Growing ampalaya

This is a tropical plant, but like many melons and other gourds, the conditions can be achieved to make a success of growing it in a wider climate range.

Here are the key points.

Climate

If you would like to grow ampalaya, you’ll find that the best USDA plant hardiness zones for ampalaya are between:

  • Zone 9 has a minimum average temperature range of 25°F to 30°F (-3°C to -1°C). This zone includes states like Florida, Georgia, and Texas.

As you can see warm weather is your friend, but you may be able to grow successfully in slightly cooler climates by using a hot house.

However, ampalaya thrives in the full sun.

When do you plant ampalaya?

Ideally, ampalaya should be planted out in the winter (October to February) as the flowers are more likely to be fertilized in cooler weather leading to greater yield when warm weather arrives.

Ampalaya soil requirements

Ampalaya can be grown in all soil types but prefers sandy, loamy soil that drains well.

If the soil is nutrient-poor it should be prepared by adding organic material. An acid pH of between 5.5 to 6.7 is preferred.

Starting ampalaya from seed

To grow ampalaya from seed, you need to help germination along by breaking the tough seed coat of the ampalaya seed.

This can be done with a nail cutter or snips.

The seeds should then be soaked overnight in water, wrapped in a damp cloth, and left in a warm, dark place until the seed coat breaks further.

The seed is ready to be sown in a suitable potting medium, which drains well when the young vines are watered.

Works Best – Sow 2 to 3 seeds per pot. The seeds will germinate in 5 to 10 days when well-watered.

Transplanting ampalaya 

Ampalaya seedlings can be planted when it develops their first true leaves.

This is usually around the third-week post-germination.

Alternatively – Many growers move the young plants to sacks or planters rather than directly sowing them into the soil. 

Feeding and watering ampalaya

Though ampalaya grows in hot weather, it should not be excessively watered.

It will not thrive in waterlogged soil or excessively humid conditions, which can promote disease. Water every couple of days and at the same times as feeding. 

Feeds can be applied weekly in the form of organic probiotics or NPK liquid fertilizer.

Some growers use urea of hummus-rich compost before planting out ampalaya. 

Support ampalaya with trellis or frames

Like any fruiting vine, ampalaya loves to climb.

You will need to provide a trellis or frame to provide the necessary support, which improved the quality of fruit development.

You can purchase a pre-made trellis or create a custom structure that is capable of supporting vertical and overhead growth.

Use twine to support the vines that can grow as long as 16 feet.

Pruning ampalaya growth

Good pruning will improve the vigor, quality, and flavor of the ampalaya you grow.

Like tomatoes, prune the leaves and any lateral vines that are within 1 meter of the ground. Concentrate growth on your fruit by cutting any unproductive vines.

You can eat them fresh or cooked. Defective fruits should be similarly removed.

How long does ampalaya take to grow?

Ampalaya grows at the same pace as squash and other gourds, producing fruit after 60 to 70 days.

Harvesting ampalaya

You can harvest ampalaya fruit by supporting the gourd in one hand and cutting the peduncle with a sharp knife.

Do ampalaya have pests or diseases?

  • The most damaging pest of ampalaya is the fruitfly which can rapidly deteriorate and destroy developing fruits. They are controlled by wrapping the fruit to protect it from the fruit fly or spraying attractants to divert their attention. 
  • Bacterial wilt is a common disease of vine fruit and gourds and can rapidly spread and kill ampalaya plants. This disease can be prevented by encouraging good microorganisms in the soil and removing any disease or damaged plants promptly.
