Ipomoea

( eye - poh - MEE - uh )

At-A-Glance Information

This genus of ornamental (and one edible) flowering vines needs full sun and moderate to regular water, and is commonly known as Morning Glory. There are many varieties in this genus, including edibles to container plants to those that twist and climb, providing great trellis coverage. Morning Glory vines can be used as climbing plants on arbors or other structures or as sprawling groundcovers. Take care when planting these in your garden as some species' plant parts are toxic to humans and pets if ingested, and many species are considered highly invasive in certain regions.

Caring for Ipomoea

Take care when planting these in your garden as some species' plant parts are toxic to humans and pets if ingested. Sow seeds in place after the danger of frost has passed, or begin seeds indoors. Set out plants 6-8 inches apart once they are ready to be transplanted to the garden. Alternatively, grow the plant from a seedling purchased at a nursery or garden center. Make sure to plant these vines in full sun to partial shade. They should ideally be receiving between 4 and 6 hours of direct light each day, and will flower and produce the best foliage the more sun they get. Some afternoon protection from sun is needed in particularly hot areas to avoid over-stressing the plant or leaf sunburn. They prefer well-draining soil with a pH of between 6.0 and 7.0. If local soils are compacted, do not drain well, or are particularly poor in nutrients, make sure to amend the planting area with plenty of organic matter or compost before installing. Apply a thick layer of mulch around the base of the plant after installation, ensuring that mulch stays at least a few inches away from the stems. This will increase soil moisture retention, suppress weed growth, and maintain a constant soil temperature.

Keep the soil moist while plants establish a strong root system; mature plants are considered somewhat drought-tolerant, but they do appreciate consistent moisture during the growth and flowering season. Fertilize yearly in early springtime with an application of 2 inches of compost around the base of plants. Pull mulch back before applying, work the compost gently into the soil a bit, water it in, and then replace mulch. Foliage can be trimmed back at any time of the year to control growth and remove dead, damaged and diseased stems and leaves. Doing so will keep the plant in its healthiest and most attractive form. Pinch young plants to encourage a bushy habit to form. Morning Glories can survive in the landscape for decades in ideal growing conditions. Where they are grown as annuals, they are pulled and composted at the end of the growing season and re-grown in the next.

Harvesting Ipomoea
Ipomoea batatas, or Sweet Potato Vine, plants are commonly grown for their foliage, but can also be grown for their edible storage roots. They take about 90-120 days to reach harvestable size, and are typically harvested once foliage begins to yellow and die back for the season. To avoid tuber injury, harvest just before the first frost of the fall/winter. These plants produce on average about 2-5 pounds of potatoes, but in ideal growing conditions can produce up to 11 pounds. A few days before harvesting, cut back the leafy above-ground vines to encourage a tougher skin to form, which will help extend storage time and decrease bruising. When harvesting, carefully dig around the exterior of the plant, using a trowel or garden fork to gently lift. Once plants are loosened, they may be able to be pulled up by the foliage. Handle roots gently to avoid bruising them, and remove a majority of the dirt and debris. Do not wash roots, as moisture will encourage decay. Set them out for 2-3 hours in a sunny, breezy area. Then, air dry the tubers in a warm (80-85 degrees Fahrenheit), sunny location for between 7 and 14 days. This will convert starches into natural sugars and heal any minor cuts. Once cured, store the tubers in a cool, dark, well-ventilated space. They will stay for between 4 and 6 months if stored properly.

Propagation

Ipomoea can be propagated either by using cuttings or from seed. To ensure that your propagated plant will have the exact same qualities and characteristics as the parent plant, use the cutting method. If you would like to experiment and see what plant you can grow from seed, just keep in mind that it will not necessarily be the same as the parent plant. To propagate your Morning Glory Vine, follow the instructions below:

Propagating Ipomoea by Cutting

Gather your materials. You'll need a clean, sanitized, sharp pair of garden shears, rooting hormone, a pencil, and a 3-inch pot filled with well-draining compost or other organic material. A good substrate for propagation of cuttings is a light blend of 1/3 pasteurized soil or compost, 1/3 sand, vermiculite or perlite, and 1/3 coconut coir or peat moss.
In spring or early summertime, choose the plant that you'd like to propagate. Ensure that this plant has had a good watering the night before, as this will improve the chances your cutting will take root. Cut one or more 6 inch portion(s) of the end of a non-blooming branch and strip the leaves off of the lower half. Make a hole in your planting medium by pushing your pencil into the soil. Dip the end of the stem in rooting hormone, and plant it in your pot. Fill in soil around the cutting to support it, but do not pack it down too much.
Moisten with water, and ensure that the pot has good drainage. Your pot should be kept in warm, sunny conditions indoors (and not in direct sunlight). Water whenever your soil is dry under the top layer. After about four to six weeks have passed, your cutting should be rooted. When you notice new growth, you'll know you have roots.
Keep your new plant in an area with bright light (though not direct sunlight) and temperatures between 55 and 70 degrees Fahrenheit. Ensure that the soil stays moist, but not wet, until the next spring, when you can transplant it to its new home. Ensure that the last frost of the year has occurred before doing this, as it can seriously damage your new plant.

Propagating Ipomoea by Seed

Keep in mind that the plant you get from seed will not necessarily mimic all of the characteristics of the parent plant. To propagate by seed, you will need a paper bag, a pot or tray filled with well-draining compost or other organic material, a spray bottle and a fork. The best potting medium for seed germination is a light blend of 1/3 pasteurized soil or compost, 1/3 sand, vermiculite or perlite, and 1/3 coconut coir or peat moss.
Harvest your seeds. The seed pods on Ipomoea plants are pretty easy to spot, they're left behind after flowers have faded. Once they have dried out and begun to split open, you can harvest the seeds inside. Cut them off of the plant, placing them in a paper bag. Harvest as many as you can, and place the paper bag in a dry, cool, dark area. They will begin to split open and release the seeds contained inside. Once they have been released, take them out of the bag and put them in a container so you can work with them.
Water your prepared seed tray or pot filled with soil, and ensure that good drainage is occurring. Place your seeds in your prepared pot or seed tray about a quarter inch to a half-inch under the soil surface. Cover them with soil and water with your spray bottle. Place your tray of seeds in a warm area that receives bright, indirect light. A greenhouse is the most ideal climate, but a planting tray inside a window will do as well. Germination usually takes 7-14 days from sowing. Once you begin to see seedlings sprout and they are able to be handled, transplant them to their own individual 3-inch pots, filled with the same potting medium as described in Step 1. Loosen the seedlings from the potting medium by digging down with the tines of your fork about an inch and a half, gently working the seedling up until it is out. Then, replant the seedling in its individual pot.
Keep the seedling's potting medium moist, but not wet, by spraying the soil with your spray bottle. Keep your new plant in an area with bright light (though not direct sunlight) and temperatures between 55 and 70 degrees Fahrenheit. Ensure that the soil stays moist, but not wet, until the next spring (after the danger of frost has passed), when you can transplant it to its new home.

Morning Glory seed pods hold many seeds, and dry up and turn brown when mature.

Ipomoea seeds are typically relatively small, and can be black to brown or light tan in color.
