Why BMI Is a Crock, in Pictures. So, the Guess The Rotund's Height and Weight game gave me an idea. (Oh, and hey, if you want to see a scatter graph of the results, there's one here now.) I talk a lot about how BMI is bullshit, but we all know talk is cheap.
As suggested in the above links (Thanks! ShellaB, for posting those links -- The first one was especially useful.), you can use monofilament plastic fish line to tie the fern to the basket, if needed. I stuffed my staghorn's basket with a combination of leaf litter, spaghnum, and Spanish Moss.
A staghorn fern (Platycerium bifurcatum) is a plant that requires more than an average hanging basket. When grown outdoors in U.S. Department of Agriculture plant hardiness zones 9 to 12, the epiphytic evergreen can reach more than 100 pounds and requires the heavy-duty support chains can give.. Measure the circumference of the tree limb from which the plant will hang. The limb must be sturdy enough to support the weight of the growing plant; some staghorn ferns reach 300 pounds.
