Crabapple Tree problems

11 posts in this topic

Planted a crabapple tree last year and it recently lost all leaves on mmost of the tree. The chutes at the base of the tree are still growing well. Should I trim the chutes off or leave it alone until next season.?

That's kind of what I was thinking, but not sure of what to do.

Those suckers will turn a nice tree into bush if you dont keep the suckers cut back.

Did the leaves turn yellow or anything? If the leaves were yellow with black spots, its most likely a condition called apple scab. Its a fungal disorder that effects the leaves back in the early spring when they are just popping out.

Its very common and very easy to prevent. Unfortunately, you have to prevent it in the spring with fungicide treatments when the leaves are just popping out. If the tree is small enough you can do it by yourself. Check out a nursery or garden store for info.

No, they budded out and got the leaves, then they all started dropping off, then the chutes started at the base up to bottom branches and have been growing fairly rapidly.

With the wet spring we had, I also have this on my crabapple, Power stroke is right, it is a fungus. I took a pic to Noble landscape and she showed me all the trees like mine and low and behold the samething. Next year you hve to spray them and you will be ok.

Thats my problem with Flowering Crabapples. Everyone loves the spring flower, but most varieties have so many disease, fungus and other issues. Last year a bunch of them in my neighborhood defoliated in July.

If your going to buy a new crabapple, make sure you buy a variety this is disease and pest resistant.

Crabapples and other trees get a very similar fungal disorder. The leaves come out fine in the spring stay green and healthy until mid-late summer then all of a sudden they start getting spots, turn yellow and drop off. It looks like October in the yard, but its only August on the calender.

This happens with apples, oaks, ash and a few others. The oaks and ash get anthracnose (not anthrax) but its very similar in its infection.

You won't know if your tree is infected until its too late to treat. To prevent it you need to spray in the spring. Timing is somewhat critical, but easy to do.

Apple Scab treatments were out largest and most most common treatment at the company I worked for.

So the tree should be ok next dpring then, I will just need to spray it to take care of the fungus then. I appreciate the advice.

    • Here's number 3 for the year! Not a bad find for a couple hours after work.  It was so fresh it still had wet blood on the base.
    • East wind is the worst...!! Bad juju. Always means a storm. Gonna have an East one tomorrow......and my barometer is already headin' down, in time for the 6-8" of big snow tomorrow. Watch it plummet before a big summer storm, or rise into the 30's on those warming, clear days. I've always watched the winds and barometer since I was a kid (got into the weather thing in "science class") , you can do better yourself than the forecasters do. It's easy and fun, IMO. Some fun facts:   http://minnesota.cbslocal.com/2010/10/27/lowest-barometer-reading-ever-in-minnesota/
    • I guess I never associated a north wind wind lower pressure. Or a south wind with higher pressure.  Learn something new everyday
    • I watch when it drops below 29.5 Hg on down (29.0 Hg or mb; millibars) or when it swings up past 30.0 mb. That's my reference for "highs" or "lows" on my Barometer. Remember to adjust yours to your local Wx reading, they have a slot shaft in the back of the meter for that. I  love my old dial Aneroid barometer.  They last forever, too.  Mines kicking about 35 years... (That's not mine, pic is for low and high reference...)    
    • Thanks Rebel, very good answer.  I've been keeping track of the pressure for a week, now. 
    • Hey Rebel, what do you consider low and high pressure?  Perhaps a stupid question, but I just got a weather station so now I can start tracking barometric pressure. Right now the numbers don't mean much to me, been around 28-29% in the south metro the past few day and I don't know if that's low, high or middle.
    • Low pressure signals a front moving in, (Bad weather, wind may be  from the east or north) which usually puts them "on the feed", can have some hot and fast action. Likewise, a swing in the other direction, a high pressure system , (wind from the west or south) which signals clear skies and sunny weather, may do the same. The key to me, anyway, seems to be hitting it just as either front moves in. An extended low or long high may result in poor fishing. Remember the old adage, which also has to so with the pressure: "Wind from the east; fish bite the least...wind from the north , the fisherman goes not forth, wind from the south, blows the bait in the fish's mouth; wind from the west, is when the fishing is best". 
    • Those trumpers sure know how to keep things classy.
    • Is it true, the lower the pressure, the bite gets hot? Or the higher the barometric pressure the fish slow down on biting?
