Fall Gardening Tips

Leave a comment

Someone asked me the other day  " What’s good to plant this time of year "?  It’s a good question.  I often receive emails asking for advice or ideas for solving all sorts of gardening problems and landscaping situations.  You may be wondering about some of these yourself.  Hopefully, they will solve your problem, too.

What is good to plant at this time of year ?
Fall is a good time to plant just about anything in this area. If you want an ornamental tree with spring flowers or a shade tree to keep the house cool in the summer, now is the time to plant.  The ground is moist now so digging is much easier and the warm soil will encourage root growth.  Shrubs of all types as well as perennials settle in nicely when planted in October and November.  Don’t have color in your garden from fall foliage like you see in other yards when driving around?  Take advantage of fall sales at local nurseries.  There are tons of plants now in fall color to choose from.

Why do trees turn colors in the fall?
The shorter days and cooler temperatures of autumn cause trees to switch into energy-storage mode, at which point their leaves stop producing chlorophyll.  For the few weeks before the leave fall to the ground, they are colored only by their natural pigments.  It’s these colors – red and purple anthocyanins,  yellow  and orange carotenoids –  that make fall foliage  so glorious. Some years the show is more dramatic than others.  The best conditions for intense leaf color to develop are dry sunny days followed by cool ( but not freezing ) nights. 
A warm, wet autumn will almost surely result in less-than-spectacular foliage because the process of chlorophyll loss will be less consistent.   Freezing temperature, meanwhile can cause leaves to drop suddenly, denying the opportunity to enter their slow, colorful dormancy. 
 

 

When do we usually get the first frost here? 
I have kept a weather calendar since 1992 and based on my records there was a light frost on Oct. 29, 2002.  I’ve seen an early hard frost as early as November 7th but more commonly, frost comes later in November.   In "97-’99 frost didn’t occur until the first week of December.  Be prepared.

How long can I leave my houseplants outside? 
Halloween is a good time to bring them in.  We don’t have the heater on full blast usually this early so they don’t suffer  shock going from a cold environment to a heated one.  Be sure to inspect them for insect pests and wash them off before bringing them inside. I have to confess, I roll the dice and leave spider plants, wandering jew, Hawaiian shefflera and creeping charleys outside under the overhang. I’ve been pretty lucky most winters.

Some winters my tree ferns and bananas suffer.  How can I protect them if we have a really cold spell?  
Many subtropical plants benefit from extra mulch to help them survive a hard frost.  People from the east coast know all about this.  Just be sure to take it away from the stem or trunk come spring or the mulch can cause rotting.

How to Plant a Vignette in your Garden

Leave a comment

Most people want to do the right thing, they just don’t always know what it is- in the garden, anyway. Often when I visit a garden to help with the design, I find lots of great plants scattered about that just need to find the right spot to call home and something to tie them together.

We all do it – over the years buying plants we just have to have with no plan of where they might be used effectively. The garden becomes a collection of mismatched plants and that dramatic border you’ve envisioned just don’t come together.

Where to begin? Picture sections of the garden as separate scenes composed of small groups of plants that look good together because of their complementary and contrasting features.

Start with a strong foliage plant, then add other plants with interesting textures, forms and colors to complete the scene. Don’t simply alternate textures because that could make the garden look too controlled and predictable. Sometimes repeating a bold, course texture makes the planting restful.

Select the first plant in a vignette for its foliage. Because it serves as the main plant, it has to have leaves that look clean year round or from the time they emerge in spring until fall. Avoid plants that become discolored or tattered as the season progresses from weather, disease or pests. You can discover reliable foliage plants by observing other gardens, especially in late summer.

Examples of strong anchor foliage plants for shade include Japanese maple, hydrangeas, dogwood, pieris japonica, camellia, aucuba, rhododendron, ribes sanguineum and viburnum,. Good plants to anchor a sunny garden vignette would be butterfly bush, a tall grass like miscanthus sinensis Morning Light, ceanothus Concha, rockrose, western redbud, bush anemone Japanese barberry and lavatera.

Select supporting plants to balance the main plant in your grouping. Vary the shapes of these secondary plants to create interesting compositions. Too many plant like iris, daylilies or liriope with swordlike leaves, for instance,  would create vertical chaos. You can use one but no more than two plants to add vertical emphasis. Also using more fine-textured plants than course, large-leaved plants seems to work better. Shady medium-sized plants might include hardy geraniums, hosta, carex Evergold, ligularia, coral bells, Pacific coast iris and western sword fern. Good supporting plants for sun include salvia, penstemon, rudbeckia, yarrow, artemisia, eriogonum, blue oat grass and society garlic.

Groundcovers finish a vignette. Look for color cues from your first foliage plant and choose a low grower that complements it. Color can connect plants that differ greatly in form and color. Think of groundcovers as carpeting for your garden. Golden creeping Jenny and lamium Pink Pewter are good choices for a shady area while elfin thyme and dymondia would tie together a group in the sun.

Don’t be afraid to move a plant that is not working where its growing now. Make a note in your journal reminding yourself to transplant it sometime in the fall. Gardening is a dynamic and fluid process. Enjoy piecing  together pieces of the puzzle.

Permaculture and You

Leave a comment

We all want to do the right thing for the environment by reducing our carbon footprint and becoming good stewards of the land. We want to build our landscapes with green products and incorporate sustainable practices in the garden. A good way to do this is to create gardens that offer food and beauty for people while providing habitat and other benefits for the rest of nature.

Permaculture is the fancy name for this approach to garden design. When you garden using organic fertilizers and organic pesticides ( when necessary ) you reduce pollution in the environment. When you plant edibles like beautiful fruits, vegetables and herbs in your yard, you create a more natural landscape that takes better care of itself while yielding a plentiful harvest of plants for food.

You can put these ideas to work in your own garden by using water more efficiently and carefully selecting and siting plants. Deep rooted trees like fig, mulberry, peach and plum help break up heavy soil and shade the plants beneath them. Planting drought tolerant trees creates shade which in turn slows the evaporation of moisture from soil and prevents erosion.

Group plants with similar water needs. Grow thirsty plants in the lowest areas of your garden where more water collects. You might install a rain garden in an areas like this. A rain garden is simply a planted depression designed to absorb run-off from areas like driveways, walkways, roofs and compacted lawn ares. The rain garden acts to replenish ground beds while preventing water from running into storm sewers, streams and creeks.

Plant dry climate plants like lavender, rosemary and sage in open, sunny areas and drought tolerant ground covers like oregano and thyme to shade the soil and conserve moisture. Use less turf grass and more walkable ground covers where possible.

Place hardy perennials like artichoke, butterfly bush and rhubarb under tree canopies to conserve moisture. In general, use deep-rooted, low maintenance perennials that provide food and also shade for plants underneath.

For food, plant fruit trees, berries, nuts, herbs and vegetables. To create habitat, plant fennel, spearmint and yarrow for beneficial insects; butterfly bush and sage for pollinators such as bees and hummingbirds; ceanothus and other native shrubs and trees for birds and other wildlife.

To , plant deep rooted plants to break up heavy soils and add organic matter. You can plant rhubarb, bear’s breech or other large leaf plants for a living mulch. Using wood based mulch on garden beds helps contain moisture in the soil, too.  To provide soil with nitrogen, plant ceanothus, clover, legumes like beans, and peas and lupine. To supply minerals as compost or mulch plant chives, comfrey, garlic and white yarrow.

Sustainable landscapes do not have to look like a weed patch. With a little planning your garden can be beautiful and productive.

Veggies & Fruit trees for Small Spaces

Leave a comment

You know that growing your own fruit and vegetables can supply your family with fresh tasting and nutritious food. But what if you don’t have much space for a big garden or an orchard of fruit trees. Now days there are lots of available for smaller yards and containers. Here are some good ones to try.

Tomatoes are always popular to grow whether in the ground or in pots. Bush types don’t grow as large as vines. If you like large size tomatoes, plant Bush Beefsteak and you’ll be harvesting clusters of delicious 8 oz. tomatoes in just 62 days. A half wine barrel can house a taller tomato like the ever popular Sungold . Small gold-orange cherry tomatoes ripen early and are oh-so-sweet. You’ll plant these every year after you’ve tasted one.

Zucchini lovers might try the semi-vining Raven variety which won’t take up as much space as a traditional type. These plants bear black-green, white flesh fruit with a mild sweet flavor and are very tender. If you have a little space to spare grow the round French heirloom squash, Ronde de Nice. Jade colored zucchini produce over a long period. Harvest the fruit when they reach golf ball up to baseball size. They are sublime grilled or try them stuffed. They are unique in the garden and wonderful in cuisine.  A tip to encourage pollination when squash or melons bloom is to pinch off leaves covering the blossoms in order to give pollinators a clear path to the flowers.

Herbs make good additions to the smaller garden, too. They can be kept compact with frequent pinching as you harvest sprigs for cooking. They also attract beneficial insects to the garden. Oregano, chamomile and fennel are good insectary herbs.

Dwarf fruit trees can also find a place in the smaller garden. They can be grown in large pots or half barrels on the deck, too. Dwarf Garden Delicious apple is self-fertile and bears at a young age. Greenish-yellow skinned fruit with attractive red color ripens in late September into October. They grow to 8-10 feet at maturity.

Compact Stella cherry is also self fertile and is a good pollinizer for all sweet cherries. The fruit is large, dark red or nearly black. Firm, sweet, dark red flesh has good flavor and texture. Stella cherries grow 10-12 feet tall and bear at a young age.

If it’s almonds you crave for your patio or mini-orchard, plant a Dwarf Garden Prince almond. This compact 10-12 ft tree blooms mid-season with beautiful pale pink blossoms. Dense attractive foliage and good quality sweet almonds make this tree a nice addition to any garden.

A patio-sized peach for smaller yards is the Dwarf Southern Flame.  Large, yellow, aromatic freestone peaches are firm, crisp and melt in your mouth. Tree height is just 5 ft and the fruit ripens early to mid July.

Don’t let lack of space stop you from enjoying fresh fruits and vegetables this year.

Citrus in the Garden

Leave a comment

There’s always so much to do in the garden in early spring.  It can be overwhelming deciding what’s important and what can wait. This is how I tackle my garden to spruce things up in a hurry.

First, I decide what problems stand out and choose what to do based on which areas will be the most noticeable. Which improvements will have the most impact?

Focus your attention where family and friends gather- the patio, a shady spot if it’s hot or a sunny area if it’s cool in your garden. Clean up what catches your eye like dead limbs, tall weeds or clutter. Sweeping the deck or patio will make the whole garden look better.

Flowers attract the most attention. Focus on the beds closest to gathering spots and those places you see outside the windows.  Enhance what you have. Blooming or bright foliage plants can fill in gaps in beds.

Perk up your entry with new plants. Group several containers filled with plants you love.  The bigger the plant you use, the more immediate the effect. Combine shades of all one color like blue, purple or red for a more dramatic look.

What else can you do to spice up your landscape?  Plant a dwarf citrus. They grow to only 8 feet so fit into small spaces. Plant in a spot that gets full sun and has well drained soil. Citrus are slow growing and do great in containers, too.

A favorite lemon variety is Improved Meyer. It a actually a cross between a lemon and an orange and tastes slightly sweeter than a true lemon  such as the Eureka. The fruit is very juicy and holds well on the tree, increasing the sweetness.

If your’e looking for an ornamental specimen for a patio container, consider a Nagami kumquat. Small reddish-orange fruit hang on the tree nearly year round and you eat them whole-peel and all. This small symmetrical tree is Japan’s most popular kumquat.

Another very attractive citrus is the which is also known as the Clementine. Its weeping form, dense, dark foliage and fruit that is held toward the outside make this a very showy specimen either in a container or in the ground. Sweet and juicy fruit hold on the tree for several months. This is the variety you see in the market from December to May. Wouldn’t  it be great to have one in your garden?

New Plants for the Garden

Leave a comment

Every season new varieties of colorful flowering annuals and perennials are introduced by hybridizers. These new plants are field tested and bred for better performance, disease and insect resistance, flower size, color and heat tolerance.  Where does this happen?  What goes into that gorgeous vivid red geranium you see on the bench at the nursery?

Over 30 breeders of flower seeds and perennial starts each spring showcase their new varieties in trials held throughout the state.  Professional growers visit the trials to choose which new varieties they will grow this year and offer to local nurseries and garden centers.  Goldsmith Seeds in Gilroy is one of the locations that hosts the colorful spectacle.

Fragrant, wisteria-covered arbors shade paths that wind throughout the landscaped grounds . The grounds are open to the public to enjoy throughout the summer.  Also on site are the greenhouses where breeders work on creating new and better flower varieties.  It was interesting to see several acres planted with fava beans as a cover crop. Soon the fields of this flowering legume will be cut down and tilled into the soil to add nitrogen. Legumes attract soil dwelling bacteria that attach to the plant’s roots and pull atmospheric nitrogen out of the air and soil, storing it on the roots as nodules.  When the plant is cut down and chopped up to decompose that nitrogen remains in the soil to feed new plants. After a few weeks of decomposition the energized soil will be ready for planting test flowers that Goldsmith seeds will further evaluate.

All of the seeds are actually grown in greenhouses in Holland and Guatemala. Cool season flowers like primroses, cyclamen, violas and pansies are produced mainly in Holland while warm season flowers like dahlias, geraniums, gazanias, and verbenas are grown at different elevations in Guatemala. I learned Goldsmith Seeds has been developing and growing seed in Guatemala for 40 years.

What new cultivars really impressed me at the trials?  There’s a new geranium that combines the best features of ivy and zonal geraniums. I liked the amazing color of Calliope Dark Red but all the colors were show stoppers. They would be perfect for baskets or beds in full sun or part shade. And you should see all the colors that calibrachoa now comes in-light blue, dark blue, deep yellow, peach, orange, even white with rose veins. These have now been bred to bloom earlier in the season which is why you’re seeing them in nurseries now.  There were many fragrant flowers like . I always looks forward to them when they arrive at the nursery. 

Try something new in your garden this year. There are so many good choices.
