How do I get more blooms off of my lilac bush?

How old is the Lilac? Where do you have it planted?Has the bush been fertilized?Have you pruned the bush at any time?

I just bought the house last yar, the bush is about 5' tall a couple feet wide, I have never trimmed it, don't know if previous owners did

if you only have one bush, its best to have at least two. for some reason (pollination i would guess) that helps.

but trimming helps often if you take the suckers off the bottom of the bush.

i'd say, go to your local garden center and ask a pro. there are so many reasons why it may not be giving you more blooms. and they should know!

Some years ours has more blooms on it than other years....we live in the midwest and found it depends on how cold it is in the winter. We had a mild winter last year and had so many blooms this spring. We do trim the bushes every two or three years and we get less blooms then also, but still have blooms on the old untrimmed branches.

We do have two bushes about 6 feet apart..

I live in Tacoma WA. When I bought my house it came with an old lilac tree. Mine's about 12 ft tall now. I tried to keep it at a height where I could reach the blooms, but after spending 2 yrs with my dad in Texas it got away from me. When you prune, every cut you make should send out two new shoots. My tree blooms on new wood so this multiplies the blooms. It was broken off in a wind storm a few years ago, so suckers are prolific now so I dig or cut them out every spring. I even started a new tree from one of the suckers. That was about 9 years ago and I just kept cutting it back every year. It was 7 yrs before it bloomed but now, in it's 9th year has set over 100 blooms. It's been a learning process for me, but it was worth it. I've never fertilized it, and now that I think of it I wonder if I should. The photo is the one I started from the sucker. My goal now is to prune to make it fuller and remain reachable.

there is a saying that everybyear, after bloom time, you should remove one third of the canes by cutting them to the ground. Look for the oldest canes, keeping in mind the overall shape of the bush.

you need to prune and feed your plants for them to continue to produce!!
