The reproductive phase of a sunflower begins in June and ends in July or August, and the blooming phase lasts around 20 days. You can tell the seeds are ripening when the back of the sunflower head turns yellow. The bud may initially have a star-like appearance, but once the reproductive phase is complete, you’ll see your bud transform into the tall-stemmed, yellow-bloomed plant you know so well.

Costa Rica Food Exports
The top three food exports of Costa Rica are pineapples, bananas and coffee.
It was interesting to see blue covers on the bananas. The use of a banana fruit blue ripening bag can improve the quality of the fruit as well as increase the yield, and in many case reduce the ripening time. The ripening fruit gives off a gas that in turn speeds up the ripening of remaining fruit. Covers also help to protect the fruit against insects and other animals.
