Start thinking now about divisions, surplus, or highlight plants you can share. Pot up perennials, annuals, and woody plants as early as you can in the spring. See ‘The Rules’ about what to bring and not to bring.
No plants to exchange? No problem! You can buy plants at the sale following the exchange. Hundreds of plants remain after the exchange for purchase by members. Most are priced at just one dollar.

Helpful Tips
Plant Propagation
Pots
Labeling
Resources
Plant Propagation
- Please divide and transplant a few weeks before the Exchange & Sale. Perennials can generally be divided starting early in April, but need time to recover before the event.
- To divide perennials, lift the plant from the ground with a shovel or fork. Use a sharp spade to cut the clump into pieces. Transplant each new piece into a disposable pot, filling it with potting soil.
- Store the potted divisions outside and keep up with watering, since container plants dry out more quickly than those in the ground.
- If you plant seeds indoors and plan to bring homegrown vegetables, herbs or flowers to the Exchange, be sure to harden them off by exposing them to progressively longer hours outside before you bring them to the Exchange.
Below are some additional links to tips on plant propagating.
Pots
Free recycled pots and plastic labels will be available for you at the Arboretum. Staff and volunteers can direct you to them during normal office hours or call if you need other assistance – 610-328-8025.
Propagation Resources
You can of course do species-specific web searches on a dividing or propagating your individual plant selections. Below are some good general University articles on methods and timing of propagation. We also have useful references at the Scott Arboretum library including the American Horticultural Society Book of Plant Propagation.

Labeling
Please include the Latin name on your labels. Specificity helps.
Hemerocallis—Yellow Daylily is acceptable, but if you know it to be H. ‘Golden Chimes’, please let everyone know.
Pencil weathers well on labels; if you use a pen please make sure it is waterproof! A brief description or a photo printed from your computer will make your plant, and you, very popular.
