Welcome to Berner
Willc has very good advice , a good balanced , time release food , " osmocote" or one of the vigro products will do
ignore most of the words on the pack ,just look for the numbers
there are always 3 , 20-20-20 , 10-5- 8 , 15-5-20 ,I know that this can be a bit confusing, but just think of what you are trying to produce in the plant . IE leaves , flowers , roots
the numbers are for nitrogen(leaves) - potasium(flowers) - phosphoric acid(roots)
so unless you are trying for only one thing (like a palm tree )a balanced food will cover all of your plants
this group is sooo wonderful , there are people at all stages of plant knowledge , and it is such a blessing to be able to ask questions .
good luck on your new house
