My free got rust fungi too. About to use it before too late

To treat rust on houseplants, first remove all leaves, tips, and buds with visible rust symptoms. Then treat with a fungicide - neem, copper, sulfur, or biological fungicides such as Monterrey Complete disease control are organic options and are usable on houseplants, but do the actual application outside or in a sink or bathtub to avoid risk of staining fabrics, carpets, or furniture. Thanks for the inquiry!

I haven’t evergreen tree that’s browning out.
Should I apply a copper fungicide to it only in the winter months? How often should I do it?

[@shonnardsnursery]

Good question, thank you for asking!
Before applying a fungicide to a needle-type conifer, be very sure about why you are seeing browning - mites are a much more common problem than fungal diseases on a confier tree, and heat and drought stresses should be considered as possible causes. Get help from a nursery professional or similar
Copper is very risky to apply when weather is hot, I generally stop using copper during the summer. Copper application can resume in fall, often as early as mid to late September if weather is co-operative (high temperatures staying below 85 degrees F for several straight days).
Be aware that copper applied to "blue" needled conifers strips the part of the needle that produces that color, and it won't come back - new growth that replaces it will color up normally.

I believe my amstrong maple is affected. It is june 16th, is it too late to spray or can I still do it? Thanks!

[@shonnardsnursery]

Thank you for your question! Be cautious with copper fungicides as the weather warms up; different forms of copper have differing levels of risk, but generally I stop applying it when temperatures are consistently above 75 degrees F for the highs. For leaf spots and fungal canker problems later into the season (typically around late June into July here in the Willamette Valley, Oregon area), fungicides containing chlorothalinol (Daconil, Fung-onil) are pretty effective, and relatively safe to use.

Safety glasses and gloves when mixing?

[@adenbuford7396]

Yes! And while spraying. Also when mixing, realize that it is very acidic and can stain any object blue very easily.
