Question Hi Ronald
I dont live in Florida I wish I did but only in the winter :-), I live in western Canada, but figured you could help.
We are having a very dry spring.
I dont have an irrigated lawn, so it took a long time to green up, and weeds have replaced much of the grass.
A feww weeks ago I put down some 'dry' grass mix which doesnt need as much water or cutting.
Its taking forever to come up.
Today I cut the grass and put down some 'weed n feed'.
Was this a good move?
Will it kill the dry grass seed shoots?
Also, it says to wet frass and apply, then NOT to water for a week?
What about rain? (If we get any).
Thanks!
Answer A certain amount of moisture in the soil is necessary to enable the plant to take up fertilizer and the weeds to take up the weedkiller.
If some gasoline is dripped on a dry surface, it sits there and evaporates; if the surface is wet, notice how the gasoline spreads and turns colors.
It is always a good practice to water the lawn lightly after applying any product; mainly to get the product off the grass blades... unless of course it is a 'foliar' spray... something like liquid iron.
If the weedkiller in the W&F product is 'pre-emergent', it most likely will inhibit the germination of grass seed. If it is 'post-emergent', chances are that it will not.
A heavy rain shower within 24 hours after application will wash the product off leaves. This is not good for products which must stay on the leaves to be effective. Heavy rain in the week following application can leach the product away or cause premature breakdown of the product. Either way, something is lost; effectiveness or the product itself. Track rainfall (or lack of it) every day for the week after application and if you have a concern, call the help line on the label and ask to speak to the 'Technical sales-rep". They are usually very knowledgeable and will give you sound advice.
