Answer: When nighttime temperatures remain above 50F you can begin acclimating your bougainvillea to the great outdoors. Start by taking it out for a few hours during the daytime and moving it back indoors before nightfall. Allow your plant to stay outdoors for longer and longer periods each day. The whole process will take a week to 10 days. Then allow it to remain outdoors all day and all night. When new growth buds appear along the stems, prune the plant back by about one-third. This will encourage new flowering stems. Regularly pinch and prune the stems during the spring and summer and your plant should bloom all season long. Enjoy!
