Hi, I just found this forum.
I have a Nectarine plant that I grew from a seed. It is in ordinary garden compost and grew after a few months. It got to about 10 centimetres long and stopped growing. After a while of staying still, it has started turning patchy yellow and brown, and the leaves are curling.
Some have dropped off. There also seems to be a spider web forming on the top of it.
Anyone know what is wrong with it and how I can save it?

Okay, thanks. What can I do about a fungal disease? I did plant other seeds, but they have not grown.opabinia51 wrote:Sounds like it is done, it may have succomb to a fungal disease.
In the future, try planting several seeds just to increase the chances of a sapling surviving.
In nature, it is very rare for all offspring to survive.

Well, it just might be a fungal disease. It could have been overwatered (which could easily lead to some sort of disease) or the seedling could have been underwatered and just died from dessication.
But, just reading your description, I'm thinking that it may have been a fungal disease.
Anyway, to avoid disease just try to have a well balanced soil with insoluble nutrients in the form of compost, insects and the like. Do not use any chemical with the suffix "Cide" in it because these compounds break down soil structure and kill both pathogenic and beneficial soil biota often breading incredibly resistant pathogens through artificial selection.
There are a lot of threads in the Organic Forum on how to create healthy soil so, I'll let you read those.
Another option would be to try to start the seeds in small pots in unsterilized potting soil mixed with compost and bit of manure. This will rule out the "Competition Factor" that seeds grown in straight soil have to deal with.

Hi Sweyn,
The webbing and yellowing of leaves makes me think of spider mites. You might want to take a piece of paper and hold it below the web. Tap the plant and see if you get any that drop onto the paper. Insecticidal soap will work on those and you can make your own. Don't use detergent. You will need to spray several times. Spider mites tend to attack stressed plants so look to see what needs imroving Citrus likes to dry out a bit between watering. Take a look at these sites for some help.

Tangerines are often called Mandarins. Take a look at this site as you might be able to id which variety you have. There's even one that grows better in the desert.
