Pine and straw are two different things, as far as I know. If you need pine bark, sometimes pet stores have it in small quantities. If you want straw for mulch, look for feed and tack stores.

Pine straw bales are baled pine needles, aren't they? I have not ever seen that product offered for sale in southern California.

lgteacher, "pine straw" is a common mulch in the Southeastern US, and is pine needles. I learned that reading other forums which have Southeasterners posting. It's not a common California term, because mulch/soil amendment tends to be a local product (due to transportation cost) and we don't have a lot of pine lumber mills here.

Starfinder you may have to collect it yourself, or if you want to acidify soil here you have to use peat moss, azalea/camellia mix, or soil sulpher, and a bark product. For my blueberries I mulch with peat moss as a first layer and another type of mulch over that, to keep the peat from drying out. Gardening is all local...

Hoov ~ what kind of blueberry produces for you? How long have you had them?
Do you know your chill hours? I've been eyeballing them. Thanks.

Starfinder ~ happy collecting! I found a quiet block of long needled pines. Love them. Only thing that doesn't disappear in a year in this adobe soil.

I have 'Bountiful Blue' and 'Sunshine Blue'. They produce great every year. I've had them--6 or 7 years now, planted in the ground with camellia/azalea mix and a yearly small dose of soil sulfur. The biggest problem is keeping the birds from stealing the fruit.

The newer hybrids available are based on Southeastern species, require little or no chill, and are very heat tolerant.

Thanks Hoov. Writing them down.
