Petal Power! Punch Up Your Palate With Edible Flowers
UC Master Gardeners Blogs

Most edible flowers are best eaten as soon as possible after picking, preferably fresh from your own garden. If you won't be using them right away, wrap the flowers lightly in a damp paper towel and place in the produce section of your refrigerator where they will keep for 2-3 days. There are many varieties of edible flowers you can grow in your own garden such as nasturtium, chives, purslane, chamomile, calendula, anise hyssop, pansies, and sunflowers. Read more.

Grow Cover Crops to Attract Beneficial Insects
UCANR

The benefits of cover cropping include reduced soil erosion, adding organic matter, nutrients, and mycorrhizae to the soil, and weed and nematode suppression. Cover crops also increase nutrient retention and water infiltration. And some, such as radish, break into compacted soil layers, making it easier for the following crop's roots to develop more fully. Flowering cover crops on farms also increase beneficial insects, including bees and natural enemies, that provide pollination and pest control services in crop production. Read more.

How to Save Seeds
Seed Savers Exchange

Not all plants flower, set seed, and die in a single growing season. Those that do, like lettuce, tomatoes, and peppers, are called annuals. Biennials, such as carrots and onions, don’t flower until their second growing season, after they have gone through a cold period. Some long lived plants, like apple trees and asparagus, are perennial, surviving and flowering for many years. Seeds are happiest when they are stored in a cool, dark, and dry place. A dark closet in a cooler part of the house or a dry, cool basement are both good spaces to store seeds for a year or two. Once properly dried, seeds can also be sealed in airtight containers and stored in the refrigerator or freezer for several years. Read more.
