Fall Leaves: Rake, Blow or Mulch?

fall leaves

Fall leaves certainly are beautiful in this neck of the woods. At least they are while they are still on the trees. Not so much when they cover every inch of your lawn! If they don’t get removed from the lawn, they will smother the grass making it weaker in the spring.

So, should you rake them, blow them or mulch them?

When all the pretty leaves fall from the trees this fall, instead of bagging them to put out on garbage day, use them in your garden as free mulch.  Most leaves, with the exception of oak leaves, break down easily over the winter.  They add nutrients and humus to the soil in your gardens.

In the garden, worms from the soil will draw the decomposing leaves into the soil, improving the condition of your soil, which in turn benefits your plants.  Next spring you can bury the portions of leaves that have not decomposed in the garden, and marvel at how rich your soil is.

The leaves in the garden will also protect your perennials and shrubs, like a warm blanket, from the freezing and thawing cycles that do the most damage to garden plants.  Roses especially benefit from a blanket of leaves around their crowns at the soil level.

If they are small leaves, simply rake or blow them into your garden around your perennials and shrubs, taking care not to bury the smaller plants.  If the leaves are large, run them over with your lawn mower to shred them before adding them to your garden.  Oak leaves especially should be shredded, as they are slow to decompose.  You may have to spray the leaves with your hose once they are in the garden to keep them from blowing back onto your lawn.

Raking Fall Leaves

Raking is the old-fashioned way to rid your lawn of leaves. Some (my husband included) still swear by this method. We use plastic bags saved from new mattresses years ago to haul the raked leaves to a designated leaf (AKA compost) pile. This procedure works well if you have an area to store the leaves. (which we do at the cottage) I don’t mind raking but when we are talking about a huge property, a blower or mulcher is called for in my humble opinion.

The Advantages of Mulch

Mulched leaves are great for your garden.  They are an inexpensive way to amend your soil and protect tender perennials and shrubs from the wrath of Mother Nature over the winter months.  If your soil is really poor, add a layer of composted manure over top the mulched leaves.  The soil in my Kanata (Ottawa suburb) gardens was predominantly clay, so this fall treatment has really helped over the years.  Your reward will be visible next spring and summer when your gardens look gorgeous.

If you don’t have a blower or mulcher, you can run the leaves over several times with your lawn mower, then rake the crumbled pieces onto your gardens or into a compost bin.

Leaf Blowers with or without Mulcher Options

These contraptions also create great mulch for gardens and/or compost bins or piles. I first purchased a leaf blower several years ago, early on in my career of looking after peoples’ gardens and yards. I loved it so much I was collecting leaf-filled yard waste bags from my neighbours’ curbs to mulch. I love mulched leaves in my gardens. So much so that one of my neighbours gives me his mulch too.

As with any brand of leaf mulchers, you must wait until the leaves are dry before you attempt to vacuum and mulch them.  Wet leaves will just clog up the motor, resulting in a loud whining noise.  Wet or damp leaves also make for larger pieces of mulched leaves instead of the incredibly fine mulch. With low overnight temperatures and lots of rain keeping the leaves wet, perfectly mulched leaves were no easy feat these past few weeks.  I found the easiest way around this dilemma was to blow leaves into a single layer in a sunny spot to dry before mulching them.

Another thing to avoid while vacuuming and mulching is twigs or sticks.  They too will clog the motor, not to mention damage it.

Precautions

Most models are quite noisy so earplugs are recommended. The first time I used one without ear protection I wound up with a massive headache.

Although the models I’ve used have all been electric, there are battery-operated or gas-powered, cordless options available. If you are using a long extension cord or several combined (for large properties) be sure your extension cord is a heavy-duty one. According to Copper.org:

An improperly sized extension cord can cause a tool or appliance motor to burn out if allowed to run for too long. It can also cause a dangerous situation if it overheats.

Blower and Mulcher Brands

Toro Ultra Plus

I liked the Toro but found switching the blower to the mulcher tedious. You had to remove one attachment and trade it for the other. This switching back and forth was not only time-consuming but hard on my arthritic wrists.

The bag that held the mulched leaves had a zipper on the bottom to contain the leaves. This zipper was handy, but if you forgot to close it before you started the motor for the next batch, the leaves would fly all over. I did that a few times.

When I graduated to a fancier blower and mulcher, I donated my Toro to the hospice I volunteer at.

Worx Leaf Blower and Mulcher

My next garden toy was made by Worx. I prefer it because you can switch from mulching to blowing leaves with a simple turn of a dial. Very convenient and much easier on my wrists. It too has a zippered mulch bag, so the “don’t forget the zipper” rule applies here too.

Black and Decker

The most recent blower and mulcher I’ve used is a black and decker model. It was given to me by the son of a client after she passed away. I took it to the cottage as I had one at home.

This model is quite impressive although it is now an older model. It seems more powerful than the others in both blower and mulcher mode. This is awesome while you are using it but it means the unit is heavier. I could feel the workout in my forearm muscles the next day. And the arthritic wrists well before that.

You do have to switch between the options by removing and installing the motor component but the process is so simple even I can do it without complaining. There is no zipper on the mulch bag. Instead, you insert the bag onto the mulcher head with a plastic latch. In theory, this works well but the latch seems flimsy, so after several batches of mulch it was getting loose. I’ve noticed the new models don’t have this latch.

Another downside to this model is that it has no shoulder strap on the mulch bag to distribute the weight of the tool as well as the bag of mulch. The other two models had a strap, perhaps that is why my forearm muscles and wrists felt the workout with this one.

Conclusions

It doesn’t matter which method you use to remove the fall leaves from your lawn. Just be sure to do so, your lawn will thank you in the spring with a quick recovery from winter stress. So will your gardens and compost pile if you add the mulched leaves to them.

Spring Cleaning your Gardens and Lawn

spring cleaning

Just like the inside of your home, your gardens and lawn will benefit from a good spring cleaning too. As soon as the snow disappears from your lawn and garden you can start the spring cleaning.

Spring Lawn Care

When your lawn is dry (not spongy to walk on) give it a good rake to remove all the dead grass and leaves. Core aeration is recommended after raking to allow oxygen and nutrients to penetrate into the root system of your lawn, especially if your soil is heavily compacted.(as most lawns are in this area) Core aeration is also effective in the fall, one less thing to do in spring.

If your lawn has a lot of crabgrass and broad-leaf weeds (dandelions) you can treat it to a weed and feed product.  The ones containing corn gluten are particularly effective if used before the weed seeds have a chance to germinate.  I sprinkle corn gluten right on the snow when there is only a small amount of snow left on my lawn because as soon as the snow is gone, the weeds start to germinate and within a few days the crabgrass growth is visible.  

You can also overseed your lawn now (but only if you have NOT applied something for weeds, otherwise wait 6 weeks to seed) by raking in topsoil and sprinkling grass seed on the soil.  This is best done before a rainy spell as the seeds should be kept wet until they germinate.

Clean Debris out of your Gardens

Your gardens can also use a good raking early, but be sure to use a plastic rake and a gentler touch, so tender dormant perennials are not damaged.  Remove all the dead, but still intact leaves, last year’s annual (annuals are plants that you must replant each year) plantings, and the twiggy pieces of last year’s growth on the perennials (perennials are plants that come back on their own each year).  Generally speaking, if the twiggy pieces break off easily with a gentle rake, it is safe to remove them.  

Woodier perennials (lavender, sage, hibiscus etc) need a bit more time to rebound from winter and should not be cut back until new growth is visible. Spring cleaning on those fussier perennials should wait.

Prune Shrubs, Divide and Plant Perennials

Shrubs that bloom in summer or fall (weigela, pink spirea, burning bush etc) can be pruned in early spring, while those that bloom early in spring (forsythia, lilacs, magnolia etc) should not be pruned until after they bloom.

Dividing perennials is best done this time of year too; dig up the overgrown clumps, divide them with a sharp spade, and plant them in their new locations.  Fill in bare spots with new perennials. These jobs can be done as soon as the ground thaws.

Annuals, however, should not be planted until the danger of overnight frost is gone, usually late May in this area.

Amend Your Garden Soil and add Mulch

Once all of my perennials have re-emerged, the weeds and old annuals are removed, and the necessary pruning is done, I like to amend the soil around them with soil, compost, and peat moss. This triple mix product can be purchased already combined.  

A layer of cedar mulch (I prefer dark brown or black) is the final touch, but to prevent your plants from rotting, be sure not to apply the mulch too close to the base/stalks/stems of the plants.

Finishing Touches

The last step in spring cleaning your gardens is to retrieve the outdoor furniture and whimsical touches from their winter storage. Then enjoy the most important part, take a few minutes out of your busy life to sit down, relax and admire your efforts…
