Anne Harvey, owner of Herndon Florist, also recommends putting the plant in a bathtub and turning on the shower nozzle to wash away unwelcome guests. Harvey once designed a garden for her own apartment balcony that featured a small fiberglass pond. The ponds hold about five gallons of water. Harvey's pond bubbled and was surrounded by rocks, ferns and other blooming plants. She set out candles and had just enough room for one chair and a table, making for an inviting retreat.
Gardeners can even grow miniature roses or ficus trees on their balconies.
Harvey recommends wrapping white lights around a ficus tree for a decorative effect, and adding potted plants for color. It makes you forget you've got a small space. Creating privacy in a balcony garden can be difficult, as it is hard to grow larger plants, Fish said. However, you can add some privacy to your space by growing vines over your railings if your balcony is in the sun, or putting up hanging plants with dangling foliage if your balcony is in the shade. Fish said balcony gardens can provide hours of enjoyment.
