Answer: It may be that because the roots are so restricted they aren't getting the moisture they require. Even though you are diligent in your watering practices, plants in containers use more water than the same plants in the ground, and, sometimes air pockets form within the root ball that elude detection. So even though the soil seems moist, there may be some dry areas within the rootmass. You can try immersing the nursery pots in a larger container of water to thoroughly wet the soil and drive out any air pockets. When bubble stop rising to the top, the soil is saturated and you can remove the pot from the watering container. I'd rehydrate the soil and then plant the pines as soon as possible. If the candles continue to wilt, snap them off. Once the roots are established the pines will resume growing and may even over-take the established pines in your garden. Best wishes with your pines!
