Make Music New York 2018

Last Thursday was June 21 and thus time for Make Music New York. For us, it meant to get treated to a performance by the Nevermind Orchestra. With their fun brass sound, the band attracted listeners of all ages into the garden and to the fence.

The Nevermind Orchestra plays for an audience inside and outside of the garden.

Especially children were enchanted by the music. I witnessed how a little boy would rather listen some longer instead of going out to get ice cream. And a little girl joined the band with her toy instrument.

It was a perfect evening with balmy temperatures. The garden looked lush and pretty after a rainy night. By the time the band had finished its set, the first fireflies came out. Happy Summer everyone!

National Pollinator Week

This blog has been a lot about bees lately, and I will stick with this subject for just a little longer, because this week is National Pollinator Week.
You may know that without honey bees, there would be no almonds, peaches, apples, cherries, blueberries or strawberries in our super markets. Bees need to visit and pollinate the flowers of all of these plants, or there will be no fruit.

However, there are many more pollinators than just honey bees. In fact, in our garden, most flowers are visited by other insects, while the honey bees fly off to richer pastures (right now, to the linden trees across the street).

Over the last few days, I went to the garden in the morning and at night to document which pollinators I can find on our flowers.

Leaf cutter bees. Females collect pollen on their bellies, as can be seen in the top middle photo. On the bottom right is a leaf that has been “punched” by a leaf cutter bee.

I found the first signs of a different pollinator by looking at leaves, not flowers. Some leaves of of our roses had holes in them that looked as if someone had put a hole puncher to them. This is the work of leaf cutter bees (Megachile spp.). These bees do not live in colonies or hives. Every female makes her own nest inside of a hollow stem. She carefully lines it with the leaf circles that are missing from our roses, provisions this nest with pollen, lays an egg and seals the cell. It is thought that the leaf-lining prevents the growth of molds and bacteria that could spoil the food for the bee’s offspring. Our leaf cutter bees are about as large as a honey bee, but they are easily distinguished: while honey bees collect pollen on their legs, leaf cutter bees collect it on their bellies.

Long-horned bees. The upper right photo shows a female with short antennae. The bees with long antennae are males. On the bottom left, a male has just landed on a female. At night, male long-horned bee are asleep on their favorite sunflowers.

Since the first sunflower relatives opened their flowers, I always find Agile Long-horned Bees (Melissodes agilis). They seem to be really partial to flowers of the Aster family, and this is where they hang out for eating, foraging and for sex. In the morning, I could observe how males dive-bombed at females that were sitting on the flowers. A tussle ensued and both bees tumbled into the vegetation. Like the leaf cutter bees, long-horned bees are solitary. Therefore, there are as many males as females around. Males are distinguished by the very long antennae that gave these bees their name. At night, I found male long-horned bees huddled together on a sunflower. Sometimes there were one or two, once I saw as many as five. Long-horned bees build their nest in the soil.

While long horn bees are also about the size of a honey bee, a careful look at the beautiful old garden rose “Apple Blossom” revealed that its flowers were visited by tiny black bees. These are masked bees (Hylaeus sp.), another species of bees that do not live in colonies. They build their nests hollow dead twigs. There is something to be said for a garden that is not perfectly tidy!

Bumble bees on milkweed and lavender.

Many kinds of flowers are visited by the common eastern bumble bee (Bombus impatiens). Bumble bees live in colonies, have a single queen and usually build a nest in the ground, often in an abandoned rodent burrow. I saw quite a few bumble bees and suspect that their nest is somewhere in our garden.

While the masked bees were the tiniest bees I could find, the largest one was an eastern carpenter bee (Xylocopa virginica). Carpenter bees build their nests in holes that they chew into wood. Many home-owners are not happy when they see these big insects hover near their houses. We don’t have to worry: our shed is made of metal and  carpenter bees come to our garden only to forage.

Not all pollinators are bees. On my morning walk, I also saw butterflies. Finally, there are moths, wasps, flies and beetles that visit flowers and play a role in pollination. If we are lucky, we may even see a hummingbird.

Flies are pollinators, too. This one sits on a celery flower.

It is wonderful to know that all of these diverse insects come to our small patch of green in the middle of New York City!

The bee story, a sequel

Our beekeepers had been anxious about the queen-less hive. Another inspection revealed no sign of a fertile queen. Even the previous queen cells were gone. Without eggs or young larvae, the workers could not raise a new queen either. This was not good. Without a queen, the colony cannot exist.

Bee keepers have some tricks in their hat to revive a hive and help the unemployed bees, too. One of them goes like this: take eggs from a thriving hive and put them into the queen-less hive. The bees will then build a new queen cell, carefully move an egg into this cell and feed the larva with royal jelly. Also: move unemployed worker bees to a hive that can use their labor.

Last Sunday, Ray came back to do just that. This time, there were 5 of us helping, as we had to open both hives, check for frames with eggs and keep all bees from getting too upset by keeping the smoker going. Ray first opened the old “white” hive that currently doesn’t have a queen.

Opening the white hive

A frame full of honey

We found that, not surprisingly, these bees had not been lazy. Since there was no brood to take care of, they had made a huge amount of honey. In fact, almost all frames contained only cells that were filled with honey. The box was correspondingly heavy. It needed two people to lift it. A quick search on the internet reveals that bees must visit two million flowers and fly around 50,000 miles to make one pound of honey. This box contained many pounds of honey. Isn’t this totally amazing?

We were glad that our bees were so productive. But we would have been even happier, had we found larvae or eggs instead. These were present in our new “green” hive (along with several frames filled with the sugar water that we had fed them).

Brood cells: In the middle and bottom of the left photo, white larvae are visible inside of open cells. These larvae are still being fed. The other cells contain pupae and have been capped with wax. In the right photo, some larger cells with dome-caps can be seen on the edge of the frame. These have drones inside. Drones are bigger and twice as heavy as worker bees and need more space inside of their cell. A worker bee spends 9 days as larva and another 9 days as pupa. Queens develop a bit faster and drones take a bit longer.

Ray selected a couple of frames with a lot of eggs to move from the green hive to the white hive. We would then move an entire box with honey frames and workers from the white hive to the green hive to give these ladies something else to do.

This swapping of brood and workers has one problem, though: Bees are very loyal to their queen and defend their hive against intruders. To simply mix bees from two hives could result in a massacre, even if the bees come from the same hive initially, like ours. Therefore, we had to make sure to brush off the bees from the frames with eggs before placing them into the white hive. For adding the workers to the green hive, we resorted to a trick. Because hive recognition depends on scent, bees can get used to their new environment as long as this happens slowly. A sheet of newspaper placed between boxes containing two kinds of bees keeps them apart for a while until they are adapted and chew the barrier apart.

Preparing the green hive to receive a box with bees from the white hive. Excess wax has to be scraped off. The Sunday New York Times lies ready to serve as barrier between the boxes.

So this is what Ray did for our bees. He taped a page of the Sunday newspaper over the frames with the green-hive-bees and placed a box with bees and honey from the white hive on top. Then both hives were reassembled. It took the bees a while to calm down and go inside. The new bees on the green hive had an entrance on the top of the hive, as they were, for the time being, kept from using the bottom entrance. After another hour or so, they had reoriented themselves more or less. We now had to hope that the foreign bees were accepted into the green hive. Most of all, we were hoping that the new eggs in the white hive would be raised to become queens.

The first part worked quickly. By the end of the next day, some strange grey-green fuzz covered the ground under the hive. A close inspection revealed that this was the shredded New York Times. Also, all bees seemed to use the bottom entrance to the hive. A couple of days later, we opened the hive again to remove the paper. But the bees had done a very thorough job on their own. Every bit of newspaper in their reach was gone.

It will be a while until we know whether the second aim of this operation also worked. It takes about 3 weeks until a new queen hatches and then, again, she needs to go on her mating flight and come back to the hive. Meanwhile, the workers in the white hive are bringing in more nectar every day. By the way: we got a chance to sample the honey. It tastes very floral and mild.

Update on our bees

As you know, our bees swarmed a little over a week ago. Thanks to East Village bee keeper Ray Sage, we were lucky to catch the swarm that day. A couple of days later, Ray came back with a proper hive. The weather favored us: it was cold and rainy. Ray and Sara gave the swarm some honey from our old hive and a tub full of sugar water. Now, they had not only a dry and cozy home but also enough food to keep the queen happy and start building cells. Who would want to leave under these conditions?

We watched the hives over the week. Our “newbees” finished several portions of the sugar water and also went out to collect nectar and pollen.

Last Sunday, our beekeepers decided to take a look inside the hives. They were curious what progress the swarm bees had made, and they wanted to know whether the old hive had a new queen yet.

Checking the hive

For this planned home-invasion, our bee keepers donned protective gear and started the smoker. It contains wet burlap, paper and dried herbs. This combination produces smoke that does not smell too terrible and calms the bees.

First, the old hive was looked into. It has three levels. The shorter top level holds frames where the bees are supposed to store honey. The two lower taller boxes were full with frames that contained cells with brood: bee larvae at different stages of development and pupae. There were also a number of queen cells. These are larger than regular cells and have the shape a peanut. The larvae inside of these cells are fed a lot of royal jelly every day, a special diet that causes them to develop into queens instead of worker bees.

Our bee keepers did not find eggs in the cells of the old hive. This is a sign that this hive currently does not have an adult queen. For the colony to survive, the workers need to rear a new queen. This queen has to fly away, mate with drones from a different hive and come back alive. Her early life is pretty dangerous until she is back home. Then however, she’ll be very well sheltered and taken care of around the clock and can live up to 4 years. This mating flight is a mysterious event. Drones congregate in certain places and queens somehow find these congregations. How this happens is still unknown, despite centuries of bee keeping and decades of honey bee research.

The bees are carefully brushed off to reveal the cells and their contents (photos: Joe O’Connell).

A look into the new hive showed encouraging activities: there were newly build cells and some of them contained eggs! Here, the queen was doing her royal duty and her workers were busy. No wonder, that they were drinking so much sugar water every day. They have to make a lot of wax to outfit their hive. When a bee is well fed, it is nice and warm in the hive (91 °F to 97 °F) and she senses the need for it, a worker bee secretes wax scales from glands in her abdomen. This wax is then chewed and mixed with pollen and propolis (a resin) to be ready for building the perfect structure that we know as honey comb.

Bees are truly amazing animals. They do so much work, and all of it is well coordinated. Mind you, I am talking about female bees only. The males do nothing. Their only job is to provide the queen bee with millions of sperm for years of laying up to 2000 eggs per day. Knowing that most of them don’t even get to mate, and those that do die in the process, I feel a bit sorry for them.

However, our virgin queens desperately need to mate with drones, otherwise there will be no more worker bees and thus no honey for any of us. Therefore: best of luck to the queens and her mates for a successful wedding flight!

Our fifth Annual Rose Walk begins this weekend

Pink Simplicity looks lovely in the rain

It is mid May and time for our Annual Rose Walk. Hard to believe that we are doing this already for the 5th time! It is definitely a tradition now. The labels are in place, the rose buds are getting big and some are already open. Only the weather does not want to cooperate. It has been raining on and off for several days and the forecast for the weekend is not great either. At least, we don’t have to worry about watering the garden, and this warm rain makes many plants grow happily and quickly. The garden looks very lush. Still, a bit of sunshine would be nice. Of course, the roses will be blooming for a few more weeks and this gloomy weather can’t last. Who wants to go on our Rose Walk may follow the guide below. Enjoy!

 

Guide to the fifth annual Rose Walk:

Enter the gate and look to your left. There is a collection of roses that include Alba White Meidiland, Stanwell Perpetual—an ancient cross between a Burnet rose (Rosa spinosissima) and a Damask rose—and Charles Mallerin.

Don Juan

Now, continue on the path and under the arbor covered with Don Juan. Through the arbor to your right is Phloxy Baby, a 2016 winner of the American Garden Rose Selections. Directly in front of you in the border, The Fairy is planted to the right of the large Rosa laxa. Please take a look at the other roses in this area to your left, which have yet to be identified.

Madame Hardy

Heading up the path, you will see Madame Hardy in the border, a Damask rose that is considered one of the most beautiful white roses ever bred (in 1832 by Alexander Hardy who named it after his wife Félicité). Next are several specimen of the Floribunda rose Pink Simplicity and the lavender colored Paradise that has been moved earlier this year and is still recovering from this shock.

Lavender Dream

Further down the path reveals Lavender Dream. Proudland is the red rose to your left. This area also contains several unidentified roses. Turning the corner, Dream Weaver appears and there is also Pretty Jessica. The next corner contains Chrysler Imperial, one of our oldest roses that was planted in a brick well 39 years ago. It won a Green Thumb contest and a wheelbarrow for the garden back in the ‘80’s.

Citrus Tease

Turning the tight corner, you will come to a large grove of tall red roses, Dr. Huey, frequently used as rootstock for hybrid roses. You will also see Senior Prom and Citrus Tease, and to your right is a rose which we still need to identify.

Following in the border is White Dawn. Look back into the garden to see Orange Honey Sunny Yellow Knockout and Oso Happy Smoothie Pink. There is also Baronne Prévost, an antique hybrid perpetual, and Green Ice, grown from a cutting a few years ago.

Livin’ Easy

Next is Livin’ Easy, and in the border, you will find French Lace, Eglantyne and Morden Blush. In the middle of the garden is one recently planted old garden rose Apple blossom, which was newly grown by the Heritage Rose Foundation and donated to a Green Thumb rose pruning event in Harlem three springs ago.

By now we are sure you are drawn to Zephirine Drouhin. This thornless beauty has been with us a long time. Happy Chappy and Peach Drift, which came to the garden from an AARS giveaway in Union Square years ago, are also here.

Kronprinzessin Viktoria

Please continue down the path, past the gate, and on your way to the patio. You will pass Love and Peace, which was planted in honor of two young neighborhood NYPD auxiliary officers, Nick Pekearo & Eugene Marshalik, who were gunned down on Sullivan street in 2007. Next is Chicago Peace. Follow your nose and be enthralled by the fragrance of Souvenir de la Malmaison, one of our Bourbon roses.

Pat Austin

The following section, next to the patio, is the most concentrated rose garden. Within this area, you will find two other Bourbon roses, Kronprinzessin Viktoria and Captaine Dyel de Graville. There are also a rare Canary Island Damask rose next to Munstead Wood and the hybrid Tea rose Leonie’s Appoline. Near the back fence is Pat Austin.

On the other side of the patio, you will find the Rosa rugosa cultivar Henry Hudson and the hybrid Musk rose The Ballerina. The Ballerina appears again with Dames de Chenonceau and a Pink Meidiland. The very last plot has The Fairy, Tropicana and Dan Poncet.

After leaving the garden, please also take a look at our small North Garden which contains a pink double Rosa rugosa variety and Pink Simplicity. You will also find The Prince behind a red rose, which we still need to identify. Finally, there are the European wild rose Rosa rubifolia and Maigold.

Thank you for coming! We hope this has been enjoyable and informative. We appreciate your ideas and input. If you think you can identify any of our mystery roses, please inform the guardian on duty or send us an e-mail: lgcgardens@gmail.com.
