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.

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.
