I would have put this on the old general gardening thread but can't find it.
Short version - high level very exposed balcony, planted various troughs. Snowdrops - planted 42. In fairness I was warned these were hard to grow. Now only 3 coming up. Won't be trying that again!!
however, my question is about something else - hopefully not a hugely stupid question. I planted a mixed trough with various tulips - standard dwarf and ranculus I think they were called. Their shoots are coming up but accompanied by quite a lot of greenery.
My question is, given they are planted closely in a small trough - so not a lot nourishment - are these green leafy bits (quite long) necessary or just a pretty extra will take up nourishment that the bulbs need? I've never seen tulips surrounded by this narrow leafy greenery, they are not growing around the bulbs, but just randomly. As it's mixed trough, does their appearance signify busy bulbs below the surface?
Like lots of bulbs, tulips will produce leaves before they produce flowers. Because the leaves basically are a power plant for the plant, adding to the energy store in the bulb itself, it's important not to cut them off!
I'm surprised that you describe them as narrow though - tulip leaves are sort of sword shaped and broad. It couldn't be weeds that have got into the pot could it? The other thing that is strange is that this time of year, tulip leaves are usually quite small, though it may be that your balcony is providing them with warmth and shelter so they will flower a bit earlier. Can you post a picture?
If they are definitely weeds, you should be able to get them out without disturbing the tulips too much - chances are they will be more shallowly rooted. It sounds almost like some kind of grass sprouting in there?
One other thought - you couldn't have put in another load of bulbs that you've forgotten about, could you? I have allium roseum, and the leaves looks a bit like grass when they come through (and they are through now). They're also included in loads of free bulb offers.
