16 Jun Moving Your Houseplants Outside
Your plants have been staring out the window for six months. Now that winter is fading into memory, it is tempting to haul them all onto the patio and call it a day. But beware: a single afternoon of Illinois sun can scorch a leaf that has only known LED bulbs or filtered window light.
Think of this as a slow introduction rather than a sudden move. In addition to the intense natural light, you will also have to pay attention to the forecast and be aware of how much water your plants are getting. It is more work than a houseplant usually requires, but it can be very beneficial to your leafy friends.
Why Do Some People Bring Their Plants Outside?
Growth
This is typically the optimal environment for your houseplants, and when you can expect the most growth from them. This is a good time to add fertilizer to really see your plant's growth explode.
Strength
It may seem counterintuitive, but strong winds and rain help your plant develop a stronger trunk and base. Sitting in the elements is a bit of a resistance workout for it. All of that additional strength will significantly benefit the plant in the long term.
Pest Deterrent
If you have a plant struggling with common indoor pests, bringing it outside can help address those issues. Many of these insects live on indoor plants because they will not survive in the humidity of the summer.
With such great benefits, let's get down to brass tacks and explain how to do this the right way. To avoid plant shock, we recommend a one-week transition period.
- Days 1-2 Place plants in a fully shaded, protected spot. The north side of your house or a deep covered porch is perfect.
- Days 3-5 Introduce an hour of dappled morning sun. Avoid the 12:00 PM to 4:00 PM window when the heat is most intense.
- Day 7 Move them to their final summer home, ensuring they are grouped by light needs.
What Do I Need to Know?
Illinois summers are a mixed bag of heavy humidity and sudden thunderstorms.
- Humidity: Most tropicals like Ferns and Philodendrons will love our air-you-can-wear humidity levels. It mimics their natural rainforest habitat.
- Wind: You may be surprised to learn that wind dries out soil faster than heat does. Check your pots daily. If the pot feels light when you lift it, it needs a soak.
- Drainage: Ensure your outdoor pots have holes. A sudden Carol Stream downpour can turn a decorative cachepot into a drowning hazard in minutes.
Side note: Some houseplants are extremely sensitive to overwatering, so even with drainage holes, accidentally leaving them outside can be devastating. If you are vacationing plants like Sansevieria and succulents, we recommend bringing them under an overhang or even inside if they are in danger of a catastrophic overwatering.
Should Some Plants Stay Indoors?
While our high-humidity summers with occasional wind are perfect for many tropical houseplants, a few common favorites are better off staying on your bookshelf.
African Violets
These are the ultimate indoor divas. Their fuzzy leaves are highly sensitive to water spots and temperature swings. A single cold Illinois rain or overhead watering from a hose can cause permanent leaf rot or fungal issues.
Peace Lilies
Peace Lilies, or Spathiphyllum, are famous for being dramatic. Outside, they wilt almost instantly in heat over 80°F. Their thin leaves have zero protection against even filtered outdoor light, leading to immediate crisping.
Calatheas and Prayer Plants
These are forest floor specialists. Even the brightest shade outdoors is often too intense for them. They also require incredibly consistent moisture that the drying Illinois wind will strip away in hours.
Delicate Ferns
While Boston Ferns love a shady porch, Maidenhairs are too fragile. One gust of wind or ten minutes of direct afternoon sun will turn them into a handful of dried tinder.
How Should I Transition Plants Back Indoors?
Bringing your plant back inside can be surprisingly tricky, so whether you are wondering how to do it or when, we have you covered with the tips and tricks.
- When: We like to advise our neighbors and friends to bring them in when we start getting two to three consecutive nights below 55 degrees. If you wait until it gets colder, your plants may not survive, and bringing them in will give them a thermal shock similar to when you originally brought them outside. In the Carol Stream area, that is around the first week in October, but watch those September nights. It is better to be early and safe than late and sorry. Some shock is okay, and your plant can recover.
- Cleaning: This is also a great time to clean your plant, both the plant itself and the pot. After a few months outside, you will want to inspect closely for pests and keep plants away from your other houseplants if you see anything iffy.
- Repotting and Feeding: If your plant has gotten significantly bigger on its summer vacation, it might be time to put it in a bigger pot. That will give you an even closer look at the health of your plant than just a cleaning, as you can check for root issues while giving your plant a nice new home. This is the perfect time to give it one last feeding of fertilizer before your plant prepares for the winter.
Let the Plants Do Their Thing
Moving your indoor jungle outside is a rewarding way to see explosive growth in your plants, but it requires patience. By respecting the strength of the sun and the unpredictability of our local weather, you ensure your greenery stays vibrant until the first frost calls them back inside.
