Hi I have a three year old nectarine tree this is the first year the fruit has stayed on the tree.The fruit is green but is starting to shrivel we dont know if this is from the heat or the tiny black ants we found in the seed pod when we opened one up has any body got any ideas.I am learning as i have not had much to do with growing fruit. Thankyou.

Hi John Thankyou for your advice.The fruit started falling off so I have picked it all,they are egg size,soft ones taste ok,skin is like leather.I thought if we pruned it a bit harch the roots may establish more,we do water it every night,what fertiliser would you recomend,I have been using a fruit tree fertiliser maybe it needs more. Thanks allot Marilyn.

What you did is the same as my neighbor. The tree would probably have now grown large branches all over the place. This autumn reprune the tree not so harse. You need to do this for the next 2 years to regain the shape you want back. As for the roots, they sound ok but try some seasol (seaweed extract). As for fertizer a complete D with an adition of 10% potast will make a complete fertilizer for you. By the way egg size fruit is not bad, mine were from that to a duck and becuase of my conditions here my trees take an extra 2 years to fruit.

Pardon my ignorance, but what is a 'complete D'?

complete D fertizer. its manufactered, but when mixed with about 10% pot ash makes a very good and cheap alround fertilizer that can be used on almost any plant.

We have lots of ash from our wood burning stove, is it good fertilizer for all types of fruit trees, if not which ones do not like it.

Wood ash will probably effect pH as it is alkaline.

Hi, there is an orange mushroom growing on the trunk of my nectarine tree. Is this bad? What can i do to help the tree? Or do I have to cut the entire tree down? I've got an apricot tree right next to it - will the problem spread to my apricot tree?
Thanks and Regards.

HI All,
Something is eating the skin off all my immature nectarines. It doesn't appear to be ants and I can't find any bugs on the tree. Anyone know what it might be?

Thanks Ellen, but there are no signs of slugs. Given that almost every piece of fruit on the tree has been damaged (its a dwarf nectarine) I would have thought I would find at least one culprit. The only bugs I can see are a few ants and they don't seem interested in the fruit.

Hi John 1, slugs hide in things and under the soil during the day,have you tried going out with a torch at night? Multigard has petsafe slug and snail pellets ( the active ingredient is iron). Sometimes earwigs chew on things if there are a lot of them. How big is your tree ? Some fruit I protect with little bags I make from old net curtains from the op shop (one mans trash is another mans treasure etc etc).

Hi Jantina,
I would have thought that slugs would have left a slimy path where they have been (particularly on the fruit itself). There is no indication of this. We do get a lot of earwigs but I've found no signs of them either. I thought maybe thrip but the damage is more extensive than the sample pictures I've seen of thrip damage.

My dwarf nectarine has very similar damage. I thought it was because the tree also has leaf curl.
I think it is slug damage - we have been going on slug patrol each night and the first night we found approx. 200 slugs, the next about 100 and then considerably less after this.
The slime marks left by the slugs are a bit hard to see as the slugs are actually quite small.
I suggest slug hunting at night with a torch and using the Multigard slug pellets.
This years 'crop' is a write off but hope to get something next year.
Good luck !

Thanks Tiggerbow (and Jantina),
The consensus seems to be slugs. It's definitely not because of leaf curl, I managed to spray in time to prevent leaf curl. I think my crop this year is also a write off, but if I can confirm the problem then I have a chance to prevent it next year.

John, I think you may have caterpillar damage. I have the same problem - immature fruit with skin eaten off. Your picture is exactly the same as my damage. I looked on the underside of leaves in the area and found one caterpillar - I think it is a looper variety as it has legs only at the top and bottom, therefore loops when it moves. I can actually see the path the caterpillar has taken on my baby nectarines. It is hard to pick, but if you have a freshly eaten one you can easily see the eating lines. In older ones the flesh dries a bit and maybe starts to look like dry scab damage. My caterpillar is blue with yellow stripes. They are hard to spot and when you remove them they spray a silky thread which is quite strong. Happy hunting!

Thanks Jacquelynn,
You could be right. I removed all the damaged fruit (about 80% of the crop) and I put out slug pellets (and a beer trap) but this hasn't worked. I'll take a close look for caterpillar tomorrow.

Ok, I finally discovered the cause... earwigs... hundreds of the little pests. Anyone have a good (organic) earwig remedy?

I've never seen earwigs, but I believe they like to hide in damp, dark places. You can trap them by making hiding places from rolled up cardboard, or almost anything that will roll up.

Empty them and destroy next day. Or feed to the chooks, if you have any.

Earwigs are evil - I used to think they were cute until I started gardening. They eat all my seedlings. Here were some ideas I found on the net (have yet to implement them). I tried pyrethrum spray, but it didn't make much diff.

There are a couple of ideas on this page:

No probs, hope it helps. I have started saving my tin cans so I can put some earwig enticing liquids in them. Awful problem.
