We bought only a dozen everbearing strawberry plants in the early spring, and they have reproduced themselves over the summer to approx 50+ plants and are still spreading. We are very pleased with their growth rate this year!
The new asparagus plants are only about 8-10" tall but we have high hopes for them! We have planted approx 50 new babies of each, asparagus and strawberries, giving them lots of mulch and room to grow.
This is our current asparagus, in September, with cardboard around the base, which we will top with other compost as the winter wears on. Soon it will be time to cut it back and mulch for the winter.
This is what happens when you make a strawberry bed where the peas were earlier... Oh well, we'll have another late crop of peas, I guess. We do like gardening surprises!
The layers on top of the cardboard can consist of any organic material that does not contain any protein (fat, meat, dairy or bone). Old hay, straw, leaves in the fall (rescue these form the curbside of friends and neighbors), kitchen compost, sawdust, a little wood ash, manure, peat, and any other organic material you can find. Materials will vary in each individual's garden according to what is available locally. I have heard that seaweed works very well but you may need to rinse the salt out first.
When you're planting a lasagna garden, no digging is required. For transplants, simply pull back the layers of mulch, drop in the plant and pull some mulching materials back over the roots. Sowing seeds is easy, too. Sprinkle a little finished compost over the area you want to plant, sow the seed, and cover it with a little more of the finished compost. Press down on the bed to secure the seeds and water thoroughly.
Lasagna gardening is definitely the way to build vegetable or flower beds! We use this method for both. While we do still use a tiller for the vegetables, we are slowly moving away from it. Because it uses no power tools, heavy equipment or expensive commercial additives, lasagna gardening is an easy way for people with space, age or physical limitations to maintain garden productivity.
