I planted a trough of mixed Tulips from a collection from Sarah Raven. I used the lasagna method to layer the different bulb varieties. Well what a disappointment. Two thirds have come up and out of these only half have come into flower. There's a couple with no buds then a couple where the growth seems to have arrested and the stem is short and the bud small, then in a few of these ones the bud looks as if it's going brown and drying. The ones that have come into flower look strong and tall though.
I used to have tulips in here prev (but didn't much like the colour) so I know they do ok in this trough and this particular position in the garden.
Any thoughts. Should I the bulbs again next year?
