Hi Derek - welcome to the forum - we're friendly here
For the Clematis I'd use Fish, Blood & Bone or similar in early spring - Feb here in the UK.
Bulbs and corms contain all the nutrition they need in order to flower so they don't need feeding now. However, after they've flowered it's a good idea to apply a similar fertilizer to encourage the growth of plenty of foliage which will then feed the bulbs for the following season.
