    If you're simply deadheading the plant, or removing the spent blooms, all you need to do is snip off the bloom itself. For all other pruning, here is more information: https://www.gardeningknowhow.com/ornamental/shrubs/lilac/pruning-lilac-bushes-when-to-trim-lilac-bushes.htm

    If your lilacs are lush and green, but have no buds or blossoms, it might be a sign that they are getting too much nitrogen. Use a general purpose fertilizer high in phosphorus in the early spring. Lilacs like to have lots of sun, so if they’re in a shady area, they may not bloom well. Fertilize your lilacs once with the same type of formula again after pruning. This article will also help: https://www.gardeningknowhow.com/ornamental/shrubs/lilac/lilac-bush-not-blooming.htm

    It could be a fungus or it may have been thrips. Treat the tree with both a pesticide or a fungicide. I like neem oil myself as it is both a pesticide and a fungicide and is organic.

    Frequent fertilizing isn't necessary; however, you can use a general-purpose fertilizer (low in nitrogen) in the spring to help give lilac a little boost. Also, add some compost and bone meal in and around the soil.
