Spruces and Larch I water 2x per day along with deciduous of its above 85F. Pines are usually Ok to water 1x or even every other day spending if it’s not above 85z sometimes I water the containers too to cool down , some mornings there are a lot of morning mist which keeps the soil moist. Shade net holds spruce , beech , hornbeam of above 85F, along w accent plants. White t shirts go on larches , pines and spruce if still in black containers used to hold collected trees. I feel like 85F is my upper limit for increased watering and shade protection, other than that I water in evening, morning sun w dappled shade until 8 -9 and by 4, everything is shaded by the house. Stuff in shade net gets nothing sun until 11 am ..
