Paperwhite

These are paperwhite narcissis which I planted before Christmas. They have come up this far and stopped. Two other pots planted around the same time have flowered and gone over.
Any ideas why they have stopped and what I can do to get them to grow and flower, or should I just dispose of them?
Thanks.

 

Do you mean you bought them as new bulbs or they were from your own stock ? Were those that flowered planted in a similar ceramic pot ? They look quite healthy but without seeing the actual bulbs, it's difficult to gauge whether they are of full flowering size or not or whether the roots are viable. I'd be tempted to take them out and check each one before you get rid of them

 

@Philippa I bought them as new bulbs. I can't honestly remember what the others were planted in but they were all planted at roughly the same time.

 

Does the container have a drainage hole @katecat58? If so, and you used the same compost, try moving the container to the same location where the other ones flowered. It could be a slight change in heat, light or water that they need.

 

It doesn't have a drainage hole @Plantminded, they came in a set together, but they are not waterlogged. They were all very close together on my kitchen windowsill. I brought this one in the dining room as it's warmer in here. The shoots feel strong and sturdy, not limp, they are just not getting any taller.

 

I seem to recall reading something many years ago about not planting in pots which are "glazed" on the interior . To do with the roots not wanting to live against the smooth sides and therefore not expanding. It would have been in a gardening book or magazine but I can't remember any more than that. Sorry @katecat58

 

I wonder if that is it @Philippa. Thanks to you and @Plantminded. I think they can go on the compost heap.
