Top 11 Indoor Urban Garden Ideas to Start in Your Small Apartment
Living in the city has its perks—the energy, the convenience, the endless opportunities. But for those of us with a green thumb (or the aspiration for one), a small apartment can feel like a concrete box, far removed from the lush gardens we dream of. You look at your compact kitchen, your cozy living room, your single sunny window, and think, "Where could a garden possibly go?"
That feeling is universal among city dwellers. The desire to connect with nature, to cultivate something living, and to taste the unparalleled freshness of food you've grown yourself doesn't disappear just because you don't have a backyard. The good news? You don't need one. Your small apartment isn't a limitation; it's a canvas for creativity. Modern urban gardening is all about innovation, efficiency, and making the most of every square inch.
So, get ready to transform your living space into a thriving, green oasis. We've curated the top 11 indoor urban garden ideas that are perfect for small apartments. Whether you have a sun-drenched windowsill or a shady corner, there’s an idea here that will inspire you to start digging in (metaphorically, of course).
1. The Classic Windowsill Herb Garden
Let’s start with the gateway to indoor gardening: the humble windowsill herb garden. It's iconic for a reason—it’s simple, incredibly rewarding, and requires minimal space. There's nothing quite like snipping fresh basil for your pasta sauce or mint for your evening tea, all sourced directly from your kitchen window. This is the perfect starting point for any budding urban gardener.
To get started, all you need is a window that gets at least 4-6 hours of direct sunlight per day. South-facing windows are ideal, but east or west-facing ones work well too. Choose herbs that you love to cook with. Think basil, parsley, rosemary, thyme, chives, oregano, and mint. Just be sure to give mint its own pot, as it's an enthusiastic grower that tends to take over!
Get Started Tip: You can buy starter plants or grow from seed. For beginners, starter plants provide an instant sense of accomplishment. Ensure your pots have good drainage holes at the bottom and use a quality potting mix. Water when the top inch of soil feels dry, and you'll be on your way to a fragrant, delicious harvest.
2. Vertical Gardening & Living Walls
When you can't build out, build up! Vertical gardening is a game-changer for small apartments, turning a blank wall into a productive and stunningly beautiful feature. A living wall not only saves precious floor space but also acts as a natural air purifier and a piece of living art. It’s a statement piece that’s as functional as it is beautiful.
There are many ways to create a vertical garden. You can buy pre-made systems with felt pockets, modular stackable planters, or wall-mounted shelving. For a DIY approach, you can repurpose a wooden pallet or hang a series of individual pots on a trellis. This method is perfect for growing leafy greens like lettuce and spinach, strawberries, and a variety of herbs.
Pro-Tip: Choose your plants based on the amount of light your wall receives. For lower-light areas, consider ornamental plants like pothos, ferns, and philodendrons. If you have a bright spot, go for edibles. Drip irrigation systems can be a lifesaver for larger living walls, ensuring every plant gets the water it needs without making a mess.
3. Hanging Baskets for Edibles & Ornamentals
Look up! The space above your head is often the most underutilized real estate in an apartment. Hanging baskets draw the eye upward, creating an illusion of height and filling your room with cascading greenery. They are perfect for placing in front of windows or in empty corners, adding life without cluttering surfaces.
While classic choices like spider plants and English ivy are beautiful, don't be afraid to think beyond ornamentals. Certain edibles thrive in hanging baskets. Vining cherry tomato varieties (like 'Tumbling Tom'), strawberries, and even some types of peppers can be surprisingly productive. The key is to choose a sturdy basket with a good liner and a reliable hook secured to a ceiling joist.
Get Started Tip: Hanging baskets tend to dry out faster than regular pots, especially in warm, dry indoor air. Check the soil moisture daily and water thoroughly when the top inch is dry. A watering can with a long spout will make reaching them much easier.
4. Terrariums: A Miniature Glass Ecosystem
For those who love the idea of plants but worry about the upkeep, a terrarium is the perfect solution. These self-contained miniature gardens in glass containers are not only mesmerizing to look at but are also incredibly low-maintenance. They create their own microclimate, recycling water through evaporation and condensation.
There are two main types: closed and open. Closed terrariums are perfect for moisture-loving tropical plants like mosses, ferns, and nerve plants, as they create a humid, self-watering environment. Open terrariums are better suited for succulents and cacti, which prefer dry conditions and good air circulation. Building a terrarium is a fun, creative project that allows you to design your very own tiny world.
Pro-Tip: The most important layer in a terrarium is the drainage layer. Start with a base of small rocks or gravel, followed by a thin layer of activated charcoal (to keep it fresh), and then your potting medium. Place them in a spot with bright, indirect light, as direct sun can scorch the plants inside the glass.
5. Hydroponics: The Soil-Free Future
Ready to step into the future of gardening? Hydroponics is a method of growing plants without soil, using nutrient-rich water instead. This might sound like something out of a science fiction movie, but compact, user-friendly hydroponic systems are now widely available for home use. They are incredibly efficient, often resulting in faster growth and larger yields than traditional soil gardening.
These systems are perfect for small apartments because they are clean, self-contained, and can be placed anywhere, even in a room without windows (most kits come with built-in LED grow lights). They are fantastic for growing leafy greens like lettuce and kale, herbs like basil and cilantro, and even fruiting plants like tomatoes and peppers, all year round.
Get Started Tip: For beginners, an all-in-one countertop hydroponic kit (like an AeroGarden or similar brand) is the easiest way to start. These kits come with everything you need, including the light, pump, and pre-seeded pods. Just add water and nutrients, and watch your garden grow.
6. Microgreens on Your Countertop
If you're looking for a quick, nutritious, and incredibly space-efficient crop, look no further than microgreens. These are the young seedlings of edible vegetables and herbs, harvested just after the first true leaves have developed. They are packed with flavor and nutrients—often containing higher vitamin concentrations than their mature counterparts.
Growing microgreens requires nothing more than a shallow tray, a growing medium (like coconut coir or potting soil), seeds, and a little bit of light. You can grow a huge variety, including broccoli, radish, kale, arugula, and sunflower. From seed to harvest, the process usually takes only 7 to 14 days, providing a near-instant sense of gardening success.
Pro-Tip: Sprinkle your seeds densely over the moist growing medium, gently press them down, and cover the tray for a few days to encourage germination. Once they sprout, uncover them and place them on a sunny windowsill or under a grow light. Harvest with scissors when they are 1-3 inches tall. They are perfect for adding to salads, sandwiches, and smoothies.
7. Sprouts in a Jar
Think microgreens are fast? Sprouts are even faster and require even less space. Sprouting is the practice of germinating seeds to be eaten raw or cooked. The entire process takes place in a simple glass jar, making it one of the most accessible forms of urban gardening. You can have a fresh, crunchy harvest in just 3-5 days.
All you need is a wide-mouth mason jar, a sprouting lid (a mesh screen that allows for drainage), and sprouting seeds like alfalfa, mung bean, broccoli, or lentil. The process involves soaking the seeds, then rinsing and draining them twice a day until they've grown little tails. It's a fascinating process to watch and a fantastic way to add fresh, living food to your diet.
Get Started Tip: The key to successful sprouting is airflow and drainage. After each rinse, make sure to drain the jar thoroughly and store it upside down at an angle (propped in a bowl) to allow excess water to escape and air to circulate. This prevents mold and ensures healthy, crisp sprouts.
8. Mushroom Growing Kits
For a truly unique indoor gardening adventure, try a mushroom growing kit. These kits come with a block of substrate (like sawdust or coffee grounds) that has already been inoculated with mushroom mycelium. Your job is simply to provide the right conditions—usually just humidity and indirect light—and watch the magic happen.
Growing your own gourmet mushrooms like oyster, shiitake, or lion's mane is surprisingly easy and incredibly rewarding. Within a week or two of starting your kit, you'll see tiny pins emerge, which quickly grow into full-fledged, delicious mushrooms ready for your frying pan. It’s a fun project that feels more like a science experiment and yields a delicious result. As my colleague Goh Ling Yong often says, "Gardening should be an exploration, and mushrooms are a whole new world to discover."
Pro-Tip: Most kits just require you to cut an 'X' in the bag and mist the area with water a few times a day. Place the kit in a spot away from direct sun and drafts, like on a kitchen counter. You can often get a second or even third harvest (flush) from a single block.
9. Container Gardening with Upcycled Finds
Container gardening is the foundation of apartment horticulture, but it doesn't have to mean rows of generic terracotta pots. Get creative and find beauty in the unconventional. Almost any container that can hold soil and has drainage can become a home for a plant. Think vintage tea tins for succulents, colanders for herbs (they have built-in drainage!), or colorful painted buckets for a dwarf lemon tree.
This approach not only saves money but also allows you to infuse your personal style into your garden. Larger containers like fabric grow bags are excellent for growing bigger plants like potatoes, carrots, or even a small blueberry bush. They are lightweight, provide excellent aeration for the roots, and can be folded away when not in use.
Get Started Tip: The non-negotiable rule of container gardening is drainage. If your chosen container doesn't have holes, you must drill some. Without drainage, water will pool at the bottom, leading to root rot, which is a swift end for any plant.
10. Aquaponics: A Fish & Plant Partnership
If you're intrigued by hydroponics and also happen to love fish, aquaponics is the ultimate indoor gardening system for you. It's a symbiotic ecosystem in a box. In this closed-loop system, fish produce waste, which is rich in ammonia. Beneficial bacteria convert that ammonia into nitrates, which is the perfect fertilizer for plants. The plants, in turn, absorb these nutrients, cleaning the water for the fish.
It’s a beautiful, self-sustaining cycle that is both educational and highly productive. Small, attractive tabletop aquaponics systems are available that function as both a planter and a fish tank. They are perfect for growing herbs and leafy greens on top while enjoying the calming presence of a betta fish or guppies below.
Pro-Tip: When starting an aquaponics system, the system needs to "cycle" to build up the beneficial bacteria colony. Be patient during this initial phase. Start with hardy plants and feed your fish sparingly until the system is established and balanced.
11. Kokedama: Japanese Moss Balls
For a final touch of artistry and elegance, consider Kokedama. Translating to "moss ball" in Japanese, Kokedama is a unique style of bonsai where a plant's root system is wrapped in a mud ball, then covered in soft green moss and bound with string. The result is a living, sculptural art piece that can be hung or displayed on a decorative dish.
Kokedama is a wonderful way to display plants without a traditional pot, adding a minimalist and natural aesthetic to your home. They are perfect for humidity-loving plants like ferns, pothos, and orchids. Caring for them is simple: just soak the entire moss ball in a bowl of water for 10-20 minutes when it feels light and dry.
Get Started Tip: Making your own Kokedama is a fun and surprisingly easy DIY project. You’ll need akadama soil, peat moss, a small plant, sheet moss, and string. There are many great online tutorials that can walk you through the meditative process of creating your own botanical sculpture.
Your Green Journey Starts Now
Living in a small apartment should never be a barrier to the joy of gardening. As you can see, a lack of a backyard just pushes us to be more creative, more innovative, and more connected to the green life we bring indoors. From a simple pot of basil on the windowsill to a sophisticated aquaponics system, there is a path for everyone to cultivate their own personal oasis.
Don't feel overwhelmed by the options. My advice, and something we always emphasize here on the Goh Ling Yong blog, is to start small. Pick the one idea that excites you the most, gather your materials, and just begin. The act of planting a seed and watching it grow is one of life's simple, profound pleasures.
