Halloween Ideas from the Garden

Carved pumpkins will last a long time if they are carved from
a hole in the bottom, leaving the stem intact.

My little neighborhood goes all out decorating for Halloween. It’s fun to see what the kids have created with some simple supplies. I only have a small display with a pumpkin, colorful winter squash and mums along with some DIY ghosts made from dinner napkins. I do have lots of orange and rust perennials in my little garden. Here are some other tips for this time of year from the garden.

If you want to decorate for Halloween there is plenty of plant material you can harvest from your own garden or nearby woods. Manzanita branches can often be found on the ground and make great arrangements combined with nandina or other berries. Some of the trees have started to turn color and their leaves can also be used for wreaths. The leaves of New Zealand flax last a long time and add fall color in bouquets.

it’s time to bring in any plants that you plan to overwinter in the house. Whether they’re the houseplants that you put out on the patio for the summer or frost tender plants that you want to save, this is the time to bring them in and here’s why.

Although our nights are still above freezing, plants need to acclimate to the indoor environment before you start turning on the heater regularly. Be sure to wash them thoroughly and inspect them for any insects that may have taken up residence while they were vacationing outside. Usually you can dislodge any hitchhikers with a strong spray of water but if that doesn’t do the trick, spray them with a mild insecticidal soap or one of the other mild organic herbal sprays like oil of thyme.

Another tip: Fall is not a good time to prune. Wounds heal slowly, leaving them more susceptible to disease. As a general rule, don’t prune when leaves are falling or forming. Wait to prune most trees until late in the dormant season or late spring after leaves and needles form. To avoid sap flow on birches and maples, prune after leaves mature.

Several years ago a friend gave me a Blue Hokkaido winter squash to decorate my front entry and eat afterwards. It was delicious. Another year, I received a Cinderella pumpkin (Rouge viv d’Etampes) to decorate my front entry. It is said to have been the inspiration for Cinderella’s carriage. This French heirloom pumpkin was very popular during the 1880’s and will be tasty in pies and savory dishes later this fall. For now, the glowing orange-red color contrasts magically with the very pronounced lobes and flattened top.

Many gardeners feel the Cinderella pumpkin is the very best pumpkin to grow in your garden. It’s the first to set fruit, first to ripen and is mildew resistant. Their bright orange creamy flesh is perfect for baking. Oven roasted they produce a pumpkin puree that is neither watery or bitter. Delicious in pumpkin spice muffins, pumpkin soup, or with vegetables and sausage. I even found aa recipe for pumpkin mac n’ cheese baked in a pumpkin. I’m so excited.

Pumpkin was a staple food for the early pioneers. It was easy to grow as a few seeds dropped into a shallow hole grew into a mature fruit. Yes, technically they are a fruit not a vegetable along with summer and winter squash and gourds. Their thick rind would allow them to be kept almost indefinitely.

If you decide to grow the Cinderella pumpkin next year, you can start inside in pots or wait to plant in the ground when night temps are 55 degrees or over. In the garden, group them with other deep rooted plants that grow rapidly and need lots of water such as corn, cucumbers, melons and tomatoes.

Fun Facts about Fall Color

Eastern Dogwood showing off fall foliage

The weather has been perfect for us to have great fall color this year. Because it’s been warm during the day and chilly at night I’m looking forward to the show. Many trees and shrubs are already showing color because they are stressed from lack of water. Others will wait their turn and baring a wind storm which would dry out leaves before their time we’re in for a beautiful fall.

The vivid colors in a leaf are always there. They are just masked by the green chlorophyll which is busy making food by photosynthesis while the sun shines.

Come autumn, shorter days and cooler temperatures cause the trees to switch to energy-storage mode and their leaves stop producing chlorophyll. The leaves actually develop a corky later of cells between the leaf stalk and the woody part of the tree. This slows the transport of water and carbohydrates. The manufacture of chlorophyll is slowed and the green color of the leaves begins to fade, allowing the other pigments to show through. For the few weeks before the leaves fall to the ground, they are colored only by their natural pigments that have built up in the sap. Depending on the acidity of the sap – red and purple anthocyanins, yellow and orange carotenoids – fall foliage can be glorious, sometimes anyway.

I read that the fall color in the eastern U.S. is not quite as great this year due to their exceptionally hot and dry summer. The Rockies are rockin’ it this autumn because of the summer’s monsoon rains. And our own Eastern Sierra Quaking aspen show is in full swing.

Quaking Aspen

Quaking aspen (Populua tremuloides) is the most widespread tree species in North America. They generally grow in high altitude areas but also exist at sea level in high places along the Pacific coast where climate conditions are ideal. Quaking aspen provide food for foraging animals and habitat for wildlife. They also act as a fuel break retaining much more water in the environment than do most conifer species.

High mountain systems, such as the Sierra Nevada, are uniquely sensitive to global climate changes and act as “canaries in the coal mine” providing early signals of significant climate-driven changes. Research in the Sierra Nevada by Pacific Southwest Research Station, a USDA Forest Service research organization, shows how vegetation has responded to climate in the past and indicates changes that might be coming in the future over the next decade.

Climate has a profound influence in shaping our environment and natural resources. By looking at tree ring records of living and ancient wood and pollen lake sediments present, climate can be compared to historic patterns to show climate changes.

Research indicates a complex, unpredictable future for aspen in the West, where increased drought, ozone and insect outbreaks will compete with carbon dioxide fertilization and warmer soils with unknown cumulative effects. Aspen are vulnerable in the face of climate change. Hopefully, we will not lose this wonderful tree in California.

Lagerstroemia in fall color

Which plants put on the best show in our area? Here are some of my favorites.

California native Western redbud turns yellow or red in the fall if conditions allow. This plant is truly a four-season plant starting in spring with magenta flowers, then leafing out with apple green heart shaped leaves. Colorful seed pods give way to fall color. This small native tree or large shrub does well as a patio tree in gardens with good drainage.

Other California native plants like Western dogwood, Spicebush and Western azalea turn yellow, red or gold in the fall. A native vine that lights up with the onset of autumn is Rogers Red California grape. If you have an arbor, wall or fence that needs covering quickly this is your plant. The green and gray leaves are transformed in autumn into great draperies of rich, scarlet red leaves with clusters of summer fruit turning all shades of purple.

Trees and shrubs that also provide fall color include Eastern dogwood, Chinese flame tree, Ginkgo, Idaho locust, Chinese Tallow, Chinese pistache, crape myrtle, smokebush, witch hazel, all maples, liquidambar, katsura, Eastern redbud, sumac, crabapple, goldenrain, locust. oak leaf hydrangea and barberries.

Edibles that turn color in the fall include blueberries, pomegranate and persimmons.

Light up your garden as the light fades and the days shorten. Now through late fall is a good time to shop for plants that change colors because you can see in person just what shade of crimson, orange, scarlet or gold they will be.

Time to Plant Fall Bulbs

Plant tulips in sun or light shade

I’ve never had the perfect growing conditions for bulbs. I don’t get enough sun in the spring when the bulb is storing energy after blooming to ensure a good show the following year. I save last year’s bulbs and replant them hoping for the best but I get new ones each year so I’m not disappointed when spring rolls around and I get spring fever like everybody else.

This fall I’m thinking about planting those dramatic allium bulbs. Member of the onion family, their purple pom pom flowers are deer resistant, too. I see there is a variety with shorter stems which I think will be more successful given my partly sunny garden. Who knows? Maybe I’ll even have a stunning photo to share with you next year.

Who doesn’t love daffodils? I see there is a collection of more shade tolerant daffodils I might try this fall. I’m thinking they have might shorter stems which help them recover after a spring rain without having to be staked up. You remember spring rain? Fragrant miniature Hawera narcissus falls into this category. They are animal proof like all daffodils and naturalizes easily, too. Other bulbs for the shade include crocus, scilla, some tulips, grape hyacinth, leucojum, snowdrops, chionodoxa and lily of the valley.

There are so many types of tulips now. I’m always torn between classic Darwin tulips, parrot tulips and double flowering are spectacular also. There are the early blooming Fosteriana tulips and Lily flowering tulips which are elegant with graceful stems and goblet-shaped flowers with pointed reflexed petals. These are late bloomers and excellent for bouquets as are all tulips.

The ground is still a little warm to plant your bulbs. Best selection is now, however and you can store them in a cool, dry place. Most bulbs are pre-chilled before they are shipped. To make sure they have 12 to 16 weeks of chilling you can store your bulbs in the refrigerator set to around 40 degrees. Just be sure not to store them near any fruit as the released ethylene gas reduces bloom.

And in case you forget about them until after Christmas go ahead and plant them anyway. The stems will be shorter but that’s all. The flowers will still be beautiful.

Squirrels, mice and moles are observant and crafty. Once they discover newly planted bulbs, they’ll assume it’s food. Just disturbing the earth is a tip off for them. Daffodils and narcissus bulbs are toxic but if they dig them up then leave them exposed with just a nibble taken, so much for any spring flower display. Protect your bulbs with wire baskets or spray them with foul tasting repellent, letting the spray dry before planting. You can also bury the bulbs with ground up egg shells. Another way to foil squirrels is to plant the bulbs deeply, This only works if you have good drainage, however. Next year, if the squirrels start nibbling the foliage as it emerges try spraying it with hot pepper spray.

Whatever you bulbs you choose to try this fall, you will be happy you planted some bulbs come spring. And to help them bloom again the following year fertilize them at the time of planting with bulb food or bone meal worked into the soil a couple inches at the bottom of the hole. Mature bulbs respond to an early spring feeding with the same fertilizer.
