Strelizia Regina - Bird of Paradise - no top growth - Help please

I bought a small strelizia about four years ago.  It only seems able to produce three leaves, dropping one if it produces a new one.  It is in a large pot - kept indoors in an unheated lobby
 over winter, and goes outside in the summer.  Today I have emptied the entire pot out to see if there were any of those nasty little white grubs.  I was surprised to find a mass of fat well grown roots but no sign of grubs.  What to do now?  Obviously feeding it has caused massive root growth so should I just re-pot and starve it?  Water it just a little bit, or give it a good soak?  Change the type of compost to something more barren and gritty?
Any help welcome right now 'cos clearly I'm not doing it right at the moment.

    Hello gg
    Your Strelitzia reginae sounds like it's struggling a bit ;I can't see a picture so I'm guessing the plant is still fairly small but in a large pot? Root growth has probably been stimulated as you say by feeding .Try re-potting into a loamy but free-draining soil ; water once a week when we eventually get some warmer weather ,and if possible place near a sunny south-facing wall .Leave the feeding for a while .
    They need maximum sunshine and minimum temperature of around 10 C .

    Very little water during winter , otherwise sappy and weak growth will result .

    I have a massive Aloe marlothii which stands out all summer , rarely gets watered and relies on rainfall ; your plant can stand similar conditions ; to quote an old adage , "you can kill them with kindness" ; hope I've helped in some way ; good luck !
  • I've put it's huge root system back in the pot and covered it with a mixture of rose and shrub compost and multi-purpose with a generous  addition of grit.  I'll give it a light watering in the morning and then pop it in the greenhouse for a few days before siting it outside for the summer.  Leaves are substantial, but only three.  I think it will benefit from a bit of neglect!
    Thanks for your helpful advice.

    One point to remember though ; it's going to get much warmer and brighter this week, so don't 'bleach' your plant by exposing it to sudden (and rare) sunlight ; acclimatise gradually !
    Hope it's allright !
  • Many thanks - we'll just have to see what happens, otherwise I'll have to give
     it a bit of a talking to!
