Blackberries are a fruit-producing plant that grow best when planted in a garden bed away from other garden vegetables. In contrast, lilies are flower-producing bulbs that grow best when planted in the fall season so they get an early start once the soil begins to warm. Plant the blackberry canes in the spring as soon as you can work a shovel through the soil and lilies in a flower garden, or around the perimeter of a blackberry garden. Lilies will not grow properly when planted between blackberry canes since they will not receive enough sunlight.
Plant blackberry canes in a garden area that receives full sunlight and has a well-draining soil. Set the canes in a hole that is 3 inches deep and wide enough for the roots spread out. Space the canes 24 inches apart in rows that are a minimum of 4 feet apart.
Water the soil around the blackberry canes with a deep soaking that moistens to a depth 8 to 10 inches immediately after planting. Provide supplemental deep-water soakings once a week through the berry production season.
Apply organic mulch over the planting bed to a depth of 3 to 4 inches. Pine bark or clean straw mulch works well to limit weeds and increase moisture retention for blackberries.
Fertilize blackberry canes starting in the second year of growth with a 10-20-10 fertilizer. Apply the fertilizer once blooms appear at a rate of 5 pounds for each 100 feet of planting row. Repeat the application after fruit harvest.
Propagate blackberry canes by digging out new shoot growth that appears at the base of the plant. Dig several inches into the ground to remove a portion of the root structure. Replant the blackberry shoots in a hole that is 3 inches deep and wide enough to spread out the roots.
Plant the lilies in a garden bed that receives full to partial sunlight and has a well draining soil. Amend the soil by working 3 to 4 inches of organic compost into garden bed to a depth of 12 inches.
Set the lily bulbs in a 6-inch hole so the point faces upward. Cover the bulb with soil and water generously to moisten the soil to a depth of 8 to 12 inches. Apply a 2-inch layer of organic mulch around the bulbs once the shoots appear in spring.
Provide supplemental water to the lily plants when the weekly rainfall is less than 1 inch. Lily plants do not require regular water applications until the shoots appear in spring.
Apply a 5-10-10 slow-release fertilizer to the soil surrounding the lily bulbs each spring. Follow the package instructions for the application rate based on the square foot of garden space.
Propagate lily plants in the fall season by dividing the bulbs. Cut the foliage to a height of 1 to 2 inches and dig the bulb mound from the ground. Separate the bulbs with your hands and replant the bulbs following Steps 1 and 2.
