When we plant our container gardens in the spring, it’s easy to get swept up in visions of overflowing blooms and patio perfection. What we don’t usually think about is what those lush planters will need in terms of care a few months down the road. By midsummer, those beauties are thriving, but without regular watering, they’ll wilt faster than your motivation in a heat wave. So, if you’re heading out on vacation — or just not thrilled about wrestling a hose under the blazing sun — you’ll need a solid plan. Mother Nature may grow the flowers, but let’s face it, she’s a lousy house sitter.
Here are several ingenious gardening hacks for hands-off watering that will keep your plant babies happy, even in your absence:
Group Plants Together in the Shade
If your containers are small enough to move around, grouping your outdoor pots together in a shady spot can do wonders for water conservation. According to the Kansas State Research and Extension Service, even sun lovers can tolerate shade for about a week or so, so putting them in the shade temporarily can buy you an extra day or two before they’ll need watering.
With all your plants in one spot, it’s also easier to set up a sprinkler on a timer to water them, or to MacGuyver another watering method of your choosing (more ideas below).
Groupings also help reduce transpiration and evaporation, which are affected by temperature, humidity and light levels. So, in the shade, they’ll be able to go more days without drinks.
Bathtub Method
Those of us with a plethora of high-maintenance indoor plants are probably familiar with the bathtub watering method: Simply place your plant containers into the bathtub, close the drain, and fill with an inch or two of water. As long as those pots have sufficient drainage holes — which, ahem, they should have already for the sake of healthy roots — they can wick water up into the soil as needed.
This method also works really well for smaller outdoor planters, as long as you can lift them without too much trouble. I’ve found that plant saucers or even old baking trays work well, as long as they have a tall rim to hold a few inches of water. If you have a lot of planters, you can even set them up in a kiddie pool, which costs less than $10 just about anywhere you can find one.
DIY Drip Systems
Creating your own drip system for planters is surprisingly simple. You’ve probably seen the fancy versions — like those blown-glass garden globes — but if looks aren’t your top priority, you can make your own for a fraction of the cost. (Plus, you get bonus points for recycling while you’re at it. Go ahead and give yourself a gold star.)
The simplest method uses a plastic bottle with a cap. Start by poking or drilling a few small holes near the top of the bottle. Fill it with water, screw the cap back on, and push the bottle upside down into the soil so the holes are buried. As the soil dries out, it will draw water from the bottle, keeping the moisture level steady. How long this method works depends on the size of the bottle and the number of holes you make. (If you have large planters, you might want to use more than one bottle to avoid uneven watering.)
If you want a more decorative look, you can use an empty wine bottle instead. In lieu of making holes, get a slow-drip watering spike to insert into the mouth (available at most garden centers or online).
DIY Wicking Systems
Similar to the bottle method, you can set up a DIY wicking system using items you probably already have at home. The materials may vary, but the concept stays the same: You need a container to hold water and a length of absorbent material to act as a wick.
Place one end of the wick — anything like cotton rope, twine, yarn or even strips of an old T-shirt — into the bottom of the water container. Bury the other end about 2 to 3 inches deep in your planter’s soil. The wick will draw water from the container and deliver it to the soil gradually, keeping it consistently moist. It’s a low-tech little miracle — thank you, osmosis!
This method also works well for multiple pots. Just run a separate wick to each one from a shared water source, and you’ve got yourself a low-maintenance hydration station.
Soaker Hoses
If you have a lot of large outdoor containers, it might be worth investing in a more permanent drip watering system. This can be as simple as running a few soaker hoses through your garden or as elaborate as a network of tubing, connectors and timers. Either way, the principle is the same: Water is delivered slowly and directly to the root zone through a soaker hose or perforated tubing, allowing it to seep into the soil at a steady, absorbable rate.
This method is both efficient and reliable — far less water is lost to runoff or evaporation, and the consistent moisture keeps your plants happy.
A basic drip irrigation setup typically costs around $50 to get started. Add a timer, and it’ll take care of watering whether you’re home or away. You can connect the system to a standard hose spigot — or better yet, hook it up to a rain barrel for an eco-friendly upgrade.
