I am so glad I am not the only on with weird tulip results. Some of my pots did nothing at all, some half the tulips grew - literally half, one side or the other, a couple grew well, some leaves only. All were new bulbs bought from a reputable grower - so what is it with tulips this year? At present some of mine are tall and lovely with fat buds which are going to rot away soon without opening if the rain continues. This is one of the reasons I stopped growing parrot and other frilly tulips, they invariably rotted before opening.
In previous years I have had lots of glorious tulips in pots, lovely colours, doing well - is this because of a change in compost? I do wonder when I look at what comes out of bags this year, maybe last years bulb stuff was not good? The mix to get a few but have always left enough for a good show, but not this year - or come to that, last year either.
