Is lily suitable for planting in summer?

Recently, flower friends often ask if online naked balls can be planted in summer. This question is hard to say. Here's my explanation.

Question 1: What is a frozen ball?

Frozen ball refers to the seed ball that can still germinate after being treated at a low temperature of 4 degrees and breaking dormancy for several months. Imported lily balls are frozen balls, whether in spring or autumn. This does not mean that it is suitable for planting in summer. Only businesses in Suqian and other places will sell the old cut lily pills used by Daejeon all the year round. They are natural balls and the germination time is unpredictable. Pre-rooting treatment of lily planted in frozen summer.

Question 2: What's the difference between these balls and those in August last year (autumn lily)?

Last year's autumn lily (also a frozen bulb) was pre-rooted at 12 degrees for two weeks, and germinated about 5- 10cm. It was sent to everyone for planting at the end of August and the beginning of September, which eliminated the influence of high temperature in summer on the root growth of lily as much as possible. However, in June, the bulbs were bare and did not take root in advance, which was suitable for planting in a professional cut flower production greenhouse with air conditioning (cooling facilities). Not suitable for amateur flower market. My personal guess is that the merchants saw that the spring lilies sold well this year, and temporarily added a batch of goods, and the varieties of Otawa spring lilies were almost the same.

Question 3: Why don't lilies grow in the hot season?

1. The suitable temperature for lily stem rooting (an important root system that absorbs nutrients above bulbs) is about 12 degrees. Generally, the soil temperature (not equal to air temperature) in spring and autumn is close to this range. The development of stem rooting directly determines the flowering quality and rejuvenation.

2. Most lilies are not resistant to high temperature, and their dormancy temperature is extreme. If the temperature stays above 35 degrees for a long time, especially for Dongbei, it is easy to cause forced dormancy. Lily can't stand extreme high temperature, especially in bud stage and flowering stage. The high temperature during flowering will make the flowers wither quickly. Lily rots easily in hot, humid and sultry weather.

Spring lily has entered the ball-raising period at this time, so it can be shaded and watered properly to avoid premature dormancy and rotten balls. However, the summer lily planted at this time will inevitably face the trade-off between light and temperature (high light-high temperature-poor growth).

Question 4: Do I buy these balls or not?

If you are not particularly eager to grow lilies and live in a typical summer climate zone (the temperature is often higher than 35 and the humidity is high), I suggest not buying them. If it is extremely urgent, you can try a small number, mainly heat-resistant iron guns, LA and OT. Recently, the highest temperature is around 25 degrees, so flower friends who are not very harsh on local summer can rest assured to try.

Question 5: What should I do if I have already bought it?

If reserved, please bury it 8cm- 10cm when planting. Proper deep planting can reduce the influence of high temperature, avoid sunlight before germination, and maintain the lowest temperature as much as possible within two weeks after planting (it can be watered with cold water or even ice water). After the leaves are displayed, they will be exposed to sunlight and maintained normally until they bloom. If the temperature is too high, pay attention to shading in the afternoon to avoid exposure to western sunshine. If it goes well, they can also blossom in August.

Add: Actually, it's ok to try, but don't get too high hopes and spend money indiscriminately. If everyone's lilies bloom well at the end of August. . . Forget it, practice makes true knowledge!
