Hi Ben,
Watering is a bit "finger-in-the-wind" and 8545 doesn't really help in the 
way which you have started the ball rolling.  It depends upon soil type and 
whether drainage aids/equipment had been incorporated at the time of 
planting. 
Section 11.3 in 8545 suggests testing, but more realistically does provide a 
suggested  benchmark for what is "dry" weather in terms of temperature and 
time elapsed. Annex G. G2 and Table G1 go into more detail, but who in all 
honesty is going to define the soil types in the manner described? - 
particularly as the first year's growth is likely to be in the planting pit, 
which may or may not have used the site's soil, but almost certainly will be 
at a different bulk density.
In a landscape setting where there are ground staff around watering can be 
carried out appropriately.   In a development site . . . ?  or highway 
planting . . . ?
As with all BSIs where there are scant empirical yardsticks, the first 
paragraph in the Foreword under the heading 'Use of this document' applies.
You have a job on, and thank you for your initiative.
Best,
Jim

Subject: Watering trees during the establishment phase

So recently I read a specification produced by a large and well-respected 
landscape architecture firm that recommended watering semi-mature trees with 
'5 litres of water as and when required'. I set them straight but it made me 
realise that there isn't much clear guidance out there.

I'm now putting together my own guide and have come up with the attached 
table. I would be interested to hear what others think about what I'm 
suggesting. Any comments would be welcome, on or off forum.

Also, I'd be very grateful if anyone was willing to share their irrigation 
specifications with me so that I can hopefully produce a practical guide.

Thanks in advance,

Ben
