Wow, thanks for such long but valuable reply, Martina! You seem to be like Nicola Tesla who also projected his future creations in his mind before the actual physical realization :)
And I totally agree with you that in some instances there is a must for trial and error. Like it happened for you in gardening :)
Thank you for your time, Martina and sorry for late response :)
The garden story: In some cases, I could have been smarter. But nature brings a lot of unexpected situations, too. After all, looking back, you know better. My present situation however, confronts me with sheer unsoluble situations again. Gardening Is never a bore! :)
