Have you ever had a shrub or tree that has slowly declined to the point where leaves began to fall off or the plant eventually died? Often when plants have a slow decline you should consider taking a look at the roots and soil. Soil problems such as excessively high or low pH can lead to stressed plants, which may allow disease pathogens to take hold. A common disease pathogen that can attack trees and shrubs is Armillaria Root Rot. A recent sample sent to the PDIC confirmed Armillaria Root Rot on a “Knockout Rose”. Unfortunately little can be done to completely control this root rot as the pathogen can persist in the soil in infected plant parts. 
Often white fan shaped mycelium just under the bark of a tree or shrub can be used to identify this disease. Occasionally, honey colored mushrooms will also grow at the base of the plant. No fungicides are labeled for control of Armillaria Root Rot, but careful removal of infected plants and surrounding soil may help limit spread. If you suspect a plant that may have a root rot, consider sending a sample to the PDIC to confirm. Giant Vegetables Have you ever dreamed of growing 4-pound tomatoes, or perhaps a 1200-pound pumpkin, or maybe a 200-pound watermelon? Well, why not, its fun. This year in the Extension demonstration garden giant pumpkins and watermelons are a new feature. Unlike traditional gardening where quantity of fruit is of greatest concern, giant vegetable growing is all about one thing, SIZE. Giant vegetables are not that difficult to grow but do require extra attention. The first thing to consider when growing giant vegetables is to create a quality soil in which the plants can grow and to provide the best site conditions for growth. A deep, well-drained soil with lots of organic matter and a site that receives at least 6 hours of sunlight is required (8-10 hours is best). Also, optimum pH and fertility levels need to be maintained with a timely soil test. A second consideration for large vegetables is to choose the right genetics for giant plants. Giant vegetables seeds can be found in many seed catalogs and from online suppliers and include plants like Dill’s Atlantic Giant (pumpkin), Carolina Cross (watermelon), and Big Zac’s (tomato). Once seeds have been chosen, you will need to insure that those seeds get a good start, most likely through transplant production. Once plants have been placed in the garden, close attention must be given to the care and protection of these plants. Insect and disease control are a priority as these pests could lead to less than optimum growth conditions. Also consider removing all but one or two fruits that are produced on your plants, as this will help ensure that all the plants energy go into these few fruits. Shade protection will also help pumpkins and watermelons, as the shade will prevent early hardening of the fruit skin under hot sunny conditions. Regular watering and fertilizing is also required as most fruits contain large quantities of water and nutrients maintain active growth of plants and fruits. Finally, at the end of the season when your giant vegetable is at its greatest size, its time to cut it loose and take it to the County Fair to showcase your success.
