The listing, 10 Luffa Sponge Seeds Plant Loofa Loofah Lufah has ended.
Seeds can take up to 2 weeks to sprout. Pre-soaking in warm water for 48 hours will speed germination.
Grow the luffas on a sturdy, tall trellis or a fence at least 5-6 feet high. Without a trellis, vines will quickly overrun the garden. Mulch mid-summer with compost or grass clippings, to help conserve moisture and control weeds.
When the gourds are ripe, their skins will dry and the stems will turn yellow. Full-size fruits that are still green produce soft, fine-textured sponges that don’t last. Green fruit is also very sensitive to frost – if no yellow or dry fruit have been produced by frost you will need to provide protection to give the fruit more time to ripen.
Here are two techniques you can use to make a sponge, if you get some gourds that ripen:
Let the ripe gourd dry for 2 weeks. When its skin has hardened and turned brown, open the larger end of the squash and shake out the seeds. Soak the gourd overnight in water, then peel off the skin. Let the gourd dry in the sun.
