Hi all. I want to plant daff bulbs so they'll give a good show and will be ok for a few years so I don't have to move them every year. Depth I'm fine with; however, every site you go to gives a different distance to plant apart - anything from "2 bulb widths apart" to 4"-8", with the RHS site weirdly not even giving a distance!
I understand that bulbs are different sizes depending on cultivar and will vary in size throughout their lives, which presumably largely accounts for the range and the wide variety of ranges given.
I also suspect it's ranges partly because, unlike seeds or plants, bulbs are more 3-dimensional, so when I plant sunflowers I plant so each stem's 30cm away from the next, but I guess this isn't the same case with bulbs where the distance given will be between the bulbs, not the stems?
So, how far apart do I plant them? If I assume they'll all eventually get to a height to tip of 6cm and a diameter of 4cm (no idea what they are unfortunately - inherited from my Dad), does that help?!
Yours in confusion! Rob
