Q: I will be planting blueberries in 18 inch tall 4x8 raised beds. I plan to use this as my basic soil: (pH 6-6.5) 30% Native Screened Sandy Loam 40% Garden Compost 5% Power Mulch 5% Mushroom Compost 20% Horticultural Pumice. How can I transform this basic soil to make it perfect for blueberries? I am thinking of taking the basic soil and combining it with equal parts...
Compost is an acceptable amendment for blueberry plants, but it's important to test it before you apply it. Pay attention to pH and nutrient levels, and watch out for weeds.
Moss will return if underlying reasons for its growth aren't addressed
