I was presenting at an outdoor gardening event recently when a woman walked by wearing a tee shirt that said, “No Pinching!” Maybe she had young kids, or was a kindergarten teacher. Clearly she was not an experienced gardener. Pinching plants is good, and now is the time to do it.
Let’s start with fruit trees. Many apple trees are loaded with small fruit now. Often there are 5 or more fruits together, especially at the tips of branches. If you pick off all but one or two fruits now, they will grow to a nice size. If you leave all the fruit on the tree, each fruit will be smaller. Not only that, you can often see what fruit is already damaged by insects and disease; it is smaller, and discolored. Removing that fruit will help the fruit you leave to be healthier. And eventually, you have to pick all the fruit anyway. It’s easier to do it now than in the fall. Leave the biggest, best looking fruit.
To thin fruit now, hold the cluster of small fruits in one hand, and pinch them off with the other. Holding the cluster helps to avoid breaking off the fruit spur and all the fruit on it. You can use pruning shears, but it is faster just to pinch (or pull) off the fruit. Don’t throw the fruit on the ground; it may be diseased or harbor insect pests, so you want to get rid of it. Come with plastic buckets and place them strategically around the tree as you work.
Work your way up the branch. Leave an apple or two every 8 inches. Michael Phillips, the author of two excellent books on growing organic apples, explains The Apple Grower: A Guide for in the Organic Orchardist (Chelsea Green Publishing, $40) that it is good to take all apples on alternating fruit spurs. This promotes a good harvest every year instead of a big harvest every other year, which is common on some varieties of trees. And remember, as you lament pulling off potential pies, that there is a limit to how many apples most of us can use.
I recently pinched off a bucket of blossoms from that terrible invasive weed known as goutweed or Bishops’s weed (Aegopodium podagraria). I have come to accept that I will never rid myself of this noxious pest, but I do believe I can limit its spread. It spreads quickly by root, which I limit with a lawnmower and some pulling. Seeds? From a reading of the literature, that they do not appear to be a primary means of dispersal. Still, in 15 minutes I can rid myself of the seeds, so I do. No point in taking chances.
When picking the goutweed flower heads, I ended up using my pruners, because with each flower, there is usually a lower, secondary flower cluster that is still developing under the shade of the leaves. I want to get both, so I reach down and snip off the stem lower down. Instead of tossing the flowers in the compost, I put them in the household trash that will go to the incinerator. A fitting demise for a devilish plant.
Annual flowers are coming in to bloom now, and pinching off spent flowers is important. I have some nice purple verbena growing in a window box by the front door. I often pause for a few moments and look at it to see if there are spent flowers. There always are, and I pinch them off. This stimulates the plant to set new buds. After all, it wants to make babies – and if an herbivore or a tidy gardener has removed its seeds, it needs to make more, starting with new flowers.
Not all annuals need to have their flowers pinched off. Some are called “self-cleaning”. They drop their flowers once they have finished blooming. Impatiens, begonias, and Euphorbias like ‘Diamond Frost’ are self-cleaning. Those that do need deadheading include annual bachelor buttons, gazanias, geraniums, marigolds, osteospurmums, pansies, pincushion flowers, salvias, snapdragons, sunflowers, verbenas and zinnias.
Another June task is to pinch or cut back tall summer- of fall-blooming perennials that you wish would stay shorter or bloom later. But you must do this now, or soon. It is fine to cut back these perennials when they are starting to form buds. The stems that you cut back – I recommend cutting off 4 to 6 inches – will have smaller flowers and often instead of 1 flower per stem, may have multiple blossoms.
I have already cut back my Culver’s root (Veronicastrum virginicum) and some of my bee balm (Monarda didyma). Both respond well to it. They bloom at a shorter height. My Culver’s root, if left alone, will often flop over –it can reach 4 to 5 feet in height. I cut back stems in a ring around the perimeter of the big clump, leaving just a few at full height in the middle. The lower stems help support the taller ones, and they bloom at different times.
There is a wonderful book by Tracy DiSabato-Aust, The Well-Tended Perennial Garden (Timber Press, $34.95) that nicely explains cutting back, and lists those perennials that respond well to it – and those that do not. She recommends cutting back asters, purple cone flower, Joe Pye weed, helenium, phlox, rudbekias and more.
So go ahead and pinch something. You’ll see it’s good –despite what you may have learned in kindergarten.

Most mornings in winter I start my day with a bowl of oatmeal. That can get pretty dull, so I liven it up with a variety of fruits, most of which I grew myself and preserved either dried or frozen. Add some cinnamon or cardamom and a few nuts, and bland becomes bodacious. In my freezer I have blueberries, elderberries, blackberries, plums, apples, raspberries and a few peaches that I got by trading some apples with a friend. So if you’re bored with breakfast, do some studying now about the various fruits you might grow, and plant them this summer.
Much of what I know about gardening comes from practical experience: ask a good gardener, for example, what kind of peach tree she grows, plant one, and see how it does. Try again if the first one dies. But I also depend on reading good books on gardening, and now, while there is still snow on the ground, I spend considerable time reading.
I have two books on fruit growing that I like a lot. The first, written in 1992 by Lewis Hill of Greensboro, Vermont, is a classic: Fruits and Berries for the Home Garden. Lewis was a friend of mine (he passed away in 2008) and a Vermonter to the core: quick –witted, hardworking, and curious. He grew up on a dairy farm and only had a high school education, but with his wife Nancy, he wrote 16 excellent gardening books. His book on fruits and berries is full of good information but also entertaining. It has recently been updated, I just learned, by University of Vermont professor Len Perry as The Fruit Grower’s Bible.
The other fruit book I like is Lee Reich’s Grow Fruit Naturally: A Hands-On Guide to Luscious, Homegrown Fruit, which came out in 2012 and is full of color illustrations and good drawings. Like Hill, Lee Reich is opinionated, thorough, and has many years of experience. Lee has a PhD in horticulture and lives in upstate New York.
Reich’s book introduced me to two fruits hardy for Zone 5 (possibly even Zone 4) that I have never grown or tasted: the medlar and the shipova. The medlar is a small tree that is self-fruitful, meaning that one tree is all that is needed for pollination. According to Reich’s book, the medlar blossoms open late enough to almost never be bothered by spring frosts. The fruit keeps well and is very tasty. So why have I never heard of one? Reich writes, “The flesh, when ready for eating, is brown and mushy and lacking visual appeal.” It also needs “bletting” or ripening on a shelf in a cool room, the cooler the better.
The Shipova is actually a hybrid made from two different species, a type of mountain ash (Sorbus aria) and the European pear. Reich lists it as a Zone 4 plant, so it is hardier than the medlar and should survive my New Hampshire winters easily. It produces pear-like fruit on a tree that can grow to 20 feet, or if grafted on a suitable rootstock, only 8 feet tall. He says that are ready for harvest in mid-summer. Unlike the medlar, the fruit does not keep well – but it is attractive to the eye and tasty, too. I called Lee, and he said the fruit tastes similar to a pear.
Reich made it clear that fruits like the medlar and shipova are not often sold at our local nurseries, so I went on-line to see where they are available. Raintree Nursery in Morton, Washington (http://www.raintreenursery.com) had both for sale. In the back of Reich’s book there is a list of nurseries that sell fruit trees, including St Lawrence Nurseries in Potsdam, NY which has lots of cold hardy trees that can be ordered bare root until April 10.
Lee Reich’s book is just chockfull of tidbits that are useful. He explains, for example, labels on pesticides: ‘caution’ means the material is slightly toxic or relatively nontoxic. ‘Warning’ means moderate toxicity, and material marked ‘danger’ might kill you – even in small quantities. Lee is a proponent of organic techniques, but points out that even pesticides approved for organic growers can have severe side effects. He notes that nicotine sulfate is an extract of tobacco that is “organic” but has a danger label. It’s important to pay attention to warning labels whether you are using organic pesticides or not.
I also like the fact that Reich’s Grow Fruit Naturally has specific cultivars named for the fruits it describes, and offers useful tips such as whether a variety is self-fruitful or not. There is a nice section on pruning and another on proper planting techniques.
Call me a skeptic, but I like to buy trees from local nurseries as it means that the owners probably have grown what they are selling. Still … I love to experiment with new plants, and usually try something new every year. This just might be the year for a shipova or a medlar. I wonder how they are on breakfast cereal?

This has been a great year for flowering trees and shrubs. My Merrill magnolia had many hundreds of white blossoms in late April.
The crabapples everywhere put on a spectacular display this year. My fothergilla (a shrub with great fall leaf color) is in bloom now with its tidy white bottle-brush flowers. My ‘Olga Mezitt’ rhododendron (one of the parents of the popular PJM rhodie) is looking great and my wild azaleas are getting ready to bloom. And now the lilacs are blooming for me and I am overwhelmed with the large purple, blue, white and pink panicles (clusters of flowers). Spring has definitely sprung.
All these blooms this year will certainly encourage many gardeners to buy trees and shrubs and plant them. That’s a fine idea, but if you plant now, please remember that you must keep watering them all summer if we don’t get an inch or more of rain per week. When August comes around it will be easy to have your new tree dehydrate if you get lazy or forgetful.
New trees and shrubs need a year or more to grow roots sufficient for their needs if we get hot, dry weather. So if you are forgetful or will be doing lots of traveling, you might want to hold off on planting a new tree until fall, which is also a good time for planting. Fall is cooler and more likely to be rainy.
I like to buy flowering trees and shrubs when they’re in bloom. That allows me to see the color and check out the fragrance. But there is more than just the flowers to consider when selecting a good crabapple or magnolia. Let’s start with size and price. Bigger
is not necessarily better. If you are on life support and don’t expect to be around in 5 years, sure, buy the biggest tree you can afford. But be aware that a bigger tree is not only more expensive – it is also harder to plant and takes more water and care. A bigger tree may have a smaller proportion of its root system intact after being dug up and put in a pot than a small tree. I like to buy smaller specimens and then train them to be a nice shape. That’s harder to do on a larger tree.
I recently visited a nice new nursery run by Henderson’s Tree Service on Rte 14 in Hartford, Vermont. There I chatted with my friend Sylvia Provost who is co-owner of the business. I asked Sylvia what she would look for if purchasing a crabapple for herself. Without a moment’s hesitation she responded. “Structure,” she said.
What Sylvia was talking about is the shape of the tree and the placement of the branches. Fruit trees produce best on branches that leave the trunk at a right angle or are aiming just slightly upward. Branches that shoot straight up are not usually good fruit and blossom producers.
And although Sylvia noted that you can train a tree to be the shape you want, it is easier to start with something that is closer to your ideal before you start training. So, for example, Sylvia said that if you have a swimming pool some distance from your patio, you should choose a tree that has an open format, one that you can see through – and see what is happening at the pool. Conversely, if you have nosy neighbors and want to screen their view of your patio, you might select a tree that has a full, dense arrangement of branches.
Generally, pruning a tree should begin in the second year of its life at your home. I often see apple and crabapple trees that have very low branches. I like to prune off those low branches to make it easy to mow around, and to have a nicer look. And if two branches are both striving to be the “leader” or the dominant, tallest stem, I remove one. And although most books say you should prune fruit trees in March or April, you can safely make a few judicious cuts now to train your tree.
You may train branches to grow at different angles by weighing them down – if you do so soon. This is an activity for spring, starting before the new layer of cambium growth has occurred. You can drive a stake into the ground and tie a branch to it for the next 2 months. A branch the diameter of a finger can weighed down by hanging a plastic pop bottle on it, then filling it with water until it bends to the correct angle.
Chris Wilson of the EC Brown Nursery in Thetford, Vermont suggested that when buying a tree, look at leaf color – leaves should be green, not tinged with yellow. He also suggested making sure the tree has branches on all sides, and that the bark has not been damaged.
So if you’ve delighted in the flowers on trees in your neighborhood this year, go get one or more. Study several specimens to find the best one. And just remember to water all summer long!
