I hope this has not been beat to death, but is there any benefit of liquid other than price over granular. I am mainly interested in the pre emergent and fertilizers. I know that post is always better with spray. The reason I am wondering this is because I am thinking of changing gears alittle bit. I have always been mainly maintenance oriented with landscape installs and applications on the low end. In 08 I went from running three trucks on the maintenance down to just me and my son. My son is ready to start pursuing other interest and it is going to be just me and I do not know how much longer that I want to keep beating myself down with the maintenance. I now only have a Pro Lawn shielded 52" sprayer, Lesco spreaders and several back pack 4 gallon sprayers. I am interested in the ride on units such as the Z spray and T 3000. I know these are good for low volume post weed spray but I do not feel they will handle pre m and fert other than granular. I have always used granular so that does not bother me. I guess what I really want to know is a skid type sprayer really necessary? I really do not want to use another truck and pull a hose around right now. Please give your honest opinions. I know everyone's needs and feelings are different.
