Q: Some of the leaves on my mums look like they have spit on them. Is this anything to be concerned about?
A: The mum has been visited by spittle bugs. The sticky white encasement contains eggs. Spittle bugs are not know to be harmful. Insecticides would not be very effective on this so cut it off if concerned.
Q: I have a flowering maple. How large will it get and what do I do for it?
A: If it is in the ground, it can get to about eight feet in height. They grow well in filtered light. If you do not have that situation, put it where it will get morning sun (e.g., east side of your home). Late day summer sun can stress the plant. They bloom on new wood so occasional pruning in warm weather will force more flowers.
Q: What do I need to do to harvest seeds from my marigolds?
A: Late in the season let some of the flower heads remain on the plant. Once they have turned brown on the plant the seed is mature and harvestable. Pick the dried flowed and break it apart to separate the seeds. Store them in a sealed container in a cool dark place until ready to use.
