Gather your thoughts ahead of time for successful shopping.

Think about the places in your yard where you might want to add plants.

For each of those places, think about the conditions: How much daily sun does it get in the summer?

What is the soil like? How much space is there?

Remember what has worked and not worked in the places you are shopping for.

Think about kinds of plants to look for that would suit your conditions.

Get a cardboard box when you enter. A volunteer will give you a colored sticker and write your number on the box.

Fill the box with plants.

Still shopping? Take your box to the table at the side of the room. Volunteers will give you another box and park your full box until you are ready to check out.

Need help carrying a box? Ask for a volunteer to help.

To check out, choose the checkout line corresponding to the color of your sticker.

After you check out, volunteers will be happy to help you get your plants to your car.

Plants are arranged in categories, such as Trees or Shade Perennials. Overhead signs show the location of each category.

Within each category, the plants are arranged alphabetically by their botanical names (for example, echinacea rather than coneflower).

For each plant, pots are arranged around a sign that gives pictures and information.

If there are no pots by a sign, it means that more plants of that kind are being brought from the growing facility. It is some distance away, so it may take 20 minutes to half an hour for the pots to arrive.

All the plants that are for sale have signs. If there is no sign for a plant, it is not available. Plants that were available in previous years may not be included in this year’s sale.

Plant Geniuses wear vivid yellow T-shirts. They are Arboretum experts who are happy to help you shop successfully.

Need help deciding on a plant? Have a problem you need a plant to solve? Not sure what the terms on the signs mean? Ask a Plant Genius.

The more you can tell Plant Geniuses about the conditions in your yard, the better help they can give you.

At the Arbor Day Plant Sale, plants for sale are arranged around a sign that identifies the kind of plant and gives important information about it. Use the sign to decide if the plant is right for your garden.

Follow this icon key to understand the plant identification sign.

Take your plants home and keep them in a cool, sheltered, shady spot. Don’t leave them out in full sun.

Water them well and water them daily while you prepare to plant them.

Trees, shrubs, and vines can be planted right away.

Perennials and herbs can be planted when nighttime temperatures are consistently above 50 degrees.

Tender vegetables, such as tomatoes and peppers, should not be planted until the risk of nighttime frosts is past, usually in mid-May. In the meantime, keep them in a sheltered place and cover them at night if cold temperatures are expected.

For trees and shrubs, follow this planting advice.

For perennials, dig a generous hole. Place the plant at the same soil level as it was in the pot. Refill the hole and gently firm the soil around the root. Water well and mulch over the root zone.

Do not fertilize trees, shrubs, vines, or perennials for the first year; there is slow-release fertilizer in the pot.

Vegetables and herbs, which are grown as annuals, will need fertilizer throughout the growing season. The Arboretum recommends slow-release fertilizer at planting.

All plants will need supplemental watering until their root systems are well established. For trees, that may mean supplemental watering for two to three years.

All plants benefit from a layer of natural mulch over their roots. For trees, make a wide, even layer 3 to 4 inches deep. For perennials and vegetables, make a layer about 1 to 2 inches deep.

Plant Geniuses can give you information on how to care for a particular plant.

The Plant Clinic is always ready to help gardeners and landscapers with plant questions. You can call, email, or visit. Consider taking the orange labels from the plants you purchased from the Arbor Day Plant Sale to the Plant Clinic to ask for advice on how to plant and care for them.

The Arboretum’s website has a wealth of information about selecting and growing trees, shrubs, and perennials.

All year round, the Arboretum offers gardening classes for every level of expertise.

Due to limited space, everyone is encouraged to arrive at their entry time for the best experience. Late arrivals may need to wait to enter, based on capacity limits at the time. Ticket holders will not be able to enter until their scheduled time.

Timed-entry tickets provide a better entry and shopping experience. This practice reduces wait times at the gatehouse, moderates available parking, reduces crowding at the sale, and makes the checkout process faster and more efficient.

The sale is in the Vehicle Storage Building near the Curatorial and Operations Center, southeast of the Visitor Center. The area is usually restricted to staff, but will be accessible to Plant Sale ticket holders. Signs and guides will direct you to the location and parking.
