Hi, never been a great fan of tulips, but colour was needed as the daffs began to fade, so, i bit the bullet and 36 bulbs found a new home, planted in november 6in deep with a little compost and well watered in i thought see you in the spring. Well, all have become fully flowered, and in the colour chosen, the problem is all but 2 are bent over double with their heads resting gently on the soil,??? No pest damage, no virus, could it be just saturated heads with all this rain, any ideas, thanks
