When To Move Houseplants Outside

Your plants enjoy the warm temperatures and sunny days of summer just as much as you do! The Grow-HowTM Team provides all the information you need in regards to bringing your indoor plants outside throughout the summer.

Can all plants go outside?

Yes, during the hot summer months, all of our interior foliage plants can be moved outside. After all, there is where plants originated! They will appreciate breathing in the crisp outdoor air. When putting your plants outside, one of the most important things to consider is the strength of the outdoor sunshine.

Many typical houseplants thrive in bright, indirect light that is filtered by the canopy of taller trees above as they do in their natural habitat along the forest floor. You should avoid placing your plant in regions that receive direct sunlight if the plant you have indoors prefers indirect light. Additionally, it’s crucial to get your plant used to being outdoors.

How do I acclimate a plant to the outdoors?

The process of progressively acclimating your plant to a new environment, such as a change in temperature or light intensity, is known as acclimation. In order to avoid undue stress that can hinder growth or harm the plant, proper acclimation enables your plant to gradually adapt to its new environment.

Start acclimating your plant by putting it in a shaded place outside for an hour or two on the first day, and then gradually increase the amount of time it spends outside over the following seven to ten days. Most plants can tolerate direct sunlight during the morning hours since it is significantly less intense. About five days after you begin the acclimatization process, if your plant will receive morning sun, start putting it in the sun for brief periods of time each morning. It is better if plants with a preference for indirect light are protected from the sun by around 10 a.m.

Even plants that can tolerate direct sunshine, like a Bird of Paradise, Sansevieria, Ponytail Palm, and most cacti, need to be introduced gradually over the course of at least 10 days. This will prevent them from experiencing burnt leaves while they adjust to the strength of the full outdoor sun.

When do I know it’s safe to bring my plant outside?

When the outside temperature remains consistently above 50F, you can bring your plants outside without risk. Pay close attention to the forecast. Bring your plants inside for the night if the temperature is forecast to drop below 50F. When it becomes warmer, put them back outside.

They’ll probably be fine if you forget and expose them to lower temperatures for a brief time. Their growth may be temporarily stunted by temperatures below 50F, and leaf damage may result from temps as low as 35F. Most indoor plants will lose all of their leaves in freezing conditions, but if the exposure was only brief, the roots will usually survive.

Is it too soon for my plants to go outside?

Most indoor plants can be placed outside from May through September. Wait until two to four weeks after the last frost if you want to be safe because timing varies across the nation and from year to year. You could also decide to hold off a little longer if your garden is open to the elements.

Hardening off

Before removing your plants for the summer, gently acclimate them to the chilly temperatures and increasing light intensity outside. For the first one or two weeks, place the plants in a shaded area outside during the day and bring them inside at night.

Where to put them

When house plants are outdoors, they run the risk of scorching, so gradually increase their exposure to light. For shade and pest prevention, you can hang air plants, bromeliads, Christmas cactus, and orchids from a tree.

Summer care

House plants will need regular watering because they dry out quickly outside, so keep an eye on the compost. Watch out for pests like aphids, slugs, snails, and caterpillars as well. When watering, it’s also beneficial to provide a home plant fertilizer on a regular basis.

Returning indoors

Before the first frost, bring your houseplants back inside. Check them first for pests, such as slugs that may be hiding under the pot. Remove any damaged or burned foliage as well as any faded blossoms. Put your plants in a bowl of warm water if they are dry.

Can you transport plants outside in this weather?

When nighttime temperatures fall to 45 or 50 degrees Fahrenheit, experts advise bringing your plants inside. However, it could be wiser to take action much earlier, when the temperature inside and outside is roughly equal.

Can indoor plants endure the outdoors?

You reasoned that since plants originate outside, you should take your indoor plants outside. In any case, your house or apartment is somewhat cramped. They shouldn’t be harmed by it, right? To provide you the solution, we conducted some research.

Can indoor plants be placed outside? The sunlight and fresh air of the outdoors are rather enjoyable for indoor plants, but you can’t just grab your houseplant and transfer it outside at random one day. If not, it will experience shock and may pass away. It’s best to gradually acclimate the plant to its new environment.

Can you move indoor plants outside?

The key to successful gardening is to get your plants acclimated. If you are taking indoor plants outside, this is especially crucial. It isn’t a bad idea, though, for beginning plants that you’ve bought from a nursery.

Start off slowly while your plants adjust. When you’re ready to take indoor plants outside, gradually relocate them each day to a more sunny spot in your house. Take your starter plants outside and place them in the shade if you are currently keeping them in the most sunny area of the house. When you initially move your seedlings outside, position them behind a windbreak to prevent breaking when they harden because plants produced indoors won’t have been exposed to wind. Until your seedlings are sturdy enough to be planted, expose them to an additional hour or two of sunlight and breeze each day. If at any time throughout the acclimatization phase your seedlings begin to wilt, relocate them to a more shaded area or bring them back inside.

What degree of cold is too much for houseplants?

Planting too early might result in a crisis if a cold snap is impending, whether it was because you were seduced by some striking hue at the garden center or simply wanted to start the gardening season early. It’s not difficult to help your seedlings survive the great frost, but it does take some planning.

When temperatures drop, you can usually rely on improvised protection for plants. The necessary tools must be prepared in advance to protect plants from frigid mornings for larger plantings, such as a food garden.

Knowing when prized vegetation starts to turn frost-burned brown will help you know what to do when freeze warnings are in effect. As a general rule, plants typically freeze when the temperature stays at 28°F for five hours.

There are, of course, exceptions to this rule. When temps drop to 32–33F, seedlings often die because of their delicate new leaves. There are many low-temperature thresholds for tropical plants. Some collapse at temperatures below 40°F, while others break down at 35°F. Other plants are naturally resistant and can endure temperatures as low as 18 to 20 degrees Fahrenheit. Do a search in gardening books and internet resources to discover the threshold for your plants.

Take it up

Moving plants away from potential danger is the simplest cold-protection strategy. Potted plants and seedlings in flats both benefit from this. Moving plants onto a porch with a roof, into a garage or shed, or under a deck frequently provides sufficient shelter.

Rely on Water

Just before sunset, water the soil to raise the temperature of the surrounding air overnight as the water evaporates. Water-filled buckets or gallon jugs should be left in the sun all day. Move them close to threatened plants at night. Air temperatures will be moderated by the water, and if it freezes, heat will be released. To boost midday heating, paint a few water-holding containers black for best results.

the air flowing

The biggest harm is done to plants by cold, motionless air. To prevent frost from accumulating on plants, you can use an electric fan all night to create a breeze. Never forget to keep electrical connections dry.

Plants Should Be CoveredPlants should be covered with sheets, towels, blankets, cardboard, or a tarp to protect them from everything but the harshest freezing (28F for five hours). Inverting baskets, coolers, or any other container with a firm bottom over plants is also an option. Before it gets dark, cover plants to keep warm air in. Coverings shouldn’t ideally contact the foliage. If windy conditions are anticipated, anchor cloth coverings.

When the temperature rises and the frost has melted in the morning, remove coverings. Under dense covers, heat from the sun can accumulate and cause plant death.

Blankets that collapse

Row covers, or gardening blankets, should always be accessible. These covers are created in various thicknesses from plastic or synthetic fibers. Lay row covers directly on the plants, or suspend them over a bed with pegs to form a tunnel.

Activate lights

An incandescent light bulb produces enough heat to raise the temperature of the air around it just enough to keep a plant from freezing. For this method to operate, bulbs must be close to plants (within a distance of 2-3 feet). (Fluorescent bulbs can’t produce enough heat to complete this task.)

Defend specific plants

Set up hot caps

At planting time, stiff plastic containers with venting holes are placed over the individual seedlings. Hot caps function similarly to cloches (small greenhouses), but the daily task of applying and removing the covering is eliminated by venting holes. Use plastic two-liter bottles or gallon jugs with the bottoms cut off and the lids removed to simulate a hot cap (but saved). In the evenings when the weather turns chilly, replace the lids.

A Wall O’Water tepee, which encircles individual plants with a sleeve of water-filled tubes, is a variation on the hot cap concept. During the day, the water absorbs the heat of the sun. The water gently freezes at night, releasing the sun’s stored radiant heat and preventing the air within the tepee from becoming frosty.

How cold should it be for indoor plants?

The easiest time of year to kill a houseplant is definitely during the winter. Houseplants are put to the test by harsh growing conditions like low light levels, dry air, shorter days, and frigid temperatures.

Making care routine adjustments to accommodate seasonal growing circumstances is the key to ensuring that plants survive the winter. Review the fundamentals to provide your indoor plants with the best care during winter.

Winter causes the sun to set later in the day, which results in a 50% reduction in light levels near windows. During the winter, indoor plants that thrive near a sunny eastern or northern window during the summer may require a southern or western exposure. Similarly, plants near windows in the west or south that require filtered light in the summer might be able to endure direct sunlight in the winter.

To aid plants in adjusting to shifting light conditions:

  • If it’s possible, move plants nearer to the windows.
  • Window cleaning will maximize light transmission.
  • For the winter, move plants to new areas next to windows with more light.
  • Cleanse plants to allow leaves to utilize the light that is available to the fullest.
  • Add synthetic lighting. Fluorescent lights are sufficient. They generate less heat and are less expensive than conventional grow lights. For best results, place bulbs 4–12 inches away from plants.

Tropical plants, which make up the majority of indoor plants, like daytime temperatures of 65 to 75 F and nighttime temperatures of around 10 F lower. For many plants, temperatures below 50F can cause problems.

In order to make the thermostats more comfortable for you, keep in mind that your plants also require some thought.

  • Keep plants away from heat sources and cold gusts.
  • Maintain a few inches of space between plants and external windows.
  • Plants should be moved away from windows at nightfall in cold climates if windows freeze over at night. Additionally, you may tuck a thick shade or another insulating item between the plants and the glass.

In the cold, homes might only provide 5–10% relative humidity. Houseplants prefer 40–50%. Brown leaf tips and the presence of pests like Spider Mites are indicators that plants are being stressed by low humidity. Learn how to increase the humidity around plants in simple methods.

Overwatering is the most frequent issue that indoor plants encounter throughout the winter. 95% of indoor plants require the soil to almost totally dry out before watering. How do you determine whether plants need water?

  • Don’t only test a small area of the soil’s surface. When the root zone is dry, plants require moisture. Insert your finger up to two inches into the ground. Water the soil if it’s dry.
  • Pick up the pot. When soil gets dry, it becomes lighter. Lift pots right away after watering to feel the texture of the moist soil.
  • Plants won’t need water as frequently if winterized rooms are humidified. Water must be added to dry air.
  • The only exceptions to this rule are citrus and ferns in pots, both of which require continually moist soil. If you are uncertain, always do your research.

Never let plants sit in water that gathers in the drainage saucer overnight when you water.

Fertilize plants all winter long in mild climates. Winter fertilization of indoor plants is not recommended in the coldest climates with little natural light. When springtime outside plants begin to grow, fertilizer can be resumed.

In the spring and summer, when most indoor plants are actively growing, is the ideal time to repot them. Potted woody plants that entirely hibernate in the winter are the exception. Transplant those in the early spring before the buds break.

  • Numerous advantages of houseplants include bettering indoor air quality and lowering sickness rates.

When it’s 40 degrees outside, can plants be outside?

Many homeowners can’t wait for the weather to warm up because they know it’s time to move their indoor plants back outside into the sunshine. Some plants simply grow better outside. But at what temperature can a judgment be made without risk?

When is it safe to move indoor plants outside? 50 degrees at night must be maintained on a regular basis for a long period of time. When it remains within this range, you know it’s time to transfer your plants back outside.

Welcome to the club if you struggle to maintain indoor plants and don’t have a green thumb. You could assume you are safe if you have a week of warmer weather, but that isn’t the case. You must bring the plants back inside if the temperature suddenly starts to fall. We all know how unpredictable spring can be.

Keep an eye on the weather, especially the nighttime temperatures, and make sure that your furry pals are never outside when it is below 45 degrees. Anything below 40 degrees will seriously hurt tropical plants if you take good care of them.
