When you look at the roof of most houses, you can see different types of gardens. Here we discuss the Method of Rooftop garden in NYC with the care of the roof garden.
However, most of these gardens have been developed unplanned. It is possible to grow any tree or even vegetables on the roof of the house if the initiative is taken in a planned manner.
To garden successfully on the roof, you need to know what kind of soil is suitable for which tree, choose a tree that can withstand the heat or the sun. In addition, the garden needs to be properly watered and cared for properly.
Roof gardening materials:
An empty roof; Half drum, cement or earthen tub, plastic stray; Permanent bed in a convenient place on the roof (space should be left between the roof and the bed); Scissors, spades, scissors, showers, buckets, saws, spades, knives, hand spray machines, etc. Sandy loam or hilly red soil, rotten dry dung and compost, sand and brick cobbles, Seedlings/cuttings or seeds etc.
Trees suitable for making a rooftop garden in NYC:
When gardening on the roof, it is important to make sure that the tree is not too big. Hybrid varieties or pen trees can be planted in small size trees to get more fruits. The fastest growing and fruit-bearing tree of the short species is the best for roof gardens. When seedlings are planted, not seedlings, very fast results are obtained. It is better to plant hybrid varieties for roof gardens.
Fertilizer soil preparation for Rooftop garden in NYC:
First loam and sandy loam soils should be collected. Then the soil should be purified. For purification, take a sufficient amount of soil and sprinkle water mixed with formaldehyde (100 ml/litre of water) and cover the whole soil with thick polythene for 3-4 days. After removing the polythene, the soil should be kept open in sunlight for 3-4 days. When the smell of formalin is over, the same amount of dung or organic manure, if necessary, chemical manure should be mixed to make compost soil.
Method of roof gardening in NYC:
This is considered to be an easy method as it can be easily moved from one place to another. However, the size of the tub is usually not very good for fruit trees.
Fruit trees can be planted in large tubs. In that case, large tubs made of cement can be used. Adequate amounts of organic manure should be used for tub cultivation.
Organic fertilizer for a tub of size 14 inches to 18 inches plus 100 g TSP and 50 g MOP fertilizer should be well mixed and left for 10-12 days. Then the tub needs to be filled.
At present most people grow orchards on the roof in the half-drum method. A hole should be made at the bottom of the half-drum. Pieces of brick should be placed in the holes; The top of the drum should be covered with the first 1 inch of concrete and the top with an inch of organic manure or rotten dung. This allows excess water to drain out easily.
In addition to organic fertilizer, 200 g TSP, 100 g MOP can be used in each drum. In addition to the above organic and chemical fertilizers, 500 g of bone powder can be used in each drum for mango and lemon trees. Vegetables, even small tubs or pots for flowers. But in the case of fruit, the bigger the pot/drum, the better.
Permanent bed method: Permanent bed method is a modern method for roof gardening. Before gardening on a permanent bed system, the roof should be specially welded and net finished. There are two methods. E.g.
1.Permanent bedding around the roof method: In this method, for gardening, 1.5 feet high walls on both sides of the roof are made by casting a 3-inch masonry net finish on both sides of the space. After giving the next one inch of dung manure, the remaining part is filled with a mixture of 2 parts soil and 1 part dung to make a permanent bed. Excess water, fertilizer should be kept in a proper way.
2. Tank method: Trees can also be planted on the roof in the tank method. That is why the water tank is made of 3 feet long, 2 feet wide and 1.5 feet high 3-inch masonry net finish on 4 pillars one foot high on the roof. This is called the tank bed method.
Rules for planting trees:
Seedlings / cuttings should be planted very carefully in tubs / pots / drums / permanent beds. It should be planted just below the ground in the middle. Care should be taken to ensure that the soil ball attached to the seedling or pen does not break.
In case of seedlings or cuttings, the seedbed or nursery should be planted on the roof as much as it is below or below the ground. Planting more or less deeper than the seedbed can cause problems in plant growth.
Irrigation or drainage is an important aspect of the roof garden. This is because if the soil moisture decreases, just as the plants can be easily removed, the trees can also be killed due to excess water or moisture.
For this, water can be given only when the root of the tree is dry, if the root is wet, it cannot be watered in any way. Therefore, the roof garden must be constantly aware of irrigation.
At the base of the tree so that water does not accumulate. It is better to irrigate the roof garden with thin plastic pipes or grate. Irrigation must be given in the morning.

Pruning scissors: The roof garden should be kept clean and tidy at all times. That is why old diseased, old stalks, leaves should be carefully cut and deposited in a certain place. This will keep the plant’s disease-free and the growth and yield of the trees will be good.
In the case of cool trees, all the branches of the tree should be pruned in the middle of the month of Falgun after eating cool. In addition, dead and diseased stalks should be cut and applied board paste.
Loosen and mulch :
Loseen and mulch the soil of the poles and tubs of the trees. This will prevent the tree from tilting or weakening by moving. The upper layer should be broken by weeding after 15-20 days. As a result, weeds can be controlled and ventilation inside will be facilitated.
In the dry season, mulching with dried water hyacinth or straw, dry leaves on the four sides of the roots of long-term large trees will preserve the sap, prevent grass growth and later use them as decomposing fertilizer.
Changing the soil of the tub or drum:
This is also an important part of the roof garden, usually, the work can be done at the end of the monsoon. Before that, some sand should be mixed with two parts of two-fibre or two-part soil.
Approximately 40 gms of TSP, 40 gms of potash, 100 gms of bone powder at the rate of 10 gms of mustard oil should be mixed with the soil and left with water for 10-12 days for each tub. Then the soil in the tub that needs to be changed should be thrown 2 inches wide and 6-8 inches deep near the tub of the tree. This applies to 18-20 inch tubs. After removing the old soil, the place should be filled with pre-prepared soil.
Proper position of the tree:
Some trees prefer more sun (paper lemon, dragon fruit), some trees are better in semi-shade (cardamom, lemon), some trees prefer shade (Latkan, Rambutan). Therefore, to get more benefits from the roof garden, it is necessary to finalize the position of the tree by understanding the condition of getting sun / light air on the roof.
Fruit trees should be fertilized at least twice a year, for example, before and after the monsoon. The use of water to wash fish, meat and vegetables is used to fill the lack of food in the plant.
It is also good to apply mixed fertilizers, bone meal and nutrients (zinc, boron, magnesium, manganese) once a year. Fish thorns, bone fragments, eggshells, discarded vegetable parts, leaves, wrapped in a drum is good to use in the roof garden.
It is also best to use Trichoderma, earthworm manure, quick compost, and other organic fertilizers available in the market in the roof garden. Trees can be made healthier by removing them from relatively smaller tubs to larger tubs. A variety of nutrients/hormones (Sylvamix, Litosen, Flora) can be applied to prevent flowering and fruit set.
Insect and spider control:
In the initial stage, a limited number of insects or their eggs are seen in the beginning. It is better to collect insects or insect eggs and kill them only after checking the roof garden regularly.
Insects are located in the lower part of the leaves. In many cases, the insects take shelter in the adult leaves for a long time. For this, as soon as the leaf turns yellow, it has to be pruned leaving the leaf bud. Soak 2-3 gms of very spicy chilli powder in one litre of water and sift it the next day. Mix 2 gms of detergent powder and one teaspoon of onion juice in it and spray at intervals of 7-10 days. By the organic method, the plant can be kept safe from insects Mites or tiny spiders cannot be seen with the naked eye.
Lychee, chilli, eggplant, marigold flowers are more prone to mite infestation. This spider can also be controlled by the pepper powder method.
Since the location of the insects is under the leaves, effective measures should be taken to control the insects by spraying this part well. It is better not to use pesticides in the roof garden.
However, if pesticides have to be used, care must be taken to ensure that their toxicity is short-lived (deltamethrin can be grouped but not imidacloprid group).
