Changing Garden Soil pH
The correct pH is critical for garden success. Retired UT Extension Agent Mike Dennison explains that most plants like a soil pH between 5.8 and 6.2. If you are outside this range, you will need to correct the soil pH to allow plants to absorb the nutrients they need. Mike talks about the different products to raise and lower pH. To raise pH lime is used. To lower pH sulfur is used. Mike has a few blueberry plants that require very acid soils so he shows how to use a soil test to calculate the amount of sulfur to use. He then applies the sulfur.

IPM (Integrated Pest Management)
The goal of IPM is to focus on the non-chemical control methods of pests. TSU Extension Agent Amy Dismukes explains that often the chemical control method may not be needed. First you need to determine what is going on and recognize and correctly identify the insect or disease damage. Just because you see a problem does not mean it needs to be treated.
IPM includes cultural control like keeping weeds pulled to deny a hiding place for insects. It also includes mechanical solutions like proper pruning or removing fallen plant material. IPM also includes biological controls like beneficial insects. If an insect infestation is minimal and some beneficials are present, the beneficials will likely take care of the problem. The last approach is the chemical approach when the problem has reached a point where immediate control is necessary. When using chemicals use the most targeted, lowest power insecticide you can. After talking about IPM, Amy shows some examples of insect damage that does not require control in the normal way.

Lawn Aeration
UT Extension Agent Booker T. Leigh shows how to aerate your lawn. Aeration is important to loosen compact soil and allow water, air, and fertilizer to reach the roots of the grass. Aeration does not have to be done frequently in a home lawn, every five years is enough. Aeration should be done when the grass is breaking dormancy: April-May for warm season grasses like Bermuda, September for cool season grasses like fescue. Aeration is done a lot like mowing. The aerator travels back and forth across the grass covering the whole lawn. To make sure you covered the lawn you can also aerate it going the other way too. Leave the plugs the aerator pulls out on the lawn. They will break down after a few rain storms.

Deadheading Knockout RosesDeadheading, the practice of removing spent blooms, improves the look of your plants and encourages additional flowering.
Understanding Deadheading Knock Out roses, known for their prolific blooming throughout the season, benefit from deadheading. As blooms age and wither, the plant puts energy into creating seeds not flowers. Removing these spent blooms encourages the plant to put more energy into new flowers. When to Deadhead The best time to deadhead Knock Out roses is when the blooms have faded or started to wilt. This is typically after a flush of flowering, which could last for a couple of months. Look for blooms that have turned papery or discolored. Tools and Techniques Before starting, you need to prepare your tools. Use sharp pruners or scissors and sterilize them with rubbing alcohol to prevent the spread of diseases among plants, as roses are particularly susceptible. A clean cut, just above a healthy leaf node encouraged new growth at that node.

Invasive Plants
Non-native invasive plants are a major problem. University of Memphis Director of Landscape Joellen Dimond says invasive plants can cause extinction of native plants and animals and alter habitat. Not all non-native plants are invasive. Invasive plants tend to be vigorous growers that produce many seeds and easily adapt to different environmental conditions – in short, they have the characteristics gardeners want in their plants. Many were brought to this country on purpose as easy to grow garden plants. A good example of this is the Bradford pear which Joellen describes.
Joellen identifies the top 6 invasive plants in the United States: 1. Kudzu 2. Norway Maple 3. Japanese Honeysuckle 4. Purple Loosestrife 5. Japanese Barberry 6. English Ivy Joellen says each state has a list of plants that are invasive in that state. Gardeners should not purchase or plant plants that are on the list in their state.

Inviting Lizards into Your Garden: A Guide to Creating a Habitat
Lizards can be valuable helpers in the garden, and attracting them is easier than you might think. Mary Schmidt from Lichterman Nature Center in Memphis, Tennessee says creating a suitable habitat is key, focusing on elements like food, water, shelter, and space. Since most lizards are insectivores, incorporating native plants to attract insects is a great start. Because lizards are cold-blooded, providing spots for them to bask in the sun or seek shelter from its heat, such as rocks or hiding spots like snag piles, helps them regulate their body temperature. >>Read More

Repotting Grocery Store Orchids
Repot your grocery store orchid to keep it alive and healthy. Orchid expert Randall Bayer shows how. Orchids live on trees in tropical areas. Their roots absorb water from the almost daily rains in those areas. The tree bark where they are growing then quickly dries out. The orchids store the water in special structures called pseudo bulbs or in their leaves. Orchids for sale in stores are usually potted in sphagnum peat moss. The peat moss holds water and does not let the orchid roots dry out between watering like they do in the wild. This means that without special attention, the roots will rot, and the plant will die in a short time. To keep the plant from dying the orchid must be repotted. Randall repots an orchid purchased in a grocery store and shows and explains all the steps.

Native Plants for Xeriscaping in the Southeast U.S.
When you think of Xeriscaping you usually think of cactuses and lots of rocks, but in the South-east United States selecting the right native plants for your landscape will eliminate the need to water even in the hottest summers.
Jessie Munson from Lichterman Nature Center in Memphis, Tennessee says our climate many have wet springs, but in the summer, we can go over a month without rain. This can stress many plants, but native plants are already used to it and can thrive in the heat without water. >>Read More Related Videos: Introduction to Rain Gardens Rain Gardens Building a Rain Barrel Related Resources: Xeriscaping: Creative Landscaping Creating a Water-Wise Landscape |

Daylily Basics
Daylilies are forgiving plants that add color to the garden. It is the favorite flower of UT Extension Agent Lucas Holman. There are over 60,000 hybrids of daylily, but there are two main distinct types: diploid and tetraploid – which refers to the number of chromosomes. Daylilies need full sun. They do well in many kinds of soil from heavy to loose. Lucas briefly talks about how to cross different plants and create new hybrids. He also talks about how to divide the plants, which is best done in the spring. If you are interested in growing daylilies Lucas recommends joining the American Hemerocallis Society which is the national daylily growing organization.

Planting Potatoes
Planting potatoes can be a rewarding endeavor for gardeners, offering the satisfaction of harvesting your own crop. UT Extension Area Specialist Walter Battle walks through the steps involved in growing potatoes, from choosing the right time to harvest and storage considerations.
Choosing the Right Time to Plant Potatoes can be planted early in the spring when the days are warmer, but there is still the chance for a light frost. Potatoes can tolerate light frost, making them resilient to cooler temperatures. In the Mid-South region, March is typically considered an ideal time to plant potatoes. However, depending on the weather, planting can extend into late February or early April. For those aiming for a fall harvest, planting in late July, or about 3 months before frost, is also an option. Selecting Seed Potatoes When selecting potatoes for planting, avoid using store-bought varieties, as they are often treated to prevent sprouting. Instead, opt for seed potatoes, which can be found at farm supply stores. Look for potatoes with well-defined sprouts or "eyes." Planting Before planting, ensure the soil is well-tilled. Potatoes thrive in loose, well-draining soil. Begin by digging a trench approximately six inches deep. This depth allows for proper root development and facilitates hilling, a key step in potato cultivation. Plant them with the eyes facing upward, spaced approximately one foot apart within the trench. Once the seed potatoes are in place, cover them with soil, leaving them approximately six inches below the surface. As the potato plants grow, periodically mound soil around the stems to prevent greening and encourage large tuber development. This process, known as hilling, helps protect the developing potatoes from exposure to sunlight. Maintenance and Harvesting Potatoes require minimal maintenance beyond regular watering and hilling. After approximately 90 days, the potato plants will begin to yellow and wither, indicating that they are ready for harvest. Carefully dig up the potatoes, being cautious not to damage them. Allow the harvested potatoes to cure in a cool, dark location for two weeks before storage. Pest and Disease Management While potatoes are relatively low-maintenance, they are susceptible to certain pests and diseases. Common issues include potato beetles and scab. Potato beetles can be controlled – if desired – by insecticides. Selecting scab-resistant potato varieties can help mitigate the risk of disease. Additionally, planting potatoes previously uncultivated soil can increase the likelihood of infestation by wireworms. Also, proper crop rotation is important; don’t plant potatoes where potatoes or corn was grown the year before. Recommended Potato Varieties Several potato varieties are well-suited for home cultivation. Classic choices include Kennebec for white potatoes, Red Norland for red potatoes, and Yukon Gold for golden potatoes. For those looking to experiment, Adirondack Blue offers a unique twist with its vibrant blue flesh.

Frogs and Toads
Mary Schmidt from Lichterman Nature Center talks about frogs and toads and why you want them in your garden. They are amphibians that are tied to water. They lay their eggs in the water and have part of their life cycle there too. The bumps or warts on toads are a protection. The bumps contain glands that secrete a toxin. Toads are a kind of frog. Mary has several frogs and toads with her to demonstrate the differences. Frogs like the bullfrog have long back legs and leap. True toads have dry rough skin and shorter stubbier legs to hop. She also brought a tree frog and spadefoot toad.
Frogs and toads are beneficial in several ways. The most obvious is that they eat a lot of insects. Also, frogs and toads can absorb things through their skin, so they can be an indicator that you have problems in your yard or garden. To attract frogs and toads to your garden you need to provide habitat they like. They need water and moisture. You can also provide places for toads to hide. Mary shows how to make a toad abode with a flowerpot and a couple of rocks. Toads look for movement to find insects to eat. When they eat they pull their eyes into their head to help push the food down their throat. Bull frogs eat anything they can fit into their mouth including insects, other frogs, and even birds. Mary feeds some mealworms to the toads to show how they eat. Related Videos: My toad abodes only attract black widow spiders. How do I attract toads?

Plant Societies and Garden Clubs
Former Memphis Horticultural Society President Suzy Askew talks about plant societies and garden clubs. The Memphis Horticultural Society is the umbrella organization over many different plant societies in the Mid-South. The Memphis Horticultural Society brings in monthly guest lecturers from around the country to talk on different topics. Under the Memphis Horticultural Society are many different plant societies that specialize in a specific plant.
Local garden clubs are usually affiliated with one of two large organizations: National Garden Clubs, or Garden Club of America. The large national organizations have programs concentrating on various areas like flower arranging, gardening, environmental and conservation, landscape design, and scholarship. If you would like to join a garden club, Suzy recommends that you visit several different clubs and see where your interest lies. You can attend many of the clubs without becoming a member for a small admission fee. Also, some clubs do not require more than annual dues. Don’t worry about not knowing enough to become a member. Suzy is a member of several plant societies and she does not consider herself an expert. She says she learns a little more every time she goes. Another option is to become a master gardener. This is a course offered by the Extension Service. There is a fee and required service hours, but you learn many things about plants.

How To Support Growing Tomato Plants
There are many options for supporting tomato plants in your garden. Gardener Peter Richards shows several methods he has tried and talks about what he likes and does not like about each one. He says that the traditional wire tomato cages do not work, instead you need a sturdier structure. He talks about and shows the pros and cons of heavy tomato cages, the Florida weave, livestock panel platform, tying the plants to a pole and tying them up with string. His personal favorite is to prune the tomatoes into a vine and use string to tie them up. He says this method makes it so you don’t need to spray fungicides nearly as often or at all and the plant will stay blight free for most of the year.

Growing Onions
UT Extension Agent Walter Battle talks about onions. Onions are one of the first vegetables in the ground in the spring. In the Mid-South area around Memphis that is late February or early March. Onions are very frost tolerant so they can be planted long before the last frost. There are two main kinds of onions: spring, bunch, or green onions; and dry onions. You can plant the spring onions about two inches apart because they will not be growing a large bulb before they are used. The dry onions will be forming a bulb and should be planted at least six inches apart to allow room to grow. Green onions are ready for harvest in about 60 days or whenever they look to be the right size for your needs. Dry onions are ready for harvest when the green tops have fallen over (about 100 days or so). Dry onions need to be prepared for storage by drying or curing out of the garden. Walter places the onions on a wire mesh table in his garage for several weeks so they can dry out. Onions like a neutral pH soil but can grow in slightly alkaline to slightly acid soils. Onions do not like wet feet so they should be planted on top a small ridge. Fertilize with a balanced fertilizer. Onions tend to be disease and pest free but there are a few things that can affect them.

Easy Way to Root Cuttings from Annuals
Horticulture Expert Dr. Lelia Kelly shows how to easily and cheaply root cuttings from garden annuals. Every year there are annuals that you hate to see die in the frost. Most of them root easily. You can take cuttings from them in late summer, root them, grow them over the winter and replant them outside the next spring. Lelia demonstrates how to root a coleus. She uses a knife to cut off a terminal (end of a branch). Then she pinches off the leaves that are low on the cutting and pokes the cut end into some moistened potting soil. She them makes a greenhouse for the plant from either a few sticks and a shower cap or a soda bottle. The greenhouse keeps the plant from drying out. After a few weeks, the cutting will have grown some roots. Place the plant with roots in a bright place and water occasionally during the winter. In the spring, you can go plant it back in the garden. Repeat every year to keep your favorite and best performing plants going year after year.

Pruning (Not Murdering) Crape MyrtlesCertified arborist Wes Hopper prunes a Crape Myrtle that has previously been “murdered,” or the top has been chopped off. He starts by removing the low hanging branches and twigs that will poke him as he prunes. He throws the debris away from the tree so he will not trip on it as he is moving around while looking up. This Crape Myrtle tree has multiple stems. Some of those stems are crowded so Wes cuts off several of the stems. This opens up the middle of the tree. Wes likes to use hand pruners whenever possible to avoid damaging the thin bark. Wes removes the epicormic growth, or growth that grows secondary like water sprouts. Epicormic growth is weak and loosely attached to the tree. Wes tries to cut the branches he does not want to grow beyond the branch collar. This will keep them from growing. Wes then prunes the upper canopy of the tree with a pole pruner. He removes the old seed pods. He cuts just above a node to allow for future growth. Finally, he cuts back the suckers around the base of the tree.

Peppers
Master Gardener Tom Mashour talks about peppers. There are hundreds of varieties of peppers available. Pepper heat is rated on the Scoville scale: bell peppers rate as a 0 and the hottest peppers rate at over 1,000,000. Peppers are a member of the nightshade family so they are wind pollinated – the flowers have both male and female parts. Because of this don’t plant hot peppers next to sweet peppers the pollen from the hot pepper can cause the sweet peppers to be hot. Starting peppers is easy but they need to be started inside about two months before they are ready to be planted in the garden. Tom plants his bell peppers in pairs so they can shade each other and prevent sun scald on the fruit.
Peppers need at least 6 hours of sunlight per day. Peppers need to be staked for support. They like a damp soil and a balanced fertilizer. If you limit the plant to three or four peppers at a time the peppers will be good size. As peppers turn red they get sweeter. There is a point where the pepper is red but with a little green where it is sweet but not mushy.

Planting Myths
UT Extension Horticulture Specialist Carol Reese gives some common planting myths and corrects them.
Myth: Soil amendments are necessary. Fact: Often adding amendments changes the soil structure and may not help the plant. If you add amendments, do it to the whole area around the plant, not just the planting hole Myth: Add hormones and root stimulator. Fact: There is no scientific evidence that they help. Also, don’t fertilize woody plants for at least the first year. Myth: Container plants are better than ball and burlap plants. Fact: Container plants have problems with girdling roots. Myth: You can leave the burlap on the root ball. Fact: You want the roots to get in contact with the native soil as fast as possible so take off all the burlap, wire, etc. Those things will hinder plant growth. Myth: Ball and burlap can only be planted when the plant is dormant. Fact: You can plant anytime but be aware of the higher water requirements in the active growing season especially in the summer. Myth: With ball and burlap, keep the soil together. Fact: Removing all the nursery soil from the root ball has been shown to cause faster plant recovery. Myth: Mulching with raw wood chips steals nutrients from the soil. Fact: Raw wood chips do not rob the soil of nutrients from mature plants. It can be a bad idea of you till it in around young plants. Myth: You must fertilize your shrubs. Fact: You don’t need to fertilize woody plants. They live just fine in the forest with no help. Myth: Manure is a great fertilizer for all plants. Fact: Manure is alkaline. Acid loving plants do not like it because it makes the soil too basic. Research your plant before using it. Myth: Compost tea is great. Fact: How can diluted compost work better than full strength compost? Myth: Some plants keep mosquitoes away. Fact: Mosquitoes do not avoid plants. For example, they will land on citronella with no harm.
