Hi Kathy,
Many thanks for your response. I didn't source the seed from a different supplier but I did source the coir jiffys from a different supplier. Apart from that, seedlings grown in the same way and same place as previous years, same light etc. Perhaps too much overhead watering as well. I'll be more careful.

Hi, Carolyn,
Did you source your seed from a different supplier last year? Any difference in light supply to the seedlings? Lower light is the main cause of stretched out, leggy seedlings. The brown marks could be a fungal leaf spot, either from a bad seed source or overwintered in a greenhouse or in compost.

Hi Carolyn,
If there are any raised bumps where the rust is then it might be Oak Leaf Blister. If no raised bumps then its just a spot rust. Either way its fungal. As the sapling is young I would advocate treating it with a proprietary fungicide to get rid of the infection once and for all. Rake up and burn any leaves - don't compost them.
kind regards,
Ash

Is this some sort of rust on my oak sapling??
Your advice would be appreciated. It was grown from an acorn and is now about 5ft and is in an exceptionally large pot presently - I know it would be better off in the ground.

Is someone able to advise please - the zinnias I grew last year from seed, in coir jiffys were leggy with brown blotches on the leaves. Very different to previous years. Please see pics attached for comparison Is someone able to tell me why the brown marks have occurred before I start sowing again soon. Thank you!!

Hello, Kathy... Thank you for your reply; I found it quite helpful. I did move Murraya to a more sheltered spot outdoors so it wouldn't get too cold. Great advice, especially for a struggling plant. Also, I used a very safe gentle aphid eradicator, with pyrethrins, and was very patient. Friends said: "throw that leafless thing away... but I was patient, and am happy to report a new lush and bug-free growth! Your reminder that Murraya is tender is heeded!

Hi, Chris,
It sounds like aphids (though strange to have them if this plant is indoors). Aphids secrete a substance called honeydew - a sticky solution that once it drops on the plant's leaves, can encourage the growth of sooty mould - most likely the black spots you see. Too things are probably causing the leaves to droop. First, the abrupt change from inside to cool, night conditions will shock the plant. When moving an indoor plant outside, it needs to be acclimated slowly. Since Murraya is tender, it might not like the colder temps, especially at night. Second, the spray might have been too strong. Sometimes, you can remove many aphids by spraying them off with a hosepipe. Is it still outside? Any chance it is getting to cold?

I noticed black sooty spots on the leaves of my Curry Leaf Tree (Murraya koenigii.) The underside of the leaves has caramel brown tiny bugs. This plant was inside and I never saw such a pest on any other of my plants. I immediately took it outside for cooler night air, sprayed it with a spray pyrethrin solution, and waited. The leaves now appear to be dropping off, but I don't notice any new top growth, despite watering and fertilizing. Did this pest kill this plant? It has been two weeks or more.How long should I wait until new healthy growth appears? The photo is one similar to my plant in its healthy stage, for identification purposes.
