Junipers are indistructible... one of my mame precumbens nana's once got knocked of my bench by the wind, fell out of it's plastic training pot and lay there with naked roots on red painted pavement in the african sun(middle of summer, was way more than 100f) for more than 5 hours, long story short: I still have it and its still alive and kicking...

White pines... you will have to hear specifics from either Owen, Adair or John Kirby.

I give all my trees chemical fertilizer - I don't have anywhere to make/mix all the custom organic cakes that many others use (maybe one day). So I just use a balanced fert - it's 20-20-20 (it comes in a big tub of powder and you mix in a watering can http://www.homedepot.ca/product/all-purpose-fertilizer-20-20-20-1-kg/917264). I start that when the pots are no longer frozen solid and I have to actually start watering my trees - which is around now in Calgary (zone 3a/b). I use this bi-weekly and do it about double strength.

I also have slow release granules that are formulated for trees and shrubs - I can't find a link and don't remember what the NPK breakdown is, but I lightly sprinkle them on the soil surface once a month or maybe every 3 weeks, to top up in between the bi-weekly fertilizer I use.

I do this for all my trees, but just to emphasize why they get fertilized what seems like a lot - they are all in non-organic soil, so they don't get any nutrients from the soil components. So they have to get it all from the fertilizer.

This is just what I do, and I am pretty new at this.

I did read that specifically for pines you should stop fertilizing when you see the candles extending - this will keep the new growth from getting too leggy and keep it compact. As soon as the growth has hardened off then you can start fertilizing again. So for pines - fertilize in early spring then stop, and then start again late summer and fert through the fall. I could be wrong on this though when it comes to white pines vs black pines - they may be treated differently.
