You may not consider me as true gardener for this topic but terrace gardening has its own challenges.
Lack of sufficient light:
This challenge has cropped up recently because of tall buildings coming up in the immediate neighborhood. Earlier the light was restricted for a couple of hours to some area of the terrace because of a big water storage tank constructed on the terrace but was not a very serious problem. With the tall buildings light in the earlier part of the day and in the evenings is restricted and affects some plants. The solution is to rotate the position of affected container plants by shifting them to get better sunshine.
Neighboring plants encroaching on your gardens?
The tall trees in the neighborhood although not encroaching on my garden their leaves and sometimes fruit fall on my terrace and cleaning them becomes additional work.
Lifting heavy material
One serious problem for my terrace garden is carrying heavy material like soil, containers, bricks etc all the way up as the building does not have a lift(Elevator). To reach the terrace one has to climb 84 steps!
I have partly solved this problem by attaching a pulley to one of the frames of the covered part of the terrace. With this I can pull weight up to 8 Kg by means of a strong rope with a hook attached at the end.
Arthritis of the hand:
This is not a serious problem at present even at the age of nearing 78 in January 2013 and that is because of being health conscious regarding proper eating habits, regular exercise and sufficient rest. Practice of breathing techniques called pranayam is the secret of good health. I had planned to introduce this science of breathing to all who gathered on the big event at Debbie’s house but I could not attend. It is still on my agenda and hope in the next get-together I will be permitted to do it.
Terrace gardening otherwise is a very enjoyable pass time.
