cross pollination of apple trees

Posted: 30/07/2014 at 13:02

Hi marion, what you describe is not possible - cross pollination only affects the seeds and cannot change the variety of an existing tree.  What can happen is that branches can grow from below the graft point (virtually all apple trees have the named variety grafted onto a different rootstock.)  If branches are allowed to grow from below the graft, they will produce apples of the rootstock variety.  As rootstocks are chosen for their vigour and not fruit, these branches will usually take over and become dominant.  Have a look to see if you can find the original graft union and remove any branches which come from below that point.

Mildew can also badly affect a tree enough to change the quality of the fruit.  It is difficult to deal with but generally is due to dryness at the roots and high humidity in the air.  You can do little about the humidity, but giving the trees a regular and deep watering should help with the dryness.  My advice would be to keep a circle of ground, about a metre in diameter around the base of the trunks, clear of grass, weeds and other plants.  After watering them well, mulch this area with a good layer of garden compost mixed with well rotted farmyard manure from a garden centre.  Top the layer up each Spring.  Also make sure you are pruning the trees properly so that their is plenty of light and air getting into the centre and ensure the trees are not being overly shaded by surrounding trees and large shrubs.

Have a very close look at the back of the affected leaves and check for tiny caterpillars.  I have them on mine (last year too) and they eat all of the green matter from below, leaving only the upper surface and veins. The leaves then dry and go crispy.  No-one seems sure of exactly which moth or sawfly is causing this - it may be an invader from the US and affects carrots, too.  I had to spray with an organic bug spray as the rate at which the damage spread was incredible.  There are threads about it on other forums:

Whereabouts (roughly) do you live Johanna?  Most of the things I've read about Feijoa say the fruit only has a chance of maturing in the south of the UK, so if you are elsewhere I'd be tempted to leave it and just enjoy the flowers.  Being an evergreen means it might be risky to move it, but the time I'd attempt that would be in the Autumn.

A request or suggestion.

Mike, click the little green arrow on the right hand side of a thread in the list and it will take you to the last page on that thread.  The latest post will be at the bottom, so you may need to scroll down.

All my gages have gone!

My money would still be on squirrels - they are after the kernel in the stone and won't be interested in the flesh, so ripeness is not a factor in their choice.  Their modus operandi is to collect and hoard food for the winter, so there are probably several 'larders' of gages buried nearby.  Just one squirrel took every single hazelnut from my tree in just 24h the Autumn before last;  They are extremely industrious once they set their mind to a task, the little b*ggers!

They are also edible and have a slight peppery taste - nice addition to a salad.

Or being grown in a position without enough sun or shelter - they are a tropical plant after all.

You only missed them by a couple of weeks LL - they're generally available up until about mid-July.

Now would be ok if you can find plants as it's too late to grow them from seed - they do most of their growing at the same time as normal cabbages, but are resilient enough to survive through the winter.  If you manage to find some young plants, plant them deep, up to their bottom leaves, firm the ground well around the stem and keep them well watered otherwise they might bolt in this warm weather.

You're lucky to keep it alive Johanna - I've failed miserably to grow one from seed - they have always died on me over the first winter!

I think it will need a very sheltered position in full sun to fruit outside in the UK - against a south-facing wall would likely be your best bet.  I think they do well in conservatories.
