Spinach is very easy to grow in containers.If you are thinking to start your own kitchen vegetable garden Spinach is the best bet. Spinach seeds are easily available at any garden center. Spinach doesn't need full sunlight,it can be grown in partial shade. Corner of balcony or window where you can get few hours of sunlight is perfect for spinach.
I have used a plastic planter for growing spinach. For potting I have mixed soil with coco peat and vermicompost. It is best to sow the spinach seeds in rows few inches apart from each other. Do not over water the plant after sowing seeds. Seeds will germinate in 4 to 5 days (Be patient if it takes longer than that). In few weeks you can enjoy the home grown spinach.
You can harvest Spinach in 30 to 45 days after germination. Best thing about spinach is you can harvest the matured leaves and let other leaves grow so you can get continues supply. As you can see in the below picture I have harvested some of the spinach leaves and others where ready in a week.
I have used two big pots for growing spinach, you can see seeds germinating in second pot. In this way i can have continuous harvest.
Fresh Spinach is ready for a salad or may be Pakoda's :-) (Yummy !!!)
Its really easy to grow spinach, give it a try. Nothing can beat the freshness of home grown vegetables.
Happy Gardening to you :)
