Bring houseplants indoors for winter
As the temps start to cool and the leaves start to fall outside, we need to start bringing in your houseplants to create a plant oasis to enjoy all winter long.
Once the overnight temps are consistently dropping below 50°F, bring your houseplants indoors to avoid damage and stress to your plant. If you have flowering tropical plants, there is another method explained below that you can use to if you want to have them go dormant.
Watch our Youtube video &/or read instructions below.
Let the indoor greening begin!
Before they go inside…or at least before they’re near other plants.
Treat for pests. The outdoors is full of insects that also want to enjoy our plants. Before you bring them in, you can spray you plants lightly with a hose or inside shower to knock off any insects or dirt. Be careful to not blast them with high pressure as to not damage foliage. Next, you can spray with an organic insecticidal soap, Eight, or any insecticide spray safe for your houseplants if you notice pests.
You can also use a Bonide systemic houseplant insect control that you sprinkle onto the soil and watered in and will treat the plant up to two months against plant feeding insects. Ideally, you treat for pests at least a week before bringing in your plants to avoid introducing insects into your home or other houseplants.
Another method if you are worried about bug eggs in the soil is to repot your plants. You can knock off all the soil and rinse off all old dirt from plants and pot. Repot in new potting soil. This is an easy method if you need to put your plants in bigger pots or split any plants that have grown too large for your space.
See info below on houseplant insects.
You can prune back houseplants that had extensive growth if they don’t fit your space. When you prune, cut right after a leaf node, so you keep the node on. This is where new growth will start.
Check the plant toxicity if you have pets in the house that have a tendency to chew on things. Here is a great list of plants and their toxicity levels to make sure you aren’t bringing in a plant that may be harmful to your pets.
Imagine where you want to enjoy your plants and pay attention to their light needs! Get creative if you are finding that you don’t have enough shelf or floor space, if you need to keep the plant away from pets, or children. Try training your pothos to crawl up your wall with a pole or trellis or hang your ferns in your bathroom since they love humidity. Make sure that wherever you put them, you are paying attention to their light needs and avoid drafty areas.
It’s normal for your houseplants to have a transition period and some leaves may yellow and drop. Give them artificial sunlight with grow lamps if you find your plants are struggling due to lack of light.
Over-winter flowering tropicals:
Tropicals, like Bougainvillea, Hibiscus and Jasmine will need to go dormant in the winter if you don’t have a very bright spot to put it or it’s too large. Put them in a room that is between 40-50°F with a little sunlight and only water enough so the soil doesn’t get completely dry. No feeding of fertilizer needed until early spring. Flowering vines, like Jasmine, can be cut back 6-12″ above soil line. Tropical Hibiscus should be pruned after completely dormant. Prune a third of the way back, and make sure to keep two to three leaf nodes on the branch for new growth in the spring.
Lastly, have fun with creating your very own plant oasis! This is a year we need more than ever!
INSECTS YOU MAY SEE ON YOUR HOUSEPLANTS:
Please note: If you are worried about any spray treatments damaging a specific plant since some may be more sensitive than others, test the spray on one leaf first and look for signs of damage. Never spray in direct sunlight as that can result in sun scald marks due to the moisture on the leaves.
Signs of infestation: Plant looks covered with snow or leaves have some white spots.
Step 1: Try to wash the Mealybugs off with a steady stream of water. When they have developed their hard outer shell, this may be difficult. Dip cotton balls in alcohol and remove all visible mealybugs. Use cotton balls to clean the leaves and cotton swabs to clean inside small gaps.
Step 2: Repeat the treatment as necessary. This is best for light infestations. Mix 1 cup of rubbing alcohol with 1 quart (32oz) of water. Pour the solution in the spray bottle or straight rubbing alcohol for thicker, hardier leaves.
Step 3: Spray the whole plant, not only where mealybugs are visible. Spray leaves well on their tops, under leaves and stems. Repeat the treatment once or twice a week until the issue is gone.
Alternative sprays for heavy infestation that may work better: Insecticidal Soap Spray, Neem oil or pyrethrins are other sprays that can be used if alcohol wipe isn’t working and often times a quicker way to kill pests.
Signs of infestation: Plant leaf gets a “dusty” look in an area. They can be yellow or red in color. Often found on the underside of leaves. Spider mites are seen more often in the winter inside because they prefer dry and warm environments. Raised humidity, keeping away from heat source or locating plants in higher humidity areas helps in prevention but not guaranteed.
Step 1: First dislodge mites with a steady stream of water outside or in the shower. Dip cotton balls and swabs in alcohol and remove all visible mealybugs. Use balls to clean the leaves and swabs to clean inside the gaps.
Step 2: Mix 1 cup of rubbing alcohol with 1 quart (32oz) of water. Pour the solution in the spray bottle.
Step 3: Spray the leaves wipe off or use a houseplant insecticidal spray. Some people use Neem Oil that can help but an insecticidal spray works the best and will take less time to get rid of them.
Step 4: Treat any plants that are nearby as well since they spread easily or at least rinse off their leaves and spray with alcohol. *For any spray you can test a leaf to make sure it doesn’t damage the leaf and avoid spraying the leaf during the sunniest part of day or if the plant gets direct light.
Step 5: Repeat the treatment once or twice a week until the issue is gone.
Signs of infestation: Tiny small black bugs are flying around the soil of your plants. They do not feed on your plants but take advantage of moist soil to lay their eggs within the first couple inches of soil.
Step 1: Change your method of watering. Water your plants by setting them in water and they will take up water from below. Leave the top 2 inches of soil dry. Alternatively, only watering your plants once the soil is dry a couple inches down and try to prolong between watering until reduced signs of adult gnats are seen.
Step 2: Use BT- bacillus thuringiensis powder. It’s a natural bacteria that produces proteins that kill insects. Sprinkle BT on the top of soil of your plants. It is safe to use around humans and mammals but avoid ingestion of any product.
Step 3: Control flying adult population with sticky traps placed around your plants.
If you see signs of any other insects on your leaves, most insects can be controlled with above methods of wiping leaves off, use insecticidal spray and systemic insecticide.
If you have any questions about identifying an insect, please email us a picture of your plant if there are signs of insect damage to firstname.lastname@example.org.
