Red reflective mulch is available at Gardener's supply. It does help the tomatoes grow better.

I use newspaper for mulch to hold down weeds because I don't have a lot of access to other kinds of mulch. And I don't like to get the free mulch because they almost always have centipedes and occasionally nasty weeds in them.
I cannot use pine shavings for mulch because of termites but it would be a good option for people in the North where termites are not as big an issue.
I do use pine needles when I can get them. They break down slowly so they last awhile. It does not pack down so air and light can still get through and it suppresses most weeds well. It cannot be used on the onion family.
When I use tree trimmings for mulch the weeds grow through and right on top of it. It packs down and I end up having to water the mulch before I can water the plants. I have used it on walkways.
Lately, I have been trying a new tactic. I use the newspaper and compost as mulch. I am trying to see if I can reduce tilling. Supposedly, the soil microbes will pull the compost down into the soil. It has advantages in my established border bed but I still have to turn my vegetable garden because of the weeds. The newspaper works better there.
Happy gardening in Hawaii. Gardens are where people grow.
