I'd actually think the red plastic mulch would help keep the soil splash down -- certainly is reputed to be the case for IRT, clear, and planter's paper mulches. I'm under the impression you're using SRM-Red or Red Tomato Booster red plastic sheeting. The disadvantages I have heard of for the red plasic are 1) that it allows weed growth underneath and 2) it doesn't allow vapor/water passage. Betsy On Thu, 27 Jul 2000, EDMUND C.
