Tips and Warnings. Related Articles. Article Summary. Part 1. Choose a type of hibiscus to plant. Hibiscus come in a variety of colors and appearances, but what is more important than choosing the look of a hibiscus plant, is finding one that will thrive in your local environment. There are two general types of hibiscus bushes: tropical and hardy. Hardy hibiscus are hybrids that have been developed to grow in cold areas whose temperatures may drop below freezing in the winter.
Tropical hibiscus have more plentiful blooms, but they die off after only days. They are typically in shades of pink, peach, and purple.
They generally come in hues of red, white, and pink. As with most flowering plants, there are three general ways you can grow your hibiscus: from seed, from a transplant, or from a cutting. Growing hibiscus from seed can be fun, because you can create an entirely new cultivar by crossing two existing varieties of hibiscus.
On the other hand, growing from seed requires the most work, and may not be successful. Growing from cuttings is the least likely to be successful, as it requires very specific conditions in order to work out. You may not have much variety of choice when growing from a pre-existing potted plant, as nurseries typically only carry a few varieties of hibiscus seedlings or transplants.
Know when to plant. As heat-lovers, hibiscus should not be planted until well after the winter season has ended. If the temperature drops to 55 degrees, the plant will stop growing. If it drops to 45 degrees or colder, the plant will die. This is less true for hardy varieties of hibiscus, but is still an important reminder of the necessity of heat for these plants.
Call your local agricultural extension for specific advice on when to plant in your area. Choose the perfect location.
Choose a location in your garden that gets hours of direct sunlight a day, and ambient sunlight for the rest of the time.
Typically this would be on the west or south side of your garden. The hibiscus can be shaded by larger trees if necessary, but will need space to spread out, as they may eventually take up two or three times the space of their original size. Some hibiscus plants have lived over 40 years, meaning that you could be dealing with a very large bush. Make sure you find a permanent location for your hibiscus to start.
On the other hand, avoid a location that is primarily sand. To do this, dig a hole, pour a gallon of water in it, if the water doesn't disappear within an hour, then amend the soil to deal with the extra clay in it. If the water drains too quickly when you pour it in, then consider adding come clay. Amend the soil. Hibiscus have picky soil requirements, so it is worth it to take time to amend the soil prior to planting them. Test the pH of your garden soil; hibiscus prefer acidic soil, so anything above 6.
Mix in a garden compost several weeks or months, if you have the time prior to planting. If the pH of your soil is too basic, add in peat moss to balance it out. Part 2. Dig your holes. Use a shovel or gardening trowel to prepare your holes for planting. Each hole for a single plant or hibiscus seed should be as deep as the roots go, and at least twice, if not three times, as wide. I am in zone 5. Hi Nancy, You can absolutely plant hibiscus in the fall. We recommend purchasing one of the hardy varieties that we mention in the article above!
However, too much of a good thing can also be bad! Hi I have a white webby mass with little white bugs on my hibiscus plant. I've sprayed with hose tried been oil and pruned but they kept coming back every year. What is this a what do I do to get rid of them. They kill my leaves. It sounds like you could be dealing with either spider mites, whiteflies, or mealybugs, which are all common insect pests. For this reason, your best bet is to focus on keeping damage to a minimum instead of on outright prevention.
The things you are already doing are good tactics. Keep a close eye on the plants around the time when you first start seeing the bugs and then prune off effected areas, and use neem oil as well. This can be found at a local garden center or online. Just wanted to tell you I have a beautiful hibiscus plant that has already given me blooms.
It still has more buds ready to burst. What an awesome plant this is. I have a lot of hibiscus and they seed themselves. I have never cut them back, what is the purpose? You can cut them to a globe shape if you want another look. I did that this year and they are beautiful. Also you can tie them together if planted close and you will have a bigger globe. I love this plant its so hardy. My hibiscus plants were beautiful up until August Now they form the little pods that look they are going to make blooms but the turn a very pale yellow and fall off before turning into a flower.
Also I have one plant that all the leaves are turning yellow Thank you for your help. It goes from one Hibiscus another. I have lost six hibiscus in one season hope you can help I love hibiscus. Females lay eggs on the leaves, the hatch and start eating on the underside, usually in July.
The University of Maryland suggests this: Handpick larvae or prune out affected tissue and destroy. If the population is too big, or the plant is too tall to hand-pick, treat with Conserve, an insect control produce. I live in North Carolina zone7 and have the exact hibiscus as pictured. I cut it to the ground every year and it comes back perfectly. I'm surprised not to see the Hibiscus Sawfly listed as a pest in this article. This pest is a major problem in my area, and if not treated can wreak much more havoc than the pests listed.
Perennial hibiscus bloom late in the season here in the northern latitudes, August through now, early September. Mine will be done in about a week. I always clip off the dried husks that held the flower, never saw a rebloom, not enough time in the season.
Still, it's a stunning and beautiful addition to any garden if you have the room. Mine is the centerpiece. A late starter in the spring, but fills in fast by June. It's about 4' X 4' so be certain you can adjust for the full grown size, reached in about 3 years. I cut it to about 4 inches in November. I like the sticks and few dried leaves for Halloween! End of March, I cut the remaining 4 inches to the ground. Usually the sticks just break off easily. It's 9 years old now. Full sun is best.
If it seems extra slow to get growing in the spring, give it a good drink for a few days in a row and it will take off. We have a large beautiful --until recently--red hibiscus.
It is about 4 years old. We now have a stick bush. WHAT happened. What should we do.
