Posted by Hamza on Tuesday, January 13, 2009 10:50 am AST1. In karachi, the temperature usually remains above 20 C, apart from going down in the winters. The question is that, if temperature remains so high, then shouldn't annual flowers bloom throughout the year? Why is it Marigolds are planted here in December, and Zinnia in the summer? Why different "seasons" when the temperature remains high? 2. Regarding air-layering, books and websites suggest the use of "sphagnum moss", "perilite" and/or "vermiculite". These are not available in Pakistan, and if they are, then really uncommon. What should i use as an alternative? 3. I have kept many plants in my balcony. The problem is, dont know why, but the balcony does not get ANY sunlite in the winter months. What should i do? 4. I have just sown seeds of Aster, Sweet Sultan and Dahlia ie on 9th January. Am i too late for the "season"? I would like to know the names of above plants in urdu as well. 5. Celosia, Tithonia and Cocks comb seeds are very tiny and im having difficulty germinating them. I have tried surface sowing (with light) and shade sowing as well but no luck. I have used around 30-50 seeds avg each. Any advice? 6. Lastly, I have planted a couple plants of "desi gulab" (rose), the one with the fragrance. Given that the temperature remains high, should the rose not bloom all year? Why only winter? We do not have any "frost dates" or anything of the sort. I know i have asked a lot of questions but Will be wainting impatiently for your reply, thanks a million! -hamza
