Popular arboretum guide starts his monthly series
It’s a new school year and a new season of exploration through the UC Davis Arboretum with everyone’s favorite pun-spinning garden guide, Warren Roberts.

At noon Sept. 11, join Roberts for his popular “Walk with Warren,” a lunchtime stroll in search of blooms and more. On this walk, he’ll discuss the change of seasons in the gardens including fall flowering bulbs and shrubs.

As superintendent emeritus, Roberts has a unique perspective of the arboretum gardens; he knows the full history of thousands of the arboretum's plants, where they came from, what they like, how they grow and why they were chosen for the collection. He probably has an entertaining story for every plant, too.

Meet at the Arboretum Gazebo. As always, admission is free. One-hour free parking is available along Garrod Drive near the Gazebo. Or stay longer and park in Visitor Parking Lot 55; a parking pass is $10.

Wear comfortable shoes and, if it’s particularly sunny, a hat and sunscreen. See how the arboretum’s water-wise gardens survived (and thrived) this summer and discover possibilities for your own landscape.

Roberts leads these Wednesday tours once a month. Become a "Walk with Warren" regular and really get to know this wonderful local resource.

Garden Checklist for week of April 21

This week there’s plenty to keep gardeners busy. With no rain in the immediate forecast, remember to irrigate any new transplants.

* Weed, weed, weed! Get them before they flower and go to seed.

* April is the last chance to plant citrus trees such as dwarf orange, lemon and kumquat. These trees also look good in landscaping and provide fresh fruit in winter.

* Smell orange blossoms? Feed citrus trees with a low dose of balanced fertilizer (such as 10-10-10) during bloom to help set fruit. Keep an eye out for ants.

* Apply slow-release fertilizer to the lawn.

* Thoroughly clean debris from the bottom of outdoor ponds or fountains.

* Spring brings a flush of rapid growth, and that means your garden is really hungry. Feed shrubs and trees with a slow-release fertilizer. Or mulch with a 1-inch layer of compost.

* Azaleas and camellias looking a little yellow? If leaves are turning yellow between the veins, give them a boost with chelated iron.

* Trim dead flowers but not leaves from spring-flowering bulbs such as daffodils and tulips. Those leaves gather energy to create next year's flowers. Also, give the bulbs a fertilizer boost after bloom.

* Pinch chrysanthemums back to 12 inches for fall flowers. Cut old stems to the ground.

* Mulch around plants to conserve moisture and control weeds.

* From seed, plant beans, beets, cantaloupes, carrots, corn, cucumbers, melons, radishes and squash.

* Plant onion sets.

* In the flower garden, plant seeds for asters, cosmos, celosia, marigolds, salvia, sunflowers and zinnias.

* Transplant petunias, zinnias, geraniums and other summer bloomers.

* Plant perennials and dahlia tubers for summer bloom.

* Mid to late April is about the last chance to plant summer bulbs, such as gladiolus and tuberous begonias.

* Transplant lettuce seedlings. Choose varieties that mature quickly such as loose leaf.
