I had a quick question, because I'm trying to figure up my mulch and fertilizer needs for this Spring. I had bought my father a couple of blueberry plants, among others, because that's what he wanted for his birthday. They've been in the ground about 2 weeks and I've been watering everything, but I need to get it mulched before the hot dry weather kicks in.
In South Carolina, we have the Clemson Ag Extension which puts out great info on local plants and their care. They suggest making a mound around the plant of peat moss and sand to help with water amounts and acidifying the soil. The say that if you mound it you have to water it more often.
Being honest, I wouldn't water the 2-3 times per week they say you need to, with dry spells, using this method. I use a mulch that goes on sale every year made of 100% ponderosa pine bark. It seems to work well.
My question is, should I use the peat/sand mix on the blueberries and my azaleas and rhododendron, and if I do, will it help cool the soil and retain moisture the same way as the pine mulch? If it's going to be helpful to these plants and work about as well as the pine mulch, but I don't want to have to replace it but once a year and I don't want to water it very much more often than I do with the pine bark. I'd much rather use an acidify fertilizer to achieve the same effect with the bark. Thanks for the help.
