I live in Pakistan and am a great fan of flower gardening. This year I imported plug plants of primula, begonia, and calibrachoa from UK and tried my level best to protect them from the extreme heat of Pakistan; unfortunately none survived although I provided them with ideal controlled temperature in a glassed refrigerator and under grow lights.
Could you suggest some measures to protect them? My local primula are thriving in the refrigerator and have come to flowering, therefore it is strange for me as to why imported ones have not survived. Then I have planted geraniums in Jiffy's; they are growing very fast, but I suspect that they might wilt; the only cause that seems to me is excessive heat around 90 F. Kindly give me some advice.
I would suggest trying to grow them underground in a basement or other area because I do not know how else to protect them from the awful heat. As well, they might need specific nutrients that your soil is just not providing.
Certain plants are suited for certain areas. Never buy or try to grow anything that is not for your area. In my area, I can't grow any fruits that need 90 days of very hot weather.
Check out these photos.
I purchased it two summers ago, and it half-heartedly bloomed. I decided to look through the dirt inside the flower pot last spring, and found her dried-up little tuber. On a hunch, I placed it in a new flower pot with quality soil back outside, watered her when dry.
This yellow Non-Stop Begonia is beautiful and has been blooming constantly.
