Light spectrum, color of sheer curtains and Dracenas!

Hi People! I recently got cream colored sheer curtains to filter bright direct sunlight; it's a SE facing window with very intense morning light.
QUESTION: I'd love to purchase the black version and the deep blue version of this sheer curtain but am worried that the colors will limit the necessary light spectrum that the plants need. Am I fussing for nothing or is my concern valid? I'd really appreciate your feedback as there is nothing online that speaks to the color of sheer curtains, their affect on light spectrum, and whether or not it has any positive or negative impact on plants. (I have 2 Dracenas. I'm not worried about the cream colored curtains.) Thanks, People!

insect eggs? fungus?

the pictures are "dead" branches of a white lilac, the larger mass is too high for me to reach, the smaller mass was sort of "gooey" inside, and seems to be coming from under the bark? my master garden friend was stumped. Is this a good bad or neutral problem?

Is this bad

That is a dead boxelder tree stump. The red slimy stuff dissipated about 2 pm that pic was taken at 9 am. I have 2 dogs and two young children that play in the yard is it safe

Like to learn all you can about EAB? Just ask Scottie AshTree Seed.

I am an Arboriculturist from Chicago who after helplessly watching thousands of American Elm trees get killed by DED when young, vowed that if my generation was in charge during another mass tree killing event in the future.

In order for public to make well educated, best practice decisions.
