two hibiscus overwintered in garage

Question

I have two hibiscus plants I saved in my garage over the winter. I live in Missouri. I trimmed them all way down so what should I feed them and when can I put them outside?

Answer 1

Move your hibiscus outdoors gradually in the spring when the temperature reaches 45 to 50 F - hibiscus do not tolerate temperatures under 45 F. Nitrogen and high levels of potassium are required by hibiscus. Use a water-soluble fertilizer formulated for hibiscus and feed the plant lightly but regularly. Slow release fertilizer, which lasts up to six weeks, may also be used.
