HELP! I worked so hard building a new deck..let it cure for 6 weeks then cleaned and sealed with thompson's best... Every year I have the most beautiful gerber daisies.. this year they just have not done well... struggled with mold (BLIGHT) constatly... now my new deck is molded ! I t seems that I can see spores also... can the BLIGHT be moving from my plants to my deck ??? I need to know before I re-do my deck OH NO!!!!:furious: Thompsons advanced water seal has given NO protection to this!
