Hi,

I have 2 Wisteria seedlings that are now about 6 months old. They were growing quite quickly but seem to have stopped over the last few weeks. They've been in the current pots for about 3 months now, could it be time to repot?

More concerning however is the condition of the leaves and pests. I've uploaded a bunch of pictures showing the below.

- Tiny spider like creatures that I get rid of, I'm assuming spiders because I can see tiny webs. Is there a safe insecticide I could use?

- The leaf colour - a little bit yellowly, some brown spots.

- The leaf texture. They're a little bit "crispy"

Generally, I water them every few days when the soil appears to be drying. The pots have good drainage. I keep them in the room next to my conservatory where there is a little bit of light coming through the blinds as the conservatory was getting too hot and causing the leaves to burn up.

Is anyone able to help me figure out what's causing the poor condition and what I can do about the pests?

Thanks!

Yup, spider mites. Do not use insecticide. That is for insects, not spiders/mites. You need to get something specifically against spider mite.

Furthermore.. You canont grow these indoors. The climate is wrong. Move outside. Adjust to sun intensity over a period of 2 weeks and put in full sun.

Thanks for the quick reply. Do you believe the pests to be the cause of the leaf condition or are they just a cosmetic annoyance?

Also, I picked wisteria as this website and several others says they can be grown indoors or outdoors. What would be the main difference growing these out versus in?

The spider mites love too dry environment. They can be treated very efeciently with predatory mites (Phytoseiulus persimilis). Environmental friendly, safe and fun.

I am absolutely sure it's spider mites.
They hate it humid, they love plants inside in the dry environment, I kill them with insecticidal soap.

Tey are the cause.

The main difference would be.. Inside they die. Outside they may live.

quite right, and they need a lot of water too. This web site would not say that Wisteria can be grown inside.

Thanks for the feedback. I've put them outside now. I'll monitor them over the next few days to see if the mites clear up.

FYI I live in the UK. Not the hottest/dryest come October. Any idea why so many places say wisteria can be indoors?

Because they are idiots. If they are selling then hey will say anything to sell them. Wisteria need a lot of water, I have stood mine in water during the hottest part of the summer. I am in England and we have had a hot dry summer apart from a few days when we have had rain.
