Fenugreek in Alabama

With our heat I have had no success with fenugreek in the spring. Could it perhaps be a successful fall planting here in Zone 8B Alabama, USA?

It certainly seems worth a try. We have not had anyone reporting to us on growing fenugreek in hot climates so I can only guess.
I would start plants in pots indoors in late summer and put them outside as soon as the worst heat is over. Otherwise you may not get enough growing season to mature the plants. If winter does come before maturity, you might be wise to have some bubble wrap ready to put over the plants on cold nights, making sure that the edges are held down properly – maybe with boards and rocks – so no frosty air can sneak under the cover. Remove after sun-up.
