Planting Peas, Carrots, and Radishes in a Raised Bed Garden
It is March 20th. It is time to plant the cool weather crops in Maryland (Zone 7). I amended my raised beds with peat moss. I will prepare them for the different seeds and use a mix of peat moss (moisten!) and composted humus and manure. Do not moisten the composted humus and manure. You won't like the result. The peat moss gets moistened, and the latter is added.
Step One: Add in Some Peat Moss and Moisten It
You can see the moistened peat moss in the container.
Step Two: Add in One Whole Bag of the Composted Humus and Manure
Mix it thoroughly in with the moistened peat moss. Break up all the clumps. You will use this to amend your seed planting areas.
Step Three: Plant Your Seeds. In This Case, It is Peas
The peas I am planting are stringless and called Goliath. They will grow vines over 4 feet. I am NOT going to use the composted mix to plant the peas. Peas fix nitrogen themselves. If you look closely, you can see I put the peas in about every 2 inches to 2 1/2 inches. You can try later. In a raised bed, because of the deep, loose soil, you can plant seeds closer together. The depth of loose soil means less competition for root space. I put in 3 starting posts to string later, so the peas can grow up them as they mature. I pushed the seeds down to 2 inches with my finger and covered them. Peas are done.
Step Four: Plant Your Seeds. In This Case, Carrots
I have clay soil. Even though I use raised beds and loosen the soil to a good depth, the clay is heavy. Heavy soils challenge carrots. You can buy carrot varieties that help with this. I bought a variety that only grows 6 inches. I cleared a 10 -12-inch-wide furrow the length of the plot. I use sticks to temporarily mark off my plantings.
Step Five: Prepare the Planting Area for Carrots
Carrots grow deep, they are one big root. I added dried peat moss. Â I am not using a lot of dried peat moss, and it gets worked down deeply with a hand shovel to at least another 12 inches. In this case, the dried peat moss will have plenty of time to absorb water. I then added the composted humus and manure the length of the shallow furrow.
The composted material got mixed to a few inches and was smoothed out.
Step Six: Planting the Carrot Seeds
The seeds are hard to see. I planted 2 seeds per spot and three spots across.  You can see the spots with my fingers. So... three spots of seeds width-wise in the furrow and space them about 2 to 2 1/2 inches apart. No science again. The work you did to loosen the soil to depth, lets them grow with little competition.  I started the next row, of three spots, about 2 inches from the other seeds. Work your way down the whole row. You WILL have to thin them to one plant per spot if more than 1 seedling emerges.
The tips of my fingers are one spot each. There are 2 or 3 seeds in a spot. Each spot will have to be thinned to one plant if more than one emerges. Â Do not stress about the spacing... 2 inches in either direction is fine. Just don't forget to think. You might even go 4 across if your furrow is wider.
Step Seven: Plant Your Seeds. Long Radishes Are Planted Like Carrots
Repeat the above for radish varieties like White Icicles. Any radish that grows 4 plus inches should be treated like a carrot. For a review... here are the furrow stages.
Three stages to long root crops like carrots, long radishes, and parsnips.
Step Eight: Plant Your Seeds. Standard Round Radishes or 2-Inch Radishes
Dig out the row with your hand about an inch deep or a little more. In loose soil, your seeds can be a little deeper than the package suggestion. Remove clay clumps.
Step Nine: Planting the Radishes
One radish seed, 1 inch apart, down the length of the row. You can think them as needed. The thinned radishes are great in salads. I put some composted humus down and then put the seeds on it. I covered them with the surrounding soil, with varying depths of 1/2 inch to 1 inch. Again, don't stress over being exact. I used poles and stakes to mark my plantings.
