My name is Yusuf. I live in Riyadh, Saudi Arabia (capital). Recently started my rooftop garden, applying Permaculture principles (I am a student at Regenerative Leadership Institute). While we are at the onset of summer, the peak temp is reaching low 40's at noon. Currently I have the following plants on my garden:
Zuchini, cucumber, bitter melon, okra, kangkong, sweet potatoes, roma and cherry tomatoes, zinnia, job's tears, napier grass, guava, mullberry, lemon, fig, hibiscus, cilantro, sweet and purple basil, talinum, rosemary, roses, amaranth, cucumber, watermelon, some annuals.
For my plants in pot, I practice sub-irrigation where almost all my pots does not have direct drain hole at the bottom, instead, the drain holes are around a couple of inches from the bottom of the pot. I put perlite as subtrate in the water reservoire. This helps me water only ever other day during these hot summer days , or after several days during winter.
