I recommend an essay by Mary Seton Corboy about why we garden. I love how she describes the dignity and connection achieved by working the soil. See what you think!

From WHYY’s web site: July 16, 2010 – Mary Seton Corboy founded the Greensgrow Farm in 1998. She and her team of gardeners have become a national model of perseverance and commitment to urban farming. Corboy transformed a superfund site into a thriving garden that is still in full swing. In her essay she explores her belief in the power of physical labor.

During the month of July, water, or the lack of it, is a constant theme for people who live in Delaware. Below are a series of excerpts from family letters about how to keep cool during this long hot month! H.F. du Pont created the Glade Garden in the early 1930s. Now eighty years old, it is still one of the most beautiful places n Delaware to  cool off on a steamy afternoon.

The Glade Garden at Winterthur

July 13, 1849, Evelina du Pont Bidermann, the first owner of Winterthur, wrote  to her son and daughter in law in Paris: We have a delightful Spring near the garden where the water continually wells from the ground and which is so cold as if it had been put in the ice. I often visit it and we intend this autumn improving the way to it that Gabrielle and Marguerite may enjoy going there as it is the rendezvous of various birds & tortoises who go to drink. I often fancy our dear children’s little footprints in the lawn and in the alleys and long to transplant these little living flowers to our shores or rather our woods of Winterthur where I hope they will share the happiness that they will give us.

July 22, 1941 H.F. du Pont, the last private owner wrote to W.A. Brooks: I am here [Winterthur] from Southampton for my every other week visit and am thankful that is has finally got dry enough so that we can thresh our wheat. A few more wet days and it would have sprouted in the fields and you know what that means to a farmer.

July 1942 to Albert Ely Ives: We have been here all summer and it has been very pleasant. Everybody else is staying home also.

July 18, 1845 Evelina Bidermann to her son in Paris: I wish I could send you in this letter some of our flowers trees and grass of our garden and also the bright blue sky without a cloud we have today , the moaning of a refreshing breeze throught the foliage the cooing of doves the livelier chirping of little birds and the many rural sounds which surround me as  I write by the open window.

July 18, 1941 to Mrs. Chamberlain Chanler, HF271: After a long draught here, it is raining its head off and everything is rotting away. The trials of a gardener are manifest!

July 21 1902, Pauline du Pont to her sister Anna:  We have had some delicious water-melons and pretty good peaches and lots of white raspberries.

July 23, 1943 to Bessie Andrews: Everyone is gardening furiously, freezing and putting up all kinds of vegetables for next winter. With the help of several boys we manage to keep the place looking quite nicely. The poor despised farmer has at last come into his own! We have beef cattle, sheep etc. and o our own slaughtering, so we don’t bother with those terrible rationing coupons.

July 29, 1854: Evelina du Pont Bidermann to her son and daughter in law in Paris about her grandchildren: I wish they were here to see a new flower I have, a Japan lily It is in bloom now and very beautiful. My night blooming cereus is going to have four large blossoms.

By Frank Quinnette, Winterthur Turf Horticulturist

Whether you believe in global warming or cyclic temperature fluctuations, all I know is that it’s been hot and it has finally rained!

After days of the temperature and humidity readings looking like scores from blowout basketball games (104/48 %, 105/52 %, etc) the rain has come to rejuvenate the grass.

The grass going dormant and brown in hot dry conditions is not unusual. The truth is, it is normal for cool season turf grasses to shut down when it’s hot and dry to prevent fatal plant desiccation. The rain today will help wake the grass from its sudden slumber. Watering helps tremendously to cool things down for turf growth to continue in harsh conditions, but it must be done properly throughout the year. The same with mowing. And using drought tolerant turf grass varieties will also help to reduce the effects heat stress from shutting down a lawn.

I’ve come around to the fact that we aren’t set up to water all the turf I want watered here at Winterthur. That’s cool. I’m all about priority. So I try to use good cultural practices all year. Of course there are those years… (2010). Who knew that after 50in. and change worth of snow we would be looking at dry ground this summer? Humidity so low and temperatures so high only scorpions, Gila monsters, and southern Californians could survive.

Watering properly and timely is the key to good turf growth year round.

Water when the grass starts looking “kinda bluish” to quote a friend in the business. You’ve seen it like that. Mostly after it has been cut. It gets that blue-green color to it. If you walk out on it when it’s like that you’ll notice that you leave foot prints that may not go away as quickly as normal. At that point you need about 2 inches of water on it. To measure how much water your sprinklers are putting down, mark the inside if a can or plastic cup with 1 inch increments and place it at the end of the sprinklers reach. Come back after 30 minutes, check the measurement and double it. That will tell you how many inches per hour of water you are putting down on the turf. Make sure you get complete coverage from your sprinklers or you will see the difference later, as shown in the photograph below.

Mowing should be done at the highest setting on push mowers and no lower then 3 inches on riders. The higher the better. A change of half an inch higher can make the difference between a green lawn and toast. You need a sharp blade. Clean, even cuts heal faster and prevent water from escaping from the grass plants. Mow when it is coolest during the day. Evening is best for me at home mainly because my neighbors formed a lynch mob the last time I tried to cut my grass before 9am. Here at Winterthur, I mow when I can see the grass and go until things get a bit too warm. Almost never past 11am when temps are expected to be above 90 degrees. That gives the grass time to recover and heal before the hottest part of the day. If you do mow in the morning, water right after you are done to reduce stress.

Drought tolerant grasses such as tall fescue are thick bladed, clump type grasses that take heat like a champ. Properly seeded in the spring or fall these grasses are great for areas where watering times are few and far between. We use mostly tall fescue mixes. Check with your local garden center to help with best seed choice for your lawn.

If your grass has gone dormant because you’ve done none of the above, then good for you! That’s where we’re at here at Winterthur. You don’t have to mow. You don’t have to water. I wouldn’t get too close to it with an open flame but you can claim it on your taxes as energy efficient savings (joke…I’m not an accountant or a tax cheat). But it is good for the environment in a way. The use of that method at Winterthur allows me some time to become reacquainted with my team mates and some muscles I haven’t used in a while. I also get to write this.

Summer Interns

Winterthur Summer Interns: Mark Wolanski, Susan Fallon, Gabriela Weber, Kelly Cunningham, Christine Hare, Sam Bond

A moment was finally found in between watering new plantings to introduce you to some new faces in the garden. Our summer interns began working with us in late May and will continue through mid-August as their school schedule allows.  They work alongside staff in the department to learn plant I.D., design, and horticultural skills as they pertain to the field of public horticulture.  Not only does this give the students some hands on experience but it provides the Winterthur Garden Staff with much needed help during the busy growing season. 

Garden\Estate Interns
Susan Fallon is from Philadelphia, PA. Susan is a student at Temple University and will be graduating in winter 2011 with a degree in Horticulture. Susan first had a successful career in Medical Laboratory Technology but reached a point of wanting more from her occupation so she went back to school for a career change to horticulture. Susan first visited us during one of our GardenFair weekends and fell in love with Winterthur.

Kelly Cunningham is from Milwaukee, WI. She will be receiving her Associate’s Degree in Landscape Horticulture/Design in December, 2010 and then plans to pursue a Bachelor’s Degree in Horticulture. Kelly hopes to gain a greater sense of what direction she would like to take her career while she is interning at Winterthur.

Gabriela Weber is from Saint Louis, MO. She attends Southeast Missouri State University and will graduate with a Bachelor’s Degree in Horticulture in May 2012 with further plans to obtain a Master’s Degree in Landscape Architecture. Gabriela is very interested the design principles used by H. F. du Pont in the Winterthur garden and feels that it is important to learn from the past experiences of other people as well as her own past experiences to prepare for a future in horticulture.

Christine Hare is from Newark, DE. She is a senior at the University of Delaware and will graduate with a Bachelor of Science in Landscape Horticulture in winter 2010. Christine feels that this opportunity with Winterthur will greatly enhance her understanding of all aspects of horticulture and prepare her for a successful career in the industry.

Arborist Intern
Sam Bond is from Kempton, PA. He is currently at Penn State Mount Alto for Forest Technology where he will receive an Associate’s Degree. Sam’s special interest is in pruning and caring of trees and shrubs.

Natural Lands Intern
Mark Wolanski is from Wilmington, DE. Mark graduated in winter 2010 from The University of Delaware with a Bachelor of Arts in Geography and will pursue a Master’s Degree in Environmental Science from Wesley College in Dover, DE. Mark has been working in the Garden since March when he rotated between garden areas as a Garden/Estate Intern (Mark’s first task was trekking through the snow to help pick up debris from the last blizzard. Ahh…snow). Mark summer rotation is in the natural areas on the Winterthur property which will help prepare him for his Master’s program in September.

Hats off to Debbie Harper for sharing her observations of sharing the Winterthur Garden with her teen-aged daughter on Wednesday, July 7th.

My daughter and I walked in the garden yesterday, and it really was lovely.  Of course it was just us and our shadows out walking – and the chipmunks, squirrels, birds, and butterflies, all of whom were completely undaunted – but we stayed in the shade, and found we were just fine — there was even a breeze. 

We cooled our ankles in the Misting Mushrooms and indulged in a bag of Jelly Bellies in the Acorn Tearoom – there are worse ways to spend a lunch hour!  In this intense heat, anything in bloom – the white hydrangeas, and the purple hostas, and the Russian sage – was an especially welcome sight, really delightful to see – I wish more folks would try it – hopefully the blog can inspire them!

(Thank you to our guest author!)

Jeni Jackson offers her experience in the Winterthur Garden:

Even in the sweltering heat, I managed to find a nice, shady path to walk yesterday on my way to my car and enjoyed the Hostas’ impressive blooms.  I’m amazed at how full the stalks of flowers were, even with so little rain.

(Thanks, Jen!)

Summer in the Garden

Want an escape from this nasty heat wave? Take a leisurely walk in the shade of Winterthur’s grand trees. Feel the temperature drop as you walk from the bright sunshine into the cover of deep, refreshing green.  Breathe in the freshly filtered air of the Winterthur Garden.

What’s in bloom this week? The July 7th bloom report lists Vitex (a blue shrub seen at the entrance drive and on the road to the parking lot), Butterfly bush (Buddleia davidii), Rose-of-Sharon, Sweet Joe-Pye Weed, Dwarf Plumbago, Russion Sage (Perovskia atriplicifolia), Oakleaf Hydrangea, Crape-myrtle (Lagerstroemia), Astilbe, Black-eyed Susan, Ligularia, Cosmos and Verbena bonariensis.

The main attraction for me, though, is always the stately, verdant trees…and I’ll admit, the wonderful stone walls that are home to a colony of chipmunks.

Enjoy the Winterthur Garden this summer!
