Top Indoor Gardening Tips

Even if you don’t have an outdoor space, you can still cultivate a green thumb. Indoor gardening lets you grow beautiful plants all year round, right inside your home. However, it’s not always as straightforward as just popping a plant in a pot.

If you want to ensure your indoor garden flourishes, you’ve come to the right place. Our top indoor gardening tips will guide you through everything from watering and lighting to pest control. You’ll learn how to select the right plants, when and how to prune, and even how to propagate your own plants.

Let’s embark on your indoor gardening journey together.

Choose the right containers

In choosing containers for your indoor garden, consider the depth and size that will provide enough room for your plants’ roots to grow. Different plants have different root systems and require varying amounts of space to grow and flourish. For instance, ‘greens’ like spinach, lettuce, and kale need at least 5 inches of soil depth. If you’re growing peas, beans, cucumbers, peppers, or other small bush or vine plants, they’ll need a soil depth of at least 7 inches.

Root crops such as beets, carrots, turnips, and potatoes, however, need more room to develop. For these, choose a container that allows for a soil depth of 12 inches. It’s important to remember that providing ample root space isn’t just about the plant’s current size. You’re planning for the size it will become.

In addition to the depth, pay attention to the width of the container. Your plants shouldn’t feel cramped. They need room to breathe and grow. If a plant becomes root-bound, its growth may be stunted, and it could become stressed.

Also, consider the material of the container. Plastic pots are lightweight and retain moisture well, but clay or terracotta pots provide better aeration. Ensure your containers have good drainage to prevent waterlogging.

Lastly, remember to clean and disinfect your containers before use, especially if they’ve been used previously. This will help to prevent the spread of diseases. By carefully considering your container selection, you can create a healthy and productive indoor garden.

Get the soil right

While you might be tempted to simply fill your pots with dirt from your backyard, it’s crucial that you choose a sterile, commercial potting mix for your indoor garden to prevent introducing pests and diseases. Ordinary soil may seem like a convenient and cost-effective option, but it often compacts over time, making it difficult for your plants’ roots to breathe and grow.

In contrast, a high-quality potting mix provides a lightweight, airy environment that allows roots to spread out and absorb nutrients effectively. This type of soil also retains just the right amount of water – not so much that it drowns the roots, but enough to keep your plants properly hydrated.

Here’s a quick guide to help you get the soil right:

  1. Choose the Right Mix: Opt for a commercial potting mix that’s sterile and free from pests and diseases. Some mixes are specially formulated for indoor plants, so check the label when making your selection.
  2. Check for Drainage: Good soil should drain well to prevent waterlogging. Look for a mix that includes vermiculite or perlite, both of which improve drainage.
  3. Consider Nutrient Content: Some potting mixes come pre-fertilized. These can give your indoor plants a great start, but remember to follow the manufacturer’s instructions to avoid over-fertilizing.
  4. Regularly Refresh the Soil: Over time, potting soil can become depleted of nutrients. Make it a habit to replace the top layer of soil in your pots every few months to keep your indoor garden thriving.

Pick your plants based on available space

You need to carefully consider the amount of space you have available before deciding which plants to grow in your indoor garden. Not every plant is suitable for indoor gardening due to space constraints. For instance, corn, okra, and indeterminate tomatoes can reach up to 10 feet in height, making them impractical for most indoor settings.

Instead, opt for plants that have been specifically bred for compact growth. Dwarf varieties of peppers and other vegetables are a great choice, as are determinate tomatoes, which are bush-type plants that are more contained in size. Herbs, too, are excellent for indoor gardens, as most varieties stay relatively small and are easy to manage. Consider low-growing fruits such as strawberries and figs, which can thrive under indoor conditions without taking up too much space.

However, don’t just consider the plant’s height. Think about its spread as well–how wide it will grow. Some plants, while not tall, spread outwards and can still take up a considerable amount of room.

Vertical gardening can also be a smart way to maximize your available space. Many plants, including certain varieties of tomatoes, beans, and even cucumbers, can be trained to grow upwards on a trellis or stake. This allows you to make the most of your vertical space, letting you grow more in less room.

Get the light right

Getting the light right is crucial when cultivating your indoor garden, as different plants require varying amounts of sunlight. Many fruits and vegetables, for example, need at least six hours of direct sunlight daily. This makes a south-facing window an optimal location for your indoor garden. But don’t worry if you don’t have one, you can still ensure your plants get the light they need.

Here are four tips to help you get the light right:

  1. Use a Strong Light Source: If sunlight is limited, supplement with a strong source of light. The VIPARSPECTRA Pro Grow Light, available on Amazon, is a great option. This grow light can provide the robust light necessary to keep your plants healthy and thriving.
  2. Maximize Light with Reflective Surfaces: You can enhance the benefit of your grow light with a reflective grow tent. The GIANTEX Grow Tent, also available on Amazon, is designed to reflect light, thereby maximizing the light exposure your plants receive.
  3. Know Your Plants’ Light Requirements: Different plants have different light needs. It’s important to understand these requirements and adjust your light source accordingly.
  4. Maintain a Consistent Light Schedule: Just like humans, plants have a circadian rhythm. They need a consistent light schedule to grow well. Make sure you’re providing your plants with light at regular intervals.

Grow up

Even though getting the light right is crucial, mastering the concept of vertical gardening can also significantly increase your indoor gardening success. When space is limited, you need to think creatively and vertically. Instead of sprawling your plants across the flat surfaces, consider stacking them upward.

You can start with small pots on the windowsill, but don’t let the limited horizontal space limit your indoor garden. Look up and see the potential. By organizing your pots vertically, you can grow more fruits, herbs, and veggies than you thought possible in your indoor space.

This can be as simple as positioning containers on boxes or stands of different heights. The key is to elevate the pots at the back high enough so the ones in front don’t block their light. The right arrangement ensures that each plant gets the light it needs without shadowing others.

Consider using a premade vertical garden stand, such as Outland Living’s Vertical Garden Bed, to maximize your vertical space. These stands are designed to hold multiple pots in a compact, vertical layout, increasing your growing capacity without claiming more floor space.

Remember, in vertical gardening, it’s not just about stacking pots. You need to consider the light needs of each plant and place them accordingly. Also, watering may need to be adjusted, as the pots at the top may dry out faster than those at the bottom.

Try a trellis

After mastering vertical gardening, it’s time to explore the use of trellises in your indoor garden. Trellises are a fantastic way to optimise your indoor gardening space, especially when you’re growing vining plants like green beans or cucumbers. These sprawling plants might take up a lot of room outdoors, but indoors, with the right guidance, they can grow compactly and efficiently.

  1. Choosing the right trellis: It should be sturdy enough to support the weight of your plants and their produce. Consider a trellis with a grid or lattice design which offers multiple points for the plant to cling to.
  2. Training your plants: Gently coax the plant’s tendrils around the trellis as they grow. This way, the plant will naturally follow the structure of the trellis, growing vertically instead of sprawling outwards.
  3. Support for heavy produce: When growing heavier fruits and veggies, like squash or cantaloupe, provide additional support with fabric slings. Tie these slings to the trellis under the developing produce to help bear the weight.
  4. Trellis placement: Place your trellis near a light source, ensuring your plant gets enough sunlight. But remember, avoid placing it near drafts or excessive heat.

Exploring the use of a trellis in your indoor garden is a practical and effective method to enhance your space. Not only does it help in managing vining plants, but it also adds an interesting visual element to your indoor garden. So go ahead, give trellises a try and watch your indoor garden thrive.

Water consistently

Now that you’ve got the hang of using a trellis, let’s dive into another crucial aspect of indoor gardening – consistent watering. Keeping your soil at the right moisture level is key for healthy plant growth. Fruits and vegetables, in particular, need to be grown in damp, but not soggy, soil. Irregular watering, where the roots are alternately wet and dry, can stunt root development and cause blossoms to drop off prematurely.

To keep your soil consistently damp, it’s important to check it daily. Press a finger onto the top of the soil. It should feel slightly damp and springy. If it’s dry, it’s time to water. You need to become familiar with each plant’s watering needs, as over-watering can cause as much harm as under-watering.

If you’re finding it difficult to maintain consistent soil moisture, you might want to consider using self-watering pots. These pots have built-in reservoirs that you only need to fill every seven to ten days. They dispense just the right amount of water to keep the soil damp, eliminating the risk of over or under-watering. A good option is the GARDENIX DÉCOR Self-Watering Planters, available on Amazon.

Maintain a stable indoor temperature

Just as your plants need consistent watering, they also require a stable indoor temperature to thrive. You’ve already taken the first steps towards creating a healthy indoor garden by watering consistently, but now it’s time to focus on temperature control. Each plant has a preferred temperature range, which is essential for its growth and development.

Understanding your plants’ needs is the first step towards maintaining a stable indoor temperature. For instance, many popular summer fruits and vegetables like tomatoes, peppers, cucumbers, and squash prefer it warm, around 75 to 80 degrees Fahrenheit. If you’re growing these, you may need to supplement the heat in your indoor garden, especially if your home is air-conditioned to below 70 degrees. A small space heater can help here.

On the other hand, cool-season plants such as lettuce, kale, and spinach prefer daytime temperatures around 65 to 70 degrees. These plants may wilt if the temperature exceeds 80 degrees. It’s crucial to monitor your indoor temperature and make adjustments as needed.

Here are a few practical tips to help you maintain a stable indoor temperature:

  1. Use a reliable indoor thermometer to accurately monitor your indoor garden’s temperature.
  2. Consider purchasing a small space heater or a cooling fan to adjust the temperature as needed.
  3. Keep your plants away from drafts, vents, or windows that might cause sudden temperature changes.
  4. Group plants with similar temperature requirements together for easier management.

Protect against pests

Every indoor gardener faces some level of pest challenges, but you don’t have to let these tiny invaders ruin your hard work. Even if you use a sterile potting mix, insects can still migrate from elsewhere in your home. Pests like fungus gnats can cause serious damage, feeding on your plants and potentially killing them.

You don’t have to resort to chemical pesticides to combat these threats. If you spot pests on your plants, consider using an organic pesticide, such as neem oil. This natural solution is widely available, including on popular online platforms like Amazon.

Alternatively, you can make your own safe pesticide at home. Mix 2 teaspoons of Dawn dishwashing liquid with 1 pint of water in a spray bottle. Spray this concoction on your plants, focusing on the foliage and soil. However, avoid spraying developing fruits or vegetables to prevent altering their flavor.

Remember, consistency is key when dealing with pests. Regularly inspect your plants for signs of infestation. Early detection is crucial to minimize damage and prevent pests from spreading to other plants. If you notice an infested plant, quarantine it immediately to protect the rest of your indoor garden.

Furthermore, maintaining a clean growing environment is another preventive measure. Regularly clean and disinfect your pots and other gardening tools to avoid attracting pests.

Dealing with pests can be frustrating, but with vigilance, the right tools, and a little patience, you can keep your indoor garden healthy and thriving. Remember, protection against pests is an essential part of indoor gardening success.

Control indoor humidity

Controlling indoor humidity is crucial for your indoor garden’s health, as high humidity levels can lead to increased fungal growth. When plants are clustered together, the humidity level often rises. If you notice moisture condensing on your indoor windows or the air feels sticky, it’s likely that the humidity level is too high and your indoor garden is at risk of fungal disease.

Here are four practical steps you can take to control indoor humidity:

  1. Open a Window: This is the simplest and most cost-effective way to reduce humidity. It allows moist air to escape and fresh, dry air to enter your room. Make sure to do this during the driest part of the day to avoid letting in more humid air.
  2. Use a Fan: Direct a gentle breeze towards your plants with a fan. This will facilitate air circulation and reduce humidity around your plants. Remember not to place the fan too close to your plants to avoid drying them out.
  3. Run a Room Dehumidifier: Products like the SHINCO Dehumidifier can effectively remove humidity from the air. Dehumidifiers work by drawing in moist air, removing the moisture, and then releasing dry air back into the room.
  4. Use Your Air Conditioner: Running your home’s air conditioner can also help reduce humidity. Air conditioners cool the air in your home by removing moisture from it.


In line with maintaining a thriving indoor garden, it’s essential that you provide your plants with the right kind of fertilizer. Unlike outdoor plants, your indoor plants depend entirely on the nutrients you provide as they grow in a soilless mix. It’s important to choose a fertilizer specifically designed for indoor fruits and vegetables, such as Miracle Gro’s Shake ‘n Feed Plant Food.

Follow the instructions on the label of the fertilizer to ensure you’re using it correctly. While some fertilizers need to be applied every two weeks, others like the Shake ‘n Feed only need application once every three months. This time-release fertilizer gradually provides the necessary nutrients to your plants, ensuring they grow and produce bountifully.

Remember, over-fertilization can be just as harmful as under-fertilization. Too much fertilizer can cause salt buildup in the soil, which can damage the roots and hinder the plant’s growth. Therefore, it’s crucial to stick to the recommended dosage and frequency.

Also, keep in mind that different plants have different nutrient requirements. Some may need more nitrogen, while others may require more phosphorus or potassium. Make sure you understand the specific needs of your plants to provide them with the right balance of nutrients.

Lastly, ensure that the fertilizer is mixed thoroughly with the soil for even distribution. This ensures that all the roots get an equal share of the nutrients. With the right fertilizer, your indoor garden will flourish, producing healthy, vibrant plants.


Indoor gardening is a rewarding endeavor that brings nature’s beauty inside.

Remember to choose suitable containers and the right soil.

Select plants that match your space and lighting conditions.

Engage in vertical gardening, maintain stable temperatures, and guard against pests.

Keep your indoor humidity in check and fertilize appropriately.

With these tips, you’re well on your way to cultivating a lush, thriving indoor garden.
