Rake the fertilizer or compost into the soil. Create mounds that are at least six inches tall, as the collards can have roots that reach about two feet in depth.Space the rows at least two and a half to three feet apart.Sow the seed at a depth of 1/4 of an inch. Keep soil moistened. Seeds will germinate in about 7 days.
Once the plants reach about 6 inches tall thin them out to a spacing of at least 1 1/2 to 2 feet apart.If you notice the leaves on your collard plants starting to have a paler green color to them instead of a rich deep green color, you will need to add a side dressing of fertilizer to each row of plants.Add only one teaspoon of fertilizer per plant, mix the fertilizer into the soil well and water in. This may need to be done every 6 weeks as the plants grow.
Begin harvesting the leaves from the plants when the plants reach about 10 inches tall. Harvest from the bottom of the plants,discard the leaves at the very bottom (the first 3-4 leaves), as they can be tougher, then harvest the others,leaving the upper leaves on the plant.You can also choose to harvest all at once, by simply cutting the plants down when they are about 12 inches tall.----------------------------
Growing Mustard Greens:
------------------------Mustard greens are a fast growing green that pack plenty of nutritional value.Being ready to harvest in about 45 days from seed sowing.
Mustard greens can be eaten either raw or cooked.They add a bit of pep to the salad, and are a great winter time green that freezes well for use in soups, or as an accompaniment to meats like pork chops,ham, and other hearty winter time fare.
Mustard greens are a "cut and come again" crop, meaning you can cut what you need from the plants as you need it, through to winter frost.
----------------- Direct sow the mustard seed into the garden. No need to make rows for the mustard greens really, as they can be grown rather close together.You can even create a raised bed specifically for this variety.
Sow the seed at a depth of 1/3 to 1/2 inch deep. Allow to grow until the plants reach about 2 inches in height then thin to 3 inches to 5 inches apart.
