Feeding Wisteria

We have had a wisteria for about two years (it was about 4 ft high when we bought it so not really sure how old it is) which comes into leaf very well about May but right now the leaves are turning yellow and then brown and dropping off.  This happened last year as well.  It is planted on a south facing wall but we keep it well watered, What is the best feed for wisterias to promote green leaves and eventually flowers?

    Maybe you are over watering and washing away nutrients.   I would try adding some liquid tomato food to the water.   Next spring, give it a slow release feed of rose or tomato fertiliser granules and an occasional liquid tonic of tomato feed.

    The key to getting a wisteria to flower is correct pruning in July/August and then again Jan/Feb.  There's some useful info and videos here - https://www.rhs.org.uk/advice/profile?pid=242

  • Thank you obelixx - will give the feeding a try.

    Make sure you prune it properly too.   Hope it works as the flowers are lovely and have good perfume too.

  • We had a new patio/paving laid last year and it has gone green in places already. It is a riven Indian Sandstone and we are not sure we should clean it with a power washer in case it breaks away some of the riven edges.  We have tried scrubbing it with a washing up liquid solution as some have suggested but this hasn't removed the green algae.

    We wanted to have the paving sealed last year but the contractor advised against doing it until the spring.  Does anyone have any suggestion as to what would remove the algae successfully, please?image

    There are special algae washes that you can find in good garden centres and DIY stores.   As far as I know, some just clean it off and others can prevent it coming back for a while so you'll have to read the labels.

    Make sure it doesn't splash onto treasures you wish to thrive.

  • Thank you for the ideas - we will try them all and hope one of them works!

    We have the same. We clean it with the pressure washer with the patio attachment, much gentler, doesn't splash dirty water everywhere and cleans very well.
