Planning a Rooftop Home Herb Garden
Before planting, study the condition of the roof, the structure and the capacity of the load it can withstand. Determine the weight of the herb garden and the cost associated with it. Consider the special requirements of a green roof system, irrigation, drainage and selection of herbs and maintenance. Obviously you may not want to go for heavy, bushy shrubs and plants. Identify the area for the rooftop garden; this has to be stepped up from the terrace slab in order to take care of the various layers of filling that is rudimentary requirement of a terrace garden.

Designing the Slab and Drainage
It will be prudent to consult a structural or civil engineer for the guidance of extra strengthening of slab and providing a water-proof rooftop to avoid damage to the roof when the herbs are grown to their full potential. To prevent water seeping it is better to do a chemical based water-proof than a membrane based for excellent results. The final layer of concrete should be put only after the water-proofing. For drainage, perforated pipes have to be laid over the slab. Next is the layer placement comprising gravel, brickbats and sand followed by a filter fabric which is fundamentally a thick sheet where a stone grid is laid out. This is necessary to hold the earth in place by checking soil erosion and ensuring a good draining system that is not clogged by silt.

Soil and Manure
The layer of soil should be about six to nine inches deep to ease the roots to grow underneath the earth’s surface. Plants with invasive tap roots are not suited for rooftop gardens; they may even penetrate the waterproof membrane causing damage to the roof slab. Herbs that grow shallow roots and require less water should be preferred. Once the earth is laid, it is time to sow the seeds and the saplings according to the season.

Wind Break System

Arrangements have to be made to shelter the herbs with fences and barriers. High walls can be built around the borders to shield and guard from wind-storms. Strong winds constantly dry out the soil along with hot sun, often plants need watering 2 or 3 times a day. Pergolas, lattice fences, laths and wood panels should be erected to provide shade to the scorching herbs but care should be taken to allow the essential warmth of the sun-rays and air.
