For several years of repeated flowering, plant your bulbs in fertile, well drained, but not too dry soil. Especially under trees I recommend you monitor the humidity of the soil, as trees absorb a lot of water.
If you have very wet ground, like for example clay ground, first improve the water household. This can be achieved with compost, good drainage and by working in grained sand. Sand allows rain to sink more rapidly.
Sun or shade?
Most flowerbulbs (such as tulips and daffodils) thrive well in sun or shade. However, after several full days in the full sun, some of the intense colours tend to loose their radiance. In regular semi sun/shade situations, most varieties will outline their colours more sharply during the flowering season.
Perennial flowering of flower bulbs?
Should you want to keep the bulbs for the next year, then it pays off to get sufficient quantities. Make sure to remove seed pods after flowering and let the plants continue to grow and provide the bulbs with growth potential until the foliage dies naturally. During this growing, the plants need, as it happens, sufficiently form food. Dig up the bulbs and keep in dry and ventilated place until next planting season.
Rotation of crops
Also, it is better not to plant two consecutive years in the same spot. Rotation of crops is best for a healthy soil, therefore plant daffodils where tulips were and vice versa.
And finally, it helps if you regularly use a good (organic/biological) compost on your garden. With that you improve the health and capacitance of your ground.
