I hold a lilac tree that have wide purple flowers, but closing year 1/3 of the tree also blooms white flowers.? Someone told me to trim the white lilac flowers after it...
Someone told me to trim the white lilac flowers after it bloomed and then subsequent year the whole lilac tree will bloom adjectives deep purple flowers. This year, the tree seem to be blooming even more white flowers! How do I get the together tree to bloom all purple flowers, as it should? It looks funny near some deep purple and some white. In long-gone years, it was adjectives deep purple. I own mulched it and put lyme to keep smaller amount acidic. Help?!
If the white flowers repulse you, cut put a bet on those branches - not just the flowers (or fleck them and trim later). It would be best to cut them late summer or spatter so that you remove next year's white flower buds that form this season. It is possible you own 2 different plants growing together or it was graft to have 2 colors on one plant. I don't guess acidity affects lilac color (as it does hydrangea).
Is it possible that your tree was graft? I have see other trees that were graft have some of the graft traits & some origional. If so and the origional be white, you would have to trim everything past its sell-by date below the graft.
I don't think two colors of flowers look funny. If it is viney, I would entwine the t colors of branches together so I had rather of both colors all over. Right in a minute I am dealing with a hybrid rose bush that have yellow, pink, and ashen with pink tips on the blooms of like bush, in varying digrees of color saturation. Strange, but I love it.
Answers: It is because it have heterogeneous genes.
Sometimes it will bloom white, and sometime purple, because of the parents.
