An Introduction to Indoor Vertical Gardening for Beginners

Getting into indoor vertical gardening is an excellent way to enjoy the perks of growing your own fresh produce, even if you're limited on outdoor space. Whether you're a city dweller or simply don't have a large garden, you can still cultivate vegetables, fruits, and herbs indoors. Indoor gardening extends beyond ornamental houseplants, offering a practical and rewarding solution. Let's explore the basics of starting your own indoor vertical food garden.




Why grow an indoor food garden?

Pros

If you're contemplating the suitability of indoor gardening, consider the multitude of advantages that have propelled its popularity. Cultivating a food garden, in general, is a splendid idea offering financial savings, eco-friendliness, and proven mental well-being benefits. Taste the difference of produce straight from the plant, free from industrial pesticides, early picking, long-distance shipping, and plastic packaging.

Indoor gardening proves to be an excellent solution for various situations:

  • No outdoor space is required, making it suitable for city apartments.
  • It's convenient for seniors or individuals with mobility challenges.
  • Vertical gardening allows you to maximize space indoors.
  • You have complete control over the entire growing process.
  • Indoor gardening is feasible year-round, unaffected by cold weather.
  • Greenery enhances the homeliness and natural ambiance of a space.
  • You can customize it to be as simple or sophisticated as you desire.

Cons

While there are some potential challenges to consider in the realm of indoor vegetable gardening, the benefits far outweigh them in my personal opinion. Most drawbacks can be overcome with a bit of creativity, so don't be deterred if the concept of cultivating your own food indoors appeals to you.

Potential considerations include:

  • Ensuring your indoor food garden is cat-proof or child-proof.
  • Adjusting to a different style of gardening, which may involve a learning curve.
  • Managing the potential expense of setting up larger systems with substantial lighting fixtures.
  • Taking precautions to protect walls or floors, particularly if you reside in a rental property.


Vertical gardening offers a multitude of benefits that maximize the utility of limited spaces. The ease of setup and maintenance, coupled with the lightweight nature of materials used, makes these gardens effortlessly movable and installable. Beyond their aesthetic appeal, indoor vertical gardens contribute to improved air quality, making them a practical addition to indoor spaces.

Benefits of Vertical Gardening

Environmentally conscious, vertical gardens prove to be more Eco-friendly than traditional counterparts by conserving water and utilizing less space. Outdoors, the elevation of plants simplifies maintenance tasks such as fertilizing, watering, pruning, and harvesting, providing both convenience and relief from potential physical strain.


Elevating plants off the ground not only enhances air circulation but also acts as a deterrent against pests, diseases, and damage caused by pet traffic or wildlife. Moreover, vertical gardens serve as an effective means of establishing privacy by concealing elements like air conditioners, garden sheds, or fences.


Transforming the appearance of a space, vertical gardens add character through diverse plant varieties, vertical displays, and vibrant blooms. They also assist in defining boundaries and creating a sense of privacy or seclusion, offering a versatile solution for both functional and aesthetic enhancements in any environment.

Types of indoor gardens

In the realm of indoor gardening, whether it's a traditional setup or a vertical garden, it's common to find individuals cultivating houseplants. Contemporary options for growing houseplants, such as vertical plant walls and greenhouse cabinets, not only serve a functional purpose but also contribute aesthetically to the space. However, it's worth noting that there are diverse types of indoor food gardens available as well. Vertical gardening options, in particular, offer space-saving solutions while still providing abundant yields of vegetables, herbs, or fruits.


As mentioned, the choice is yours whether to opt for a straightforward approach or to indulge in a more elaborate indoor gardening setup.

Simple DIY options

If you're comfortable with somewhat limited options, there are numerous straightforward indoor garden ideas that can be highly effective. Cultivate delicious herbs, leafy greens, microgreens, and more without stepping outside!

The best edible plants for indoor gardening

Numerous edible plants are suitable for outdoor cultivation, but size limitations may restrict the growth of tall crops such as corn or fruit trees. However, there's a vast array of small-sized vegetables, fruits (such as berries), and herbs to choose from. Consider exploring varieties that naturally have a compact growth habit or seek out dwarf cultivars within the plant species you find appealing.

Here are some of the plants I personally favor for an indoor food garden:

Microgreens: Perfect for beginners or those seeking a nutritious salad enhancement, microgreen seeds are affordable and effortlessly sprout, ready for harvest in just a few days.

Lettuce: Whether your preference is for romaine, arugula, oak leaf, or iceberg, lettuce remains relatively small and is an uncomplicated choice for indoor gardening.

Leafy greens: Spinach, chard, mustard greens, kale, and more—dark leafy greens, known for their health benefits, are straightforward to grow indoors.

Herbs: Classic choices like chives, basil, cilantro, and mint, or more exotic options like lemongrass, are ideal for an indoor garden, offering a fresher alternative to store-bought herbs.

Edible flowers: Considered both edible and decorative, flowers like pansies are an excellent addition to your indoor garden, bringing a splash of color.

Radishes: Among the smallest root vegetables, radishes require minimal space and are great for salads or pickling.

Green onion: As an alternative to larger onions, green onions (scallions) are a fantastic addition to various dishes and fit well within most indoor systems.

Mini carrots: While traditional carrots need deep planters, dwarf varieties like 'Thumbelina' offer a compact option for indoor gardening.

Strawberries: Ideal for hanging planters, strawberries can be cultivated indoors with relative ease.

(Dwarf) tomatoes: Although dwarf tomato varieties may not match the taste of heirloom tomatoes, they provide a compact option for indoor cultivation, and taller tomato cultivars can be accommodated if space allows.

Hot peppers: Similar to tomatoes, hot peppers, such as jalapeños, are part of the nightshade family and are suitable for indoor gardens. Micro peppers like Pequin and Biquinho are great for limited spaces.

Mini peas: Tom Thumb dwarf peas, an heirloom variety, remain small and are well-suited for indoor container gardens.


Additionally, with a well-structured indoor trellis and proper lighting, you can grow various small vining food plants like ground cherries, cucamelon, passion fruit, and even mini squashes that vine without becoming too heavy.

Setting up & maintaining vertical gardening systems

Now that you're aware, indoor vegetable gardening proves to be straightforward, especially with vertical gardens that require minimal space. A diverse range of vegetables and edible plants, including exotic options, can thrive in these setups. If you're prepared to learn about establishing and caring for your own vertical indoor garden, let's delve into the process.


Positioning

Selecting the right location for your indoor garden is paramount, particularly if you're considering a larger system that may be challenging to relocate later. Even for a small arrangement of pots, it's crucial to place them in a spot that receives ample light, unless you plan to use LED or fluorescent lights as supplementary sources (see below).


For significant indoor garden towers and similar setups, consider factors such as whether additional wall or floor protection is necessary, whether the lights may cause discomfort to your eyes, and where to position the unit for convenient access and maintenance.

Light

Lighting is a critical factor for indoor gardens, and in my experience, it's a common stumbling block for many aspiring urban gardeners. It's crucial to understand the amount of light a plant requires not only for survival but also for productive crop yields. Insufficient light can result in weak and leggy growth, making plants susceptible to disease and overwatering, ultimately leading to diminished yields.


Certain species, such as light-dependent tomatoes, may not thrive even in a window-side location. They either need outdoor exposure or a reliable artificial lighting system. Personally, I favor LED grow light panels, but it's essential to note that, despite their energy efficiency, they will still contribute to your electricity bill to some extent.

Soil & planting

Are you leaning towards a hydroponics system or sticking with traditional soil for your indoor garden? Each option has its advantages and disadvantages. Hydroponics conserves water and demands minimal upkeep, but it involves the task of nutrient mixing and pH balancing—although commercial kits often provide the necessary additives and instructions.


For soil-based cultivation, it's crucial to select a premium and well-aerated mixture. Additionally, ensure that planters come equipped with drainage holes to avoid potential rot issues caused by stagnant water.

Maintenance

Water

The frequency of watering your food plants varies based on factors such as species, light exposure, and planter size. For instance, Mediterranean herbs like rosemary prefer well-draining soil and dislike excessive moisture, while lettuce thrives in a fully hydroponic system, requiring a consistent water supply.

As a result, I can't provide a specific watering schedule for your crops. It's advisable to conduct research and closely monitor the soil. In general, most plants benefit from being kept lightly moist—never bone dry but also certainly not overly saturated.

Fertilizing

Nutrient management is crucial for cultivating delicious vegetables, herbs, and similar crops! Hydroponic systems, which don't rely on soil, come with specific instructions for nutrient application. For traditional cultivation, opt for a premium organic fertilizer to provide your plants with optimal nourishment. Follow the guidelines on the fertilizer bottle for optimal results.

If you have homemade compost available, incorporating it can be beneficial for your plants as well!

Pruning

In indoor gardens, where space is often constrained, occasional pruning or early harvesting may be necessary to manage plant growth. Since pruning needs vary among species, it's advisable to conduct some research on the specific plant you're tending to avoid unintentional damage.
