Re: weekend chores

hi, kathy, sorry i'm so late in answering, but i just uncovered you message. yes, i think the temp is important [don't know if it's 50, though]. yes, the plant has to be actively metabolizing. it should be applied morning or evening, not at noon when the plant is having a metabolic siesta. no, it does not lose it's potency--probably forever--if kept in an airtight container.

the most important thing about roundup is the formulation. the "label" [governmentese for instruction booklet] gives specific formulations for plant types/kinds/species. if you overdose [that is, use an enriched mixture on the assumption that more is better], you will kill the plant all right, but you will kill it before the poison reaches the roots. to work properly, roundup has to be absorbed by the plant to kill the roots because it turns harmless in the soil, and hence can't attack the roots from the outside. the general rule we use at the nursery is to mix to the label requirement and spray twice 1 week apart.

Jim..When using Roundup..do you feel the temp has to be above 500 and the
plant actively growing for it to work well? Also, do you feel it loses it's
wonderful powers if held over from last year? Kathyz5
