Growing Petha Vegetable

Petha grows well in tropical and subtropical regions that have long, warm seasons ideal for cultivating vines and gourds. Here are some tips for planting and caring for petha plants:
Ideal growing conditions and climate
Petha thrives in temperatures between 70 and 85°F and prefers sunny locations with fertile, well-draining soil. The vines can be cultivated as annuals in zones 10 and warmer by starting seedlings indoors 4-6 weeks before the last spring frost date.
Planting petha seeds or seedlings
Seedlings planted after the danger of frost has passed will produce earlier than direct sowing. Space seedlings or seeds 3–4 feet apart in furrows or hills.
Seeds should be planted 1/4 inch deep. Apply a 2-3-inch layer of mulch to retain soil moisture.
Care instructions through various stages
As vines grow, trellis or fence is used for support to keep fruit off the ground. Water deeply 1-2 times per week and apply fertilizer monthly through flowering.
Weed regularly to reduce competition. Pests include squash bugs, aphids, and mildew, which can be treated with organic remedies.
Common pests and diseases
Common pests include squash bugs, aphids, and powdery mildew, which can be prevented with good air circulation, crop rotation and by removing plant debris at the end of each season. Signs of pests or disease should be addressed promptly to reduce risk of spread.
Harvesting petha
Begin harvesting mature gourds 2-3 months after planting when the exterior has hardened fully and taken on a dull gray appearance.
The stem will naturally detach from the vine when lifted. Collect before frost and store in a cool, dry location for up to 3 months.

Preparing and Cooking with Petha

Once harvested, petha can be prepared and cooked in many enjoyable ways. Here are some tips for working with this versatile vegetable:
Selecting ripe petha at the store or from your garden
Opt for pethas that feel heavy for their size and have a dull gray rind free of blemishes or mold. The glossy white exterior will be hard when ripe.
Cleaning and cutting petha
Scrub well under running water and peel the outer layer using a vegetable peeler. Halve or dice the flesh as desired, removing any seeds. The inner flesh browns quickly, so prepare just before cooking.
Common cooking methods
Petha works well boiled, stir-fried, or sautéed. It holds its shape when cooked. Try boiling sliced petha for 5 minutes, then cooling for pakoras or fritters. Whole petha can be stuffed before baking, braising, or adding to curries.
Famous Indian dishes featuring petha
Petha pairs beautifully with Indian flavors. Popular preparations include petha nu shaak, a stir-fry with tomatoes and spices, and petha bhujia, chips seasoned with chaat masala. Other classic curries to feature petha are saag or aloo petha.
Storing leftover cooked or raw petha
Refrigerate peeled or cooked petha tightly wrapped for up to 5 days. For long-term storage, freeze sliced or cubed petha sealed in an airtight container for 2-3 months.
