Q.3 pines trees were ripped out of ground by the roots this winter..
what kind of dirt/loom should I fill the huge holes with, that later if I decide to plant more trees will be good to plant in?
thank you

Are you planning on planting more pine trees? As a rule, pine trees like rich, well draining soil that's a little bit acidic. You can achieve this by mixing regular garden soil with compost (for nutrients and good drainage). There are a few ways to lower the pH of soil, but first conduct a soil test to see if you even need to. Pine needles are very acidic, so incorporating some into the soil should help with both drainage and pH.
