Plant Samples

Due to the threat of Boxwood Blight, Rose Rosette and other serious pest/disease issues, the Garden is no longer allowing plant samples to be brought in for identification or diagnosis. These problems can spread to the garden displays and severely impact our living plant collection.

Please help us protect our plants by taking clear photos of the plant you need identified or diagnosed. Images can be emailed to plantinformation@mobot.org or brought to the Plant Doctors at the Center for Home Gardening (Open every day, 9 am - 5 pm).  

For any additional questions regarding samples, please call: 314-577-9562.

Seasonal Gardening Tips

Pinch azaleas and rhododendron blossoms as they fade. Double flowered azaleas need no pinching.

Don't remove spring bulb foliage prematurely or next year's flower production will decline. 

Continue monitoring pines, especially Scotch and mugo for sawfly activity on new shoots.

Plant summer bulbs such as caladiums, dahlias, cannas and elephant ears.

Set out tomato plants as soils warm. Place support stakes alongside at planting time.

Watch for striped and spotted cucumber beetles now. Both may spread wilt and mosaic diseases to squash and cucumber plants.

Don't spray any fruits while in bloom. Refer to local Extension publications for fruit spray schedule.

Do not prune apples and other plants susceptible to fireblight at this time of year. The bacteria can be spread through pruning equipment and cause new infections.

Prune unwanted shoots as they appear on fruit trees.

Birds eat many insect pests. Attract them to your garden by providing good nesting habitats.

Be on the lookout for bagworms. Larvae begin emerging late May to mid-June.
