Best Plants to Grow on a Balcony

A small balcony should never limit your gardening objectives! The right plants can help you grow an exquisite vegetable and flower garden in pots. Following is the shortlist of the best plants that thrive in very small garden space while at the same time beautifying and adding freshness to your home. 

1. Swiss Chard

Swiss chard is the best leafy green to grow in a balcony garden. It is easy to grow, very nutritious, and stems of Swiss chard are pink, red, or yellow in color, adding beauty to the environment. Chard can be grown in pots of around **8-10 inches depth** in partial to full sunlight. Harvesting regularly will stimulate new growth, allowing farmers to enjoy continued production of fresh greens. 

2. Peppers (Bell and Chili)

Peppers, compact plants, grow well in pots. They require sunny conditions—**at least 6-8 hours of direct sunlight**—and well-drained soils. Choose small varieties such as Thai chilies or mini bell peppers for easy maintenance on your balcony. Keeping the soil moist and occasional fertilizing will guarantee a good harvest. 

3. Cucumbers

Cucumbers can save a lot of space if grown upright. They need a trellis or climbing frame to support their growing vines. Have a container of whatever dimensions you want; however, ensure that it is at least 12 inches deep. The sun should be on them, and with regular watering, they should be fine. Varieties such as “Patio Snacker” or “Bush Champion” are a small-space gardener’s best friends. 

4. Sweet Pea Flowers

Sweet peas are not just lovely flowers, they attract other pollinators like bees and butterflies, too. They are happy with cooler weather and do need some manner of support, such as a trellis or a railing, in order to grow. When provided with support and kept in moist, well-drained soil, they bloom in lovely shades of pink, purple, and white, creating a charming aspect of your balcony. 

5. Cooking Nasturtium 

Nasturtiums are edible flowers that are both beautiful and useful in the kitchen.

Setting Up a Balcony Garden

Setting up a balcony garden for success begins with the right set up. Here is how to do it, fast and efficient.

1. Picking the Right Structure

Use deep pots (10-12”) for vegetables, and shallow pots (6-8 inches) for herbs.

Make sure there are good drainage holes to prevent root rot.

Consider going vertical with planting options like planters or hanging pots to save space.

2. The Best Soil Mix for Containers

Lightweight potting mixes would support better drainage.

A mixture might be 50% potting soil, 30% compost, and 20% perlite/sand: coconut coir for moisture retention is also an option. Organic fertilizer is optional but would also add nutrients.

3. Sunshine & Positioning

Full sun (6-8 hrs): Peppers, cucumbers, Swiss chard

Partial sun (3-5 hrs): Celery, garlic, ginger

If less illumination exists, mirrors or other reflective surfaces may be used to brighten the area up.

4. Watering & Drainage

While on hot days, irrigation may be required, on cooler days, it may be less.

Self-watering pots and mulch may also be used to help retain moisture.

Waterlogging may be avoided if proper drainage is provided for the pots.

Maintenance Tips for a Thriving Balcony Garden

Keeping your balcony garden healthy requires regular care. Here are three key maintenance tips to ensure continuous growth and a bountiful harvest.

1. Regular Pruning and Harvesting

  • Trim dead or yellow leaves to promote new growth.
  • Harvest vegetables and herbs on time to encourage more production.
  • Prune trailing plants like cucumbers and sweet peas to control size and improve airflow.

2. Fertilizing for Healthy Plant Growth

  • Use organic compost or liquid fertilizers every 2-3 weeks for essential nutrients.
  • Leafy greens need nitrogen-rich fertilizers, while fruiting plants like peppers and cucumbers require potassium and phosphorus.
  • Avoid over-fertilizing, as it can burn plant roots and reduce growth.

3. Rotating Crops to Prevent Soil Depletion

  • Change plant placement every growing season to maintain soil health.
  • Avoid growing the same type of plants in one container continuously, as it can drain specific nutrients.
  • After harvesting, refresh soil with compost or organic matter before planting new crops.
