What to Know About Holiday Plants

To kick off this year’s holiday season I plan to add come color to cheer up my houseplant selection. Sometimes I give friends and neighbors a holiday plant but I need to keep in mind if they have small children or pets as some of our favorites are toxic. Here’s what to know about those colorful plants available for the holidays.

Some years I have paper white narcissus decorating my house during the holidays. At other times I’ve had a pink jasmine wreath or one with holly, ivy and evergreens inside. Lovely cyclamen plants are available everywhere as are poinsettia. Christmas cactus are blooming at this time of year also. Which of these plants do I need to watch out for?

The classic plant to decorate our homes at this time of year is the poinsettia. Are poinsettia poisonous? Ohio State University conducted extensive research and concluded that although poinsettia sap from leaves and flowers might give you a stomach ache if you ate them they won’t seriously hurt you. The sap may cause a rash if it comes in contact with the skin on some people. With this in mind, you should keep poinsettia plants out of the reach of curious pets and small children.

Poinsettia do hold up well either as a cut flower or a living plant. Mostly it’s too cold here in the mountains for poinsettia to survive outside at night being native to Mexico but they thrive in the warmth of the house. They need a bright spot and the soil should be allowed to dry slightly, but not completely, between waterings. Deprive them of either of these requirements and the lower leaves will yellow and drop. Also be sure they aren’t sitting in water at the bottom of the container. Poinsettia are brittle and if you break off a branch, sear the end of the stem with a flame and it will hold up quite well in a vase or arrangement.

According to the Pet Poison Helpline cyclamen are mild to moderately toxic to dogs and cats if ingested but it’s the root or corm that is especially toxic if ingested in large quantities. Pets and people react differently and it is unlikely that children) would eat the corm and be affected.

My beautiful amaryllis flower and leaves are safe but the bulb is toxic. Amaryllis bulbs contain the same alkaloid that is found in narcissus and daffodil and is the reason deer know to leave them alone. Ingesting a small amount will produce few or no symptoms, however.

Azalea leaves are toxic and should be kept away from pets and small children. Holly berries are toxic if eaten in large quantities. Same for mistletoe, ivy and pink jasmine. Christmas cactus are safe except the berries from a pollinated flower.

Mistletoe contains multiple substances that are toxic to both dogs and cats. It can cause severe intestinal upset as well as a sudden and sever drop in blood pressure, breathing problems and even sometimes hallucinations. If a large amount of mistletoe or ivy is ingested, seizures and death may follow. The leaves and berries of holly and mistletoe plants, even dried, should be kept well out of your pet’s reach.

You can spray a plant with cayenne pepper dissolved in water if your pet is especially persistent to discourage them. While serious complications aren’t likely with holiday plants it’s still best to keep them away from small children and out of your pet’s reach.

Happy Thanksgiving from The Mountain Gardener

Once upon a time when our area was under water
there were no parks or trails or trees or gardens.
I’m thankful that our mountains rose from an ancient ocean
so we could enjoy this beautiful place we call home.

I’m thankful for the Big-Leaf maples
that shower me with leaves as big as saucers
as I walk in Henry Cowell along the river trail
and for the giant redwoods that sprouted long ago
at the time of he Mayan civilization.

I’m thankful for the Five-fingered ferns that grow lush along
the lower parts of Fall Creek
and for the canyons, hiking trails and small waterfalls
that feed the year-round creek.

I’m thankful for the Felton Covered Bridge
that overlooks the San Lorenzo River
and for the sound of children laughing as they play in the park.

I’m thankful for the western turtles who live at the Quail Hollow pond
and for the unique sand hills, grasslands and redwoods, too,
and for the plants, birds and other small creatures that live only there.

I’m thankful for Bonny Doon where you can see both the Pacific Ocean
and the San Lorenzo and Scotts Valleys
and for the resilience of the people recovering after the fire
on the mountain made of sandstone and shale.

I’m thankful that Big Basin State Park, where redwood sorrel, violets and mountain iris
once covered the slopes and lush canyons and
is recovering as are the salamanders, banana slugs, marbled murrelets
and red-legged frogs who make it their home.

I’m thankful for the whisper of the wind blowing across the water at Loch Lomond
and for the gentle whir of fishing reels at the edge
of thick tanoak, redwood and madrone.

And finally, I’m thankful for friends and family and neighbors who share all this with me.
There’s always something to be grateful for. I wish you all a Happy Thanksgiving.

Propagating Plants & Tips

Pin down rhododendron branches to make new plants.

Warm days, short days, cold days and hopefully rainy days – all in the fall of the year here in the Santa Cruz Mountains. It’s part of what makes our area so special to us. We are inspired by Mother Nature and our mountains. We feel a connection with nature as we enjoy our gardens. There are some easy things you can do at this time of year to extend that enjoyment. Gardening should be fun, too.

Taking cuttings of shrubs is a relatively easy and economical way to make new plants. Some plants that can be increased by hardwood cuttings include manzanita, coffeeberry, crape myrtle, pittosporum, euonymous, forsythia, spirea, viburnum and roses. Edible plants like currants, figs, grapes and quinces also make good subjects.

For deciduous plants it’s best to take cuttings soon after the shrub drops leaves and goes dormant. Evergreen shrub cuttings can be taken now. Start by taking cuttings of year old wood that’s about a quarter inch in diameter. Discard the top couple of inches of each stem since this unripened wood doesn’t have enough stored nutrients to survive. Cut the stems into 6-9 inch pieces. Because a cutting won’t grow if planted upside down, make the top cut at a slant, so you can keep track of it. Then dip the bottom ends in rooting hormone and tap off any excess.

You can store cuttings from dormant shrubs bundled and labeled in boxes of sand in the garage or outdoors in a well-drained trench. Each will form a callus at the base where roots will form next spring. Come spring, plant the cuttings in good soil in shade with only the top bud exposed. Water as needed and once the new plants develop leaves and increase in size, start feeding them monthly with a balanced fertilizer. By next fall your new shrubs should be well established and ready to be moved to their permanent place in the landscape.

Also you can simply pin down a stem of a plant like manzanita or rhododendron by putting a rock on it so the soil makes contact. After a year or so you will have a new plant that you can dig up and move. Other natives like ceanothus can be propagated in a peat and grit mix and will root in about 50 days if given bottom heat. Take these cuttings in January.

Stake trees if necessary. Trunks with leaning tops or those planted in very windy areas need support. To determine how high to place ties, move your hand up the trunk until the treetops straightens. I usually allow the stake to reach up into the canopy a bit so that a wind gust doesn’t snap off the trunk right at the base of the canopy. Tie the tree to the stake loosely in several places. Trees in containers are tied tightly to the stake but those in the ground should have some wiggle room to stimulate the trunk which will make it stronger. This is a good time to check existing tree stakes to make sure the ties aren’t digging into the trunk and the stakes are large enough to support your tree. Remember to keep your tree staked only as long as needed and then remove the supports.

Pick last roses and add alfalfa meal or pellets which will soak into ground and prepare them for next spring. Don’t prune until the end of January.

Groom strawberries and mulch to deter slugs in winter.

To help protect citrus from frost damage, pull mulch back from below the canopy. This allows the ground to absorb heat during the day and release it at night.
