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.

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.

Labeling

Please include the Latin name on your labels. 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.
