Space the seeds 4 cm apart. Space the rows at a distance of 30 cm. Plant at a depth of 0.5 to 1 cm. Spinach likes full or partial shade. After sowing, water the seeds adequately. The seeds come in a bag containing approximately 15 grams. This is enough to sow 8 square metres.

Spinach seeds require no prior treatment. If you sow a row of spinach every other week you will always have some fresh to pick.
How to Sow
Spinach belongs in the garden (although the cold frame is handy too). Sow just where you want them to grow them. Replanting is not advisable.
Spinach should be grown in a good fertile soil that retains moisture well and is full of nitrogen and minerals. Spinach really hates it to be dry.
Early harvest (April): usually from January in a cold frame.
Spring harvest (May & June): sow continually from March through May.
Summer harvest (July & August): sow April-August.
Autumn harvest (September & October) sow end of July until mid-September.
Winter harvest (December through until April) sow from October onwards. In a cold frame, greenhouse or plastic tunnel.
Sow outdoors in full sun from April through September.
Loosen the soil with a fork to about 30 cm deep. Make a straight grove about 1 cm deep. Always label your rows! Mix the fine seed with dry, sharp sand and sprinkle along the row between thumb and forefinger as thin as you can. Cover the seed with half a centimetre of soil, press carefully down and sprinkle with water. Extra rows should be 20 cm apart.
The cold frame can be used to sow from January through March already in the same way as described above. Under no circumstances should the soil be allowed to dry out.
Spinach likes to be kept moist. Water extra if it seems even a little bit dry. Keep the bed free of weed and your spinach should thrive. Try to prevent your spinach from bolting (forming flower stems). You will notice a sudden growth spurt and flowers will then appear. This usually happens in the summer but can vary per variety of spinach.
Bolted spinach is still edible but tastes more bitter so harvest your spinach before this happens.
The only way to harvest your spinach is to cut the leaves close to the ground. You can harvest about 5-6 weeks after sowing the seed.
There are so many different varieties of spinach nowadays. Some are more suitable for early harvests, others are better for late and some are even good for all year round picking. It all depends on how susceptible they are to bolting.
If you plant an early variety in the summer, it is liable to bolt immediately - not what you want! So order the correct spinach for the time you want to be harvesting! You can extend your harvest time by two months if you grow spinach in a cold frame or greenhouse. Spinach doesn't form a head so it's really fast. It can also withstand quite an amount of frost.
All spinach is Spinacia oleracea and is classified under Amaranthaceae.
There are actually two types of spinach seed, pointed seed and round seed. The pointed varieties have seed with two 'spines and the leaves are also pointed. These make the best 'earlies'. The round seed varieties have rounded leaves and are usually used for later harvesting.
