Whether you’re just headed away for the weekend or leaving your plants behind for a week-plus trip, the interruption of your usual care and maintenance routine does present a risk to your indoor garden. In this article, we will discuss a few no-cost tricks you can use to ensure the health of your garden while you’re away, as well as recommend a few affordable products that make the task easier.
Why Adjust the Lighting on Herbs While Traveling?
Light is obviously an essential part of long-term plant health. It is the source of energy plants use to fuel their growth. Generally speaking, the more light your plants have access to, the faster they will grow. That’s usually a good thing, but more growth means they are also consuming more water.
If you’re traveling for an extended period, we recommend reducing your indoor herb garden’s exposure to light. This might mean moving it away from the window or reducing the number of hours per day by up to 75% or more. This reduction in light will not only keep your garden cooler (reducing evaporation) but also slow down its growth. That means the herb garden will consume water slower - which is particularly important if you’re not around to top it up!
To Keep Your Herbs Alive, They Need Moisture
Your indoor herbs, like your basil and cilantro plants, need water while you are gone to stay alive. Simply overwatering them once before you leave won’t work. You should water them, of course, but also set up a self-watering system and provide a way to conserve moisture and prevent evaporation. Here are a few low-cost ways you can preserve the moisture in your indoor garden while traveling.
Make A Plastic Bag “Greenhouse” For Smaller Herbs
Greenhouses don’t need to be fancy glass containers. A simple plastic shopping bag from the grocery store will work well enough. Up-end the bag over your pot and prop it up on skewers or chopsticks to keep it from touching the top leaves of your plant. Seal the bag closed with a large rubber band or string. If your herbs are too large to fit under a plastic bag, there are other things you can do to conserve moisture.
Create A Moisture Trap With A Pebble Tray
To create your moisture trap, you’ll need to:
- Create a moisture trap by putting tiny pebbles into a shallow tray (like a baking pan) and filling it with water so that the water just covers the rocks.
- Place your pots on top of this. The water will be able to travel up the drainage holes of the pot as needed when the potting soil gets too dry.
- Use small pebbles; water won’t travel easily from large rocks.
Create A Moisture Trap With Wet Towels Or Newspaper
If you’re short on trays and rocks, wet a towel and place it under your pots instead. Do this in a bathtub or sink so that the water doesn’t leak all over the floor. As an alternative, wet newspaper or paper towels and cover the soil. The newspaper will prevent evaporation as well as provide some moisture.
Set Up A Self-Watering System to Keep Your Herbs Alive
After setting up moisture conservation, set up this self-watering system:
- Fill a plastic jug with water and place it near your plants.
- Cut a length of cord or twine that will stretch easily from the jug to the pot. One end should be a few inches underwater and the other end should be resting in the pot. The cord/twine should be natural or porous so that water can travel through it.
- Use a small rock or heavy object to hold down the end of the twine in the pot.
- Place a strip of duct tape over the mouth of the jug so the water doesn’t evaporate and the other end of the twine doesn’t slip out.
- Water will travel through the cord/twine by cohesion, seeping from the jug down the cord into your pot. It’s a good idea to set this up a few days in advance to ensure it’s working before you leave.
Other Self-Watering Systems You Can Create to Keep Your Herbs Alive
If you don’t have the time or resources to create the above self-watering system, you can also try looking into an olla, plant watering spikes, or just use terracotta pots and plug the drainage holes with a cork, or you can also try out self-watering planters.
- Olla irrigation: Ollas are buried in soil and filled with water. Dry soil pulls the water through the porous unglazed pots, moistening the surrounding soil. They are perfect for keeping your herbs watered while you travel. For more details on olla irrigation, you can check out Wikipedia.
- Clay terracotta pots: You can also use normal clay terracotta pots. Plug the drainage hole, then fill it with water. The porosity of the material will slowly release water into the surrounding soil.
- Self-watering planters: Self-watering planters typically consist of a water reservoir at the bottom and a wicking system that draws water up into the soil as needed. This setup mimics natural processes, providing a consistent level of moisture and preventing both overwatering and underwatering.
Self-Watering Bottle Gardens
Another way to help your garden thrive while you’re away is to set up a simple Kratky-style hydroponic setup. The nice thing about hydroponics is that you create a way for the plants to water themselves (so you don’t have to!). The Urban Leaf Bottle Garden Kits are a good example of this. Essentially, the product sets up a way for plants to water themselves, so you don’t have to.
