Wisteria leaf discoloured
Hi my bonsai fellows!
In need of your advice!
My lovely wisteria has strange coloured leaves and I don’t know what’s wrong? Can someone please help me and tell me what’s wrong and what should I be doing?

Re: Wisteria leaf discoloured
Has it been hot where you are? Mine melted a bit when it was 46 here in Adelaide and looked similar but on a bigger scale. I cut the affected leaves off and new ones grew back in no time

Re: Wisteria leaf discoloured
I’m not worried about the burnt leaves but the discolouration, those are new leaves

Re: Wisteria leaf discoloured
What have you been feeding your wisteria.
Yellow leaves are often a sign of nutrient deficiency. Iron or potassium deficiency can affect younger leaves and cause yellowing, often with the veins remaining green. Nitrogen deficiency usually affects older leaves first with N being moved to the newer leaves to keep them healthy.

Re: Wisteria leaf discoloured
I have been slack and not really fed much this year, I used the slow release fertiliser granules at repotting time last spring and I thought that would be enough... but clearly not... can I fix it now using liquid fertiliser once a week or what else should I do? Will the leaves recover?

Re: Wisteria leaf discoloured
Yes, fertilise ASAP. Liquid fertiliser is usually quite fast acting so if nutrient deficiency is the problem you should start to see an improvement in a week or so. Use something with trace elements if possible ( most commercial ferts have a good range of micronutrients). In most cases the existing leaves should be able to take up the nutrients and should turn green.

Re: Wisteria leaf discoloured
A few of mine did this this year, did some heavy fertilising and moved them out of the really hot sun and they have all bounced back very quickly

Re: Wisteria leaf discoloured
One problem with wisteria is rapid root growth. I find my pots stacked full of roots after a single growing season. Watering becomes difficult when root bound so some sit wisteria in water tray over summer. I try to repot every year or 2.
They are also gross feeders so appreciate plenty of nutrients. Try 'flowering' fertiliser from now to leaf drop to encourage flowers in spring.

Re: Wisteria leaf discoloured
If it is indeed a nutrient deficiency then i would be inclined to think most likely an Iron deficiency from the photo, and possibly manganese at an outside.
What are you using to fertilise? For iron specifically use iron sulphate, but a general foliar feed coupled with a liquid feed would be an easy way to cover off a few options. If it is a manganese deficiency then use mangnesium sulphate.
I'd be inclined to try the foliar feed and liquid feed first, or look for a broad spectrum fertiliser that includes both the iron sulphate and magnesium sulphate.

Re: Wisteria leaf discoloured
Hello Pureheart,
Check your soil pH, then look at one of these tables attached below.
If your soil pH is abnormal, no matter how many macro or micro nutrients you add they will be unavailable to your plants.
Good luck,
Kevin

Re: Wisteria leaf discoloured
Try applying iron chelate supplement to your wisteria. It's used mainly for citrus trees but might help your wisteria.

Re: Wisteria leaf discoloured
Thank you all, I previously used nitrosol and powerfeed.
I found a fertiliser in the garage with iron in it ( can’t remember the name) and sprayed the leaves last weekend... finger crossed it is enough otherwise I’ll purchase what you guys have recommended...
