Ipomoea is a group of perennial or annual vines as well as evergreen shrubs and perennials.The vines require support, full sun and humus rich soil. They are frost tender at 45-50F. Red spider mite and whitefly can occasionally cause problems. Can be propagated by spring seed or summer cuttings. They are not related to Convolvus arvensis the hard to eradicate vine also known as Morning Glory or Bindweed. I.batatas a tuberous perennial climber blooms into trumpet-shaped lavender to pale purple flowers to 1 inch across. Sometimes the tubes are white but mostly darker than the flowers. Chartreuse leaves make for an attactive display in your garden.

FertilizingHow-to : Fertilization for Annuals and Perennials
Annuals and perennials may be fertilized using: 1.water-soluble, quick release fertilizers; 2. temperature controlled slow-release fertilizers; or 3. organic fertilizers such as fish emulsion. Water soluble fertilizers are generally used every two weeks during the growing season or per label instructions. Controlled, slow-release fertilizers are worked into the soil ususally only once during the growing season or per label directions. For organic fertilizers such as fish emulsion, follow label directions as they may vary per product.
LightConditions : Full Sun
Full Sun is defined as exposure to more than 6 hours of continuous, direct sun per day.
WateringConditions : Moist and Well Drained
Moist and well drained means exactly what it sounds like. Soil is moist without being soggy because the texture of the soil allows excess moisture to drain away. Most plants like about 1 inch of water per week. Amending your soil with compost will help improve texture and water holding or draining capacity. A 3 inch layer of mulch will help to maintain soil moisture and studies have shown that mulched plants grow faster than non-mulched plants.
PlantingHow-to : Planting Vines & Climbers
Choose the planting site for your climber carefully: its long flexible stems may need some shelter, but planting right next to a wall might keep it from the sun or water it needs. Make sure that there's room for the climber to grow when it gets tall, and remember that it will grow towards the sun unless carefully trained. Be sure you will be able to manage the plant once it becomes tall, or that if it has a mind of its own, it won't become a problem.
If planting in a container, follow the same guidelines. Plan ahead by adding a trellis to the pot, especially if the container will not be positioned where a support for the vine is not readily available. It is possible for vines and climbers to ramble on the ground or cascade over walls too. Clematis and Roses actually work quite well this way.
How-to : Planting Shrubs
Dig a hole twice the size of the root ball and deep enough to plant at the same level the shrub was in the container. If soil is poor, dig hole even wider and fill with a mixture half original soil and half compost or soil amendment.
If shrub is bare-root, look for a discoloration somewhere near the base; this mark is likely where the soil line was. If soil is too sandy or too clayey, add organic matter. This will help with both drainage and water holding capacity. Fill soil, firming just enough to support shrub. Finish by mulching and watering well.
ProblemsPest : Spider Mites
Spider mites are small, 8 legged, spider-like creatures which thrive in hot, dry conditions (like heated houses). Spider mites feed with piercing mouth parts, which cause plants to appear yellow and stippled. Leaf drop and plant death can occur with heavy infestations. Spider mites can multiply quickly, as a female can lay up to 200 eggs in a life span of 30 days. They also produce a web which can cover infested leaves and flowers.
Prevention and Control: Keep weeds down and remove infested plants. Dry air seems to worsen the problem, so make sure plants are regularly watered, especially those preferring high humidity such as tropicals, citrus, or tomatoes. Always check new plants prior to bringing them home from the garden center or nursery. Take advantage of natural enemies such as ladybug larvae. If a miticide is recommended by your local garden center professional or county Cooperative Extension office, read and follow all label directions. Concentrate your efforts on the undersides of the leaves as that is where spider mites generally live.
Pest : Whiteflies
Whiteflies are small, winged insects that look like tiny moths, which attack many types of plants. The flying adult stage prefers the underside of leaves to feed and breed. Whiteflies can multiply quickly as a female can lay up to 500 eggs in a life span of 2 months. If a plant is infested with whiteflies, you will see a cloud of fleeing insects when the plant is disturbed. Whiteflies can weaken a plant, eventually leading to plant death if they are not checked. They can transmit many harmful plant viruses. They also produce a sweet substance called honeydew (coveted by ants) which can lead to an unattractive black surface fungal growth called sooty mold.
Possible controls: keep weeds down; use screening in windows to keep them out; remove infested plants away from non-infested plants; use a reflective mulch (aluminum foil) under plants (this repels whiteflies); trap with yellow sticky cards, apply labeled pesticides; encourage natural enemies such as parasitic wasps in the garden; and sometimes a good steady shower of water will wash them off the plant.
MiscellaneousGlossary : Arbors, Trellises, Pergolas
Arbors, trellises, and pergolas provide vines and climbers the support needed for their growth habit. These can be used as features or accents in a garden to add height, to provide shade, or as a transitional element from one area of the garden to another. Common materials for these structures include wood, metal, and plastic. Select according to the style of your garden and the amount of upkeep required. Painted, wooden structures will be higher maintenance, whereas a rust-proof metal structure will require less maintenance and last longer.
Glossary : Backdrop
Backdrop is the term used to describe a plant or architectural element that is relatively neutral in appearance, that serves as a background for other plants. Backdrop plants are often taller, have dark or medium green leaves, and often of medium texture. However, this is not always the case. For a tropical effect, or to make a space more intimate, use a backdrop with coarse textured foliage. To make a space appear larger, use a small to medium textured leaf plant that is dark green.
Glossary : Vine
Vine: a plant with a flexible stem that grows either along the ground or climbs by suckers, twining, or tendrils.
