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 :

If a rapid response is needed to correct a chlorotic condition, a foliar spray with iron sulfate or iron chelate solution may be applied when the tree is in full leaf. A rate of five pounds of iron sulfate in 100 gallons of water (2.5 ounces iron sulfate in three gallons water) is recommended.
Iron Chlorosis Treatment

These are: 1) soil application of elemental sulfur combined with ferrous (iron) sulfate; 2) soil application of iron chelates; 3) foliar sprays containing ferrous sulfate or chelated iron; or 4) trunk injection of ferric ammonium citrate or iron sulfate (trees only).

Chlorosis in pin oaks is usually due to a deficiency of iron in the leaves. Iron is important for chlorophyll synthesis in plants, so when it is deficient, leaves cannot make chlorophyll, resulting in a yellow appearance.
An effective means of supplying iron deficient plants with supplemental iron is by spraying fertilizer on the plant leaves. An inexpensive and commonly used material for this purpose is ferrous sulfate (FeSO4. 2H2O). Mix 1 to 2 oz of ferrous sulfate in 1 gallon of water.
Short-Term solutions

Soil fertilization treatments produce the best results, but are usually the slowest to respond. Soil treatment is best done in early spring through mid-May. For mildly chlorotic trees, fertilize with a nitrogen or nitrogen- and sulfur-based fertilizer.

Ferrous sulfate or chelated iron solutions can be sprayed directly onto leaves of affected trees. These treatments generally provide very quick results and green-up often is seen within two weeks.
Chlorosis may also be caused by root damage due to poor drainage, overwatering, drought or excess chemical fertilizers. Once you eliminate these causal conditions, the leaves and stems of your plants should turn green again.
A yellow leaf has lost its chlorophyll (pigment) and it can`t turn green again even after you correct the problem. Don`t worry, if the plant regains its health, it`s possible that new leaves will fill in during the next growing season. Growing plants is always a matter of patience.
Pin oak can survive and thrive without supplemental fertilization. But if you wish to give them extra nutrients you can add some of 12-6-6 (N-P-K) fertilizer. this has more of a ratio of nitrogen than phosphorus and potassium. Also, consider the natural environment of oaks.
Chlorosis may also be caused by root damage due to poor drainage, overwatering, drought or excess chemical fertilizers. Once you eliminate these causal conditions, the leaves and stems of your plants should turn green again.
Iron chlorosis is a problem that stems from the soil. Although it requires a soil test and specific amendments to correct, it`s completely solvable. But don`t expect immediate results. It takes 12 months for the amendments to mix into the soil and begin to relieve the chlorosis.

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
