подскажите пожалуйста, насколько реально круглогодичное выращивание кактусов в открытом грунте (или в горшках, но вне помещения) в условиях полу-горного Крыма (район Симферополя)??
какие дополнительные условия лучше создать и какой уход может понадобиться, например, в зимнее время?
прежде всего интересуют трихоцереусы, эхинокактусы, миртилокактусы, агавы..
спасибо
