Rooftop Gardening Ideas, Tips, and Techniques.
Today, let us get into rooftop gardening ideas for beginners. What is a Rooftop garden? The Rooftop garden also known as terrace garden or balcony garden; it is a garden that is used to grow vegetables, fruits or flowers on the terrace, balconies or roof of buildings. The kitchen garden, a standard in every Indian household, has shifted to the roof due to constraints of space, & called a terrace garden.
A Rooftop or terrace garden is a garden on the roof of a building. Rooftop farming is generally done using green roof, hydroponics, aeroponics or air-dynamics systems or container gardens. Rooftop gardens are man-made green spaces on the topmost levels of industrial, commercial, & residential structures. They may be designed to grow to produce, provide play space, give shade and shelter, or basically be there as a living, green area.
Two main divisions of Rooftop garden types exist, these are extensive and intensive. Extensive gardens require minimal maintenance & behave as another form of roofing material. They are not intended for heavy foot traffic nor do they want to meet any additional safety standards.
The other extreme includes intensive gardens formed with the intent of active human use. These gardens require landscaping & regular upkeep. In some cases, the roof structure must be reinforced during the addition of decking or additional bracing to accommodate the joint weight of soil, plants, & precipitation. Furthermore, intensive gardens may also want to comply with safety regulations regarding decks and public areas on raised structures. These regulations may need some kind of fencing or barrier to being installed with the intent of preventing people from slipping over the edge of the roofline. If you have decided to design a terrace garden, you must have collected the appropriate containers, potting mix, manure, etc. The containers used in the rooftop garden of all sizes, shapes, whether of plastic, ceramic, metal or mud can be used. One should have rooftop gardening ideas for creating beautiful garden.
Rooftop garden design tips:
Soil and compost: To start with fill the pots with potting mix and include composted cow manure. If you have enough space, you can create your own compost; place the compost bin in a corner of the terrace or roof. This way you will be using all the kitchen scraps for creating the most nutritional mix for the pots. Do not try to begin with seeds. Buy seedlings from the nursery & plant them. This way you will save at least one month, besides saving yourself from frustration because of failure in growing seedlings (increasing vegetables from seeds).
Put the pots in appropriate locations, the sun-loving plants in sun & the shade plants in shade. Most of the vegetables thrive in the sun, but there are a few which grown shade. You may plant a few seasonal plants & a few perennial plants. Put trellises on climbers such as cucumbers, bottle gourd, bitter melons, jasmine plants, and etc. You can train these vines to climb on strings.
Watering: Watering the plants deeply daily, maybe twice in the summers. Put a 3 to 4-inch layer of organic mulch such as sugar cane mulch on the soil. This will keep the moisture inside the soil & also prevent the weeds.
Add some water crystals in the soil while planting or extend them on the surface. Plant drought-tolerant plants to decrease the frequency of watering. Do not grow plants that have deep & aggressive root systems.
The plants need frequent feeding. I feed with liquid fertilizer, high in potassium and low in nitrogen every ten days. High nitrogen will generate excessive leafy growth, while potassium will encourage flowers and fruits. You may buy, a common purpose fertilizer for vegetables and flowers, a slow-release fertilizer or a liquid fertilizer.
When it comes to rooftop garden plan, ensure you maintain the diversity in the size of the plants. A few large plants, shrubs & small trees, ground covers, annuals must be there. Also, buy containers of different sizes this will provide a great look for your rooftop garden.

During the evening, it is very important that your rooftop garden is well-lit. Especially near the stairwell or door, it’s nice to create more bright spots. Moreover, lighting a roof will create it look larger during dusk.
The nice floor is important
Don’t neglect the flooring. Prefer flooring type that fits your budget, suits the climate you live in and accommodate the theme of the rooftop garden.
