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.
What temperature is safe for bringing indoor plants outside?
To be safe, don’t even think about putting indoor plants outside until one month following the last frost. Some advice claims that once the evening temperature is constantly above 55 degrees F, your plants will be fine.
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 indoor plants be placed outside?
One of the most important elements causing plant shock is light. In actuality, outdoor sunshine is much more intense than indoor sunlight. Even while most houseplants need enough light, they can be difficult to transition from one extreme to another without the right preparation.
You shouldn’t put any indoor plants in direct sunlight outside in order to ensure a successful transfer and minimal plant stress. Instead, find a spot that is nicely covered, such as your patio or a tree, and let your plants enjoy some fresh air there for a few hours every day. Then gradually relocate them to a location with some sunlight, increase the amount of time they spend outside, and eventually leave them outside all day. The houseplants should be fully accustomed to their outside surroundings after a few weeks and can stay there all summer.
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 chilly is 40 degrees for indoor plants?
A house plant could potentially be in danger at any temperature below 50 degrees. Your plant won’t be able to grow if the temperature drops too low. It will eventually perish from the cold. The majority of indoor plants, though there are few exceptions, like conditions that are between 65 and 75 degrees during the day. They typically prefer temperatures between 55 and 65 degrees at night.
Low temperatures can be tolerated by the majority of tropical houseplants, but they won’t grow. In general, indoor plants can’t tolerate temperatures below 50 degrees.
Can Houseplants Survive 40 Degree Temperatures?
40 degrees is too cold for the majority of indoor plants. This is particularly true when the temperature lowers to 40 degrees from a warm one. One of the most frequent reasons for plant death is sudden temperature drops.
Your plant won’t be able to endure cold temperatures indoors, even if it can do so outdoors. A plant is unlikely to be able to tolerate the cold if it becomes accustomed to the conditions inside.
You should cover your plants if your house will be at 40 degrees for an extended amount of time. However, if you believe the chilly weather would just stay one night, you don’t need to cover.
If you choose to cover your plants, be sure to choose the right covering. Only cover plants that are in direct sunlight with black plastic. Clear plastic shouldn’t be used to protect plants from the sun since it gets too hot.
Are indoor plants too cold for 52 degrees?
It is important to keep an eye on temperatures above 45 degrees Fahrenheit. Before overnight lows fall below 45 degrees, any indoor plants that are spending the summer outdoors must be brought inside.
Is 40 degrees too chilly for plants to be left outside?
WBRC – BIRMINGHAM, Alabama Some of you may have already set your indoor houseplants outside, while others, like myself, haven’t done so.
After doing some research, I learned that houseplants need to be brought indoors as soon as the overnight low drops below 45 degrees. Temperatures below 40 degrees are harmful to the majority of tropical plants. Well, Thursday’s low 40s and Friday’s mid 40s are predicted as our temperatures. If we see a couple people in their upper 30s on Friday morning, I won’t be surprised.
If you place your indoor plants outside, you may wish to bring them inside or, like me, wait until May before thinking about doing so. While some are light, I have some large, heavy potted plants that I only want to move outside once until the late fall.
Most hanging or potted plants, such petunias, are safe as long as the temperature is above 39 degrees, and especially if it stays over the freezing point. I don’t anticipate any freezing temperatures over the next two weeks, but by Friday morning, some places north of I-20 may experience temps in the upper 30s. The majority of hardy annuals will be fine, so placing tropical plants outside would worry me more. For instance, peace lilies cannot endure chilly drafts or temperatures below 45 degrees.
Additionally, I would wait before planting tomato or pepper plants because they do not like temperatures below 55 degrees, or in some cases 50 degrees.
The average low temperature is 52 degrees, but during the next several weeks, we will occasionally dip below average, so I wouldn’t plant some crops, seeds, or delicate houseplants until May. Given that Boston Ferns can withstand sporadic blasts of cold air between 40 and 50 degrees, I did set them outside.
You can just Google it if you have any questions about your plants and if temperatures are too chilly for them.
Ponytail Palms (Beaucarnea recurvata)
Ponytail palms can be cultivated outdoors in either oblique or direct sunlight, and they prefer for their soil to become completely dry in between waterings. This plant should be moved outside gradually because being exposed to direct heat from indoors will shock it. This plant will adore soaking up the summer sun once it is outside.

Does rain benefit houseplants?
Why not let your plants outside in the rain since all plants need to be watered? You might think it’s a fantastic idea, especially since your plants could use a good watering. Your houseplants, however, are used to being loved and safeguarded, but the outside climate might be harsh. So, should you leave indoor plants outside in the rain?
Yes! Your indoor plants should occasionally be exposed to rain. Rainwater’s higher oxygen concentration can even prevent your indoor plants from drowning. But be ready for potentially windy conditions, low temperatures, and sudden downpours.
Although the rain might be quite useful, if you’re not careful, it can also harm your indoor plants. Once you’ve finished reading, you’ll understand how much is too much and when to bring your indoor plants back inside.
Why does rainwater benefit plants more than tap water?
To collect water and water my indoor plants, I catch it in buckets on my deck. I’ve been doing this for a while, and my houseplants have done great. Could you explain why rainfall is preferable to tap water for plants?
In general, rainwater is far purer than tap, city, or well water. Few salts, minerals, treatment chemicals, or medications, which are frequently found in municipal tap water, are present in rain.
Even though it is generally pure, raindrops may contain airborne particles like pollen or dust. For those of us who grew up during the Cold War, being warned not to consume snow or rain due to the radioactive fallout from above-ground nuclear testing was common knowledge.
Because it contains minerals from the bedrock it originates from, well water can be exceedingly hard. My well water is quite sulfurous and hard. On my plates and in the soil of my indoor plants, it leaves a white residue. My toilet gets rust spots from my water.
When you water your indoor plants with tap water, whether it comes from a municipal or well, salts and pollutants may accumulate in the soil. Softened water shouldn’t be used to water your plants because it contains too much sodium for them. The roots cannot absorb water if the soil is too salty. This may eventually harm the soil and roots of your indoor plants.
Most plants can use tap water that hasn’t been softened. Municipal water that has been fluoridated, however, may result in a buildup of fluoride in the soil, which may eventually damage indoor plants, particularly those with long, narrow leaves, like the spider plant. To allow the fluoride and chlorine gas to evaporate before watering plants, it is helpful to leave chlorinated and/or fluoridated water out overnight at room temperature in an open pitcher.
