What's the deal with my lilacs?
Um, what is the deal with my lilacs this year? Most have little to no flowers this year, same with buds.
They're a few years old, have flowered previously. From different sources, some were from seed, some were from cuttings.
Full sun, soil not too rich, pH neutral, I think. No drought but no torrents of rain either. I don't feed them and I haven't pruned them yet. Some are putting out suckers like there's no tomorrow but are stingy or non-existent on flowers this year.
Could it be because of the short winter this year? It got cold late and then got warm sooner than usual with some really warm days thrown in when it should have been freezing.
