|There are two things I have been wondering about.
1) Can I grow strawberries as perennials in Hawaii in the ground?
2) Can I grow grapes in the yard for many years?
|Strawberries do grow in Hawaii -- up high where the air is clean and cold. If you live in Waimea on the Big Island or Upcountry Maui, a vine-ripe, picked-today strawberry is always a possibility. Strawberries are happy with cold nights --to keep the vigor in the plant and extend its production -- but they also thrive on sunny days that develop the sugars in the fruit. The ideal temperatures are low 70s in daytime, low 50s at night. I'm afraid Honolulu is not the place to try and grow strawberries, though.
I'm afraid the above is true with grapes, as well. They need to grow in a higher elevation than Honolulu provides in order to develop fruits. But the vines will grow for you if you're looking for shade for an arbor or gazebo.
Best wishes with your garden!
