I have a lilac and peony who have been established for around 8-10 years now. Trees have now grown over them, so the only sun they receive is during the first part of spring before the trees get leaves. Since they're full sun plants, won't they die? They're actually both blooming at the moment, and I would like to know if I need to plant more in order to have blooms next year. They're family favorites for sure!

You are a crazed hoosier ! Like me.
'Thank You ! Thank You, Very Much !'
Not thinking about trees growing much in ten years ! Hoop-tee-toots-ey. Ohh well, happens to the best of us ! 🙊😞😀😀😀

Opps 🙊!!! I get carried away sometimes.

Without seeing your setup, I say you have two choices. Raise, your trees. That's, pruning some of the bottom limbs off, to make them taller off the ground, letting some sunshine in under them.
That, could be done now.

Or ! Come transplant time, in fall or late winter, transplanting your lilacs and ponies to sunnier location.

They will probably not die, but rather not thrive and a reduction in bloom production. Like Phillip said transplant would be a good idea.

Yea, if you limb up your trees so they can get a little more light I wouldn't necessarily transplant them if they look good and you're satisfied with a little less bloom.
I have many roses, junipers and other sunlovers that grow in the high shade and partial shade of oak trees. They perform quite well.

Thank you all for the replies! I think I'm going to cut some bottom tree limbs, as suggested. I'm not sure how much more sun will be added from that, but I'm sure you'll all be hearing more from me if there's no change! If a good amount of sun gets added back into the equation, I may plant a knockout rose and butterfly bush near the lilac!

Cool. Keep us posted.
BTW, here's a pic of one my Rosa 'The Fairy's. It grows in the high shade of Willow and Pin Oaks and receives very little sun. It's just coming into bloom now. Not as much as if it were in full sun but respectable enough. Placed it there as a cutting in 2012, if I remember correctly.

Wow, that's amazing! Congrats! I've always been a little hesitant to plant roses because of the supposed problems relating to them. I decided on the pink double knockout rose because I heard it was beautiful, easy, and had extended bloom times.

I would would go for the Pink Knockout. If you do well with it it might give you the confidence to try other roses.

Don't be afraid of growing Roses.
The are perty carefree, and there TUFF. You can't hardly kill them. There drought tolerant, up the wasszoozoo !
I've almost never had a bug problem with mine, and one spraying took care of them, and Bugs, weren't very often.
They do like lots of sun though.

Other than pruning the lower branches of the shading trees, depending on the trees, it might be a better or alternative idea to thin out branches at all heights and even lower the height of the whole tree. Just because a tree can grow to 70feet, for example, it doens't mean you have to let it get that big.
