How The Magic Happens - Producing a Plant Sale

Sue Fitz, UC Master Gardener, Yolo County

Photos by Wilda Knoesen


The bi-annual UC Master Gardener-Yolo plant sales at Woodland Community College (WCC), have been occurring for almost twenty years. Partially a fund raiser for the college and Master Gardeners, it also aims to be an inexpensive source of waterwise and pollinator friendly plants for the public. 


The preparation for each sale begins about five months before the sale date. The propagation team meets to choose what plants to offer for the upcoming sale. To keep things interesting, species and varieties are rotated frequently, to keep selection fresh. Propagators keep an eye out at all times to spot new material that can be added to the list of offerings.


Four months out from the sale, equipment is disinfected and sterilized. Pots, soil, and labels are ordered, heat mats are unfurled, and the sterilized trays are filled with a fifty/fifty mix of perlite and vermiculite. Seed pans are filled with either regular potting soil, or cactus mix (used for starting native plant seeds) and...

Tomato Leaf Shapes and Sunscald

Tanya Kucak, UC Master Gardener, Yolo County


The typical tomato leaf is called a regular leaf shape. Some tomato growers favor potato-leaf varieties, opining that the larger leaves of these varieties result in better flavors and offer the tomatoes more protection from the sun. The leaf margins are smooth rather than toothed, somewhat reminiscent of the leaves of potato plants. Brandywine is the most popular potato-leaf tomato. Other potato-leaf varieties include African Queen, Polaris, and Rosedale. Since the potato-leaf gene is recessive, these plants are far less common than regular-leaf varieties. 


Rugose potato-leaf foliage is another variant. Dwarf tomato plants, such as Dwarf Golden Tipsy, have deeply creased, or rugose leaves. 


The smaller regular leaves of a plant such as Fire Plum F1, however, can be just as effective at protecting fruits from the sun. Although the plant has an airy appearance, its leaves are layered.


Tomato plants that don’t provide enough leaf cover can make their fruits more susceptible to sunscald. At the height of summer, sunscald looks like a bleached-out, somewhat wrinkly patch on the tomato. If you...

Eleven New Varieties in Tomato Seedling Sale

Tanya Kucak, UC Master Gardener, Yolo County


This year’s lineup for the tomato seedling sale includes nine new-to-the-sale varieties, two heirlooms from previous years, and twenty-five varieties carried over from last year.


Rosebud, Rosedale, and Texwine were bred by Bill Jeffers in Indiana. He specializes in vigorous, heat-tolerant, disease-resistant varieties. Moreover, he has collaborators in other parts of the United States, especially where heat is more intense, who make selections and help refine his original crosses. These varieties are all open-pollinated, which means that you can save seed from your tomato and, as long as a rare bee cross did not occur, it will breed true. It also means that it has taken at least seven years to develop a true-breeding variety. The first year, the original cross is made, which produces F1 seed. Many seeds collected from the F1 fruits are grown the next year, the F2 generation, to find promising variants. The best of the F2s, selected for different qualities, are then each grown out the following year, and the best of these are each selected as F3s. It takes seven or eight generations (F7 to F8) for a variety to be...

QUESTION: I want to start a vegetable garden. What do I do?

QUESTION: My shade trees have dropped a lot of leaves in my yard. Is there anything I can do with them besides put them in the street for pickup?


ANSWER: As you probably know, when you leave your leaves on the street, the county picks them up, shreds the material and puts it through a composting process, and then sells that finished compost to local farmers. Some of the compost...

March Garden Tips

Peg Smith, UC Master Gardener, Yolo County

Photos by Peg Smith, adapted


March is such a wonderful month for gardeners, spring glory is erupting in brilliant blossoms and flowering bulbs. As we enjoy the bursting buds and blossoms it is an ideal time to look forward to the summer bounty of vegetables and flowers. Time to start annual and perennial summer flower seeds so they are ready to transplant out into the garden as the spring annuals fade.

 

General maintenance

With the February rains and the warming temperatures mosquitos are emerging to lay eggs in any standing water – even a capful of standing water. The life cycle for the mosquito is egg, larvae, pupa to adult, with the egg, larval and pupal stages taking place in water. Male mosquitos have short lifespans and do not consume blood from birds or mammals. The female mosquito needs a ‘blood meal’ to...

March can come in many weathers: from wet, to freezing cold, to a warm spell. It is a month for vegetable gardeners to be patient. Hold off on the planting of warm season transplants of tomatoes, peppers, eggplants, etc. that were started in January or February. If the soil is not sufficiently warm transplants will not progress but will remain static until the temperatures...
