Last spring I planted a two gallon weigela and it seemed to be doing well but this spring I didn't get any new growth from the old branches. The new growth came up from the bottom, kinda like a rose that has gone wild. Is this normal? It hasn't bloomed. Will it come out of it or is it a lost cause?
Your plant may have been killed off by the winter.
You can trim off of all the dead material and allow the shrub to grow. It may take time for it to become a nice size again.
You also could try to see if the garden center would replace the shrubs. Most garden centers offer a 1 year replacement on shrubs.
Here are a few links for you.

We recently had extensive landscaping done and we included the Red Prince Weigela. It has been very hot here in eastern PA. so we have been watering every day. The plants do get full sun. We were wondering if we might be over watering them. They look like they are turning brown at the bases. Should we water more often, or less often? Help, I don't want to lose them.
It is possible that there are air pockets in the soil that are affecting the roots. I would step firmly on the root balls to help collapse any air pockets. Flood the area with water to help fill them in. Up its watering as well. It may also have a fungus disease, so I would treat the plant with a fungicide.
Our weigela bush is about 5 years old. It blooms in spring but this year after blooming all the leaves are turning brown and it looks like it is dying. The branch itself is still green when I clip it. It has been very hot and we have had lots of rain. Should I cut it back and how much should I cut it?
This could be due to the heat stress and rain. Pruning off the dead growth may help. This article will help you: https://www.gardeningknowhow.com/ornamental/shrubs/weigela/pruning-weigela.htm
How can I get rid of a weed maple tree that is growing in amongst a weigela bush. I have a weigela bush that has had a maple tree growing from the base of the bush for a few years now. I have repeatedly cut it back but it still keeps growing. Can I use weed killer on the cut without endangering the bush?
You can cut the weed tree down as far as you can and paint the cut end with a full strength herbicide.
This should kill the tree.
Remember the herbicide will kill everything it comes in contact with so be cautious.
Plant is in its first year, 6 months old. It had hot summer but tried to keep watered. They look like they are dying, leaves curling and stems very woody looking. They did have a few flowers earlier in summer but are gone now. Should I prune all the way back to ground and hope for the best next year, or if not, how do I get them to spruce-up after the rains came along with the cooler weather?

I recently bought numerous plants on sale and I'm not sure if I should plant now or not. Today is September 25 and I live in zone 8a (SC). Here is the list: Proven Winner Wine and Rose Lantanas Barbara Karst Bouginvillea Goldmound Spirea purple verbena dwarf crape myrtles Early Start velvet phlox dragon improved asters blanket flower Bougainvillea Trellis Japanese Pieris Sun Parasol climbing Mandevilla snapdragons Dianthus Clavelina Dipladenis Red mums I've been trying to read about each one, but I'm just confusing myself with so many. Will these plants survive the winter if I plant these in the ground now? If not, will they survive the winter in the pots or how should I protect them for winter.
A majority of the plants you listed will do just fine in the ground and winter over.
I have listed a few links for you to get you started.

Please can you identify this plant for us. We believe it is a spring plant and would like to know if we can promote continued flowering for a longer period please? Kind regards ... Kim & Phil Short, West SUSSEX.
I believe this is a wigilia (not sure that is the correct spelling)
