    It likes full sun, but try this to get them going:

    Plant them in the container and water thoroughly. Then set it in a shady area for 1-2 days (to adjust to being planted). After that, move the plant to a sunny location. Water them two times a day for the first week and once a day after that. Also, make sure that it has good drainage in the pot.

    You can try trimming them back some. It does sound like the plant may be getting a bit too much water, and with the intense sunlight, it may simply be suffering from a bit of shock. Make sure to only water when the soil is dry to the touch on top but not dry all the way through and try moving it to a shadier location for now and gradually increase the light.

    It is not a fussy plant with watering, but if the root balls of the plants were dry when you planted them, this may be the cause of their dying. If the root balls are very dry, they may actually repel water after you plant them. Make sure the root balls are well watered before you plant them and keep them well watered for about a week.

    You can try watering them from above, but, depending on how congealed the sap is, I am not certain how well this will work.

    Lobelia is a herbaceous plant and most methods to remove sap are somewhat caustic so would hurt this plant. It may be best to just remember not to plant annuals in that spot for next year.

    Yes, you can trim them. It does sound like the plant may be getting a bit too much or too little water. Make sure to only water when the soil is dry to the touch on top but not dry all the way through.

    Lobelias can benefit from a trimming to help them grow better. Cut the plant back by about a half to encourage new growth.

    They may also be in just a slightly too shady spot. If you can get them to a brighter spot, this may help.

    You may also want to water more often. In a container in summer, plants need to be watered at least once a day, twice a day if temps are over 85F.
