PREPARING SOIL BEFORE PLANTING
In preparing soil for planting a vegetable garden, it's a good idea to first rid the area of weeds. Then dig or till the soil to a depth of at least 8 inches. In the process of digging, you can add organic matter, such as compost, to help improve the soil texture.
Banana passionfruit can take a long time to germinate, but soaking overnight in lukewarm water can help speed the process. Keep the germination medium moist and warm (70 degrees F).
