We are getting close to the typical average last frost date at March 3rd. So now is the time to start some cucumber, squash or melon seeds indoors.
Starting Mix
First, you need some seed starting mix. You can use ready-made mixes, or you can make your own by using potting soil mix you have on hand. Since I always have some potting soil mix on hand for use in containers or up potting starts, I use that. I suggest screening it through a ¼ inch hardware cloth sieve to take out any larger pieces which might block the seeds from poking through the mix.
Once the soil is hydrated, add it to the seed trays. Since cucumber, squash, and melon seeds are larger seeds, they are planted at about twice their size or roughly ½ inch depth.
Next, place your starter tray on a rack or designated place, covering it with a humidity dome. If you have plant-start heating mats, they can be very helpful by warming the soil, but are not absolutely necessary. It is customary to “bottom” water seeds, so add water to the tray your seeds are in. The soil should be moist enough from the initial wetting process described above, thus only a little water should be needed in the tray. Add water only when soil dries out slightly. After about 15 minutes, if any water remains in the tray, drain it. The humidity dome should stay on until the seedlings begin to show.
Seedlings
The Armenian cucumber seeds in these photos germinated over five days from February 17th through the 22nd with the humidity dome being removed on February 22nd.
At this point the seedlings should be placed under grow lights slightly above their height. Adjust the height of the light as the seedlings grow. If the grow lights are too high, the seedlings will likely become “leggy,” because they are stretching to reach more light. This will cause them to be weaker due to the main stem being too long and thin, and likely top heavy. The first set of leaves on the seedlings are the cotyledon leaves. The next set of leaves you will see are the first true leaves and the cotyledon leaves will likely drop off.
Preparing Plants for the Garden
Hardening off is the process of acclimating the new seedling to the outdoors. This starts by moving them outdoors the first day for perhaps 2 hours. This continues daily, increasing amount of time of outdoor exposure each day for about 1 week. By then your new starts should be able to handle being transplanted into your outdoor garden.
If you prefer not to jump start your growing season by starting seeds indoors, cucumbers, squash, and melon seeds can be started in the ground in late March. Just be sure to check the long-range weather forecast to see if any possible freezing temperatures might happen.

In years past, I would get bitten by mosquitoes when out late at night. But in the past decade, I've been bitten frequently during the day, and this year seems to be particularly bad, possibly due to favorable weather conditions for mosquitoes.
Invasive Mosquitoes
West Nile Virus
How can you protect yourself?
Although day biting mosquitoes can bite through clothing, it can help reduce bites. You can also wear an application of repellent underneath. The CDC recommends using an insect repellent containing the active ingredients DEET, Picardin, IR3535, or the plant-based oil of lemon eucalyptus. Please note, the last active ingredient is not an essential oil.

Learn about planting leafy vegetables like lettuce and spinach, and root vegetables like carrots, beets and radishes. Not to mention broccoli and cauliflower. All of these vegetable plants can be grown in the ground or in containers. Great class for beginning gardeners.

Did you know? Fruit trees can be kept under 6' tall so you can easily access the fruit. Surprisingly, although the trees are small, you will still get plenty of fruit!
UCCE Stanislaus County Master Gardeners hope to see you at a local Stanislaus County library branch to learn more.

Backyard Orchard:Growing deciduous fruit trees is not for the faint-hearted. Trees such as apples, apricots, plums, pears, peaches, cherries, are not all pruned or managed the same way. Winter is the best time to plant a fruit tree, as you can purchase them as “bare root” fruit trees at a lower cost. You will learn how to correctly plant a bare root fruit tree, and how to prune it in the future to keep it small. This class does not include citrus, a separate class taught next spring.
Due to holidays conflicting with class dates, this class won't be offered at Riverbank, Oakdale, and Modesto Library locations.

*Unfortunately, deciduous fruit trees that lose their leaves like apple, plum, pear, apricot, and cherry, have root systems that grow too large for containers. Luckily, you can plant many citrus tree varieties in containers.
