KEEPING THE FOOD PRODUCTION GOING DURING HOT HUMID SUMMERS

Green Harvest carries a range of seeds ideally suited to hot, humid areas. To make finding them easier on the website  below is a list with short description and a hyperlink to the right page.


Gardeners in subtropical and tropical areas face a range of challenges in the vegetable garden during the ‘wet’. Pests and weeds can spread in the blink of an eye, with fruit fly and fungal problems being particularly difficult to deal with.
 

One way of dealing with this season is to ‘put the garden to bed’, by spreading a liberal amount of mulch and refraining from sowing seeds until the weather starts to cool down in March. This doesn’t mean there is nothing to harvest, only that the harvest is limited to perennial, tropical edibles such as  asparagus, arrowroot, bamboo, cassava, chillies,  choko, ginger, kangkong, lotus, pawpaw, pigeon pea, sweetleaf, sweet potato, taro, waterchestnuts and yam.

Many of these plants are available seasonally more info
 

Alternatively you can substitute more familiar vegetables with hardier ones that are native to tropical regions and will withstand waterlogging and high humidity without collapsing in a screaming heap. Angled luffa or New Guinea bean will substitute for zucchini without the powdery mildew problems, snake bean will continue to set pods during very hot weather and is resistant to bean fly. Ceylon or Egyptian spinach are both rust resistant and won’t bolt too fast as the weather warms up.
 

The book Tropical Food Gardens: A Guide to  Growing Fruit, Herbs and Vegetables  is highly recommended to help gardeners in the tropics.

Psophacarpus tetragonolobus

syn. Goa bean; kacang botol, kacang kelisa (Malaysia); kecipir (Indonesia); thua phuu (Thai);  sigarilyas (Filipino); đậu rồng (Vietnam); jaat (Sundanese); sirahu avarai (Tamil)

Winged bean is a vigorous, tropical climber with mauve-blue flowers and four-angled pods with wavy margins. The pods, leaves, flowers and tubers are all edible. It is high in protein: the seeds contain 34% protein and 17% oil; the root contains 20% protein. If you are growing it for pods, leaves or flowers, grow it on a trellis; a trellis is not needed if you are growing it for the tuberous roots – let it sprawl. Of course, you will need to replant annually if you are harvesting the roots. The young leaves (top three sets of leaflets on a shoot) are cooked and eaten. The flowers taste like sweetish mushrooms. It is among the world’s most effective nitrogen-fixers.

A short day length (11-13 hours of daylight) during hot weather is required to flower, so it is not suitable for temperate areas; it is also very frost sensitive. It grows to 3 - 4m. Wait for warm, humid weather before sowing; in the subtropics sow November - December; in the tropics sow October until January. It will grow on a wide range of soils but requires moisture to do well; it tolerates acidity.
