Seed crops

In a forest setting, heavy seed crops are a blessing. In a residential setting, they are a curse. The elms, this year, have produced a bumper crop of seed and gardeners are likely to rue the fact later this summer when they all start to sprout. Right now the seeds are beginning to mature and brown giving the elms a yellow appearance that can be alarming. Citizens who have heard of Dutch elm disease have been frantically calling to make sure their trees are ok. Most are fine. However, signs of Dutch elm disease are beginning to show up, slightly ahead of schedule, so telling the two conditions apart may be difficult to do until the seeds begin to fall. Check for wilting leaves and bark streaks on affected elms if DED is suspected.
