Hello again, hello Bob,

Addendum, depending on species, letting flats dry out too much can prove
fatal, and having a saltbuild up in the soil isn't always beneficial,
impedes growth rates.

Lastly I believe Marathon to be expensive, but as I have no personal
experience with it as it is unobtainable in Sweden, and therefore cannot
comment, I would like to ask is anyone else would like to supply more
information?


Thank you!

Ingrid ( Sweden, and it looks to be a sunny day!)
