[Susan d.S.]

Here's a quick effort:

O My love’s like a red red rose
In a bed worms burrow in.
Thou hast hard roots and parasites
And thorns that pierce my skin.

Thou’rt choked with weeds and fallen leaves,
Infested plants and canes,
With Fungus, canker, cane dieback;
The pesticide, it rains.

Grey lesions spot thy flower head,
Thy buds brown and decay.
But I’ll abide ‘til cutting time
And spray ye every day

With lime-sufur and Mancozeb,
Captan and Triforine.
I’ll love thee ‘til the Flower Show,
Such beauties must be seen.
