Dutch Bulbs in Mexico
I was thinking of taking some Dutch bulbs to my relatives in Mexico City. They live in an area of the city which is closer to the mountains since the city is in a valley. The area has winter temperatures of upper 30s at night and 60s at day and summer only gets up to 85 and 50s at night. Winter gets little rain, spring is hot and dry, summer is rainy and mild and autumn is mild with avg. rain. So their zone is 9b. Could they successfully grow Dutch bulbs such as tulips, daffodils, hyacinths, and crocus? Take in to consideration they'd amend the soil with coarse sand for drainage and protect them from animals with cages and repellents. With care such as fertilization and division could these grow as perennials?
