keeping leaves healthy
In case anyone encounters this problem when trying to grow geraniums from seed:
Last year was my first year growing geraniums from seed. Started in Dec, did well until it was time to trim back the center for them to branch, then lower leaves started turning yellow/red and falling off.
From investigation found out that
1) our well water has low Ca:Mg ratio
2) geranium seedlings/plants need a higher Magnesium content.
So last year i had to dip them in a weak solution of epsom salts to bring them out of it.
This year started them in Jan,they are doing wonderful, and I am using a fertilizer with a higher %Mg in it.
