Preparation of the soil

Loosen the soil to a depth of 8 to 10 inches and remove any rocks or debris before planting. To increase the soil’s nutritional level, mix in some compost or well-decomposed manure. To prevent the soil from harming the plants, ensure that it drains adequately.

Plant the slips

Water the slips

Water the slips well after planting to help them develop roots. Once a week, give them a thorough watering, ensuring sure the soil is kept wet but not soggy. Take careful care of the soil by tapping it around the plants.

Train the vines
