Amending soil for blueberries???
I plan on amending soil for a small blueberry planting this fall. The plan was to mix peat and cottonseed meal 50/50 and then take that mix and go 50/50 with the soil. How deep do blueberry roots normally go at maturity??? The plan was to mix this as deep as needed and also add some sand in the mix since the soil has a lot of clay. The blueberries will get full sun and I would imagine the soil will get pretty warm so a lot of mulch will be needed to keep the roots moist and cool. How much mulch is needed for hot areas and I am planning on using composted, acidified, cotton burs for the mulch.
