Garden Q&A: Why hasn't my magnolia tree flowered? 

Whether you're a gardening beginner or expert, Irish Examiner columnist Peter Dowdall has the answer to your questions

I hope you can help: I have a mature, 15ft magnolia tree. I planted it two years ago, but it hasn’t flowered, has very few leaves, and looks quite sickly.  Is it advisable to feed it and if so, what do you recommend?
