A Detailed Guide to Growing Luffa in Open Ground in Spring

Luffa is a common vegetable that can be served cold, stir-fried, braised, made into soup, or juiced. It can also be used medicinally, with effects of cooling, promoting urination, invigorating blood, clearing meridians, and detoxifying. Below is an introduction to growing luffa in open ground in spring.

1. Soil

Luffa is not strict about soil requirements, and all types of soil can be used for cultivation. However, for high yields, it is best to choose loam or sandy loam with deep soil layers, high organic matter content, good air permeability, and strong water- and fertilizer-holding capacity, with a pH of about 7. If the land is poor and thin, sprinkle lime powder before planting to adjust the soil pH and avoid it being too acidic or too alkaline.

2. Sowing

Sowing is generally chosen around Qingming Festival, but because temperatures in the south warm up faster, luffa can usually be planted starting around the Beginning of Spring, while in the north planting must wait until March to April. Place the luffa seeds at a temperature of about 25 degrees to sprout, rinsing them with water every day until the seeds show white, at which point they can be sown. Hole sowing can be used, placing 3-4 seeds per hole; after sowing, cover with soil, water, and cover with dry grass to retain moisture.

3. Fertilizer and Water

After the luffa seedlings emerge, apply manure water 2-3 times; at the early flowering stage, apply additional compound fertilizer or peanut bran; after every two harvests, apply additional compound fertilizer, urea, and potassium fertilizer. Luffa needs a lot of water during its growth period, so the soil should be kept moist in the early stage of growth; it needs the most water during flowering and fruiting, so on sunny days water in the morning and evening; on rainy days, pay attention to drainage to prevent water from accumulating on the beds.

4. Trellising

Luffa is a climbing plant, so it needs a trellis. When the vine reaches 30 cm, bamboo poles can be inserted to build an A-frame trellis. After the trellis is set up, appropriately coil the vine and press down the runners, and when female flowers appear, guide the vine upward.

5. Harvesting

Luffa has a very strong continuous fruiting habit, and in summer the fruits develop very quickly, taking about 10-12 days from flowering to harvest. Harvest promptly, otherwise the luffa easily becomes fibrous and inedible. It is best to harvest in the morning, and when harvesting, do not pull by hand; simply cut it off with scissors. In the later harvest period, promptly remove diseased and old leaves below to avoid affecting ventilation and spreading disease.
