why are my day lily leaves turning so yellow?

Question

I also have geraniums that are many generations from my wifes grandmother that are showing some type of spots on the leaves, then also yellowing.  We have a Hoya that had some yellow bugs that we did use Malathion oil on and systemic fungacide on that helped us overcome some type of mites we had on a large pony tail palm.  Sys Granules were also used for the palm and have gotten rid of the mites - we live basically in a bird sanctuary where no one uses any type of substance to rid it of mites, bugs, insects.  And we prefer not to, but some of these plants are very very old and passed from generations so we would like to save them.....

Answer 1

I don't like to use chemicals if I can avoid it

after the sun goes down mix up 1 teasp liquid hand soap & 1 qt water and spray.............spray again if it rains.  this is the safest method to use around birds.

we had so much rain this year that it is effecting all the plants......be sure to have the best drainage for them.....sounds like you have a lot of plants.......so either replanted on higher elevated or do a drainage ditch so that the ground drains off the excess water.  In the fall you could amend the soil, with mulch, old horse manure, some lime, hay or straw and cultivate it....when you rake finish the ground on a slight slant for good drainage.
