Arlene, many thanks for your advice and for the very kind words! Hugs to you and your husband! He's so sweet!
I know my English is far from being perfect but I'm happy I can communicate with you all beautiful people on here!
Becky, many thanks to you too!
I don't have any spading fork. And the other problem is that the beds (not real beds, they are like rectangular "pools" filled with soil) are long but really narrow. I have less than 10 inches and it's difficult to use some kind of good tool in there! And they are crowded by (correct?) daylilies! I know it will be a pain
