Reading from Peter Chan's "Bonsai Masterclass" It is recommended to use a high nitrogen fertilizer from spring till late summer. Then switch to tomato fertilizer or rose fertilizer which is low in nitrogen but high in potassium and magnesium in the early autumn. This is especially benefical to flowering and fruiting trees.

Fertilizing should then cease with the onset of winter as trees lose their leaves. The exception to this are pines and junipers that can be fed all year round apparently.
