I recently transplanted some Zucchini seedlings to one of the cold frames in our backyard. It looks like the newer leaves are more yellow than they should be…or at least what I think they should be…
I’m thinking there is either a difficiency in Nitrogen or Sulfur. Since I am not sure which, I decided to fertilize with 2.3mS of magnesium sulfate.
This should let me know if the yellow coloring is due to a lack of sulfur….hmmm…or magnesium.
I have a ways to go before I can look at a plant and diagnose the deficiency…until then I will try then try again.
Liquid fertilizers burn new roots and young plants. They’re basically chemicals that “burn” until they settle in the dirt to be extracted by roots. Too much of it is a bad thing. I highly recommend earthworm casings.
This is great stuff! So much to learn. In a fun way. From observing and adjusting. …and eating!
