Q.How to grow coffee plant outdoors
How many need water? What kind of soil? Can I to leave coffee plant outdoors for winter?

Coffee plants cannot take temperatures below freezing and will not do well in temperatures that stay consistently below 65 F. Therefore, you cannot leave the coffee plant outdoors during the winter. During the summer months you can set your coffee plant outside in a location with filtered sunlight. While the coffee plant is outdoors, the ideal night temperatures are lower to mid 60s with day temperatures at 70 degrees or higher. In terms of watering, you will want to keep the soil consistently moist, but never damp/soggy so you will water it when the soil is just about dry to the touch. The soil you pot your plant in should be rich, well-draining soil.
