Sweet Peas & Cool Season Veggies

Fall is in the air – sort of. The sun is setting earlier each day but our days are still beautiful. The autumnal equinox on September 23rd marks the beginning of fall when day and night are of approximately equal length. Gardeners living in Minnesota and Maine are thinking about "battening down the hatches" for winter already. Us, we’re just starting our fall planting season. There are so many possibilities for fall and winter edibles as well as colorful flowers, berries and foliage. For the biggest show there’s no better time to plant than early fall.  Let the fun begin.

While most of the summer annuals and perennials will bloom until at least October, there are cool season varieties that come into their own as our nights cool and last through the winter.  Try  colorful combinations of snapdragon, pansies, violas, sweet alyssum, calendula, chrysanthemum paludosum, forget-me-not, Iceland and shirley poppies, ornamental kale and cabbage, primrose, stock or sweet peas.

Who doesn’t  love old-fashioned sweet peas? A small bouquet will perfume a room with a delicious scent. They remind me of my Aunt Ruth who grew them every year and let me pick a bunch each spring whenever I went to visit. There are many new varieties and colors these days but back then her sweet pea vines were covered with the classic mixed colors of violet, blue, pink, peach and white.

Sweet peas have been around for a long time and many different countries claim that they originated there. One story is that a monk, Father Cupani, first harvested them in the wild on an island off Sicily in 1695` and sent the seeds to the Netherlands. In the 1800’s, an Scottish nurseryman named Harry Eckford began hybridizing and introducing larger varieties in a wider range of colors where they became quite a sensation. The most famous and perhaps the most important use of this flower was the extensive genetics studies performed by Gregor Mendel. Since they self-pollinate, their characteristics such as height, color and petal form could easily be tracked. But whether they came from Ceylon- the modern day Sri Lanka, China or Sicily, heirloom sweet peas are as exquisite in the garden and they are in the vase.

I like to plant early blooming types of sweet peas in October or early November. These varieties flower in the shorter days of late winter. Winter Elegance and Early Multiflora are common early flowering types. Also plant some of the more fragrant spring flowering heirlooms and Spencer’s at the same time to extend your harvest time. My very favorite sweet pea with long stems for cutting and an intense fragrance is called April in Paris. Large ruffled blossoms are a soft primrose cream, tinted at the edges in dark lilac that deepens and increases with age. You can’t go wrong no matter what color or style sweet pea you choose. They are all beautiful.

Now that the weather has cooled, plant cool season veggie starts like broccoli, cabbage, cauliflower, chard, lettuce, spinach, brussels sprouts, bok choy, onions and leeks in soil enriched with 4-6" of compost as summer vegetable crops will have used up much of your soil’s nutrients. You can sow seeds of beets, carrots, radishes, spinach, arugula, mustard and peas directly in the ground.

This is also the time to start perennial flowers seeds so that they’ll  be mature enough to bloom next year. Happy Fall.
 

Vegetable Gardening in Spring

April is a month of change in the garden.  The word originates from the Latin aperire which means to open and refers to this month being the season when trees and flowers begin to open. Thanks to abundant rainfall this winter I see trees, shrubs and flowers blooming profusely. They appreciated last season’s rain but this year is the icing on the cake and everything wants a part of it. 

If cool spring weather has kept you from planting your vegetable garden, don’t worry.  As night and soil temperature warm, newly planted starts and seeds will grow quickly. Don’t plan to plant the whole garden at once. Make a drawing so you can leave space for the veggies that like it warmer.

Remember that cool season vegetables include beets, broccoli, cabbage, cauliflower, carrots, kale, lettuce, onions, radish and spinach.  These don’t mind cold soil and chilly weather. Crops that prefer night temps of 55 degrees and over but will tolerated an occasional light frost are tomatoes bell peppers, corn beans, squash, cucumber, muskmelon and pumpkin. Distinctly warm weather, long season crops that need temperatures in the 70’s are watermelon, eggplant and chilies. You can’t rush Mother Nature.

You can raise the temperature of the soil by laying clear plastic (not black ) over the surface. Be prepared to protect plants at night with row covers, hot caps, cardboard boxes or anything that will trap heat during the night until temps are right for your crop.

Rotate the beds when planting your vegetables to avoid a build up of diseases and insects that can survive in the soil or on plant residue.  Don’t plant the same or closely related vegetables where they grew in the last 2-3 years. 

Pay attention to the watering needs of each kind of plant, otherwise you might plant high water use vegetables beside ones that need need less water.   This can not only waste water but can actually harm plants.  A good guidelines is to group plants by how big they get and how fast they grow. The bigger and faster they grow, the more water they’ll use.  Plant heavy water users at one end of the garden, light users at the other. For instance, plant shallow rooted beets, bush beans, carrots, lettuce, spinach, radishes and other greens together as they grow at about the same rate and use similar amounts of water.  Corn, cucumbers, melons, tomatoes and squash combine well as they all grow rapidly and need lots of water.  Another tip is not to mix new (successive) plantings of carrots, lettuce and other crops with existing ones as water use changes as the plants mature. 

Vegetables at maturity that root over 48" deep are tomatoes, watermelon, pumpkin, winter squash, asparagus, sweet potatoes, and artichoke.  When watering wet your soil to this depth to keep them happy.  Moderately deep rooting veggies ( 36"-48" ) are beet, beans, carrots, chard, cucumber, eggplant, muskmelon, peas, pepper, summer squash and turnip Shallow rooting ( 18" – 24" ) veggies include broccoli, cabbage, celery, corn, garlic, lettuce, onion, parsley, potato, radish and spinach.  Water less if your plants aren’t full grown yet. 

Vegetables in containers are a great solution if you don’t have much space in the ground to devote to them. They warm up quicker in the spring, too. Just about anything that grows in the ground can also grow in a pot or half barrel. This includes vegetables, herbs and even small fruit trees.

Small plants like lettuces, spinach, swiss chard and herbs grow nicely in smaller pots near the back door while large edibles like tomatoes, peppers, eggplant, squash, cucumbers and melons need more room like a half barrel or large 7 or 5 gallon pots.

It’s important to use fresh planing mix in your containers each year.  Heavy producers  need fresh nutrients and deplete the soil by the end of the season. Also feed your containers for the best tasting fruit and vegetables and water on a steady basis. Skip a day of watering when larger plants are at their peak and you can lose your crop. There’s no such thing as dry-farmed tomatoes in a container.

Plant something edible. You’ll be glad you did.
 

Warm Spells during the Winter

Everyone’s talking about the wonderful weather we’ve been enjoying the past few weeks. Spring is in the air. Or is it? Whether you like to putter in the garden or be out hiking, the warblers are calling to you. But is it unusual to have warm weather around here in January? Not at all. Just last year before the rains started we had several weeks of Caribbean-like weather. Back in 2009 during the first two weeks of January temps were in the 70’s and low 80’s. Don’t worry. Mother Nature knows how to adjust to changes in the weather- slowing down when it’s really cold and catching up when it’s mild.

Most plants will acclimate to a gradual return to more normal cooler late winter temperatures. We’re lucky here that we don’t get snow ’cause that’s when nature can really deliver a wallop to tender new growth and buds. If winter remains mild plants may bloom a little earlier. Lilacs, apples and grapes, for example,may flower a week earlier. Weeds can really become aggressive and pests and diseases that were held in check by the cold may become more of a problem. Lifestyles of beneficial insects may get out of sinc with the pests they help control.

Plants make the most of warmer weather. Lawns and other groundcovers, for instance, benefit from warm temperatures in winter. Root growth is encouraged in existing areas and young seedlings  planted last fall become established quicker. If temperatures return to winter norms, grasses will "harden off" and be fine in spring.

Fruit trees usually have no problems with a warm streak. A prolonged warm spell could cause low-chill varieties of peaches, plums and cherries to break bud and flower but these conditions are rare.

It’s a similar story for ornamental trees and shrubs. "Most woody plants have evolved to deal with a brief spell of unseasonably warm weather," says Nina Bassuk, woody plant specialist and director of the Urban Horticulture Institute. Buds won’t open during the first warm spell and then get killed by a return to cold temperatures because buds require a period of cold temperatures to break dormancy. Only some may begin to flower prematurely and risk losing those flowers but the long-term health of most plants probably won’t be affected.

Strawberries are oblivious to the weather. Blackberries and some raspberries are another story. Like some fruit trees, their chilling requirements may have already been met, their buds are swelling and they’re ready to take off. A rapid chill could freeze the buds and canes begin to die from the top down. But even if the entire cane dies, healthy new canes will emerge in spring. The early summer berry crop could be lost but fall berries will be fine.

Most bulbs and perennial flowers should come through a warm spell just fine. The buds of these plants are at or below ground level and often protected further by mulch or leaves. Even if temps return for below freezing, late winter cleanup of old stems will get rid of any winter dieback.

Enjoy this hint of spring. It won’t last for long.
 

Planting Cool Season Vegetables

August is a month of transition in the garden. Some plants like dahlias and crape myrtles  are in full glory while others are starting to wind down. If you look closely, dormant flower and leaf buds are just starting to form on lilacs, rhododendrons and camellias. Seems we’re still waiting for summer it’s been so cool but many plants count night time hours and it’s getting darker earlier and earlier.

Time to plant seeds for cool season vegetables. Start seeds of broccoli, cabbage, cauliflower, chard, spinach, lettuce, kale, mustard, brussels sprouts and collards in containers. Fill flats or pots with potting mix and moisten the mix thoroughly before planting. Sow seeds of carrots, onions, beets, peas and radishes directly in the ground after amending soil with compost.

Cool season vegetables grow best and produce the best quality crops when average temperatures are between 55 and 75 degrees although they can tolerated slight frost when mature. The food value of cool season vegetables is usually higher per pound and per square foot than that of warm season vegetables because the edible parts of the plant are the vegetative parts-such as roots, stems, leaves and immature flower parts-rather than the fruits.

Examples include_
root – beet, carrot, parsnip, radish, turnip
stem – asparagus, white potato, onion
leaf – cabbage, celery ( fleshy  petiole ), lettuce, spinach
immature flower – broccoli, cauliflower, artichoke

Marigolds, Vegetable Gardens and Variegated Foliage

Raindrops on roses and clusters of cherries.
Bright copper grasses and ripe, juicy berries.
The fragrance of jasmine on warm summer evenings.
These are a few of my favorite things.

Ruffled begonias to light up the shade.
Orange and pink sunsets just before they fade.
The sight and sound of hummingbird wings. 
These are a few of my favorite things.

Some of my other favorite things include plants with variegated foliage like Abelia Kaleidescope or Confetti. The first sports gold and green leaves as a pretty backdrop for the white bell-shaped flowers that attract hummingbirds with their nearly year-round nectar. Confetti has creamy white variegated leaves that turn maroon in cold weather. Both are showy, compact plants 2-3 ft tall by about 4 ft wide.

Hebe Tricolor is another of my favorite variegated shrubs. This 3 ft beauty has colorful leaves of burgundy, creamy white and green. As an added bonus it blooms with violet flower spikes in summer. Easy to grow in full or half day sun with good drainage and regular water. This evergreen shrub is perfect as an accent or in the mixed border.

I like all Abutilons.You may know them as Flowering Maple or Chinese Lantern. Pink, red, yellow, orange or white flowers-I like them all. Those with variegated foliage always catch my eye, though. Some are strikingly variegated with creamy yellow or white patterns in the leaves. Others look like taxi-cab yellow paint was splattered on their leaves. They bloom continuously throughout the season and are a favorite of hummingbirds.

Out  in the vegetable garden , don’t slack off picking your ripening produce. it’s an easy thing to do with the distraction of summer heat and vacations. Your veggies, on the other hand, want nothing more than to reproduce.
The summer solstice signaled to plants that days are getting shorter and to stop concentrating on new stems and leaves. Instead, shortening days say better get to flowering and fruiting for the season will be ending all too soon.

Pick veggies everyday if need be. Even one zucchini allowed to grow too big and ripe can tell the plant its job is done and seeds are mature enough to ensure next year’s crop.

Your goal as a gardener and picker is never to let that seed form so the plant is tricked into producing  more flowers and fruit in its never-ending quest to reproduce. This is the secret to keeping your plant hard at work for as long as possible. Even if you don’t eat it, pick it anyway and give it away.

Also in the garden the question pops up frequently about marigolds. Do they help with pest control and which type is the best?

Like other members of the daisy family, marigolds provide nectar to beneficial insects, such as syrphid flies, who prey on aphids and other insects that attack garden plants. Parsley and dill flowers are even better but daisy family flowers keep the nectar flowing longer.

Marigold have been shown to have some slight effect in repelling cabbage worms. A variety called Stinking Roger repels flies that bother cows and other domestic animals but I’ve never seen this marigold available around here.

It’s the common that has been shown to control nematodes. You need to plant them thickly as a cover crop and allow them to grow for many weeks to be truly effective.
Gem marigolds are a favorite food of slugs and Japanese beetles and can act as trap plants. On the other hand, they may just attract more of these pests than there would have been otherwise.

So now you have the rest of the story. The bottom line, plant marigolds as they do have some beneficial effects but mostly because they’re pretty.
