Mix rich, moist and quick-draining potting soil for the jasmine. Use 1 part organic compost to 1 part garden loam for an ideal base. Don't use soil from the garden, as that may contain weeds or pests. Fill the pot three-quarters full of your soil mixture.
Turn 5 to 6 cups of well-rotted manure into the soil for added nutrition. Use manure from compost heaps, manure piles or used animal bedding to guarantee rotted, broken-down material. Old horse bedding also incorporates straw and hay for more nutrition. Don't use fresh manure, as it burns new plant roots.
Plant the jasmine in large, heavy pots with drainage holes for balanced and space. Use 10- to 20-gallon pots to allow root growth, with wide diameters for foliage growth. Smaller pots may not balance jasmine, or give them enough room for extended growth.
Give the jasmine new compost and manure amendments halfway through the summer, using the same guidelines in regard to manure consistency. Turn the new amendments into the top 2 inches of soil to maintain soil quality and nutrition. This step replaces commercial fertilizers.
Give jasmine new compost and manure additions again in spring, when the plant comes out of winter dormancy, to fertilize the plants and maintain healthy growth and blooming.
