Feeding with ericaceous plant food

Would the following plants benefit from ericaceous plant food :
Ferns
Geraniums
Fuscias
Cordaline
Clematus (Nelly Moses)
Begonias (tuber)
Petunias, pansies
Any comments would be appreciated, the begonias certainly need some help.

 

Cannot help with most of them, do not grow them, but clematis like a slightly alkaline soil rather than acid so they certainly would not need ericaceous feed.
With ferns it depends on the kind, some are from acid woodland and some from lime rich soils.

 

I've grown most of those at some time and I think with the possible exeption of SOME ferns, all will grow quite happily in ordinary compost with ordinary feed.
Cordyline can become very quickly starved in containers, I find, so tend to go yellowish, but more of a nitrogen problem I would think.

 

Pete is right I think- I've not grown cordylines, but have tried the others.
Begonias are more particular about type of soil than acidity, they like well-drained soil and rot if in soggy conditions. Add something like pearlite to their growing mixture.

 

I have begonia pendula's in a large 1 1.2 ft tub, i found that they grew very well in a sunny position in ordinary compost as long as they weren't over watered. Once the leaves sprouted they needed watering liberally. The red ones always seem to flower first, followed by the pink. I am still waiting on the orangey coloured ones.......... I did give them some normal feed once they had started to sprout decently, but not fed again, they are doing well on their own.

I forgot to say also that I have an australian bottle brush which likes erichaceous feed, i planted black leaf geraniums each side once the red brushes had done their thingand they are doing fine. I give iron feed to my rhodedendron, azalia, bottle brush & camelia but don't know if the others on your list would benefit from it.

I also have a cordyline which i grow in a large pot, it is now 6 years old and benefits from just plain waterin g. I generally leave it be unless it needs stripping.

Toodle pip,
