Hi,
We do things a little differently in both the uk and france "Let me explain and then you have a think,
(A) Getting the tree (in this case pear but any tree or long term plants) ready for any sudden weather changes, ie the ground must have both really good drainage (yours looks like a very wet area) and when planting ensure that you've used slow acting feed for the root system,
Did you do this ?
But the thing to think about is not getting caught out by late frost etc a good straw mulch around the base helps not only in very dry weather to keep the soil moist "But more important it also helps keep the root system warmer, and another very good idea is to use fleece wrapped around the fruit tree all the way down to the mulch level to keep wind damage/snow? / and freezing winds from causing damage,
After all these trees are young and all ive mentioned are weak area's to the tree "now" until it get's a good root system strong enough to both hold the tree steady in wind (i use a stake for the first year and if the trees roots have got a good hold then & only then remove the stake)
But yours has nothing !! whats the tree to do should strong winds start to push it side to side ? Any root growth wont hold in the ground and without good roots you'll not have any above ground growth !!!!!! or a healthy tree,
The fleece also helps keep rain off the buds just enough so the tree can not have the marks yours have,
Last but not least, Have a look at the weeds etc all starting to grow around the base of your tree, these are the pathway for insects etc ,
I again keep this area clear of all weeds etc by using old news papers held down by stones etc
at this early planting stage and later keep it clear as it aids feeding the tree and if you like a bit of colour then plant tagets (they sort out a host of insects) or spring flowering bulbs, these will remind you it liquid feeding time if you want to use Liquids ?
A fruit tree such as this pear takes 7 years before its classed as giving full harvest,
As it gets larger you'll need to keep it pruned if you want a good sized pear off the tree, if you neglect to prune you'll get three or four times the harvest "But" very small pears,
"Feeding"
Again i use horse manure and always have this i apply during the months of febuary/march when the roots are wakening up and getting ready to grow,
The mulch is replaced over the manure until all signs of bad weather has gone end of may /early june. And then the straw is removed,
The fleece,
This is very light and can be removed or replaced with little warning of bed weather, ie if a sudden late frost is forcast or rain rain & more rain then its simple to take action and replace it should you have removed it early and you have leaf growth and dont want the rain to damage the leaf,
Now i know this may seem like a bit of work but most of it is only until the young tree has settled in and rooted well after this stage you'll be looking at spraying etc but this can only be done when your expecting good leaves etc,
Hope this little has given you some room for thought?
Remember if you start off right you'll have fruit for many many years?
Start off wrong and you'll have problems for many years??????
