| I'm sorry, I'm not sure what the type of tree is! I just happened to go out there today for some weeding (There is a small garden at the base) and I finally noticed the struggle this poor tree appears to be going through.
Can anyone help me out by identifying any of the following:
It has been humid lately, ranging from 80-90 degrees in temperature. |

| I'm thinking crab too. Cedar-apple rust, apple scab, or some variant of anthracnose. If it's CER, there is an alternate host plant somewhere in the area-a juniper. It will be very hard to control this disease without a heavy fungicide schedule so long as both host plants are near to each other. If it's scab, the only realistic preventative measure is to plant only those varieties having a good deal of natural resistance to this pathogen. If it is some type of anthracnose-not a single disease really but more of a symptom-thorough raking up and disposal of the fallen leaves in a hot compost pile, or better yet in my view, the use of a mulching mower to chop the leaf pieces into the turf matrix where they'll decompose-are possible solutions. +oM |

| Yes, that is CAR. Millions of apple trees get it every year, and they survive it every year. It's really more of a cosmetic problem than a serious threat unless it is extremely severe and defoliates the tree repeatedly. You could spray early in the season, it's really too late now once the lesions appear. |

| Some crabapples are more resistant that others. The vector in your area is likely the trees called cedar, which are actually junipers. Since cutting all the junipers in Scarborough is out of the question, see how the tree does. Some years are worse than others, and if it does continually kill the small branches, you might consider another, more resistant selection. |

| Looks like some small, six-legged critter has been eating on the leaves too. But again, by this time of summer, and especially by this time of THIS summer, that is to be expected. It's a hungry world out there! +oM |
