Zucchini is a kind of vegetable that likes warm environment. When sowing, the temperature should be above 15 ℃, and the climate should not be too cold or too hot. Therefore, the time suitable for sowing is only spring and autumn.
If you want to plant in spring, you must not let it suffer from frost damage. The general areas are around April to May. But if it is planted in the greenhouse, the time can be appropriately earlier, and it is also OK to sow around March to April.
In autumn, the climate in many areas is unstable, and there are often plum rain and high temperature. If so, we must avoid this period, or it will do great harm to it. Autumn is suitable for sowing in late September, and can be carried out until the first ten days of October. If the climate is not too cold or too hot, it is OK to advance it properly.
Before sowing, you need to watch the weather ahead of time. If the weather after sowing is cold or hot, it is not conducive to seed germination, but also the growth of seedlings is not good, and the most important time the plant is also vulnerable to diseases and insect attacks.
