Balcony Gardening: Notes from the Green-ish Thumb

by Kyra Fant

Growing herbs and plants on my apartment balcony has become one of my favorite things in the world. That said, it’s a passion that has come with a significant learning curve.

It's a little hard to admit, but despite having parents with certified green thumbs, my own journey has been... well, let's just say I've cultivated a small, respectable plant graveyard. My primary challenge is an apartment balcony that faces the intense, direct Florida sun—a microclimate that some plants find glorious and others find to be a personal affront.

These experiences (RIP, fussy plants) have been my best teacher. Here is a practical overview of what I've learned.

Herbs That Can Take the Heat

Through much trial and error, I've found a few heroes that perform well in containers, even with significant sun exposure.

Mint: This is an ideal container plant. Its naturally invasive root system, which is a garden-bed nightmare, is a total win in a pot. Mint enjoys the sun, but I’ve learned it has two demands: ample pot space and consistent, regular watering. I've had a lot of fun with this, growing varieties like banana mint, candy mint, orange mint, and apple mint.

Greek Oregano: This is another sun-lover that has proven to be incredibly resilient. It will grow prolifically if you let it, handling the direct sun well.

Cuban Oregano: This plant is truly obsessed with the Florida sun. Its thick, succulent-like leaves seem to just soak it up, making it one of the easiest and most robust herbs for a hot, sunny spot.

Lemon Thyme: This has been a pleasant surprise. So far, my lemon thyme has liked the heat and is doing well, adding a fantastic citrusy scent to the balcony.

Spinach: I have been pleasantly surprised by spinach. You can get just about any common variety to grow successfully in a container. It's reliable and provides fresh greens without a lot of drama.

The Learning Curve: Strategic Placement is Key

A key lesson for me has been that not all plants are created equal, especially when it comes to direct sun.

The Failure (Rosemary): My nemesis. I have had very little luck with rosemary. While it's known as a tough, Mediterranean herb, it simply does not appreciate the relentless solar blast on my balcony. It just gives up.

The Indirect-Light Successes (Guava & Coffee): On the other hand, I have a guava tree that I absolutely love, and it genuinely enjoys the heat. However, it hates direct sunshine. If it gets hit with those harsh afternoon rays, it immediately tries to kick the bucket. It now lives in a bright spot that is shielded from the most intense, direct light. My coffee plant is the same, preferring bright, indirect light where it can thrive without getting scorched.

Helpful Tidbits for Balcony Gardening

1. Watering is Your New Part-Time Job: Plants in containers, especially in direct sun, dry out incredibly fast. Check the soil moisture daily. Watering bulbs have been an absolute saving grace for me, helping to keep the soil consistently moist, especially for the thirstier plants.

   
   

2. Use Good Compost: I plant all my containers with compost. This is non-negotiable for me. It not only provides essential, slow-release nutrients but also dramatically improves the soil's water-holding capacity.

   
   

3. Container Choice Matters: Ensure every pot has drainage holes. Terracotta pots look great but dry out very quickly. Glazed or plastic pots retain moisture longer.

   
   

4. Observe Your Microclimate: Every balcony is different. Pay attention to how the sun moves, where the wind hits, and which areas get reflected heat. Adjusting a plant's position by just a few feet can make all the difference.

Balcony gardening is a process of observation and adaptation. While it hasn't always been easy, the reward of harvesting something you've grown yourself makes every challenge worthwhile.
