    Can anyone tell me how to get more and better blossoms on my plants?
    Last year I had 4 & 5 blossoms on my 2 plants, this year only one blossom apiece.
    I have used high Phosphorus, with no good results.
    Would appreciate any help.
    The plants are very healthy with an abundance of leaves but no blossoms.
    Thank you.

    Too cold in winter? Too much pruning? Sample your soil and have it tested before doing anymore fertilizing. High doses of phosphorus can be detrimental.

    Overwintering flower buds are set at branch ends, cutting back between the time these are set and they open prevents flowering on old wood. Some flowering on new growth may also occur, if you are pruning annually and getting a scattering of small heads later in summer maybe that's why. If you are seeing big flower buds set at branch tips each fall, that do not open in spring (or the branches themselves are actually freezing back) then your winter climate is the problem.

    We had a terrible winter this past year in the Mid-Atlantic. That may be your problem and also DEER?

    Do you think if I try to use some type of cover, over the cold months might help?
    Also maybe I should cut back on the pruninfg, maybe too much?
    Thanks.
