Last week I happened to notice a magazine with the heading “Why won’t my wisteria flower?” Well, if you are like me who has had an unforgiving wisteria for years, which just wouldn’t part with a single flower, you will be drawn to the buy the magazine just as a bee is drawn to the pollen on a flower. The magazine I picked up was Gardener’s World and the article was written by Alan Titchmarsh to read it click here.
Weak wisteria flowers, shown above, I was finally rewarded with two years ago – after approx 8-9 years of patience! I have to say despite them being rather pathetic specimens I was absolutely thrilled to get them. I had given up all hope. My wisteria is the variety sinensis ‘Alba’ – a white fragrant one. The flowers last year were not much better in quality either – I didn’t even bother taking photos.
The article in the magazine suggests considering the location (ok), pruning twice a year (done) but it also suggest something I haven’t done. It suggests a feed with a high potash-rich fertiliser, such as a specialist rose fertilizer. I plan to get some from my local garden centre tomorrow. I am late with this feed. Alan suggests in his article that February is the time to give it – but better late than not at all! It is definitely worth a try, extra watering too. If this year is hot and dry some extra pampering perhaps won’t go amiss.

The photograph, shown above, was taken in my garden on June 4th 2005.
