Is there anything I can do about my seasonal asthma?

Yes. There are lots of things you can do. I would start with identifying your triggers. Since you said it is seasonal, that could suggest environmental allergies are a trigger. If so, avoidance or reduction of exposure to those things can help. For example if you have central air, use a better "allergy" filter. There are medications that could help too. This space is limited-talk with your doctor.
In extreme cases, ...Relocation to an area with a more beneficial climate might be a good idea.
