Cautious Cleanup



Wednesday, October 17, 2007

5 AM and 26.7 degrees here on the hill. This was the kind of temperature I expected a day ago but there's no doubt it's here today. The lawn grass is white and crunchy as I walked Karl the Wonder Dog. The air is crisp and serves as a reminder not to go too far from the back door without a jacket. Karl didn't like cold feet and he headed back to the house with great speed. He can go back to bed but I cannot.

This is the time of year for fall cleanup. It is not necessarily a great sport but one that gardeners accept. Part of my problem is where to start. The Mad Hatter told Alice in Wonderland, "Start at the beginning and when you get to the end, stop." I need a Mad Hatter that says "Start here, sir."

There are a few cautions I suggest to anyone, regardless of where you start. I think they are worth a little consideration. First, put on a good pair of work gloves and keep them on as you progress. Gloves can be like socks if you're not careful and then you have several pairs of lefties or righties but no pairs left. I've ended up at times wearing two different gloves and folks know immediately that I never followed my own suggestions.


One of the nicest annual plants in my book is cleome. I have been growing it for several years and I can't start summer without it. Actually all I do is stop at a greenhouse and buy a couple flats and Gail or Michelle get it into the ground. Although there are many varieties out there now, I always buy the taller variety because I like it interplanted along the split rail fence where all the plants are 2.5 feet and up to 6 feet tall.

Cleome is a good plant because it keeps growing upward and it blooms as it grows. As the individual blossoms fade, a long slender seed pod is formed, adding interest to the overall plant. The plant does reseed but the soil has to be closer to neutral than ours is.

The part most don't know about cleome is that it has a good root system and invisible thorns on the lower stalk. When a gentle tug from the mid-plant doesn't free it from the soil after a hard frost, many people bend over and grab tight and pull in one, quick, thoughtless process. That's fine with good gloves but if you're not careful you'll turn into a sophisticated expletive machine spouting nasties as the thorns prick your hands. Don't try to figure out where the thorns are, just wear good gloves and don't forget.

Cleaning up the garden means cutting down plants and getting them out of the garden. This slows down the spread of disease and eliminates places for the bad inspects to lay eggs, hide and winter over, etc. Some people are big on composting and they try to move everything to the pile. I disagree. Here's an example.

Last week on a local television station, fall clean up was mentioned. The host showed how to do some things and specifically talked about cutting down garden phlox even if they are still blooming. He suggested cutting them to 3"-4" and throwing the stems into the compost pile. That would be a "do not throw" to me.



Modern day phlox have been bred to be more resistant to mildew and other fungal problems but many New England gardens have older varieties which have been passed down. As lovely as they are, many are mildew magnets as these pictures show. These were from a nice lavender unnamed variety (that means I don't know the name!) The older whites are even bigger problems, especially during summers like this one with cold, wet weather early on and into July.

I wouldn't necessarily recommend eliminating them if you have a place at the back of the border or far enough away that the foliage can't be noticed ....but...if you can afford replacement, give it some serious thought. In the meantime, do not put this diseased material in your compost pile. In the first place the stems will take another dinosaur age to break down and the fungus will not cook away no matter how hot the center of your pile measures. Let's just say that when you do your garden clean up, think about where to put diseased materials. Whole hosta plants with virus and lilium stems covered with botrytis are other examples.


Along with plant problems at clean up time, I try to remind people about one insect here in New England. My guess is that it's prevalent in many places now as insects are spreading with ease I don't even want to talk about. This is the short winged blister beetle. It is obvious this time of year. I have been noticing small ones in the half to three quarters of an inch size in the grass now but as they mature as in this picture, they'll be an inch and a quarter long and fat. Blister beetles might attract you to pick one up and look it over or show it to someone. Don't. The name says it all and the blisters you will probably get in a day or so will be a bad memory. Just like poison ivy, not everyone is affected but the fact is the per centage is high so just don't do it. Look with your eyes and leave it at that.


I've got to get going to my other world of work right now but if the weather is favorable you might want to start some garden clean up today. Start at the beginning and when you get to the end, stop.

Insect Recollections


Saturday, January 20, 2007

7.7 degrees here at Vermont Flower Farm. The temperature is dropping as the afternoon progresses. The wind has been constant since daybreak but now there are stronger gusts which pick up the fluffy white snow and blow it into disorganized swirls. It's almost like looking at a National Geographic movie of the arctic.

I've been to the platform bird feeder with fresh seed twice since breakfast. As the sun peaked out this morning, the Juncos were here when darkness was just breaking. Then an abundance of blue jays arrived, 6-7-8 of them in noisy conversations I cannot understand. Chickadees flirted in and out and since then its only been Juncos. My guess is that the blue jays will be back by late afternoon to stock up on corn and sunflower seeds to provide caloric warmth through the night.

Yesterday I was looking at garden blogs and up came May Dreams Gardens. From there I checked out Carol's other blogs, stopped at her Hoe and Pictures page, and quite by accident started a circuitous, bunny-hopping search that took me past bed time.

There was a picture of an Imperial Moth, which I had never seen before. Now many of you know I'm very interested in hostas and as a result I found myself at a New England Hosta Society annual meeting one time in West Bridgewater, Massachusetts. Like all the flower societies, annual events usually include a fund raiser auction and this one was no different. One of the hostas on the block was a fine specimen of Mildred Seaver's Imperial Moth. What was better was that Mildred was there herself. What wasn't good was the thing raised a lot of money and my poverty became apparent somewhere around $50 with the bidding still going. Since that day I've probably added a couple hundred hostas to my collection but still don't have an Imperial Moth.

As I continued reading Hoe and Garden I was interested in a link named Whats That Bug.When you're out in the garden most every day, you unknowingly train yourself to recognize details that others might miss. New insects are always on my radar so a website that could help on the identification end of things was a welcomed find.

Years ago I found these metallic blue-black insects in the grass along the potato patch. They always seemed to be in 3's or 4's. I remember getting down in the grass one time to look them over and recall thinking that they would make a good model for one of those creatures in the Star Wars movies. The color is impressive but the antennas and body dimensions are really neat. I kept thinking some computer loving kid could use a name generator and come up with a 12 syllable name no one could pronounce but everyone would love. For me, I just wanted to know what this bug was and which of the flowers I admire that it ate. The website got me started.

The bugs in the top picture are the Shortwinged Blister Beetle. A common name is the oil beetle, no doubt because of the blue-black coloration. My search determined there are several blister beetles out there but I probably have this one right. If not, rest assured someone will remind me of my error.

Oil beetles are often hanging upside down and their size makes you want to right them but that's the wrong thing to do. As with anything in the wild, plant or animal, if you don't know it well, don't be messing with it until you do. Blister beetles get mad if they are touched and they excrete a caustic chemical from their leg joints. The outcome for the intruder is...you guessed it....blisters, and not very nice ones at that. Not everyone is affected adversely but is makes no sense to try first.

As I continued on with Whats That Bug I was pleased to find another insect that I had been searching for. I have no aspirations of being an entomologist, and ever since Mrs. M. made everyone wear a toga and eat weird food in Latin IV, I've never had an interest in going that route to figure out what I'm looking at. What I need is easy descriptions and clear pictures. The end.


My second "mystery solved" turned out to be a Pelicinus polyturator. That would be a Mrs. Pelicinus because the Mr.s are apparently in hiding and difficult to find in the northeast. This is an unusual wasp, glossy black coloration with nice antennae and a long tail, specially evolved for sticking into the ground and directly into June beetle grubs. To keep its energy levels up while hunting for grubs, it drinks flower nectar. This particular one I found on a hosta leaf en route for some blooms but the previous one I located was on a Trillium undulatum in late August.

Finding a website to assist in identifying insects is not difficult to do but this one worked well for me. These two insects will have more interest to me in the future and I'll be able to share what I have learned with other gardeners. Some may get blisters from raking too much without good gloves but blisters from the blister beetle just won't happen if we remember what we've learned.
