Amazing Race, Why are you repotting your Norfolk pine? If your Norfolk pine only needs watering once a week, it doesn't sound like it needs to be repotted. Repotting plants
that don't need it often leads to root rot because the additional soil in a larger pot retains too much moisture.
Norfolk pines require very bright indirect light. When they receive enough light the soil should dry out about 1/4 between waterings if they are potted in a properly sized pot such as the original grow pot. plants
that recieve lower light need less water. If that is the case for your pine, try letting the soil dry out 1/3 to 1/2 between
Also, if you only received the plant
in December, it isn't a good idea to repot now anyway. plants
need several months - at least 6 - to acclimate to their new environment and repotting during this time unnecessarily stresses them.
I second what's been said about removing dead brances, but caution you to not remove the top of the tree
as Norfolk pines only have a single growing
Fertilizer should only be applied to healthy, actively growing plants
and even then sparingly. My suggestion is to give it optimal bright indirect light (a couple hours sunlight every day is OK) and give it a bit more time before making any major changes in its care.
