1. I have heard that pine straw is flammable. Is this true?
Yes. Pine straw is extremely flammable and should not be used next to your house! The problem is not just that pine straw will burn, but when compared in flammability tests with mulch which will slowly smoulder, pine straw burns quickly with flames 3-4 feet high. Many cities have banned the use of pine straw within 10 feet of condominium and apartment buildings because of the extreme danger of destructive fire. A carelessly dropped cigarette is enough to cause a serious pine straw fire.
2. Does mulch attract termites?
The research seems to indicate that termites may be attracted to any wood in your flowerbeds, such as old roots or stumps. Any wood food source will do. However, the real problem is moisture next to the foundation of your house, so pine straw and pea gravel are just as bad. It is best to put a very thin layer of mulch from the foundation of your house out about six inches, and try to keep that mulch as dry as possible by not planting anything within those six inches. Termites cannot live in dry conditions and must have cover to do their work. Here are some articles by leading universities that may help:
3. Can I buy creosote? What can I use to keep my creosote fence black?
No. Creosote is a restricted use chemical and can only be purchased by a licensed treater. A creosote fence never has to be painted unless you want to for appearance reasons. A mixture of asphalt sealer and an oil based wood preservative can be mixed and painted on your creosote treated fence to maintain the black color.
