only prefers a few hours each day, yet your planter is located at an unshaded entrance of your restaurant, it likely needs to be moved to a shaded area. Likewise, if your hydrangeas are placed in direct sunlight for most of the afternoon, they should be relocated to a shaded area, as they prefer protection from afternoon sunlight. Moving your planter to a shaded area, especially during the summer months, can make all the difference for your plant.

However, moving a standard large planter isn’t easy. Concrete planters can weigh over 1,000 lbs, so relocating them is nearly impossible without renting expensive equipment. Choosing a planter that can be moved seasonally will protect your plant, ensuring it isn’t exposed to too little or too much sunlight. 

Why Drainage & Irrigation Features Matter

Standard big-box store planters offer very few options for drainage and irrigation features. While some big-box store planters offer some drainage options, they’re often basic, pre-drilled drainage or knock-out plugs that allow water to escape. However, these planting containers are basic, offering little assistance for keeping the plant’s soil moist or allowing it to dry out between waterings.

Drainage features matter for many reasons. For one, without proper drainage, your planter will allow water to pool at the bottom, putting your plants at risk of developing root rot and suffocating. Next, without adequate drainage features, fertilizers and minerals can accumulate near the bottom of the planter, preventing them from flushing out. While some big-box stores have drainage holes, they don’t protect plant roots or adequately flush out minerals.

Having irrigation features in commercial planters matters because they can prevent your plants from drying out too quickly between waterings, especially important during the drier summer months. Irrigation features—self-watering reservoirs or drip systems—create more consistent moisture for your planters, keeping the soil moist while preventing it from becoming soaked or drying out. Not only do irrigation features keep the soil moist, but they also prevent accidental underwatering and overwatering, keeping your plants healthier.

While drainage and irrigation features matter in planters, these options aren’t available from planters found at big-box or home improvement stores. These often have basic features that don’t support a stable environment for plants to thrive. However, building a custom PolyMade planter that has drainage and irrigation features will consistently maintain an ideal environment for your plants, helping them flourish.
