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 :
What are the lumpy bits on my lemon tree? JANE: These lumps come from a wasp, called a “citrus gall wasp” that has laid its eggs into the branches and stems of the lemon tree and caused a large swellings called a galls. You can either live with it or you cut it right out.
The fungus appears as yellow, dark brown, or black lesions that initially occur on the underside of mature citrus leaves. As the fungus develops, the spots become visible on the leaf top. Citrus tree leaves affected by Greasy Spot will fall prematurely, which adversely affects tree health and yield.
Prune dead and infected branches, which can transfer spores to healthy areas of the tree during rains and waterings. Remove low-hanging, healthy branches to which spores from the ground can more easily attach. If symptoms appear, use a fungicide to treat the problem. Most recommended treatments contain liquid copper.
The fungus thrives when periods of continual wetness saturate decomposing fallen leaves. The fungus will then migrate into trees through splashing rain or wind, and infect living leaves. The symptoms include leaves with yellow spots, raised brownish blisters, and eventually, black lesions that have a greasy appearance.
These `weird little balls` are called galls, which are plant tissue growths caused by exposure to small doses of hormone-like chemicals, which are produced by the gall makers. The gall makers can be many different things – but usually it is insects that cause them.
Citrus canker, caused by the bacterium Xanthomonas citri subsp. citri, affects the leaves, twigs and fruit of citrus plants causing the leaves to drop and unripe fruit to fall to the ground. All types of citrus are affected by the disease. Citrus canker is most severe in hot, wet areas.
Symptoms. Trees infected with citrus blight experience a general decline in health; this includes wilting, die-back, loss of foliage, and the production of smaller/discolored fruits. The infection is not uniform—individual sections of an affected plant will go into decline as opposed to a sudden, plant-wide die-off.
Anthracnose is a term used to loosely describe a group of related fungal diseases that typically cause dark lesions on leaves. In severe cases it may also cause sunken lesions and cankers on twigs and stems.
The best remedy for lemon tree problems like chlorosis is to improve the pH of the soil. You can acidify overly-alkaline soils by applying a solution of ¼ -½ cup of white vinegar in 2 gallons of water, planting citrus fruits cut in half face-down in the soil or using a commercial soil acidifier.
Another way to eliminate fungi from trees includes spraying affected trees with a light bleach and water solution. Most Household bleach is around 5-6% active ingredient and diluting that down to a 10:1 or 5:1 ratio probably wouldn`t hurt your trees as long as they have gone dormant.
Burn or bake gall-infected off-cuts: Treat gall-affected branches before disposal by placing them in a well-sealed plastic bag in the sun to bake for a month or incinerate them. Wasps can still emerge from galls in pruning off-cuts.

How do you use roundup to kill a tree stump? – Roundup "" Weed & Grass Killer
Hello, I am a grower and licensed pesticides applicator (40 yrs exp).
Roundup lost the trade mark years ago,”glyphosphate” which is now marketed (cheaper) under many other names,
Will kill a live tree if sprayed on the leaves! Also will damage young trees if you just get over spray on the trunk while spraying weeds.
Also, kills grass as well as broadleaved plants.
To kill a tree you would need to spray the leaves, then wait at least a month before cutting the tree down. I have successfully killed a few stumps by spraying the live suckers.
Be especially careful of spray drift as the finer the droplets are the more effective the chemical is. Read the label!

Check out the power to the timer
Digital Multimeter Mastech, verses Fluke, Unfortunately I damaged my good old Fluke 87-3 when I measured a 3 phase motor supply while still in ohms mode, one of those o-**** moments when you hear the meter freak out and know without even looking at it. Still works but brain damaged and I don’t trust it anymore. Anyway looking at various meters on the market and came across this mastech meter on ebay item 200461965472, I know its not a Fluke, but I like the features it boasts and of course the lower cost than Fluke, has anyone used this brand? Any good? One thing I like is speed are these fast or is there a delay like most meters other than Fluke. I would like to hear from someone who has actually used one of these or makes. Also looking into PC based meter/O-Scope/Function generator where the PC or laptop is the display/control with a interface box with in/outs. Has anyone had experience with these and can recommend makes, models.
I have had experience with both systems you are inquiring about. personally, I think you should get a Fluke, NOTHING even comes close, as I am sure you are aware, any extra cost is soon made up for by features and reliability. I haven’t had very good results using Virtual Instruments, they are OK, but.. very cumbersome, in use etc, you just cannot beat a “scope. Now I really recommend the Fluke Scope meter, they are just awesome, in every way.. I have had VERY good results and a cheap repair, when I sent a damaged meter back to Fluke, they reconditioned it and calibrated etc, and the cost was as i remember very reasonable, for what was done, so perhaps you would like to entertain that thought. You can always ask for a “Quote” before allowing repair to proceed, that way you have little to loose. There are many meters and instruments out there, and as you know, a man is only as accurate as his equipment, and I always recommend Fluke, as they are simply the best. Possibly a bit Pricey, they are always worth it. So go with your first instincts, which were indeed right on the money, Fluke all the way. As I said have a look at the Fluke Scope meter, and possibly treat yourself to a wonderful piece of equipment you’ll fast wonder how you ever did without it before.
Danger of roundup applications around tree and bush plantings
Hi , I would be very carefull around good plants. Roundup will kill almost any plant, including aquatic plants, so you want to be sure to avoid spray drift onto other plants or into water.
What can cause no new growth on my 2 year old potted ******* and the leaves though looking healthy are falling. ?HELP??
It may need more room for its roots / a bigger pot with fresh potting soil for additional nutrients.
In 2006 I purchased an automatic transmission Craftsman lawn tractor, model YS 4500 / 917.276641. A couple of months ago, it started not going forward or back well. It would eventually work, when I did everything just right, but slowly. After another use or two, it quit moving at all. (It starts with no problem, and the blades work fine.) I looked at it until I noticed that the ground drive belt seemed crazy loose and while the pulleys were turning, it wasn’t. Thinking that didn’t seem right, I went to my local Sears and the salesman agreed it sounded like a loose belt, so he ordered me a Hydro Ground Drive Belt, part no. 140218. When it arrived, I noticed it’s white instead of black like my old one, and seems 6+” shorter. I attempted to install it per the instructions in my manual. I get it around the mandrel and idler pulleys with no problem, but there’s no way I’m getting it around the clutch pulley. In my further research, I’m wondering if it would more likely be the motion belt, anyway, if it’s a belt issue at all. I would appreciate any help/insight. Thank you!
