Summer Lovin': Keep Your Houseplants Thriving All Season!

House plants
The season brings longer days, warmer temperatures, and plenty of sunshine, all of which are great for houseplants. However, it's important to remember that summer can also be a challenging time for indoor plants. In this article, I'll be sharing my top tips for keeping your houseplants healthy and happy throughout the summer months.


Introduction to Summer Houseplant Care

Summer is a time of growth and renewal for many plants, and your houseplants are no exception. With the right care, they can thrive and bring life and color to your home. However, it's important to understand that summer presents its own unique challenges for indoor plants.

One of the biggest challenges of summer is the heat. Many houseplants are native to cooler, more temperate climates, and can struggle in hot, dry conditions. Additionally, the increased humidity that often accompanies summer can create the perfect environment for pests such as spider mites and mealybugs.

Despite these challenges, with a little bit of extra care and attention, your houseplants can flourish throughout the summer months.

The Impact of Summer on Houseplants

As mentioned earlier, summer can be a challenging time for indoor plants. Here are some of the ways that the season can impact your houseplants:

Heat and Drought

During the summer months, temperatures can soar, and the air can become dry and arid. This can be particularly challenging for houseplants, many of which are adapted to more temperate climates. When temperatures rise above 85°F, many plants can begin to experience heat stress, which can cause leaf drop, wilting, and even death.


While some plants thrive in high humidity, others can struggle when humidity levels rise above 60%. High humidity can create the perfect conditions for pests such as spider mites, mealybugs, and scale insects to thrive.


Summer brings longer days and more intense sunlight, which can be a bonus for many houseplants. However, it's important to remember that not all plants thrive in direct sunlight. Some plants, such as ferns and peace lilies, prefer bright, indirect light, while others, such as succulents and cacti, can handle full sun.

Tips for Watering Your Houseplants in the Summer

Watering your houseplants is one of the most important aspects of summer care. Here are some tips to ensure that your plants stay well hydrated:

Pay Attention to the Soil

During the summer months, it's important to monitor your plant's soil regularly. As temperatures rise, plants may need more frequent watering to prevent the soil from drying out completely. Check the soil moisture level by sticking your finger about an inch into the soil. If it feels dry, it's time to water.

Water Deeply and Infrequently

When you do water your plants, make sure to water deeply and thoroughly. This will help encourage strong root growth and prevent the soil from becoming waterlogged. A good rule of thumb is to water until water drains out of the bottom of the pot.

Consider Using a Moisture Meter

If you're not sure when to water your plants, consider investing in a moisture meter. These handy devices measure the moisture level in the soil and can help take the guesswork out of watering.

The Importance of Light for Houseplants in Summer

As mentioned earlier, summer brings longer days and more intense sunlight, which can be great for many houseplants. However, it's important to remember that not all plants thrive in direct sunlight. Here are some tips for ensuring that your plants get the right amount of light:

Know Your Plant's Requirements

Before you place your plant in a new location, make sure you know its light requirements. Some plants, such as snake plants and ZZ plants, can handle low light conditions, while others, such as fiddle leaf figs and bird of paradise, require bright, indirect light.

Rotate Your Plants

If your plant is only getting light from one direction, it can begin to grow lopsided. To ensure that your plant grows evenly, rotate it every week or two.

Consider Using Shade Cloth

If you have plants that require bright, indirect light, but your home gets a lot of direct sunlight, consider using shade cloth. This material can be placed over windows or skylights to filter out some of the intense sunlight.

Humidity and Temperature Control for Summer Houseplants

As mentioned earlier, high humidity can create the perfect conditions for pests such as spider mites and mealybugs to thrive. Here are some tips for controlling humidity and temperature:

Use a Humidifier

If your home is particularly dry, consider using a humidifier to increase humidity levels. This can be particularly beneficial for plants that require high humidity, such as ferns and orchids.

Group Your Plants Together

Another way to increase humidity levels is to group your plants together. As plants transpire, they release moisture into the air, which can help create a microclimate of higher humidity.

Keep Your Plants Away from Drafts

During the summer months, it's important to keep your plants away from drafts from air conditioning units or open windows. Sudden changes in temperature can stress your plants and make them more susceptible to pests and disease.

Fertilizing Your Houseplants During Summer

During the summer months, your plants are growing rapidly, and may require more nutrients than they do during the rest of the year. Here are some tips for fertilizing your houseplants in the summer:

Use a Balanced Fertilizer

During the summer months, it's best to use a balanced fertilizer, with equal amounts of nitrogen, phosphorus, and potassium. This will help encourage healthy growth and flowering.

Don't Over-Fertilize

While it can be tempting to give your plants extra fertilizer, it's important not to overdo it. Too much fertilizer can burn your plant's roots and cause damage.

Follow the Manufacturer's Instructions

When fertilizing your plants, be sure to follow the manufacturer's instructions carefully. Different fertilizers have different application rates, and it's important to use the correct amount to avoid over-fertilization.

Repotting and Pruning During Summer

Summer is a great time to repot and prune your houseplants. Here are some tips for doing so:


If your plant has outgrown its current pot, or if the soil is compacted and not draining well, it may be time to repot. Choose a pot that is one size larger than the current pot, and use fresh, well-draining soil.


Summer is a great time to prune your plants, as they are actively growing and can quickly recover from pruning. Remove any dead or yellowing leaves, as well as any stems that are crossing or rubbing against each other.


If you have a plant that you'd like to propagate, summer is a great time to do so. Many plants, such as pothos and spider plants, can be propagated easily from stem cuttings.

Preparing Your Houseplants for the Fall and Winter

As summer comes to a close, it's important to start preparing your houseplants for the cooler months ahead. Here are some tips for doing so:

Reduce Watering

As temperatures begin to drop, your plants will require less water. Reduce watering frequency and allow the soil to dry out slightly before watering.

Move Your Plants Indoors

As temperatures drop, it's important to move your plants indoors to protect them from the cold. Choose a bright, sunny location, and be sure to avoid placing your plants near drafts or heating vents.

Consider Using Grow Lights

As the days get shorter, your plants may not be getting enough light. Consider using grow lights to supplement natural light and keep your plants healthy throughout the fall and winter.


Summer can be a challenging time for indoor plants, but with the right care and attention, your houseplants can thrive and bring life and color to your home all season long. By paying attention to your plant's needs for water, light, humidity, and nutrients, and taking steps to control pests and disease, you can help your plants grow and flourish throughout the summer months and beyond.

So, go ahead and enjoy your summer with your lovely indoor plants and make your home a beautiful and lively place!
