Time for Bareroot Edibles

Bareroot fruit trees in their temporary home.

The other day I visited 3 local nurseries to see what’s new in their bare root edible selection. In addition to the classics I found a ton of new varieties for containers and smaller home gardens. Now is the time to add ornamentals and edibles like fruit, nuts, berries and vegetables while they’re available in bare root form. They are easy to plant, economical and establish quickly.

What first caught my eye at Mountain Feed & Farm Supply in Ben Lomond was the selection of blueberries for containers. I’d have a hard time deciding between Pink Icing, Jelly Bean or Peach Sorbet which is described as having summer leaves of peach, pink, orange and emerald green and grows only to 2 feet.

There are so many fruit trees now available for the home gardener. If you have limited space there are multi-graft trees that combine compatible pear, peach, apple, plum and nectarine. There’s even a “fruit cocktail tree” that combines totally different stone fruits.

Then the selection of miniature nectarines and peaches caught my eye. Scarborough Gardens in Scotts Valley also has a nice selection of these showy spring bloomers with delicious full size fruit including Necta Zee. This sweet, very flavorful yellow freestone has beautiful red skin, ripens in late June to early July and is self fruitful. Dwarf peaches and nectarines grow to about 6 feet making them perfect for the smaller garden.

The Southern Bartlett was found on an old Louisiana homestead and needs only 400 hours of chilling.

If you’ve always wanted a Bartlett Pear but didn’t think it would grow in your garden think again. I saw a Southern Bartlett at Scarborough Gardens. This chance sport needs 400 or fewer chilling hours and was found on an old Louisiana homestead, It is self fruitful.

Shop for your plants in January or February while they are still dormant. Once leaves emerge or flower buds start to swell, roots have already started growing. You want your tree to start developing new permanent roots in their final home. Stone fruits such as apricots, peaches, plums and cherries are going to start waking up first so they are best put in the ground soon. Fruit trees like pears and apples wake up later so you can wait a bit longer to plant those varieties.

What fruit tree varieties can you grow here in the mountains? Well, almost everything. Most of us get 700-900 chilling hours per winter. What does that mean? Well, many fruit trees, lilacs and peonies need a certain number of hours during dormancy where the temperature is 45 degrees or less. You can give the plant more chilling in the winter but not less. Those in coastal Santa Cruz can grow Fuji apples as they require only 300 hours of chilling but not Red Delicious. We can grow both. Late rains can knock blossoms of a low-chill tree that has broken dormancy but we gardeners bet on the weather cooperating all the time. Some years you win, some years nor so much.

What if you don’t get full sun where you’d like to grow fruit trees? Apples, pluots and plums are good choices for an area that gets some sun- at least 5 hours a day during the growing season. The ideal is full sun but these trees will still set and ripen some fruit in partially shaded conditions. With peaches, nectarines or apricots it’s a different story. These fruits need hot sun to develop sweet, tasty fruit. Too little sun and they will not deliver anything close to what you have in mind.

What’s the correct way to plant a bare root tree? Mountain Feed & Farm Supply in Ben Lomond has a great web site with all the information you need to get your new fruit trees off to a good start including planting, pruning, staking, mulching and care as they mature. Visit www.mountainfeed.com for all the information you need.

Don’t plant in heavy saturated soil with a high clay content, however. If your soil drains poorly it’s best to place your bare root tree at an angle in a trench, cover with soil and water in. Wait to plant until the soil is crumbly and friable with plenty of pore space. Digging in waterlogged clay soil is one of the worst things you can do for your soil’s health.

With a little planning you can have fresh fruit 7 months of the year. By growing your own fruit you’re not at the mercy of mechanical harvesters and shipping practices. You can grow fruit and harvest it when the time is right. Homegrown fruit is a world apart from agribusiness and much less expensive than the Farmer’s Market.

Plants that Fight Indoor Pollution

Parlor palms clean the air inside your home and are safe for pets.

Because of all the power outages recently, I’ve needed to set up a portable propane heater as well as start a fire in the fireplace to keep warm. I know even with ventilation there are lots of potential pollutants that have found their way into my home. For most of a winter day, our homes are closed tight with no windows or doors open to let out pollutants and let fresh air circulate. Toxins such as benzene, formaldehyde, and trichloroethylene can be released from furniture upholstery, carpets, cleaning products, paint, plastics and rubber. Carbon monoxide from the incomplete burning of wood and nitrogen oxides from cigarette smoke, vehicle exhaust and smog can also be present in indoor air.

Then there are airborne biological pollutants. These include bacteria, viruses, animal dander and dried cat saliva, house dust and pollen. House mites, the source of one of the most powerful biological allergens, grow in damp warm environments. Mold and mildew grow in moist places like central heating systems and are just one more source of indoor pollution.

Many common houseplants help fight pollution indoors. They are able to scrub significant amounts of harmful gases out of the air through the everyday processes of photosynthesis. The first list of air-filtering plants was compiled by NASA as part of a clean air study published in 1989 which researched ways to clean the air in space stations. As well as absorbing carbon dioxide and releasing oxygen, as all plants do, these plants also eliminated significant amounts of benzene, formaldehyde and trichloroethylene. Other studies added to the list of chemical pollutants and the best plants to remove them.

NASA researchers suggest that the most efficient air cleaning occurs with at least one plant per 100 square feet. Even the microorganisms in potting soil remove some toxins. Yikes, who knew all that was going on right under our noses?

Some of the easiest houseplants to grow are some of the best to have in the home. Just about all the potted palms are good. Also rubber plant, dracaena ‘Janet Craig’, philodendron, boston fern, ficus, peace lily, Chinese evergreen, spider plant, snake plant, pothos, English ivy and phalaenopsis orchids are high on the list of plants that fight indoor pollution.

If you have a cat of dog that you share your home with most of the above plants aren’t safe for them if they are chewers according to the ASPCA website. While all plants clean the air only ferns, spider plants, areca and parlor palms and phalaenopsis orchids from the above list are safe.

Other houseplants toxic for dogs and cats according to the ASPCA are asparagus fern, lilies, cyclamen, jade plant, aloe vera, azalea, begonia, ivy, mums, coleus, sago palm, kalanchoe and rubber plant. Keep your pets safe by keeping toxic plants out of reach.

Bromeliads clean the air inside your home and are safe for pets

There are many houseplants that are safe for cats and dogs and every plant photosynthesizes and cleans the air to some extent. Some of the common ones include African violet, aluminum plant, bromeliads, peperomia, areca palm, polka dot plant, cast iron plant, Christmas cactus, chenille plant, creeping Charlie, false aralia, Tahitian bridal veil, wandering Jew, goldfish plant, piggy-back plant and the succulents, donkey’s tail and hens and chickens.

With a little planning you can clean the air in your home while keeping the pets safe.

Houseplant Care in Winter

Peace Lily grow well in low light.

It’s been a tough couple weeks for my houseplants. Power outages from recent storms made me move my African violet which was just starting to bloom over to a window for more light. Others are staged on tabletops. I know my houseplants clean the air and provide indoor beauty while the landscape outdoors is mostly resting. They are easy to keep healthy if I follow a few tips during the dark days of winter. it’s their time to rest.

A typical houseplant lives in the understory of a tropical rain forest where it gets filtered light. They’re used to warm rain and perfect drainage. We put them in pots inside our homes where they have much different conditions to contend with. Most houseplants will tolerate darker conditions if you adjust your watering to accommodate the slower growth rate.

Water just enough to keep the soil from going totally dry allowing oxygen to move back into the root zone. Let the soil in a 4-6 inch pot dry half an inch down between watering then water with room temperature water. Don’t let the pot sit in a saucer of water or the roots will rot. If your plant is in a larger pot let the soil dry a couple inches between waterings. A moisture meter is very helpful for larger plants.

Move plants into the best light you have. Even a table lamp will provide light for a plant growing underneath. Remove dust with a moist cloth or place the entire plant under lukewarm water in the sink. Dust blocks light from reaching leaves.

Fertilize less often skipping December and January and starting up again with half strength fertilizer in mid-February. Houseplants are essentially dormant in winter needing fertilizer only when active growth resumes.

Don’t re-pot a plant in winter when they are slow to grow new roots. Replant when the growing season resumes in March or April. Choose a pot only two inches bigger than the old pot each time you transplant. Most plants grow happily for years in the same pot and soil with proper fertilizing and watering during the growing season.

Avoid placing plants in cold drafts near high-traffic areas such as a foyer or hallway. Ficus trees are notorious for dropping leaves when exposed to temperature changes.

Sanseveria ( Cast Iron Plant ) grow in very dim locations

If you have medium to low light conditions in your house some of the best upright plants are philodendron, peace lily, Chinese evergreen, cast-iron plant, schefflera, arboricola, ferns and palms. Hanging plants that grow well in low light are heart-shaped philodendron, pothos and grape ivy. Most of these houseplants grow naturally in low light areas of the jungle. Don’t overwater and they’ll be happy.

If you do find insects on your plants, a spray of mild insecticidal soap for houseplants usually does the trick if you do a follow-sup spraying a week later. Horticultural oil works well, too, by smothering insects and their eggs. If you have tiny black gnats flying over the soil you are watering too frequently. They feed on the algae growing on moist soil. Scrape off the surface, spray with insecticidal soap and let the soil dry out.

Magenta – 2023 Pantone Color of the Year

We are all drawn to different colors in a garden. Some of us like soft, pastel shades while others like strong, jewel tones. They are all great in my book. This year Pantone has chosen Magenta as the 2023 Color of the Year and it’s well represented in nature.

This year’s color is inspired by the red of cochineal, one of the most precious dyes” writes the Executive Director of the Pantone Color Institute. Actually it’s the cochineal bug – oval-shaped scale insects – that are scraped off the pads of prickly pear and turned into natural dyes. They have been used to color food, textiles and cosmetics for centuries. And if you were curious as to how many bugs are needed to produce a fifth of a pound of bright magenta carbonic acid the answer is 70,000.

Back in the garden, the color magenta is a warm color and is more stimulating, dynamic and noticeable from afar than a cool hue which tends to be more calming and understated. Warm colors advance visually, cool ones recede. So to make a small garden appear larger use cool blues and lavenders in the back with just a touch of magenta or scarlet, orange or yellow up close for contrast. Do the opposite to make a large space more intimate – position warm colors at the back, cool colors in front.

Cistus purpureas ‘Crimson Spot’

Magenta is an easy color to include in the garden. Common blooming plants like zinnia, echinacea, digitalis, cistus purpureas, rhododendrons, azalea, osteospermum and some roses all have magenta varieties. The foliage and blossoms of several loropetalum like ‘Jazz Hands Pink’ and ‘Purple Majesty’ would all work to add magenta to your garden.

Loropetalum ‘Purple Majesty’

Garden colors aren’t static though. They vary with time of day, the season, the weather and the distance from which we view them. Also color perception varies among people and not all people with normal vision see color the same way. Since color and light are inseparable, white, yellow and pastels seem more vivid in low light. In overcast or fog, soft colors like pink, creamy yellow, pale blue and lavender come alive. As night approaches and the earth is bathed in blues and violets, those colors are the first to fade from view.

So don’t forget white, cream and silver flowers and foliage to brighten up the night garden. White combines nicely with both warm and cool colors so it’s easy to place. It’s an effective peacemaker between colors that would clash if placed side by side. In shady gardens, plants like white bleeding heart, wavy cream-edged hosta, white browallia, white hydrangea, lamium and white calla lily pop at night. Gardens in more sun can plant Holly’s White penstemon, silvery bush morning glory, dichondra Silver Falls, fragrant Iceberg roses white sweet alyssum and Whirling Butterflies gaura.

Plants grow and gardens change over time. Realize that you’re embarking on a journey that may take many years. Don’t be afraid to play with color even if you don’t get it right the first time. Just learn from your mistakes and make adjustments. And have fun getting there.

Have fun with color. don’t be afraid to try new combinations.
