II. How To Grow Cabbage From Seeds Outdoors?

You can directly sow this plant seed outdoors or start the vegetable seed indoors first. But it’s easier and safer to grow it in your garden straightly. Then, you don’t need to prepare too many types of equipment. Let’s check this detailed operation procedure from the best time for growing cabbage from seed outdoors below.

2.1. Time to start seed

The first step is scheduling. You must select the best day to start the seed before transplanting seedlings to the vegetable bed. 

• Spring frost crop: You should start seeding 8 to 10 weeks before the last frost.
• Fall crop: You had better sow direct in the garden in midsummer. 

Mark the date on your calendar and prepare seeds and equipment for sowing work. Besides, you can watch the weather forecast before starting seeds and sowing. Weather conditions like temperature and rainfall hugely impact the germination rate when growing seeds outdoors.  

2.2. Soil Preparation

The second step is preparing vegetable seeds, soil beds, PPE, and tools. PPE helps protect your hands when working with soil and fertilizers. Follow these steps to prepare plant seeds and the soil bed in your garden.

1. Take dried seeds out of the storage and bag and let them cool down to room temperature. Remove dead and infected seeds. 
2. Break big soil clumps.
3. Remove rocks, debris, dried tree roots, and branches.
4. Add fertilizers or composts to fertilize garden soil.
5. Level the soil surface.

Soil preparation is a crucial step. Creating a good soil bed to nourish vegetable seeds determines the germination rate. Vegetable seeds need suitable temperature, moisture, and oxygen to sprout perfectly.  

2.3. Sowing Cabbage Seeds 

Start to sow cabbage seeds when the soil and vegetable seeds are ready. Sow this greenery seeds outdoors according to the following steps. 

1. Create a small hole in the soil bed with your finger. It should be 1.3 cm deep. Keep a 25-centimeter space between two holes. Don’t forget to wear PPE gloves. 
2. Put 2-3 cabbage seeds into the hole.
3. Cover a thin layer of soil over the seed.
4. Use a watering can to water the soil bed. Keep the soil moist but not sogged.

You can use an irrigation system to water the seed slowly and gradually. Avoid flushing water over the soil and seed. Make sure the soil is still airy to ensure airflow and oxygen supply. Cabbage seeds often sprout at 18 to 24°C. 

2.4. Caring & Transplanting

Keep the soil moisture and oxygen rich enough for seeds to germinate. You can cover the vegetable bed to protect plant seeds from heavy rain. Cabbage seeds often sprout after 8 - 14 days. Transplant seedlings when two or three seedlings grow from the same hole. 

Only transplant the young plant when it’s 10cm tall and has 4-6 leaves. It often takes the young plant 4 - 6 weeks to be mature enough for transplantation. Maintain the space between vegetables to let them develop heads.
