Horticulture Expert Shares Tips for Bulb Care and Weed Prevention

Most years, spring signals the start of a colorful garden and a host of blooming flowers.

Yet, at this point in the season minimal care is needed for spring-flowering bulbs, says Kansas State University horticulture expert Cynthia Domenghini. To enjoy blooms in April, Domenghini suggests following simple care tips to ensure roots are taking in the nutrition to support future growth.


Before new leaf buds open (bud break), roses should be fertilized and pruned.

“April is a great time to plant new roses in the landscape as well,” says Domenghini. “Specific maintenance practices vary based on the classification, or type, of rose.”

Domenghini recommends tips from the Growing Roses publication.

How to Effectively Onboard New Employees

Easter Lilies

Containerized lilies are common in the spring as they are used to celebrate the Easter holiday.

“This perennial bulb can be grown in the landscape to enjoy for years to come,” says Domenghini.

The Easter Lily Fact Sheet provides care instructions.

Henbit and Chickweed

Henbit weed is in bloom, creating waves of purple through the landscape.

“Weeds drive most gardeners crazy, but many weeds provide food for pollinators,” says Domenghini. “Henbit is one of the first sources of pollen and nectar for honey bees and bumble bees after the long winter.”

Henbit and chickweed are winter annuals that germinate in the fall but become more noticeable in the spring, Domenghini adds. Treating these weeds is best done by applying a pre-emergent in the fall.

“Controlling for these weeds this time of year is much less effective,” Domenghini says.

Manual removal is recommended if the plants can’t be tolerated in the landscape.

The Henbit and Chickweed Fact Sheet provides tips for prevention and management in the spring.

Grassy Sandbur

Another annual — grassy sandbur — is a grassy weed commonly found in lawns, and spreads profusely as the stickers produced attach to clothing and pets.

“Maintaining a dense lawn is the best defense against this weed,” says Domenghini.

Alternative solutions can be found in the Grassy Sandbur Fact Sheet.
