FREE: 10 Loofah Seeds

Wow! There is a lot to growing this plant...Growing luffa requires a certain amount of patience. It's not a typical garden plant. It grows slower than most gourds. Sometimes the seeds can be slow to germinate. Luffa is a hot weather plant and growth slows in cool weather. The flowers appear over an extended period of time, blooming sequentially as the vine progresses. The vines can grow 30 feet(10m) long over the course of a growing season. Once the fruits form it may take a long time to fully develop fiber and dry for harvest. Then the work of picking, peeling, and cleaning happens late in the year. Luffa requires about 140 to 200 or more frost free days, depending on the location and variety grown. It needs lots of sun, warmth, water, good root nutrients, and a large strong trellis. The vines will grow on the ground on a well drained weed-free flat surface but tend to produce curved loofahs. Luffa can also be grown in containers around 5 gallon size. Containers must have good drainage and can't be moved once the vines attach tendrils to other objects. A small pot starter trellis can be used in the container until it is permanently located. The ideal soil ph is neutral to slightly alkaline. Some lime might be needed for acid soils.

It's a neat plant, though.
