You could dig up the non-flowerers (now is fine, leave the leaves on)
gently tease the bulbs apart and replant them more spread out in a
different place. There should be 5" of soil above the top of the bulb
(don't worry about the leaves being deeper than before.). Scatter some
growmore on the soil surface. It may take them a couple of years to
build up enough strenth to start flowering again.


If you lift the daffs now and replant then they won't make any new roots
this season so putting growmore on the soil will do nothing for them.
I'd rather give them a watering with Tomato feed and leave the lifting
till the leaves have yellowed, that way they will have at least had some
sort of chance to put some feed into the bulbs.

If you really want yellow daffs then then lift the existing ones and
replant them elsewhere and plant new yellow ones in the late summer, the
earlier you can plant the better.

That sounds like a plan. Thanks.
