How to Grow Healthy Sea Grapes

Sea grapes (Coccoloba uvifera) are evergreen shrubs or trees native to tropical areas of North and South America. The plants’ ultimate size depends upon their location. Sea grapes growing a significant distance from salt spray may reach heights of up to 50 feet, while those closer to the ocean range from 6 to 10 feet tall. Sea grapes produce clusters of edible, reddish-purple fruits in summer. They thrive in full sun or part shade and require minimal attention.

Instructions

- 1
  Cut open fully ripe sea grape fruits and remove the seeds. Rinse off any clinging pulp under running water.
- 2
  Loosen the soil with a spade at the planting 6 to 8 inches deep.
- 3
  Sow the sea grape seeds at a depth equal to 1/2 their length.
- 4
  Monitor the soil’s moisture level closely during the first two to three months after planting. Add water when the top 1/2 inch feels dry. Water established plantings only when conditions are extremely dry.
- 5
  Pull weeds from around the sea grapes as necessary.
- 6
  Feed the sea grapes in the spring with 6-6-6 fertilizer applied at a rate of 1 pound for each inch of trunk diameter. Work the fertilizer into the surface of the soil and water soil right after feeding.
- 7
  Trimming the lowest branches allows people and cars to easily pass beneath the sea grape.
- 8
  Pruning damaged growth keeps sea grapes looking healthy and prevents further breakage.
- 9
  Examine the foliage for signs of disease or insect infestation. Signs may include discoloration, spots or dropped leaves. Contact an agent in your local extension office for help with diagnosis and treatment.
