    I planted lilacs three seasons ago, but it has never flowered. The tree has gotten pretty large. Someone told me to use lime, so I did. I dug out a little dirt next to the tree and put the lime directly in, then watered. I don't remember if I did that last fall or in the spring. I didn't get flowers this year either.

    Lilac can take sometimes a few yrs to bloom. Its the middle # in fertilizer (Phophorus) that relates to blooming. It should be higher than the first. Every yr, I take a bucket of hard wood ash from the stove and put it around the drip line of the plant. I get great blooms on 40 yr old plants.

    Here's a good link. If you scroll to the bottom, there is a list of reasons why they don't bloom.

    We get that question all the time at our master gardener clinics. Most of the ones that don't bloom don't get enough sun or heat.
