Blueberries turning red in August

There's a lot to be said about doing your homework and learning from the experience of others, rather than reinventing the wheel. In many areas of my life I do learn in that way, but sometimes you have to learn by making your own mistakes.

Intellectually I knew my soil was far too alkaline for blueberries, and while I made some small effort to mulch with pine needles I did not think that the effects of a high pH would affect my blueberries this early on. I was under the impression it would reduce the amount of berries the plants produced years in the future. I have been growing uneasy throughout the summer as my blueberry leaves have been turning gradually redder and now I am forced to admit I should have taken action months ago. 

The pH of a soil will not kill your plants, what happens is that the acidity of the soil affects the plant's ability to take up certain nutrients. Nutrient deficiency leads to weak plants, and eventually death. Since blueberries evolved in areas where soil acidity was higher, they are adapted to take up nutrients in a pH of around 4 or 5. Most other plants seem to like a slightly acidic soil of 6.5. 

My blueberry plants are now bright red and waiting to be rescued. I was able to buy a tiny amount of aluminum sulphate which lowers pH, and I sprinkled it around all of my plants. There was nowhere near enough in the tiny box which was likely for people who own 4 rhododendrons. I ordered 25kg of ammonia sulphate which will be more than enough for my 60 blueberry plants. I read online that coconut coir can also help blueberries in neutral soils, though it didn't seem clear to me why this should be. I happened to have kept half a dozen old bags of coconut coir that were used to grow tomatoes in a greenhouse; I mulched the blueberries with this yesterday. It is my hope that this will help them struggle through this period until I can give them their "medication". 

There you have it, I knew what I needed to do to have happy blueberry plants and yet I needed to see the effect of not doing it before I bothered taking action. This is not a good trait to have, but learning first hand helps the information stay in my brain permanently.

Spring Begins-- Eden's Rise Year 2

After a week dashing off to my orchard every day after work to plant until sundown, Eden’s Rise is now 160 bushes richer. Currants, blueberries, haskaps, and gooseberries were the primary focus of this planting.

Astonishing numbers of flowers are appearing on last year’s Saskatoon bushes and the asparagus shoots are purple undead fingers pushing out from the earth. Rebirth, baby. Along the pathway in the middle of the orchard Crocus flowers bloomed, then delicate blue Muscaris followed.

The thick layer of coconut coir and dried grass mulch that surrounded every tree and bush has now completely disappeared. This could either be due to a natural process called ‘decomposition’, or, equally likely, garden gnomes stealing it as kindling to light their winter fires. Live and let live, but I will need more mulch if I am to combat weeds and weather. Far from last year’s drought, we began this spring with an unprecedented amount of water, with part of Ottawa heavily affected by floods. Who knows what this summer might bring, but mulch is that magical ingredient that promises to save you from everything. I hope.

It is a comfort, as I begin the long and frankly dull process of gathering and spreading mulch, that last year’s mulch is by now incorporated into the soil around my trees. Some of that mulch is now ‘organic matter’, which is extremely beneficial in the soil. Because the particles are tiny, they wildly increase the water holding capacity of your soil. Organic matter releases nutrients to plants over time and improves the structure of your soil. Even if the gnomes steal 90% of my mulch, at least some of it will have some lasting benefits after disappearing from the surface.

A large pile of horse manure waits to be distributed among the plants this spring. Since this will be applied beneath a layer of mulch (to avoid runoff at the next rainfall) I have my work cut out for me getting all of the trees ready. Once the trees are larger, the mulch will not be necessary. While the trees are young and the roots still finding their way it is important to reduce the amount of weed competition. If you think spreading mulch is boring, I dare you to try to pull grass out of an untilled clay field. I can tell you it is no picnic.

Catnip, onions, and strawberries all survived the winter and have already grown a surprising amount. I am pleased the catnip turns out to be a perennial (I did not do my research before planting; beware, it can become as invasive as mint). I planted catnip because not only does it attracts cats (and who doesn’t want an orchard full of cats?), it is said to repel mosquitoes. Maybe this is just another trick from the Catnip Marketing Board but I think it’s worth trying anything that makes such claims.

These are the first stirrings of life after a long winter!

See you soon!

Obsessed, mulch?

Strawberries plants are often mulched. Mulch keeps the berries clean (no direct contact with soil), it also acts as a temperature buffer and reduces moisture loss from the soil to the sun. Best of all for the farmer with a bad back; mulch suppresses weed growth!

Strawberry beds kept tidy with use of mulch

My little field has been fallow for at least seven years. That's seven years of grass growing and dying. Mulch can be expensive for the organic gardener, but for me it was only a matter of raking for 10 minutes to get enough old grass together to cover one bed. 40 minutes later all my strawberry beds were mulched!

Blueberries mulched with pine needles and grass

The result was so good (particularly on the weed side) that I figured I should do this for all the plants on Eden's rise! The blueberries have a mixed mulch of pine needles (to increase acidity) and grass. All trees, bushes, and vines have a small circle of coconut coir mulch from planting day that has now been covered by a larger circle of grass mulch. I am grateful that I began this little project after the first full week without rain. There has been very little rain so far this summer and the field is in the full sun all day when the temperature is frequently above 30 Celsius. The mulch keeps the weed competition away for the base of my plants so when I waddle over with water for each tree I know I am not wasting that water on weeds. Thanks to the layer of mulch the hot sun also loses much of its opportunity to steal the water and the soil does not bake. 

Those are the often praised advantages of mulch, but I enjoy mulch for another reason. Bare soil, as the soil would be if I managed to keep it weed free, is subject to erosion. Anyone who has ever had a passing interest in sustainable agriculture knows that loss of topsoil is a serious problem in areas that are routinely cultivated. Erosion from wind and rain can hit hard on fine soil particles (like my clay soil). Since the soil depth on my hill is only about 1.5 feet to bedrock, every bit of soil is precious. The mulch will eventually rot down and be incorporated into the topsoil with the positive effect that in this case agriculture adds to the topsoil rather than depleting it.

There is always work to be done on Eden's Rise, I will leave you at that! Have a lovely week.
