Although easy to grow these tips will hopefully prevent problems.

They need acid soil (PH 6 or lower) preferably kept moist but not wet (well drained and humus rich) I keep my pot grown plants on the dry side in winter.

My present mix for pots is 10lts crushed Bark (14%)    37.5lts bagged Ericaceous compost (51%) and 25lts lime free bagged soil (35%),  some people also like to add charcoal, I then add Osmocote slow release fertilizer.

Lapageria like high humidity, avoid dry situations. If destined for outside then I would advise growing on in a 7.5 or 10lt pot for a further year or two to have a good sized plant to plant out, choose a plastic pot that can be cut away to avoid root disturbance.

They have large root systems, so if destined for a pot they need a large one (but you build up to that over time.) bear in mind the need for repotting when choosing pots (some are too big or the wrong shape to allow you to re-pot, I prefer plastic because I can cut them away when re-potting but often place these inside a nice pottery one)

Be careful not to disturb the root system too much while repotting (cut the container away), avoid repotting young plants, better to leave in the original container until roots are hanging out of the bottom. They resent root disturbance and often sulk for periods after.  

They dislike heat and strong sun light especially at the roots and lower stems, so place in cool shaded positions. However plants will grow in hot places if the roots are kept cool. 

The young growth is very sensitive to damage, avoid manhandling it or allowing mechanical damage from wind. Frost can also be a problem in spring (Lapageria are very good under cold greenhouse conditions) but the adult growth IS frost hardy and they can be grown outdoors but require a wind sheltered position and an acid soil.

They are not prone to any pests or diseases but watch for snails in spring, and if aphids become a concern I find a spray of plain water to knock them off is best. Remember that the little snails that turn the leaves to lace do not go down the the ground but live up in the plant so slug bait at ground level is ineffective, I used to spray with a liquid slug killer, but that has been withdrawn!

Flowers appear on newish growth that hangs from the top, (July to March under glass and occasionally at other times) so allow plant to climb up and then cascade down.  

Once going they are easy and trouble free and flower for 6 months or more! You may get in contact at any time if there is anything else you wish to know.
