Thank you, Pallabi. Glad you liked the pictures so much and it inspired you a little bit. I’ve also been inspired likewise by pictures and stories from other rooftop gardeners. And yes, do post your own pictures.
Since I posted the pics I’ve harvested one more winter season of crops from the rooftop though summer crops have been a challenge. We did plant Gongura, Brinjal, Amaranth and Colocasia (arbi) after the onset of monsoons this year.
Now in the third winter season we’ve planted some more cauliflower, lettuce, beetroot, onion, tomatoes and green chillies. We upgraded the containers to nursery grade plastic bags of two sizes (14" and 8" dia) filled to 6-7" height after transporting another round of soil to the roof which is the most laborious part of the whole deal. We also put some more soil into the flat beds and raised its height from 4.5" to almost 6".
I apply Jeevamrit to the plants occasionally (though I need be regular) with the cow dung and cow urine procured from nearby Gaushala (cow-shed). Pests have been a problem only with Brinjal crop which still managed to survive the attack. I sprayed a soap-oil combination which didn’t help. Regardless, the Brinjal produce was fine.
You should get Broccoli seeds at any nursery that keeps vegetable seeds. No particular attention need be paid to soil composition as long as it is well drained and the location receives at least 5-6 hrs of sunlight during the day.
I don’t know the period of growing Broccoli in Bangalore but for Delhi, its a little late to plant from seed. Like cauliflower, the seeds should be sown in Sept-Oct and transplanted by Oct-Nov. I guess Bangalore winter being mild, you may still have time.
