Transplanting has varying degrees of success. Plants don't like to be moved, and some are more intolerant of it than others. Adverse weather conditions and lack of adequate water is the main reason why transplants fail to thrive. However, North Florida offers one of the best climates for transplanting. Because the weather is mild and there's plenty of rain, plants can be transplanted nearly any time of the year.
Harden off indoor plants. Plants should be slowly introduced to a new environment to reduce shock. Begin hardening off indoor plants a week before they are due to be transplanted out of doors. Move them outside into direct sunlight for 2-3 hours for the first day, then bring them inside. Then slowly increase the amount of time so that they spend all day out of doors on the last day of the week.
Prepare the planting area. The soil in North Florida is notoriously poor, so it will likely need to be amended to grow healthy plants. Hand or roto till the area to a depth of 1 foot then add a 4 inch layer of potting soil followed by a 4-inch layer of aged compost to create a raised planting bed.
Dig a hole(s) that is slightly larger than the container that your plant(s) is currently growing in.
Remove the plant from its current container. The best way to do this is to water the plant then tap the sides of the container to loosen the soil. Then gently pull the plant out of the soil by the base of its stem. Take care not to damage the roots.
Plant each plant in the hole so that it it sits at the same depth as when it was in its container.
Mix 1 to 2 tablespoons of 10-50-10 fertilizer into one gallon of water.
Water the transplanted plants slowly to give the water an opportunity to thoroughly saturate the soil. Continue to keep the soil moist by watering it regularly with plain water.
Provide your plants with shade. The North Florida sun can be intense and too much for newly transplanted plants to handle. Use an umbrella, palm leaf or any other tool to provide your saplings with shade for the first 5 days that they are in the ground.
