    The signs of pre-mature leaf drop that you describe could be the result of water deficit (drought stress).
    Poplars have a high water demand and if you are having a heat wave or drought, you may need to deep irrigate heavily to save it.
    There are possibilities for pest and disease issues, but the drought stress is most likely.

    Zone 7 temperature-wise it should be okay, as long as you can give it good growing conditions and plenty of water.
    Hardy in USDA Hardiness Zones 3-9.

    But I don't have personal experience with balsam poplar in Oklahoma, so check with a local nursery, landscape professional or arborist, or university ag extension service.

    This is definitely infected with a fungal infection. This could be caused by the aphids, or can be why the aphids are there now. You can try adding wettable sulfur and dolomitic lime to the soil around the tree. This can help kill off the infection while keeping the soil pH stable.

    I would definitely hold off on any watering, unless it remains dry and the soil is completely dry down to about 2 inches. Overwatering will cause an infection very quickly.

    As for the insects... This collection of articles will give you ways to control these along with other useful tips: https://www.gardeningknowhow.com/special/organic

    If the ground is not frozen and there is still time for the plants to get established, I would go ahead and plant them. The bulb foliage should regrow if a frost nips it. And trees are best planted in fall. But if you are in the throws of winter, you can hold the perennials and trees till spring.

    This article explains how to care for the roots until the time is right for planting:

    Figure 50 to 150 years, depending on the sub-species, cultivar, and the growing conditions.
