Fertilizing the Cherry Tomato Raised Bed

The 4 Sweet Baby Girl Cherry Tomato plants that I grew in my biggest Raised Bed have finally given out. This is roughly the same time as last year that the Cherry Tomato plants died (see this blog entry)

I spent about 2 hours removing the plants and taking down the Texas Tomato Cages.

The picture below shows how the Raised Bed looked like after I had cleared everything out.

One of the reasons why my Cherry Tomato plants grow so well and produce so many tomatoes is because I replenish the soil every year. I put natural fertilizer and manure into the Raised Bed and let it compost for 4 months, so the plants have access to a lot of nutriets.

This year, I am using Alfalfa Meal as my main natural fertilizer. Last year, I used Soybean Meal. Soybean Meal is richer (N-P-K ratio of 7-2-1) than Alfalfa Meal (N-P-K ratio of 3-1-2), but costs almost 1.5 times as much. With the recession, I wanted to save a little money and used Alfalfa meal instead.

I buy my Alfalfa and Soybean Meal from Kruse Feed & Supply in La Habra, CA. A 50 lb bag of Alfalfa Meal costs about $17 from Kruse Feed & Supply. A 50 lb bag of Soybean Meal costs about $25. I typically use about a quarter of a 50 lb bag to fertilize this Raised Bed.

The picture below shows the Raised Bed with a layer of Alfalfa Meal on top of the old soil.

I put a layer of newspapers (see picture below) on top of the Alfalfa Meal to prevent weeds from sprouting.

Next, I put another layer of Alfalfa Meal on top of the newspapers.

Lastly, I put a thick layer of composted Steer Manure as the final layer. I used 10 bags of 1 cu feet composted Steer Manure. I bought the bags from Home Depot for about $1 each.

The picture below shows the final result. You can see the soil is several inches higher than before. I always put the soil up to this level every year, so you can see how much soil is "consumed" each year. I don't step on this Raised Bed, so the soil loss is not due to compaction.

  1. Growing tomatoes in the same location every year may lead to nematode problems. How do you deal with them?
