I've never tried taking cuttings from magnolias but I found this elsewhere which you may find helpful

""Cutting propagation is preferred for most magnolias. However, rooting potential of cuttings varies considerably among cultivars as well as among species. Magnolia denudata, M. acuminata, and M. grandiflora are considered difficult to root from cuttings.
Soft to semi-hardwood cuttings should be taken from juvenile plants whenever possible. Wounding may be beneficial. Cuttings should be treated with 5,000 to 10,000 ppm IBA and placed under intermittent mist. Cuttings usually root within 6 to 12 weeks."

Thanks Anchorman, I have no idea what type of magnolia it is I just know its in the wrong place and that its, been in for at least twenty years. I have just taken some cuttings any way, I will just have to hope for the best.
