5 Ways to Automatically Water Your Plants When You’re Gone

These DIY plant watering systems are a traveler’s best friend.

Sure, you can hope your neighbor or friend remembers to care for your houseplants during your next vacay. Or, you could forgo the favor and opt for one of our five self-watering ideas.

Tip: Before you pack your bags, do a test run. Otherwise, you risk vacation buzz kill when you get home.

Solution #1: Drip Water Irrigation System

This cheap solution only requires one plastic bottle for each houseplant. For potted trees, you may want to double-bottle to make sure water is dispensed evenly.

Tips: Make sure each planter is saturated with water before inserting the plastic bottle. Otherwise, the bottle will quickly empty.

If water flow is being blocked by compacted dirt, glue a tiny piece of screen to the bottle opening to prevent clogs.

Why we like:
Easy, quick fix
Trip length: 3 days
Set-up time: 5 minutes per plant

If you don’t like the look of upended water bottles, here’s an elegant alternative: aqua globes.

  • Globes are available in two sizes, so make sure the style you purchase is appropriate for your plant.
  • The planter needs to be saturated with water before you insert the globe.
  • To avoid the impacted dirt at the tip, embed the globe at an angle.

Solution #2: String Watering System

A wick-edly good idea that uses cotton or nylon string. But I learned that if you only have thin cord, braid it so it holds water better. I also learned that if you use a string that’s not 100% water absorbent, it’ll fail.

Just remember to use a container filled with water appropriate for your plant’s size.

Why we like: Easy, quick fix
Trip length: 3 days
Set-up time: 5 minutes per plant

Why we like: A designer solution for casual indoor gardeners with small plants.
Trip length: 3-7 days
Set up time: 5-10 minutes per plant

Tip: If you’re transplanting to the Grobal from a dirt planter, hold the exposed roots gently under running, room-temperature tap water. Once the dirt is washed away, cut off any dead roots and transplant into the hydroponic pot.
