名媛直播

Hi everyone,

I live in Sydney, Australia. We are in summer at the moment. I was advised to water my Wisteria 名媛直播 8 cups a day in summer and the past few years it has been fine. Last week I saw my leaves turning yellow. I thought maybe I’ve over watered the bonsai. So I stopped for 2 days , and watered it again. I took off the yellow leaves and today and went to water it again and even more leaves have turned yellow!! Please help, am I over watering or not enough? It’s near my front door. There is a shelter over it but sun does go on it all day. I’ve had my leaves sun burn before so I don’t think it’s due to sun unless it’s just too much heat?

Any help is appreciated!!

HI, welcome to the empire.

Good of you to notice that watering by measuring and om a timer is not the way to go about it. You normally water when the soil is just starting to get ry. For some species a little before. OF other species, a little later.

Do you know the species of plant you bought? To be hones, at the moment I cannot tell. It could be a wisteria, but you being on the other side of the gloeb leaves a lot of wiggle room when it omes to species.

THe pot you have it in.. Does it drain ?

Hi there,

Thanks for your reply. Yes it is actually A Wisteria! I do have a drainage in the pot.

Maybe I will start to touch the soil and water it when it gets dry.

The last few years I watered it the same amount and always Was fine. The only difference is I always have taken it out of the sun after 5 hours and placed it in the shade every day. But this time I’m unable to do that so it’s in the heat the whole day and I keep watering it

As a tree gets bigger, it demands more water. A tree in full sun demands more water than a tree in shade.

As you have allready figured out. Water according to demand. Not according to directions.

So it might be a shortage of water. Wisteria loves water in summer. So now you have summer and it is hot.. Just put it in a tray of water. As long as it drinks all water in the tray on a daily basis you are fine.

Wisteria loves water. In summer like leatherback said, i also put a dish with water underneat it.
I have also seen people putting there wisteria in pot, in there fishpond for the summer.

The yellowing on the leafs, if i see it right, are the lower leafs of the plant. Following a deficienty chart, and how they yellow. It might be manganese sortage. Does not look like sunburn.
Do you firtilize the wisteria? NPK only , or with all trace/micro nutritions?
And what is the PH of the soil? PH should be between 6 and 7. Higher or lower could prevent nutritions pickup by the roots. Do you water with rainwater, or hard tap water?

I dont Think it is nutrition deficiency. However, if it is, nitrogen is by far the Most common deficiency when older leaves get yelow. Managanese is less likelky.

You could be right Tropfrog, I tought Wisteria was a low nitrogen plant, gets most of its nitrogen from the air. And adding extra nitrogen will give a lot new green growth, but that can result in less flowers, or no flowers at all.

Point taken and lesson learned.

This chart came to from the head gardener at a local estate. He uses it and it diagnosed some problems for me, apparently correctly because the trees are all alive.

YMMV
