Get the best of both worlds by growing a plant that will complement your garden and landscapes while providing you with food, the sea grape tree is that plant. This evergreen is native to the Bahamas, the Caribbean, Bermuda, the Greater and the Lesser Antilles, South Florida, and the West Indies. These trees prefer a tropical climate where they will not only grow well but provide an abundance of sweet berries.

Sea grapes (Coccoloba uvifera) is a species of flowering plant in the buckwheat family, Polygonaceae, this evergreen plant makes a great hedge especially when planted in coastal areas because of their high salt tolerance.

When planted in coastal areas seagrapes help to support sand dunes, along with helping to protect upland structures from storm-induced erosion. The canopy of the sea grape provides a habitat for animals such as gopher tortoise, songbirds, beach mice, and lizards. A number of birds and mammals feed on the berries. In this article, we will be taking a look at how to successfully propagate sea grapes increasing their numbers in your garden along with some important health facts.

How to Take Sea grape Cuttings

The best time to take sea grape cuttings is at the beginning of spring.

1. Before taking your sea grape cuttings prepare the soil by mixing a 50/50 ratio of perlite and potting soil that has been sterilized in 6-inch pots or containers that are clean. 1-gallon containers can also be used,  The containers should have holes for water drainage.

2.  Chose a stem/ stems that’s healthy and with a sharp hand pruner that’s clean remove the stems. Each cutting can be 3 to 4 inches.

3. Remove all of the leaves from each stem allowing only the two leaves to remain at the top or at the tip.

4. Moisten the soil with water followed by adding your sea grape cuttings, or you can add root growth hormone (optional) if you prefer. Now as you keep each cutting erected firm the soil around it by gently pressing.

5. The cuttings should now be moved to a location that gets indirect bright light.

6. Don’t allow the soil to dry out, the soil should be kept moist at all times not waterlogged, the moist soil will help in promoting root growth. Germination should take place in about 30 days.

Sea garpes growth time

A sea grape tree can take anywhere from 2-3 years before they reach maturity, with a hand pruner and lopper shears you can keep sea grapes at the desired height and shape but if left unchecked can grow to be 25-30 ft.

How to harvest sea grapes

The time of year to harvest sea gapes is during the fall season, this is when sea grapes turn from lime green to a dark purple, the medium size dark purple ones are more preferred when harvesting although I have tasted some really sweet ones that were small and purple and others which had a little green in them. Ripe sea grapes will usually fall from the tree easily.

    • Hello Aubin, thanks so much for stopping by, once your tree is mature you can look for sea grapes to appear around August through October, Hopes this helps. Happy Gardening.

  2. Thank you very much for helping me with this. I had been choosing stems that were healthy. That is obvious. But I had not been paying much attention to having my sharp hand pruner be completely clean to remove the stems. I will try cleaning when I do it again! It seems simple but this has helped me!
