January
It is the coldest month of Jinhua. The temperature can be dropped from -9¡æ to -6¡æ. The most important work in this month is to take the measure of keeping warmer to prevent the fingered citron from cold and to protect the leaves. Close the doors and windows of the large canopy which set up by wood and bamboo and covered by sheet film. Add to apply fertilizer to improve the performance of heat preservation for the soil of bonsais, then promote the bud continue to split up. Control water strictly and prevent the soil of bonsais from waterlogging. Keep the pit and the greenhouse certain humidity.

February
The temperature rises again gradually. The fingered citron tree grows step by step from dormancy. The circulation of sap begins slowly. The bud is splitting up.  Go on preventing frostbite and keeping warm because the temperature is still cold. Open intakes of the large canopy at 9:00 a.m. -15:00 p.m. if the air temperature is higher. Water properly if the soil is very dry.
Impose and can transfer to basin, divide into basin, field planting , carry on  cut preparation of answering,  etc. the middle ten days.

March
The temperature rises again slowly. It is lower in the first ten days while it is higher in the last ten days. The flower bud differentiation enters the middle period and the morphological differentiation finished. Begin to bud in the last ten days. The root absorbs a large amount of nourishment. Fertilize the compound fertilizer, such as nitrogen, phosphorus, potassium, etc. to let the branches and leaves grow better and bear fruits better in spring. Prune the young tree into three boughs, which likes the trifurcate shape. Change basins, separate bonsais by each grade and plant in the same range in middle ten days. Do some preparative work well for Ǥ²å, stem cutting and graft.

April
Temperature rises warmly. Put out the golden fingered citron on the fine days in the first ten days. Manage the tips when the golden fingered citron grows new tips too much. The absorbability of the root is strengthened, the new root will outgrow in the last ten days. Because of long assimilation, the strong trees accumulated nutrition material continually, it bloomed and bore fruits, and some young fruits grew already big like the thumb. The young fruits will fall down if there is too much rainwater. Take the measures to protect the flowers and improve the output.

May
It is obvious that the flowers and fruits of the golden fingered citron fall down.  Spray borax and so on after diluted to protect fruits. At the same time, do flower thinning and fruit thinning. The growth of the root enters the prosperous period so you should do waterproof and waterlogging well. Use graft and layering to propagate the golden fingered citron.

June
Temperature is high. The young fruits are in the developing period. Some summer flowers begin to bear fruits. Continue to do flower thinning and fruit thinning, remove male flowers and remain female flowers, remove bad fruits and remain strong fruits. Fertilize by times and prevent plant diseases and insect pests in time.

July
Temperature is extremely high. It is much rainwater in the first ten days. Let young trees produce new tips better continually and form tree crown. Prevent mildewing the root. If the condition is suitable, the golden fingered citron gestates buds from the last ten days of June to July. Control water and fertilizer  in this period. Pay attention to manage worms.

August
Temperature is high. There are many hermaphrodite flowers. The rate of fruition is high so long as the condition is suitable. Fertilize phosphorus and potassium well to promote the fruits swell and grow. Use graft and layering to propagate the golden fingered citron.

September
Temperature is on the high side. The autumn tips grow rapidly, more and regular. Fertilize phosphoric fertilizer and potassic fertilizer to let branches and flowers grow better. Continue to prevent plant diseases and insect pests. The fruit continues to grow. The spring fruits turn to golden yellow and can be picked.

October
The root grows in the third time in the first ten days and slows down step by step in the last ten days, and the fruits ripe gradually. Add to fertilizer in time to renew the growth tendency because the tips use up nourishment more and the nutrition in tree lose more too for long-time with fruit. The bud is grown in the fourth time on tree in this month. Many of them can not bear fruits for lower temperature, you should pick them off.

November
The fruits have been gathered. The temperature drops to about 13¡æ. The root and leaf stop growing. The bud begins to morphological differentiation. Go on fertilizing, use phosphoric fertilizer and potassic fertilizer more, and do not use nitrogenous fertilizer. Put the fingered citron into the greenhouse or the soil canopy and do well the preparation of living through the winter. Pick off the leaves in the late autumn.

December
The gold fingered citron stops growing, the bud differentiates. The activity of the root is lowered, the lamina accumulate the nourishment. Regard resisting cold and preserving heat as the centre work. Increase natural illumination. The soil of the basin should be properly dry.
