Zoo Blooms has ended, but there is still plenty to see at the Zoo’s Botanical Garden! After the tulips peak bloom is over, the work really begins! Volunteers are taking over the grounds this week in an effort to dig up the once blooming tulips and begin to plant some of the region’s top rated annuals.
Why do we dig up our tulips and sell them you ask? In order for tulips to bloom to their fullest each year the leaves should die back to the ground before they are removed. Now picture that throughout the Botanical Garden for 2-3 weeks. Beds full of dying foliage. Not exactly what our guests are hoping to see! These display beds are the “floral welcome carpet” to visitors and we want them to say WOW. In order to have the best possible growing conditions we till the beds and add organic matter to the soil. Then we plant the best annual trials in the Midwest.
Why don’t we keep the bulbs and replant them? Storage is a major issue. First we would have to let the foliage dieback and the conditions for storage require a cool dark area with plenty of airflow. If you have ever come to our shop during tulip digging time and have seen the huge amounts of bulbs, it’s easy to understand we would need a warehouse. So the solution has been to sell them to the public, allowing our guests to have the opportunity to enjoy the beauty of flowers in their home landscapes and using the proceeds towards the cost of next year’s bulbs. We plant over 100,000 bulbs each year, so selling the bulbs helps to offset that cost.
This year, the Zoo will be selling the bulbs on the spot as volunteers and staff digs them up. Sale times will be 10am-noon (weather permitting). The Tulip Hotline number to call for updates on digging locations and bulb availability is 513-475-6102. We will update daily where we are digging. Tulips are $5 a bag.

Spring has sprung at the Cincinnati Zoo, and so have the Carpenter Bees! However, the Zoo’s Curator of Invertebrates, Winton Ray, has some comforting news for you. It’s time to stop fearing the bee. At least the Eastern Carpenter Bee!
The Eastern Carpenter Bee (Xylacopa viginica) is the large, yellow and black flying insect frequently encountered on Zoo grounds at this time of year. Though they are often mistaken for Bumblebees they can be most easily differentiated from them by their black, hairless abdomens; Bumblebees have fuzzy abdomens. Carpenter Bees were so named because the females excavate nest tunnels in wood. They only nest in the wood, they do not eat it. And while nesting bees can sometimes damage wooden structures the damage associated with them is sometimes caused by woodpeckers working to excavate the bees themselves for food.
Carpenter Bees are among the first insects observed in spring. The Carpenter Bees Zoo guests are generally encountering are males. Male Carpenter Bees can be easily distinguished from females by the white or gold patch between their eyes. Each male stakes out a territory in the vicinity of a nesting female awaiting the opportunity to breed. Any other males entering the territory will be chased away and just about anything will be investigated. It’s these investigative flights that bring them into close proximity with you, the innocent bystander zoo guests. Carpenter Bees are large and fast flying so it’s easy to see why people mistake their curiosity for aggression even though they’re essentially harmless. Male Carpenter Bees, like all male bees or wasps cannot sting. Let me repeat that: they cannot sting! The stinger is a modified ovipositor (egg laying organ). Female Carpenter Bees are capable of stinging but rarely do. They spend most of their time visiting flowers or in their underground nest tunnels.
In a few weeks the Carpenter Bees we’re seeing will be gone but in the tunnels they’ve created their offspring will live on. In late summer young Carpenter Bees will emerge to feed on nectar in preparation for a long winter hibernation. They’ll generally hibernate in the same tunnels their ancestors survived previous winters in. Carpenter Bees on Zoo grounds are going about their lives the way they have for countless millennia, they’re just doing it at the Zoo instead of in an Eastern forest.
So, good news for your next Zoo visit! Carpenter Bees pose essentially no danger to us. You’re actually more likely to be injured trying to swat or flee from Carpenter Bees than by the bees themselves. Next time you see a Carpenter Bee, you can let your friends know, there’s really nothing to fear!

Growing up, my favorite place to escape was among the weeping branches of a willow that stood in the far corner of our yard. I spent hours climbing that tree, watching the ants march up and down its wrinkled bark and making crowns of its leafy branches. Still now when I return to my childhood home for a visit, I always stop by to say hello to my old friend.
In our everyday lives, we generally pay little attention to the trees that grow beside us, providing the oxygen we breathe, cleaning the water we drink and shading the homes in which we live. And when we think about deforestation and the need to protect and plant trees, we usually picture far away tropical jungles. But right here in Cincinnati, we live in the middle of what used to be one of the world’s great forests, the Eastern woodlands.
When Ohio became a state in 1803, more than 95% of its land was covered with forest teeming with wildlife including black bears, wolves and bison. As settlers moved in, they cut down forests to farm. Less than 10% of Ohio remained forested by the early 1900s. Gradually, people became concerned about protecting the environment and forests began to reclaim some of the land. Today, more than 30% of Ohio is forested and wildlife populations are the healthiest they’ve been in the last century. Many species, such as the deer and turkey, have recovered fully, while others are well along the path to success, including the river otter and bald eagle.
With exotic insects like the emerald ash borer sweeping through the region killing trees, invasive plants like bush honeysuckle choking out native species and ongoing destruction and fragmentation of woodlands, there is still much recovery work to be done, and the Taking Root campaign is asking us all to get involved.
Chaired by our one of our own horticulturists, Scott Beuerlein, Taking Root is a collaboration between the Cincinnati Zoo & Botanical Garden, the Ohio Kentucky Indiana Regional Council of Governments, the Green Partnership for a Greater Cincinnati and the Green Umbrella along with many other great organizations. Founded in 2013, the campaign’s goal is to plant 2 million trees by 2020 – that’s one tree for every person in the tri-state region.
More than 83,945 trees have been planted and registered with Taking Root so far.
You can help get the numbers up by planting trees in your yard or joining a tree planting event – check the website for a calendar of events.
Take the Tree Planting Challenge! It’s as easy as 1-2-3.
1) Plant and register a tree on the Taking Root website, or donate to the Taking Root Tree Fund.
2) Make a video of yourself challenging friends, family, or colleagues to do the same. Check out Zoo Director Thane Maynard’s video.
3) Post your video on Facebook or other social media and link it to the Taking Root Facebook page.
You can also nominate a special tree in the tri-state region to be listed on the Zoo’s website as a Tree of Merit. Here at the Zoo, we have a particularly special red oak, Quercus rubra, that was likely here before the Zoo was even established. At more than 130 years old, it is quite impressive. It grows in the central lawn area between Swan Lake and the Reptile House. Next time you’re at the Zoo, be sure to stop by and marvel at this beautiful elder. Imagine all that has changed around it during its lifetime!
