Learn about our seedling giveaway

We will be giving away free tree seedlings to visitors at the Cleveland Botanical Garden on Arbor Day, while supplies last. See info and plantings tips below.

Squirrels love hazelnuts, and we think you will, too! 

Mature size: 15-18 ft 

Growth rate: 13-24 in/yr 

Site selection: Tolerant of a wide range of soil conditions, but not standing water. 

Light conditions: Full sun for best production, tolerates shade. 

This highly ornamental tree in the bean family is an essential source of nourishment for native pollinators early in the year. 

Mature size: 20-30 ft 

Growth rate: ~1 ft/yr 

Site selection: Medium to moist soil 

Light conditions: Full sun to part shade 

This adaptable native oak is very well-represented in Holden’s collections, with around 45 accessioned trees spread across both campuses. 

Mature size: 60-70 ft 

Growth rate: ~2 ft/yr 

Site selection: Dry to medium soil ranging from circumneutral to acidic.  Tolerates clay.  No standing water. 

Light conditions: Full sun to part shade 

Like other oaks, white oak is an ecosystem engineer, providing food and shelter for hundreds of species of plants and animals.  

Mature size: 60-100 ft 

Growth rate: ~1 ft/yr 

Site selection: Well-drained soil.  Intolerant of extremely dry soil. 

Light conditions: Full sun to part shade 

Serviceberries are among the tastiest of Ohio’s native fruits.  Good luck beating the birds to the crop, though! 

Mature size: 15-25 ft 

Growth rate: 1-2 ft/yr 

Site selection: Moist well drained soils 

Light conditions: Full sun to part shade 

Keep the soil with your seedling moist but not wet. Keep your seedling out of direct sunlight in a cool location until you are ready to plant. Ideally you will be able to plant your seedling before the leaves are out. If your plant has started leafing out, place your seedling outside in partial shade for two to three days before planting to acclimate it.  

If the soil is infertile, amend it with about 10% composted organic matter. Plant your seedling at a level where one of the uppermost roots can be seen. Make a doughnut-shaped berm of soil 2 inches tall and 1 foot in diameter around the base to facilitate watering. Do not place mulch by or touching the stem. Water about every 3 days; after 2 months water about once a week. A slow-release fertilizer is mixed into the potting soil with the seedling. No additional fertilizing is needed through the summer.  

You may surround your seedling with an 18-inch diameter cylinder of metal mesh (chicken wire or hardware cloth) to exclude rabbits and mowers. The mesh cylinder can be tied to two wooden stakes driven into the ground inside the cylinder. If deer are present, cap the cylinder with mesh. 

What to see and do on Arbor Day

VISIT A JESSE OWENS OLYMPIC OAK

The Jesse Owens Olympic Oak Plaza in Cleveland includes public art installations, a memorial to Jesse Owens, and a newly planted Olympic Oak tree. The tree is genetically identical to one of the four trees awarded to Jesse Owens in the 1936 Olympic Games in Berlin.

PLEDGE PEOPLE FOR TREES™  

Holden Forests & Gardens is entering year three of our People for Trees campaign to have 15,000 trees planted in Northeast Ohio by 2025. Already, more than 10,000 trees have been pledged, and planted and given away. But we still need more People for Trees to pledge and plant. Share your love of nature and invite a friend, neighbor, and family member to join us. Pledge at holdenfg.org/people-for-trees
