I am growing karela ( bitter melon) and bottle gourd in my balcony. Both Creepers are growing very well and I am getting a large number of yellow (bitter mellon) and white (bottle gourd) flowers. But there is no fruit. I had almost got 80+ 30 flowers till now. But I have one bottle gourd and one baby bitter melon. Plants are around 2 month old.
There is ample sunlight of around 6-8 hours.
What shall I do to increase productivity? I am regularly adding Compost (bought from SPAR, brand Bio-compost) and Vermiculite to plants.
vermiculite is of no nutritional value to plants. it only increases the water holding capacity and also improves texture (little bit). compost addition will be of help. bitter gourd needs pollination to set fruits. most of the flowers could be make flowers. the ratio of male to female is usally about 10-14:1 . This is just an observation , your mileage might vary..don't sue me 🙂
I thought vermiculite provide a lot of nutrition and it gets saled here in my area at in one kg bag for Rs 50!
Ratio of flowers on creeper is much high around 25:1. Other problem which is peculiar of bottle gourd is that baby female buds slowly starts turning brown and dies out! I have photo of that in album https://plus.google.com/photos/117160771024579396482/albums/5768417027072537217 Could this fungal problem ( i am told powdery dew) be the cause?
This is not happening with male flowers. For Pollination I do not have much help from insects! I am pretty clueless about this.
I have a lemon tree which flowerd for the first time this season after 3-4 years... but none of the flower bear any fruit... and now the tree has grown lots of branches with huge amount of foliage. This is the first time I have grown lemon tree so don't know much about it... If anyone knows any thing about lemons... Please share.
I have a similar thing with ridge gourd. There are fruit bearing flowers, but they turn pale and do not grow. So far out of 10-15 fruit bearing flowers only one has become a fruit. I think pollination helped but not sure.
For bitter gourd, there are lots of male flowers and very few 4-5 female flowers. I pollinated 2-3 and they seem to grow well.
There were lots of insects in both gourd plants and even on okra. the leaves would curl and plants would not grow further. Spraying gau-mutra mixed with water and cutting off infested branches has helped. Today I have prepared organic insecticide. Eager to spray it tomorrow.
The plants are in pots in balcony with a soil mix of cow dung, some vermi-compost and neemcake.
Will adding more vermi-compost help in survival for fruits? Any other suggestions are welcome as well.
Hai usha madam i am having experience in pruning rigid/bitter/snake gourds.Prune the end of main stem when it reaches 1mtr long this will shock the plant ,and laterals begin to grow from end.Allow 4 laterals from the main end,remove all the laterals below till the bottom end of plant. The main stem will produce only male flowers &laterals produce females.When the laterals produce 6 leaves prune the end,allow the 6 leaves to produce 2nd generation laterals,repeat the process for remaining laterals.This process will endure grow of laterals only,theme in this is vine wants to grow fast by, pruning the main shoot which giving male flowers having habit of growing lengthy puts its energy to laterals which is giving females.Repeat the process again as for you follow the growth.Over all pruning leads only females.
It can be that your plants are getting TOO much nitrogen... which causes leaf/plant growth at the expense of fruit
maybe addding something that contains.. phosphorus....will help
check if you are adding too much of some additive/fertilizer that mainly has a high nitrogen ratio (which is the case with many)
