Codling Moth on 6 old trees

We have 5 old apple trees and one old pear tree, all 10 to 15 feet high. They have always been good croppers and are professionally pruned every 2 years. In recent years, we have developed a huge problem with Codling Moth. We have used the traps each of the past 3 seasons. The first year 50% of the crop were affected. Last year the percentage was much lower, but it was an enormous crop. This year, the apple crop is much smaller, and it looks like a high percentage are affected again. Some pears are always affected. I understand that most garden insect sprays have been banned. I agree with this, but clearly the Pheromone based glue traps are not working. Any suggestions? bindweed, Limerick, Co Limerick Posted: 29/08/2017

The traps only catch some of the male moths and fertilised females can go on laying eggs.

You need to spray at blossom fall and two weeks later with a garden insecticide, organic if you wish, such as pyrethrum. 

 

Apple Tree

! planted a new apple tree ( bare root) early this year. started to leaf and produced two trusses of flowers with 5 flower heads on each. When flowers went the little apple buds appeared. however checked one morning to find one complete truss gone. put a mesh on the other one in case it was birds but next morning two gone with one hanging off, eventually the other two went. what can we do to stop this happening next year as out crop is gone for this year? yvonneodo, Dunboyne, Co Meath Posted: 27/05/2017

Young apple trees usually abort any flowers for a couple of years and then slowly begin cropping as they grow bigger.

Prune old apple tree

Looking for help on pruning this old apple tree. I was pruned a couple of years back back but not sure if it was done right.A lot of new [long] shoots appeared [see pic] some are bearing fruit . Any help would be appreciated 100720161, Tara, Co Meath Posted: 10/09/2016

When an old tree is hard pruned, it grows back stongly and the re-growth needs to be thinned out and some shortened back in JUly August. Do it now for this year.

Start by removing new shoots growing towards the centre and shorten or remove others if crowded.

Repeat this summer pruning each year to keep it under control and winter prune as well.

fungal/pest disease on apple tree

Can you tell if this is a fungal or pest problem on my apple tree.Some leaves are going brown, others have a mosaic pattern on them and there are holes in the apples. Can you give me advice on how to treat this problem? Berns, Dublin, Co Dublin Posted: 30/08/2016

The wool is due to woolly aphid,a form of greenflly. Use a garden insectide when the apples are gone.

Mosaic patterns are due to leaf-miner burrowing, largely harmless.

Holes in fruit is probably codling moth, apply Nemasys in June, from Mr Middleton. This is eelworm-based and there are no chemical residues.

 

Problem with Apple trees

We have 5 apple trees, Bramley, Golden Delicious, Coxs orange Pippin, Braeburn, Floweing Crab. There was a a very good crop of blossoms on each tree, which formed small fruits on the long stems, but progressed no further. All of these fell off the 5 trees. We had a great crop last year. Just wondering if there was any infection this year or what could be the possible reason for the lack of crop. What do we need to do to sort it out for next years crop. louisenoc, Grenagh, Co Cork Posted: 29/08/2016

Apple trees often take rest after a heavy crop, exhausted, and while they flowered, they may not have set seeds, which are necessary for fruit development.

In a heavy year, take off some fruit to reduce the load and improve the quality. Feed with general fertiliser in the good year, not farmyard manure. 

 

Fruit trees on north-facing slope?

Can I grow fruit trees on a north facing slope? I am in West Cork near to the sea. The land is arable and the slope is approx. 45 degrees and drains well. regards Dan O'Leary 300420161, bantry, Co Cork Posted: 30/04/2016


The West, being rainy which encourages disease is a challenge, as is proximity to the sea, because of wind, as is a north-facing site, because of less sunshine. Good drainage is a big positive factor.
 
Apple trees are the best bet.
 
Try 'Lord Lambourne', 'Discovery' and 'Bramley's Seedling', two dessert and one cooking.
 
Control grass for a diameter of 1.5 metres.
