My previous two posts on the same subject commented on the germination, and growth of calabash and other indian vegetables in the UK. Unfortunately for us here in the United Kingdom, this was the wettest summer in the last 100 years. With lack of sunshine and lots of rain, many of the experiments I had planned to conduct on the efficacy of growing traditional indian vegetable came to nothing.
However, it was not all doom and gloom, and I’ve actually managed to harvest a few calabash (lauki, dudhi) this year (see picture below). The plants are now well over 10 feet long and have many young fruits on them (sadly, I think the winter will catch up and kill them before they get a chance to mature).
I have also had limited success with indian green aubergines (but not spectacularly).
Take-home lessons for 2013
At the end of the year, these are the lessons I’ve learned.
- Start as early as possible with all Indian vegetable seeds (to give enough time to flower and fruit)
- Use a heated germinator to maximise chances of growth. Germinate a second round of seeds a month after the first to use as backup
- Keep the plants away from draughts, keep inside polythene bags to sustain growth
- Gradually acclimatize to outside when all danger of frost has passed
- Do not over water.
- Plants such as Lauki and Karela are vigorous climbers and therefore need stable and strong support. They also grow really long (10 feet or more).
- Once the first flowers appear, feed once a week with high potash fertilizer like tomorite.
- Keep well watered
- Beware of mildew (using a spray of 1tbsp baking soda with one teaspoon of dish washing liquid does wonders!)
- Keep harvesting regularly to keep the flowers going.
