May 2012 Tips & Events
from the UCCE Santa Clara County Master Gardener Program
"Spring is Nature's way of saying, "Let's party!"--Robin Williams
Straw from the local feed store can be an inexpensive, effective mulch
As the ground heats up, keeping moisture in the soil is crucial for a healthy garden. See more benefits of straw in this article on different kinds of mulch. An added bonus: worms love straw!
Nuture your soil between plantings too
Even if you have nothing planted currently, treat your soil well. In order to keep the soil healthy, it still needs water. You can bury some kitchen vegetable scraps, or incorporate a thin layer of grass clippings (grass clippings that are applied too thickly can create a mat-like barrier) under a thick layer of mulch. Decomposing leaves are a great addition to an empty raised bed.
Be on the lookout for bee swarms
As the weather warms up, bees are more likely to swarm. If you see a swarm, enjoy the sound and beauty first, then call us at the hotline number below (Monday-Friday 9:30-12:30) or contact the Bee Guild. We want your swarms! Bees swarm for a few reasons, but they are all looking for a new place to call home. Bees that swarm are loaded with food and are not interested in stinging people.
Brush up on UC lawn care recommendations
The UC Guide to Healthy Lawns will remind you how much you should be mowing among many other suggestions for a healthy lawn.
Good ideas for companion planting
This article from Cornell University's Department of Horticulture will likely interest most of you: companion planting. An excerpt: "plants change the chemistry of the soil, and influence the types of microorganisms that grow there. They actively compete with other plants for space. Some will poison their neighbor's offspring to maintain a competitive advantage, while others change the environment in ways that benefit other species."
Pay particular attention to watering plants after you put them in the ground
While they will need less attention (and water) once the roots are established, keep a closer eye on the newly planted as the weather warms.
Time to check apple and pear trees for signs of fire blight
This bacterial disease most commonly occurs on blossoms or newly formed shoots and can cause irreparable damage if not controlled. Look for a watery, light tan ooze that exudes from cankers, and for wilting tips on new branches. When found, prune affected parts cutting six to eight inches below the infection. Check the link for pictures.
Wait until after Spring and early Summer to trim your trees
Birds are nesting right now. The babies often don't survive a fall and many die on the ground. Hundreds of birds are brought to the Wildlife Center of Silicon Valley
. Those birds will never learn to sing, find food, or avoid predators. Fortunately, trees respond better to dormant pruning anyway. If you're going to prune, check the tree for wildlife before you work and refer to pruning information
(PDF) on the UC Center for Landscape and Urban Horticulture website.
Plant large-podded peppers in the same hole
By planting peppers together, not only will you get more peppers per square foot, but the peppers will support each other, look lush and beautiful, and protect each other from sunburn. After planting, you also might want to remove flowers and fruit from the large-podded plants the first four to six weeks to encourage deeper roots and more foliage. Learn more pepper tips by consulting our handout on Growing Great Peppers (PDF).
Tomato Planting Time!
The ground is warming up and it should be about time to plant your tomatoes. For Master Gardener Tomato Tips, see our Growing Great Tomatoes
(PDF) one-page reference! For common problems, consult the UC pest notes on tomatoes
If you want more bees in your garden, plant annuals such as Cosmos or simply allow your herbs to flower
With few exceptions, fruit will not form until pollen from male parts is transferred to the female parts of a flower. Without pollination
, flowers may bloom abundantly, but will not bear fruit. Some plants
are better at attracting bees and other pollinating insects and animals than others. Give your fruit trees the gift of an insect-friendly environment and give your family a better harvest! We have a culinary herb event (in San Jose
) this month to get you started!
