How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

It is caused by two fungi: Verticillium dahliae and Verticillium albo-atrum. There is no cure for a plant with this fungal infection. Individual branches turn brown and die suddenly due to the fungi blocking the vascular system of the branch, cutting off water and nutrient movement.
Too much water can result in wilted, pale, or yellowing leaves. Established shrubs can tolerate short periods of drought like conditions without damage. Longer periods of dry conditions can cause the leaves and the stems of the lilac to wilt.
The disease starts as brown spots on stems and leaves of young shoots as they develop in early spring. A yellow halo may also be around the spot. Spots become black and grow rapidly, especially during rainy periods.
The main recommendation for controlling lilac blight is to remove all infected tissue. Prune infected branches 10 to 12 inches below the visible infection. To minimize the spread to new cuts, only prune during dry, sunny weather.
Powdery mildew is the most common tree disease to inflict lilac trees. This fungal infection slows the growth of plants, and in some cases may even kill them.
A: Lilac leaves turn brown at the edges from lack of water. Herbicide damage, such 24D, sprayed on the plant will also cause it. This can occur when liquid weed killer is sprayed on the lawn and it drifts on to shrubs. It can also translocate through the soil.
Answer. Curling leaves and crispy edges are often a sign of not enough water. Since it is mid-September, you don`t need to worry about the lilac dying. Just give it a good soaking, at the base and not on the leaves.
If a plant is overwatered, it will likely develop yellow or brown limp, droopy leaves as opposed to dry, crispy leaves (which are a sign of too little water). Wilting leaves combined with wet soil usually mean that root rot has set in and the roots can no longer absorb water.
Bacterial leaf blight is often first noticed in fields as brown areas about 3 to 4 feet in diameter. Leaf symptoms appear as irregular brown spots, often beginning on the leaf margins. Lesions initially have an irregular yellow halo and may appear watersoaked.
The best bacterial blight treatment is spraying lilac bushes in the fall with a fungicide containing copper sulfate. Spray them again in the spring before bud break.
Bacterial blight of lilac, also known as shoot or blossom blight, is caused by the bacterium Pseudomonas syringae pv. syringae. The pathogen is capable of causing damage to all types of lilacs including Japanese, Chinese, Persian and common varieties.
(i) Copper oxychloride @ 3 g/l or copper hydroxide @ 2 g/l or 1% Bordeaux mixture (freshly prepared) will check both bacterial and fungal diseases. Still if any fungal disease is observed then one or two sprays of mancozeb or any other fungicide can be taken.
When you notice a plant with purple leaves rather than the normal green color, it is most likely due to a phosphorus deficiency. All plants need phosphorus (P) in order to create energy, sugars, and nucleic acids. Young plants are more likely to display signs of phosphorus deficiency than older plants.
Grasp one side of the sliced stem and twist backward. Immediately place the cut stems back into the bucket of water. Allow the stems to take up more water in a cool, dark place for another one to two hours. The lilacs will then be ready for arranging, and will last three to four days.

My Z5426 won’t start. When I pull out the choke and turn the key, gas starts leaking out of the exhaust system just before it gets to the muffler. Last time it did start, it ran really rough. So, I turn off the engine and then tried to restart and that’s when I noticed the fuel leak.
ANSWER : Maybe bad fuel, fuel line leaking, flooding of the carburetor, since it did start and ran rough I am assuming that the gas was left set and more then likely this gummed up the carburetor, you will have to clean/rebuild it. If you have a can of carburetor clean you may be able to spray that into there and clean it up, I would not choke it to start it as it sounds like it got/is flooded/ing. Good Luck Tim

Tractor keeps going foreward when bushhoging even with the clutch in.
ANSWER : Do you have an overrunning clutch on your PTO? not sure if I use the right name, but it stops the brush hog from driving your tractor forward from the inertia of the blade. it only allows drive to be transmitted to the brushhog, not from it. Also check your pin in the pto, it may have engaged the sleeve.
