The foliage consists of fuzzy green leaves and lily-white efflorescence . There are both male and female flowers , and only the female person produce fruit .

Bottle gourds may have an stretch or rounded shape . Some may deform like a gooseneck and others may sport a dual bulge like a weightlifter ’s dumbbell .
The feeding bottle gourd has an honored space in chronicle as one of our earliest domesticated crops .

Two race have been identified , the AfricanL. sicerariavar.sicerariaand the AsianL. sicerariavar.asiatica .
Lagenariais the Romance give-and-take for feeding bottle , or flask . ripe hard - shell gourd have beenused for millenniaas nutrient containers , water jug , floats for sportfishing nets , and even consistence armor .
former Native Americans used them as musical cat’s-paw in religious ceremony , as well as birdhouse to attractinsect - eating violet St. Martin .

And while the tender immature fruit , shoots , leave , and seed ofL. sicerariaare eatable , it ’s all important to sympathize that this works contains a toxic chemical substance compound called tetracyclic triterpenoid cucurbitacin that is know to get serious and potentially lethal GI distraint .
Folks who consume it say not to use up any part or drink the extracted succus if it tastes “ bitter , ” but at least onedocumented hospitalizationfor GI hemorrhage point that this is a dangerous game to recreate .
In India , where it is known as dudhi , or lauki , L. sicerariahas been used for one thousand of year in Ayurvedic practice of medicine ’s Panchakarma cleanse , which reach the most of the toxin ’s purgative caliber .

L. sicerariais cultivated as a vegetable crop across Southeast Asia , and in Japan , where it is still used by traditional practitioners to treat ailments ranging from bronchial asthma to inflammation , and to stand centre wellness and resistant social function .
In today ’s American garden , it ’s a unique ornamental industrial plant that bluster vigorous flower vine and fruits that make sturdy , ornamental birdhouses .
Propagation
To grow your own flora , start with fresh seeds that are packed for the current growing season and come from a reputable purveyor .
Because of the long turn of days to maturity , you may want to get your seeds indoors four to six week before the last modal spring icing escort for your region .
Here ’s how :

When the seedlings have two sets of true leaves , acclimate them to the outdoors a few hours each daytime for about a week , and then fall them into garden filth at the same depth they are in their pots / cells .
How to Grow
Whether you ’re start up seeds indoors and transplanting them out , or directly - sowing them in the garden , you should do so after the danger of Robert Lee Frost has pass in the outpouring .
Select a full sun fix . If you live where summer afternoons are singe , a little afternoon shade is beneficial .
The stain should be organically rich and well - draining , with a slightly acid to neutral pH of 5.5 to 7 .

To determine your stain ’s acidity , you canconduct a dirt test . Soil that is too sweet ( alkaline ) is easy amended withthe gain of compost .
work on the soil to a friable eubstance , to a depth of six to eight inches , in a foot square patch of dry land .
rectify it as require per the results of the territory test , or just fuddle in a couple of goodish handfuls of compost for respectable measure .

Make a cumulus of the crumbly earth that is about six inch high-pitched and a infantry wide . Prepare as many hill as you wish , with five to eight feet between the mounds .
pose the cum up high helps to promote serious drainage and inhibit rotting .
Place four seeds in each mound at a depth of one inch . Point them downward , and let three inches between them .

As described in the case of indoor planting , they are less likely to rot in this emplacement than if you position them bland .
encompass the seeds and dab the dirt down firmly .
irrigate the soil and keep it equally moist , but not torpid , until plants are well establish .

Fertilizer is not required , but if you want to utilise it , choose one that is well - balanced and releases easy . Avoid product with an surfeit of N , or you may get lots of leaves and few fruit .
When you have seedlings with two sets of lawful leafage , thin the issue of plant life per pile to two . If you hoist up with two extremely vigorous vines , you could always thin them to one later , if you like .
The same start for transplants – industrial plant two in each pile , to give the vines plenty of room to spread as they grow .

I know it ’s operose to flimsy seedlings , but if you let them all mature , the works will be very confining together , fix air travel circulation , increasing ambient humidness , and stimulate them more prostrate to insect plague and disease .
As the vines begin to lengthen , you may determine if you want them to grow on the ground or over a social organization .
With flabby twist ties , like this product from Burpee , you’re able to civilise them to mature on the structure of your choice for a dapple - shade hideaway that adds upright landscape interest group .

Each software hold back a 16 - foot uninterrupted axial rotation that can be write out as desired .
Some time on the primer is beneficial , as the vines tend to rout themselves into the soil as they lengthen , make the entire plant additional bread and butter .

However , this effort to provide the plants with a stronger base may leave in some fruit emerge at primer story .
Gourds that remain on the ground are susceptible to flattening and decomposition .
To protect them , watch over the recommendation inRodale ’s Ultimate Encyclopedia of Organic Gardeningand utilize several inches of mulch ( I like uncontaminating drinking straw ) beneath developing fruit .

The pros at the Rodale Institute also recommend a side dressing of compost in the midsection of summertime , as flora are heavy feeder .
Side dressing is a technique in which you work food into the soil without touch the roots , in a radius that goes from the root outward to the “ dribble line , ” or edge of the foliage .
With vines , this can be slick , so just add some compost near – but not on – the industrial plant , around summer solstice .

At about this clip , you may find that your gourds are incur bulky . While the stalk are quite tough , some folks like to provide contribute bread and butter with a flaccid sling .
Now , let ’s retread .
