What kinds of butterflies are most attracted to lilac trees?
There are far too many types of butterflies to name and many of them are attracted to lilacs. However, the tiger swallowtail dies include lilac shrubs as one of its favorites.
I am building a raised flower bed around and older lilac bush and was told that adding more soil will kill the lilac bush. Will this harm or kill my lilac bush?
When we first moved into our home in town, two lilac bushes had portions of their root systems poking up through the ground surface. I cover the areas with 6 to 8 inches of new amended soils and they did just fine. So adding more soils for your raised flower beds should not be a problem.
I've read here about trimming a lilac bush, but here's my question. . . I planted a 4-inch lilac bush into a pot for my patio this spring. It has grown beautifully and some of the stems are a foot long and blooming. The leaves on the stems are to the dirt line, and I assume this is because it is a bush and not a tree. To ensure a thicker stem and continued full growth with blooms, how do I properly trim this? I live in Savannah, GA.
You can remove the lower branches to form a more tree-like shape.
I hear that if you do not remove the seed pods the bush will not bloom next year. Is this so?
While it will still bloom, leaving them could inhibit flowering (slow it down), so most people prune the shrub just after blooming. This article will help with that: https://www.gardeningknowhow.com/ornamental/shrubs/lilac/pruning-lilac-bushes-when-to-trim-lilac-bushes.htm

We have 4 lilac trees along our back fence. Two years ago, one of them became brittle and dead looking and produced no leaves. It is now spreading to the other three. Yesterday I was able to break it off at the ground level or simply pull it up at the ground level. What is happening?
The trees are likely infested with some type of insect or have a fungus. You can remove any dying, brittle growth and treat the lilacs with neem oil. It is effective in treating many types of insect pests and is a fungucide as well. Here is more info: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
