After first flowers appear, apply standard liquid fertilizer every 2 weeks in Spring and Summer.
Re-pot annually in Spring as new growth starts.
Plant 3-4 inch cuttings of early Spring growth in a 3 inch pots of moistened cutting compost or equal parts peat moss and perlite. Place cuttings in a plastic bag or heated propagator. Let them in bright filtered light. After 2 months, move them in standard mixture.
Allamanda is an easily grown plant, that prefers a warm greenhouse or conservatory. If humidity is high in the home, it will grow well.
After flowering, it should be cut back to one joint of the old wood in mid Winter.

Watering is necessary when transplanting, but be careful not to over water.
