Repotting Cactus

Garden Blog - Tue, 01/10/2017 - 9:45am

Repotting a cactus can be intimidating, but a few simple tricks can make the project a lot less painful—and result in beautiful, healthy plants.

When repotting a cactus, there a few essential tools you’ll need:

  • Chopstick or small dowel
  • Cactus soil
  • Container with drainage
  • Gloves
  • Newspaper

Cactus soil is a special blend of potting soil that is formulated for fast drainage. It is usually a blend of peat moss and sand, sometimes including coconut fiber, perlite, or vermiculite. With the increase in popularity of growing cacti and succulents, it has become a garden center staple and can be found at most garden centers and hardware stores.

View video on our YouTube channel

You’ll want to use a container—preferably one that is made from terra cotta—with drainage holes. This allows the water to drain away from the roots rapidly. Cacti are native to dry environments and do not like to have their roots sitting in water. If the drainage hole on your pot is especially large, it can be partially covered with a rock to prevent soil from draining out the bottom when you water. Most cacti are slow growing and should never be planted in a pot that is more than an inch larger in diameter than their previous container. This is to help prevent rot.

Winter is a great time to warm up in the Greenhouses and see our cacti collection.

Repotting your cactus is in many ways very similar to repotting almost any other houseplant.

  1. Begin by filling the new pot ½ to ¾ full with soil.
  2. Remove your plant from its old pot. 
    • Make sure to wear gloves.
    • Roll up a sheet of newspaper to make a strip approximately the same width as a belt. 
    • Wrap your newspaper strip around the plant and use it as a handle to gently lift the plant from the pot.
  3. If the plant is really root bound, gently loosen the soil around it to encourage new growth. (I like to leave some of the soil intact. This provides some weight to help keep the plant anchored. If the soil is poor quality, all of it should be removed.)
  4. Using the newspaper handle, set your plant into its new pot.
  5. Using the chopstick, firm the soil around the base of your plant. Keep adding soil until it reaches the same level as the old soil. (This should be approximately ½-1 inch below the lip of the container.)
  6. Water your plant throughly. 

Your cactus now has much more room to grow, which also means much more soil to stay moist. Make sure to check before watering again—the soil can stay moist for a long time, even if it is a mix made for cacti.

Autumnal Leaves on Loan to Philadelphia

Lenhardt Library Blog Posts - Thu, 01/05/2017 - 9:14am

One of my favorite volumes in the Lenhardt Library’s rare book collection (although I love them all) is Autumnal Leaves by Ellen Robbins, published in 1868. Each of the 18 original watercolor paintings of autumn leaves looks so true-to-life that you want to reach out and pick a leaf off the page.

Sumac illustraion from Autumnal Leaves by Ellen Robbins.

Sumac from Autumnal Leaves by Ellen Robbins

This volume, specifically, the sumac watercolor, will be on display at the Philadelphia Museum of Art, in the American Watercolor in the Age of Homer and Sargent exhibition which runs March 1 to May 14, 2017. I’m delighted that an East Coast audience will have the opportunity to share this treasure.

Although we’ll miss the book while it’s away, through the Lenhardt Library’s digitization program, each page of the book is viewable in the Illinois Digital Archives repository.

You’ll find the sumac shown here on page 4 of the content list. View the full collection of prints here: http://www.idaillinois.org/cdm/compoundobject/collection/ncbglib01/id/3364/rec/2

Additionally, the sumac will be published in the American Watercolor in the Age of Homer and Sargent exhibition catalog.

A unique, one-of-a-kind book, this is the only copy listed with holdings in a library.

Bound with gold tooling and gilt edges, the volume is quite brittle and fragile. It has just been conserved by a professional book conservator to prepare it for exhibition.

Add green to winter drab—plant evergreen perennials

Garden Blog - Tue, 01/03/2017 - 3:02pm

Most perennials are deciduous. They go dormant when their above-ground parts die in the fall and then they rely on the energy and nutrient reserves stored in underground roots during the winter. But without a pretty blanket of snow all season, a garden can look drab and dead. Fortunately, there are some perennials with attractive and durable evergreen foliage that last the winter months, even in Chicago.

Why do they stay green so long? Well, evergreen leaves contain lignin, the same polymer in the cell walls of woody plants, throughout the veins and surrounding tissues. This makes them waxy, durable, and less prone to wilt or tear. These leaves are also less likely to get diseases or be browsed by critters. But the main reason for a perennial to have evergreen leaves is to provide a place to store energy and nutrients while they are dormant.

Evergreen perennials are quite trouble free but having modified leaves comes with a price. They are vulnerable to winter burn, a situation where the leaves become dehydrated, leading to injury or death. This can occur in late February or March, when sunlight is directly hitting the plant and the soil is still frozen. The sunlight heats up the leaves and causes them to transpire (lose water), yet the roots remain frozen and unable to replace what was lost. Fortunately, snow cover protects evergreen perennials by shading them and insulating the ground. Also, planting them on the north or east side of a structure will provide ample shade in late winter because the sun is lower.

The energy and nutrient reserves in evergreen leaves are utilized by new growth in spring. This is why most evergreen perennials do not shed their original leaves until the fresh leaves are complete. Older leaves can look shabby by spring, especially after some winter burn, but do resist the urge to cut them off in your garden until this transfer of reserves is complete. Prematurely removing evergreen leaves can weaken the plant and cause them to flower less.

Here are some of the best perennials with evergreen foliage for the Chicago area:

Bergenia cordifolia 'Bressingham White'

Summer: Bergenia cordifolia ‘Bressingham White’

Bergenia cordifolia 'Winter Glut'

Winter: Bergenia cordifolia ‘Winter Glut’

Bergenia, pigsqueak
(Bergenia cordifolia)

Bergenias have 1-foot-tall, leathery, paddle-shaped leaves that turn a mahogany color in the fall and winter. In early spring, clusters of pink flowers are held on thick stems. Blooms are sometimes seen during cooler weather in autumn. Plant bergenias in a partly sunny spot that is moist, but not wet. The common name, pigsqueak, comes from the sound that is made when rubbing a leaf between your fingers.

Helleborus x hybridus 'Blue Metallic Lady'

SPRING: Helleborus × hybridus ‘Blue Metallic Lady’

Helleborus x hybridus 'Solace'

Winter: Helleborus × hybridus ‘Solace’

Hellebore, Lenten rose
(Helleborus × hybridus)

Before the snow has even melted, you will find hellebores in flower. The common name, lenten rose, refers to the ability of this plant to bloom at the beginning of Lent. Green, white, and maroon are the most common flower colors found, and some have attractive spots on the inside. The evergreen foliage is less than 2 feet tall, coarse and leathery, and combines well with ferns and other woodland plants. Rich soil and shaded conditions suit it best and under such situations, self-seeding may occur.

Heuchera 'Carnival Rose Granita'

Heuchera ‘Carnival Rose Granita’

Coral bells
(Heuchera spp. and cvs.)

Coral bells are very popular today, and breeding efforts have led to an overwhelming amount of options to choose from. The maple-like leaves can range from burgundy to black, caramel to red, and chartreuse to silver. Flowers have gotten showier and last much longer too. If afternoon sun is avoided, and the soil is well-drained, they are tough perennials that remain visible all winter long.

Liriope spicata

Liriope spicata is green all summer—and winter—long.

Creeping lilyturf
(Liriope spicata)

Creeping lilyturf is a tough, drought-tolerant groundcover for sun or shade. It spreads by rhizomes and makes a nice alternative to grass, provided you don’t plan to tread on it very much. It also competes well with tree roots. In autumn, the plants produce interesting spikes of violet flowers (sparingly) that lead to black, shiny fruits that look like beads. Variegated cultivars are available too.

Japanese pachysandra
(Pachysandra terminalis)

Japanese pachysandra is an extremely common groundcover for shaded landscapes. It spreads quickly and, once established, remains weed and maintenance free. The glossy dark green foliage is attractive year round, and in spring it boasts fragrant, ivory white flowers. There is also a pachysandra that is native to the Appalachians.  It is called Pachysandra procumbens and it too forms an evergreen groundcover, though much more slowly over time.

Pachysandra terminalis

Spring: Pachysandra terminalis

Barren strawberry
(Waldsteinia ternata)

Barren strawberry is a superb, 2-inch-tall, groundcover for sun or partial shade. The plants are stoloniferous, like strawberries, and spread quickly into a weed-proof mat in well-drained soil. In mid-spring, barren strawberry is loaded with sunny yellow flowers that have five petals each. Hailing from Europe, Japan, and China but a native species, Waldstenia fragaria, has very little difference in habit or growing conditions.

Pachysandra terminalis

Winter: Pachysandra terminalis

Polystichum acrostichoides

Polystichum acrostichoides emerges under melting snow

Christmas fern
(Polystichum acrostichoides)

Native to Chicago and the eastern United States, Christmas fern is one of the few truly evergreen ferns that are effortless to grow. All it needs is some shade and a well-drained spot, and in a few years, you will have a sizable 2-foot-tall plant, forming a 2-foot-wide clump. In spring, cute fuzzy fiddleheads emerge out of the dark former fronds. You can start your own colony of Christmas ferns by digging up mature plants and dividing them into additional ones.

Barren strawberry
(Waldsteinia ternata)

Barren strawberry is a superb, 2-inch-tall, groundcover for sun or partial shade. The plants are stoloniferous, like strawberries, and spread quickly into a weed-proof mat in well-drained soil. In mid-spring, barren strawberry is loaded with sunny yellow flowers that have five petals each. Waldsteinia ternata hails from Europe, Japan, and China. The common name, barren strawberry, is shared with another species, W. fragariodes. The latter is native to the United States; however, nurseries offer it much less frequently than W. ternata.

Waldsteinia ternata

Winter: Waldsteinia ternata

Waldsteinia ternata

Spring: Waldsteinia ternata

Plant Collecting in the Republic of Georgia

Garden Blog - Mon, 12/19/2016 - 10:12am

This past summer, the Chicago Botanic Garden joined an intrepid team of plant collectors from four other American institutions on an expedition to the Republic of Georgia.

Our focus: to collect seeds to diversify the genetic diversity of ex-situ plant collections; to bring back and evaluate species for their ornamental potential; and to provide a hedge against natural and man-made disasters—all while building upon institutional collaborations developed during previous expeditions.

Just east of the Black Sea is the Republic of Georgia. Map courtesy worldatlas.

The Republic of Georgia was chosen because it is the only biodiversity hotspot that is situated within the temperate climatic zones.

Over millennia, the high peaks of the Greater Caucasus Mountains to the north, Lesser Caucasus Mountains to the south, and their inter-connecting mountain ranges situated between the Black Sea to the west and Caspian Sea to the east have provided a refuge for species that have gone extinct elsewhere due to glaciation and other climate extremes.

Tucked into hundreds of microclimates created by this varied topography, many of these endemic species (found nowhere else on earth) are perfectly hardy in American, Russian, and European gardens much farther north. 

Coordinating the trip on the Georgian side were our colleagues from the Institute of Botany, Tbilisi and Bakuriani Alpine Botanical Garden. They provided invaluable logistical support through the use of two of the foremost botanists in the region, drivers, vehicles, and places to stay.

In a little more than two weeks in the field, the group traveled more than 1,100 miles from the high—and barely accessible—Greater Caucasus Mountains of the Tusheti region in northeastern Georgia, through the central valleys, to Lake Tabatskuri in the Lesser Caucasus Mountains in the south, between the Tetrobi Reserve and Bakuriani Alpine Botanical Garden.

The geographic location of Georgia (Russia to the north, Central Asia to the east, Persia to the south and Asia Minor, the Middle East, and Europe to the west) has made this region a favorite transit point for merchants. Tucked into remote mountain valleys are small communities created from the descendants of Greeks, Germans, Hebrews, Persians, Armenians, Turks, Russians, Circassians, Huns, Mongols, and more, with remnants of each people’s own unique culinary, religious and linguistic traditions.

It was also, unfortunately, a thoroughfare for invading armies. Ancient fortifications, places of worship, homes—all show evidence of destruction and rebuilding.

The collections wrapped up with a foray into western Georgia (ancient Colchis in Greek mythology) in and around Kutaisi, the legislative capital and its third largest city. A brief visit to the Kutaisi Botanical Garden was in order here, before we left the region. A highlight: a small shrine built inside a living 450-year-old oak. 

In all, 205 different seed lots and herbarium vouchers—representing 169 different species of trees, shrubs, perennials, and bulbs—were collected, including six of seven species of Quercus (oaks) in support of the IUCN Redlist of all of the Quercus in the world.

While we each came away with a fantastic collection of seed to propagate, this trip was about much more than collecting plants. Our journey’s end featured a meeting with representatives of institutions from America, Armenia, Azerbaijan, and Georgia all focused on expanding collaboration to match areas of expertise with areas of need—not only in the area of collections, but also horticulture, conservation science, education, and fundraising/collaborative grants.

Identifying Trees in Winter

Garden Blog - Mon, 12/05/2016 - 3:08pm

So you think you’re an ace tree identifier. Those big scalloped leaves are from oak trees, the three-fingered hand shapes are maple leaves, those little oval leaves marching in a double line along a stem are from an ash—boo yah!

OK, now do it without any leaves.

And yes, you can…with a little help from Jim Jabcon, assistant ecologist for natural areas. The other day Jabcon, walked me through the McDonald Woods and began my education.

Jim Jabcon is giving a class on Identifying Trees and Shrubs in Winter on December 10. Sign up today!

First, he corrected my misinformation. I always thought the trick was looking at the tree’s habit—its size and shape. But no—especially not in a natural woodland like this. A tree’s habit depends on where it is growing—how crowded it is by other trees and what it has to do to catch some sunlight.

“Any tree will change its habit depending on what is given to it,” he said as we walked into the woods. “You can probably get 100 trees in a row, but it’s like a fingerprint. They all have different spaces, different light; they’re all going to be different.”

Still, there are some distinctive shapes. Does the tree have thick branches, even at its top with a fearsome, gnarly look worthy of a horror movie? Jabcon nodded at a towering behemoth that could have played a role in The Exorcist: it was an oak.

But let’s start with a major clue: bark.

Jabcon cast a practiced eye—an artist’s eye, in fact, for his degree is in fine art—over the trees. He pointed out a tall tree whose trunk was covered in thick, rough bark.

That bark is the giveaway. The tree was an oak; the tough bark is its secret to surviving fires.

Nearby, another tree boasted thick bark with a rugged geometry, forming blocky rectangles running vertically up the tree in a kind of forest version of cubism.

“This is your black walnut,” Jabcon said. “It’s got a really good knobby bark.”

It also had another tree, a small sapling, growing in a crook about 5 feet up. Jabcon pulled it out and showed how its slender reddish branches were covered with a white chalky material that scraped off easily. “This is your box elder, in the maple family,” he said.

And further along the trail was a tree that won my heart because it looked like another part of a human body.

Its smooth, gray trunk was wrapped in bark with the sinewy look of muscle.

That was because the tree was a muscle wood—the common name for an American hornbeam, bestowed because of the signature appearance of its bark.

Walking on, we stopped at another tree with its own distinctive bark, which looks like big hunks of bark pasted onto the trunk and separated by deep grooves. That “warty” bark, as Jabcon put it, identified it as hackberry. (Celtis occidentalis)

Blogger Kathy J. gives you a Tree 101 on hackberry in her post This Bark is Rough.

Still, bark isn’t the only clue. Jabcon pulled a slender branch close and examined the leaf buds running along its length.

They were in neat pairs, each bud opposite another. “Very few trees have opposite leaf buds,” he said. “Ashes. Maples. So if you’ve got opposite buds you can narrow it down.”

To make the final ID, he examined the terminal bud—the bud at the very end of the branch. It consisted of a cluster of three tiny points, making the branch look almost like a miniature deer hoof. That distinctive shape settled it: this was a white ash.

And so it went as we wandered through the woodland.

We looked at leaf buds, like the sulphur yellow leaf ones (“I love how cool they are,” Jabcon said) on a bitter nut, one of his favorite trees.

We looked at terminal buds, like the super-long ones that look like a goose’s bill and mark it as a nannyberry, a kind of viburnum.

We looked at bark, like the one hanging in huge strips off a tree. It was a shagbark hickory. This tree’s bark has peeled off in such big pieces that bats have hibernated beneath them.

And if all else fails, there is another clue still there in winter, though soon it could be hidden under snow.

“It’s OK to cheat and look at leaves on the ground,” Jabcon said cheerfully, picking up a few oak leaves to prove the point. “They’re still there.”
