images from Becky's Greenhouse Good morning…it was a summer like day on Saturday with the outside temperature near 90 degrees, and we had 90 degrees in the greenhouse. Today is cooler as we have full cloud cover. Inside the greenhouse it is 72 degrees so much nicer to work inside. Outside is 67 degrees. Easier on watering, that is for sure. High today of 74 with a low of 60. Looks like some rain Monday and Tuesday,…I was to have 4-hers here on Monday and Gardeners of North Iowa on Tuesday. I am thinking we need to reschedule both. Enjoy today, work outside in your gardens, and stay safe.
I have two kinds of hardy hibiscus. They are Cherub light pink, and purple heart red/dark foliage. What I was looking in the article was this advice with the plant coming up in the spring. Hibiscus don’t like cold nights, so it might be June before it comes up. I would leave the old stocks from the fall through the winter so you know where the plant is. When it starts to come up then prune off the dead stock. You need to be patient with the hibiscus coming up in the spring. Planting, Growing, and Pruning Hibiscus by Catherine Boeckmann With huge, colorful dinner-plate size flowers, perennial hibiscus plants add a bold, tropical effect to the garden. They are also highly attractive to butterflies and hummingbirds! Here’s how to plant, grow, and care for hibiscus flowers. About Hibiscus There are many types of hibiscus. This growing guide covers perennial hibiscus grown for their strikingly beautiful, big, disc-shaped, hollyhock-like flowers that can measure up to 12 inches across! Perennial hibiscus can grow up to eight feet tall, but dwarf varieties are only two to three feet tall. PLANTING When to Plant Hibiscus Hibiscus can be purchased as young plants from nurseries and are best planted in the spring. Or, they can be rooted from a cutting in the spring. Choosing and Preparing a Planting Site Choose a site that gets full sun; they’ll grow in partial sun but will not flower as well. Hibiscus prefers well-draining soil with plenty of organic matter and neutral to slightly acidic soil. To avoid breakage of the long stems, plant hibiscus where they won’t be exposed to strong winds. How to Plant Hibiscus Plant potted hibiscus plants so that their stems are just at the soil surface. To root a cutting in the spring, cut off a branch 5 to 6 inches long and strip off lower leaves. Plant the cutting in a pot with a mix of three parts sand and one part peat. Roots should form within a few weeks. Transplant the cutting from the pot into the ground. The hibiscus species that die back each year can be spaced 2 to 3 feet apart. Consider the potential height and width (up to 12 feet and 10 feet, respectively) of a mature plant before planting. Water the plants well at the time of planting. GROWING How to Care for Hibiscus Shrubs Hibiscus needs frequent watering, especially when young and new. When watering, do so deeply and thoroughly, drenching the plant. Mulch around the plant to retain moisture and to provide winter protection for the roots. To encourage rebloom, either remove the spent flowers before they form seed heads or prune plants back by one-third after a flush of bloom is finished. Perennial hibiscus will freeze back to the ground each winter; cut old stems to the ground. Hibiscus blooms on new wood (this year’s growth), so pruning is best done in the spring. In early spring, remove dead stems from established plants and apply a balanced fertilizer. Over the growing season, hibiscus can benefit from a fertilizer that is high in potassium, medium to medium-high in nitrogen, and low in phosphorus, as the plant can be sensitive to phosphorus. Mature plants can be divided in the spring, not fall. WIT AND WISDOM The plant has been used to soothe headaches, aching limbs, coughs, and inflammations. Hibiscus tea is made from parts of a different type of hibiscus, Hibiscus sabdariffa—also known as Roselle or Florida Cranberry. It’s native to West Africa but is now grown across Central America, the Caribbean, and even Florida. In Victorian times, giving a hibiscus blossom to a person meant that the giver acknowledged the receiver’s delicate beauty. Clean up all plant debris to avoid fungal diseases which can cause leaf spots. Don’t crowd plants, and keep mulch from touching the stems to avoid blight.
