Living in the city and having a nice garden is such a wonderful idea, but how do you do it when the city is packed with so many buildings? Since there’s no more space, you can opt for a rooftop garden. Here are some steps you can follow to make one.

Things you’ll need:

Soil
Plants and flowers
Insulation layer - This is where you place the soil.
Waterproof barrier
Root barrier - Use this to avoid the roots from going through the waterproof layer.
Clay, gravel or plastic- This is where the water drains.
Filter- This prevents soil erosion.

Steps:

Check if it’s safe to make a rooftop garden on your home or building.
- Talking with an architect would be a great idea. You have to know if the roof can hold the added weight of a garden.
- If you’re living in an apartment or leasing a house, it’s good talk to the owner about your plans.
- This type of garden also requires a flat area. A roof that slopes isn’t advisable.
Choose the sunniest part of the roof. This will ensure that your garden will receive enough sunlight.
Set the foundation layers and barriers.
- Use a plastic sheet as the base layer.
- Lay down the water proof barrier and then the root barrier.
Select the plants and flowers you want to grow.
- Choose those that are not sensitive to harsh weather, as they will be exposed to rain, cold and heat everyday.
- Using plants that commonly grow in the area is a good choice. These plants are already accustomed to the weather changes in your city.
- Use plastic or clay pots for your plants.
Decorate your rooftop garden.
- If you have enough space, you may add gazebos, trellis, tables and benches.
  You have to be cautious in using decorations.
- Your roof may not be able to hold the additional weight, if you use heavy materials. This is why consulting with an architect is important.
