Why Zinc Is Important To Plants. The 17 Essential Plant Nutrients! Ep 16 

u helped me wt my homework so much xoxo

Thanks for watching guys! I have two videos today because yesterday I missed an upload! My cousins were back for the first time in two years so they took the cake yesterday

Thanks for putting all the work into these. I love the science-based info.

Wow u post a lot , thanks for what u do!

Had a 3-year old lemon tree in a container, and looked healthy except I noticed many of the branch ends were dying. Googled it and it noted this was a sign a sign of low zinc and also showed pics of leaves that were dark green around veins, but yellowed in between, exactly as the new leaves on my tree. I had given it citrus fertilizer and thought I was covered…but apparently not. I bought other plant food with zinc (although only a tiny percent) and will try a bigger pot with new compost or other supplements.

Hey Ashley, thanks for all the great content this year. I have a minor in chemistry. You had me at ion exchange. Lol merry Christmas and happy new year. Can't wait for all the great content next year.

I totally thought it was gonna be oxygen.....just noticed this is 2 months old.

Second last vid of the series?! Noooo

Thank you for the vids. very informative. long story short...would you know anything about amending soil that has accepted laundry grey water for many many years...(standard detergents + bleach + oxygen bleach + borax etc) Might be a good idea for a video...since Using laundry waste water for irrigation is becoming more common in drought stricken areas and not everyone uses the eco friendly stuff. :) just a suggestion thank u for ur time.

So would volcanic rock have zinc in it?
