Culture methods of summer plum

Light and temperature

Summer plum can withstand short-term high temperature of 40 ℃ and cold temperature of-15 ℃. Summer plum likes to be warm and humid, and the environment with weak sun is more suitable for its growth. If summer plum is exposed to full light for a long time, it will cause its leaves to turn yellow and grow poorly. Therefore, Xia Lamei should avoid direct sunlight and stay in the sun for a long time. You only need to give it a proper light temperature every day.

Second, watering

Chimonanthus is resistant to drought and afraid of waterlogging, so the soil needs to be kept in a semi-humid state, but it can not be short of water in summer and should be drained in time in the rainy season so as not to affect the formation of flower buds. In the flowering period of summer plum, the amount of water must be reasonable, too little watering will lead to irregular blooming; too much watering can easily lead to falling flowers and buds.

3. Soil

Summer plum is suitable to grow in sandy soil with loose fertility and good drainage. The basin soil can be prepared with sand slope and coniferous humus at the proportion of 1:1.

IV. Fertilization

Summer plum likes fertilizer, timely fertilization can promote flower bud differentiation and blossom more. In spring, leaf fertilizer is applied twice, and summer plum is fertilized every half a month or so from the end of June to the eve of ambush to promote the formation of flower buds. Fertilization can be applied again in autumn to enrich the flower buds. Apply topdressing two or three times after flowering to before defoliation. Apply thin horseshoe water again before the beginning of winter to provide nutrients for flowering to help it through the winter.

After understanding the culture method of summer plum, let's take a look at what we need to pay attention to.

Culture methods and matters needing attention of summer plum

Culture methods of summer plum: temperature and light

Summer plum can survive winter and summer normally in Jiangnan and other places, and can withstand short-term high temperature of 40 ℃ and severe cold of-15 ℃. Like warm and humid, the sun is not strong growth environment, in full light leaves turn yellow, poor growth, so to avoid direct sunlight, long-term exposure to the sun, the right amount of light can be.

Watering

Chimonanthus is resistant to drought and waterlogging, and the soil can be kept semi-moist. Drainage in time during the rainy season. But in summer, there can be no shortage of water, so as not to form dry and whitish patches on the leaves and affect the formation of flower buds. In the flowering period of summer plum, the amount of water must be reasonable. If there is too little water, the flowers will bloom irregularly; too much watering will easily lead to falling flowers and buds.

Soil

It is suitable to grow in fertile and loose sandy soil with good drainage. The basin soil can be prepared with the same amount of sand slope and coniferous humus.

Fertilizer application

Like fertilizer, timely fertilization can promote flower bud differentiation, bloom more, apply leaf fertilizer twice in spring, apply compound fertilizer every half a month from the end of June to the end of June, promote the formation of flower buds, fertilization is mainly phosphorus and potassium fertilizer, appropriate amount of nitrogen fertilizer. Cake fertilizer can be applied once after cool autumn to enrich flower buds. From anthesis to defoliation, topdressing was applied for 2-3 times. Apply thin horseshoe water again before winter to provide nutrients for flowering.

Matters needing attention in summer plum culture pay attention to the control of diseases and insect pests

There are mainly scale insects and aphids, black spot and anthrax, especially in high temperature season.

Pay attention to the wind

Chimonanthus przewalskii is afraid of the wind, so it is necessary to choose a leeward place for open field cultivation. If the windbreak is not in place, the leaves will rust due to mutual friction. If exposed to the wind in the flowering period, the bud is not easy to open, the petals will not stretch, and so on.

Timely pruning

Chimonanthus chinensis has strong branching power, and timely pruning is beneficial to promote more flower branches to germinate and blossom more. It is suitable for pruning after the flower fade to before the leaves, usually between March and June, and stop pruning after July. Cut off disease and insect branches, withered branches, cross branches, over-dense branches, etc., annual branches retain 2-3 pairs of buds at the base, cut off the upper branches, in order to promote branches, after the new branches grow two or three pairs of leaves, they will be coring once.

Matters needing attention in the culture of summer plum I. Control of diseases and insect pests

The main insect pests of summer plum are scale insects and aphids, and the diseases are black spot and anthrax, especially in high temperature season, so it is necessary to strengthen management in summer.

Second, pay attention to the wind

Chimonanthus przewalskii is afraid of the wind, so it is necessary to choose the leeward when it is cultivated in the open field, otherwise the leaves will rust due to mutual friction. If the wind is in the florescence, it will lead to the bud is not easy to open, petals will not stretch and other phenomena, so that the flower plant as a whole is not coordinated and beautiful.

Third, timely pruning

Chimonanthus chinensis has strong branching power, and timely pruning is beneficial to promote more flower branches to germinate and blossom more. Flower branches are usually pruned between March and June and stop pruning after July. Pruning flower branches is mainly aimed at disease and insect branches, withered branches, cross branches, over-dense branches, etc., and cutting off the upper branches is to promote branches.

The above are the breeding methods and matters needing attention of Xiayamei arranged by the editor. I hope you can also raise fresh, elegant and beautiful summer plum after reading it!
