09 Feb 15, Clifford Foy (USA - Zone 12b climate): two questions. Which variety of onions and garlic are best for growth in Puerto Rico. were can I buy them and expect to get them to Puerto Rico. Many say they are not to be shipped to Puerto Rico(price for living in the colony). Thanks, C.Foy

28 Nov 20, Sandra Garcia (USA - Zone 10b climate): Try Baker Creek; I get all my seeds there, I also use Trade Winds Fruit, Baker Creek has videos and they tell you the temperature that the plant can grow in, but you need to research each seed type to see what weather it grows well in. Read the reviews for the plants to see what others say about it. You can definitely grow everything all year round! Good luck
