Overlapping Succession Planting

I’ve read books and information on intensive gardening techniques. Many talk about succession planting, in which you grow one thing after another as a way to increase the productivity of your garden through utilizing that space more efficiently over a season by not letting the space stand idle.

Succession planting is a great idea and something I sometimes do, though personally I try to follow something a little more intensive, which I believe further increases my yield. I try to overlap my plantings. So, while some of my garden finishes their season I have other garden plants sprouting and getting ready to fill in to take their place.

You can see an example of this in this picture I took this weekend.

 

In the picture you can see garlic plants that I overwintered, which will be ready to harvest near the start of June. A couple of weeks ago I planted edamame beans interlaced in-between the garlic.  The edamame beans are still small sprouts. By the time I harvest the garlic, the beans will be medium sized plants.

By overlapping my plantings I don’t feel like I impair my plants growth since the initial stages of growth of the new plants have very little impact on the previous plants.

The challenge with using overlapping succession planting as part of intensive gardening is the strain it puts on the garden fertility and difficulty in amending the soil. In true sequential succession planting it is easy to amend the soil in-between plantings with compost or some sort of fertilizer, however if there are always plants present in that location, you don’t want to be dumping compost on top of them. I assure you that lettuce and compost don’t make for good salads.

I’ve come up with a couple of solutions to the challenge of maintaining or restoring soil fertility. The first one being that I tend to use some sort of beans as one of my overlapping plantings, since they are nitrogen fixing and increase the fertility of the garden soil for the next plants. In the picture and example above, the edamame beans are a kind of sweet soybean, which have the nitrogen fixing quality to them. I also tend to stop overlapping my plantings for at least one harvest of the year, so I can top dress with compost before continuing. Due to plants being harvested at different times, I have to do this in a patchwork way in my garden. Winter tends to be the best time for me to do this.

From an aesthetics perspective, I think something growing in my garden is a much more pleasing sight than empty areas of dirt, so if I can keep things visibly present in my garden I feel my garden is more beautiful and more of a personal delight.

I have probably more than 1000 square feet of vegetable and herb garden space, so it is a real challenge for me to maintain truly intensive and overlapping planting regimes throughout my garden, but it is something I continue to work on and keep in mind.
