Sustainable gardening

Pest Patrol

It’s that time of the year–although in the garden, as soon as there is green, any time of the year is time for insects.

One thing I am always sure to talk about when I lecture is insect life cycle. Many insects in my part of the country can simply be ignored. This may not be possible in warmer parts of the country where ignoring an infestation just permits continuing infestations.

But in my cold climate, most insects only have the ability to have one life cycle–or one chance to breed, reproduce, chew and die.

If I had to worry about repeated infestations, I would surely have to be more proactive.

So when I see these rose sawfly larva on my rose leaves, I know that they are going to disfigure the leaves and then they will pupate and become the tiny wasp-like insects that they turn into and fly away and that will be that.

You can see the little larva here on the leaf. While it looks like a caterpillar, it’s not: it’s a sawfly larva. Why am I making this distinction? Because I could spray bT all day on this and it would have no effect. BT only affects caterpillars. Know your insects.

It’s the same with the hydrangea leaftier. Most years they are so minor that I just ignore them completely. If an infestation seems to be getting out of hand, I cut them off, bag them up and they’re gone. That solves the problem for several years. The moth that this caterpillar becomes is an unremarkable tan and brown–nothing worth writing home about and certainly nothing worth poisoning a plant or the earth over!

But the point about both of these insects is that their caterpillar stages are relatively short-lived. True, the rose sawfly can cause quite a lot of leaf disfigurement in a short period of time, particularly if you can’t tolerate that look.

But I will repeat: is it worth poisoning your earth, your plants and possibly yourself over? Catch it early and the sawflies succumb nicely to being sprayed off with a hose. If you need something stronger, some insecticidal soap or a great OMRI registered product called Rose Pharm works.

But I’d never resort to anything stronger than that. And even then, because those products will affect the pollinators, I would be extremely careful with them.

Planting for Pollinators

gardendaze2 Comments

I’ve done a lot of posting over the last week or two about what I’m planting–my herbs, both for me and for the pollinators, the annuals in the herbs garden, my indoor succulent corner (which no pollinators can get to, of course, unless they accidentally get inside the screened porch–and why would they want to?

As I was thinking back over this and thinking forward to Pollinator Week, which occurs this year June 17-23, I realized that for all my talk about native plants, I hadn’t planted any native plants.

Is this a catastrophe? No. I already have a lot of native plants in my yard. But as someone who talks a lot about native plants, I do like to add them when I can.

But one thing I didn’t do this year was add any trees, shrubs or perennials–the sorts of plants that are native plants. So that’s why no natives this season.

So should I consider my whole season a loss? I guess that depends on what you are trying to accomplish. This season, I am lucky that I can get a little gardening in. I am hoping to be able to harvest just a few tomatoes and some green beans–and to have some fresh herbs to cook with.

I’d like a few pretty flowers to look at and I have chosen those flowers with pollinators in mind. In the past, I have seen both hummingbirds and sphinx moths on impatiens so I chose those for a semi-shaded spot.

For the sunnier spots, I chose annuals in colors of blue and yellow, primarily to attract bees and butterflies. One of the containers has some lantana, which I know the butterflies in my area love.

My earlier spring container, which was a Wordless Wednesday photo, was violets and alyssum. I have watched honeybees and smaller bees on that until I moved it to a shadier spot where I don’t get to observe it so readily.

So I am not feeling too sad about the gardening season so far. I am just hoping that the deer don’t eat the green beans, as they have in some years. Time will tell!

Re-Cycling

Trash? Or someone else’s treasure? For a couple of years now the Spoiler has been whining that my flower pots were taking over his garage–and it is his garage. I have to park outside, under the old trees, even in snowstorms, because he has more vehicles and accoutrements than our garage will accommodate. But that isn’t the topic of this post.

So after moving the house plants and deciding that I really did have far more pots than I would ever use again, I agreed that we could put them out for the neighborhood version of free cycling. What you see is about half of what’s left.

At least I know that they will go to good homes. Presumably you don’t stop for flower pots unless you need them.

The Freedom Lawn

We’ve grown a little too obsessed with perfection. It’s everywhere we look. If we turn on the television, all we have to do is tune in to the commercials to see that we are being sold a bill of goods: buy the perfect vehicle, or clothes dryer, or clothing, or grass seed and we too can be perfect (and don’t even get me started on the pharmaceutical commercials!)

What exactly is a “Freedom Lawn?” Well, like the name suggests, it’s a lawn that avoids inputs–so no fertilizer, pesticide, irrigation or other input beside mowing. So what happens?

20190429_173134

As you can well imagine, nature happens. Wildflowers–or to the uninitiated–weeds grow. And granted, not all wildflowers are welcome. For example, we have far too much plantain in our lawn. But it’s there and it’s not terribly unsightly and were we motivated it’s fairly easy to remove with a stand on step weeder–so clearly we’re not terribly motivated.

This strip is right next to the driveway as you might be able to tell. Plantain loves compacted soil. So we would be working at cross purposes by trying to remove it and grow grass in a spot where folks keep driving.

Dandelions are creeping back in, I notice. That’s one thing that doesn’t bother me at all. If you’re a “lawn person,” they drive you crazy. If you’re a pollinator person, you rejoice, because they are one of the earliest flowers for pollinators. Just deadhead them before they seed. I think I can still count them on 2 hands so they’re not a nuisance.

20190429_173017

And violets. I love the violets. I would have an entire lawn of violets if I could–again for my pollinators. This lovely little one is a species of viola moderate that I planted called ‘Freckles.’ The photo at the top of the post afe all wild violets.

Certain butterflies will nectar only from violets–why would anyone want to get rid of them? (Again, you can see that I am clearly NOT a lawn person!)

20190429_173041

Ants have naturalized these muscari for me. Maybe you can see why I am fond of ants. They also spread my violets around.

20190429_173634

We used to have much more clover but since my neighbor’s landscape company mistakenly poisoned my property, most of it was killed off. It’s just beginning to return, thankfully. Where the plantain has run amok used to be wild clover. Ah well.

As the season progresses, I get tiny little St. John’s wort coming up–I’ll post that at some point. The plantain blooms. And of course we get more unwelcome wildflowers like purslane and the vetches and oxalis–not welcome to us, but valuable to wildlife like the later nesting goldfinch who love the seeds.

So rejoice and enjoy a more nature looking lawn–and maybe even consider a “freedom lawn.” Your birds and pollinators will thank you.

Earth Day 2019

gardendaze2 Comments

Happy Earth Day! Can you believe that Earth Day is 49 years old? Goodness, neither could I–I had to look it up.

Thankfully, as with all things internet, Earth Day has its own web site so you can check it out for yourself if you’d like.

I am old enough to remember when Earth Day was started (although I am not quite old enough to remember a lot about the first Earth Day–as I like to say, I missed all the fun things about the 60s and got disco for my teen years–sigh!)

But that does make me old enough to have experienced the first great house plant revolution so by now, at least, I am a house plant expert. There are some benefits to age. Just some.

But if we think about how our lives have changed–for the better–since that first Earth Day–we won’t be lamenting so much, I don’t think.

I think back to the pesticides in use in my childhood and teen years–now all of them banned, thank goodness.

We didn’t think about anything like water use, energy use, the type of light bulbs we used, or recycling. And now, most of us have become so efficient at recycling that there’s actually a glut and no market for our recyclables. Wow.

In our gardens, more of us than ever are seeking the least toxic alternative possible. We’re growing our own vegetables and sometimes our own fruits, and raising backyard chickens and bees. Sometimes we have goats or alpacas and even spin our own fleece.

We have come a long way in 49 years. There is still a lot more to do, of course. But let’s not forget to celebrate our successes.

The Eye of the Beholder

I had an interesting thing happen when I was asked about how to control weeds at my last lecture. I began to talk about using low, ground-cover plants as living mulch for weed control and I said that while it was a relatively new idea to the United States, it was being used in Europe for several years and that I had been doing it my house for a decade or more with two different materials–leaves and moss.

The gentleman I was speaking to said, “Moss? Isn’t that something you kill?”

20190414_145353

And while I am just famous for saying that we can’t all like the same thing, I just shudder at that.

20190414_145055

My answer to him was that yes, I had seen the moss-killing products in the aisles of the big box stores, but he might be surprised to learn that moss was actually a living plant, and a very valuable one at that. I told him that if he were to go home and try to buy flats of moss online, he would spend a minimum of $80 per flat and could spend considerably more (that seemed to get his attention!)

20190414_145225

And while I don’t have a spectacular garden of moss-that’s not really my intention, although someday I would love it if that were to happen–but I need to do a lot more than I am doing to make that happen (and probably have a lot more shade and reliable moisture than I do), I do have lots of different species of moss and I just adore them. I encourage the moss whenever and where ever I can. It solves a multitude of problems.

And yes, it makes a great mulch for me as well.

So please, do yourself a favor. Next time you see some moss, don’t just reach for a “product.” Stop to appreciate it–and perhaps put it to work for your as a mulch!

Spring Clean-Up

What?! Dead trees again?! Actually no. Take a look at what’s beneath them. See all those leaves? Every cultivated garden bed in my yard looks similar to that. And it’s going to for awhile yet.

I postpone my spring clean-up until at least May most years. Some years, things happen and the beds never get cleaned out. In that case, I call this “mulch.” Nothing terrible happens to my plants. I don’t harbor over-wintering insects (at least not the bad kind–more on that later) and I don’t have a whole slew of fungal diseases.

20190410_072208

So why–or perhaps more important–how can I tolerate this look–in my garden beds? (Here’s what this really looks like, with some of the spring foliage coming up through it, in my “wildlife garden”.)

It’s pretty simple: These leaves are sheltering all kinds of over-wintering things: good bugs like spiders, over-wintering larva of mourning cloak butterflies. The stems of the upright perennials may be sheltering bees that use hollow stems like mason bees (which don’t sting, by the way). I have ant colonies under here (and you know that I love my ants and consider them pollinators). I have earthworms. I know that I have ground beetles because I see lots of them all summer.

So I ask you–with all that “goodness” going on here, could you put up with some ugliness for a bit into the spring?

Because I tell you, I sure can!
