topdressing soil for tsuga canadensis 'jeddeloh'
hi--i have this beauty. it's about 2-3 feet across. we've had a long winter (lots of snow), and i just noticed needles browning at some of the tips of the branches. i am wondering whether our soil is too sweet or whether i should topdress with a soil acidifier. the browning could simply be due to winter burn or snowpack issues, but i guess the soil pH issue may need to be addressed either way.
i haven't ever gotten the soil tested (i know, i know), but our soil in wisconsin is full of lime. i have added lots of organic matter to the soil, but even so i wonder whether this little guy could handle some soil acidification. i remember reading that hemlocks like slightly acidic soil.
do you think the browning could be related to soil pH? if topdressing is recommended, what should i use/how much? any help/suggestions appreciated. thank you! kathy
