Spider Mites

Leave a comment

That’s a good question
If you notice the leaves on some of your plants appear stippled or flecked with pale dots and have fine webbing, especially on the undersides, you have a spider mite infestation. These pests thrive during dry weather and their populations can get out of hand by August.

Mites puncture plant cells with their mouthparts, then suck the plant fluid. The tiny areas of leaf tissue that have been killed appear as tiny dots on the the leaves. Mites often go unnoticed because they are tiny and natural controls such as weather and predators frequently keep their populations low. Severe infestations often result because these natural controls have been disrupted by pesticides and excessive dust.

Control spider mites on fruit and nut trees, azalea, fuchsia, maples and rose by regular, forceful spraying of plants with water to rinse dust and dirt off both sides of leaves. If you do have to spray to control an outbreak use insecticidal soap or a light spray oil. Sulfur is effective in reducing populations of some spider mites but this dust can disrupt beneficial predaceous mites.

Avoid using broad-spectrum pesticides which disrupt biological controls. When applied for other pests during hot weather, these can cause dramatic outbreaks of mites within just a few days even though their label may say they control mites.

Although a young or weak plant may not survive a severe spider mite infestation, it is not usually fatal to a vigorously growing tree or plant. The best defense is a good offense – periodically spray your plants with water in the morning to keep them clean and dust free.

Planting Cool Season Vegetables

Leave a comment

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

Bouquets from Your own Garden

Leave a comment

A gardener’s life:  water, prune, plant, rake, weed, stake. Repeat as necessary. Then smell the roses, harvest the vegetables and It’s great to be out in the garden among your beautiful plants. Reward yourself and bring the outside in.

Have you ever seen the spectacular arrangements made weekly for the mansion at Filoli Gardens in Woodside? They are truly breathtaking, composed of whatever plants and flowers happen to catch the eye of the harvester. You can have this too for your own dining room table, kitchen, bedroom or bath.

Until about 100 years ago, one of the most important areas of any large garden was the cutting garden, where flowers were harvested like a crop and taken inside for display. Today our lifestyles and tastes are reflected in bouquets that are more casual. The bouquets you make from garden grown flowers, interesting foliage branches, grasses, vines and even herbs always seem to have more personality and cottage garden softness than ones bought from the store.

While just about any plant material that strikes your fancy will work in a mixed bouquet there are four types of plant forms that naturally look good together:  Spires for height and architectural properties ( liatris, snapdragon,gladiola, salvia, Bells-of-Ireland),  Round for focus ( roses, dahlias, long-stemmed marigolds, peonies), lacy for fillers ( ferns, baby’s breath, dill ) , foliage ( abelia, breath of heaven, Calif. bay ), and ornamental grasses.

Here are some unsung beauties to grow and add to your arrangements.
* Love-lies-bleeding ( Amaranthus caudatus ) Long, to 18", pendulous ropes of red flower clusters. Handsome mixed with bold companions like zinnias and sunflowers. Good dried flower.
* Bells-of-Ireland ( Moluccela laevis ) Showy, apple-green flower spikes, long lasting in either fresh or dried arrangements.
* Transvaal daisy ( Gebera jamesonii) Perennial, long-stemmed varieties bloom nearly year round with peaks in early summer and late fall. Prized cut flower. Split stem end, dip in boiling water and stand in deep water with sugar for long vase life.
* Lisianthus. Perennial grown as an annual. Flowers resemble roses in shade of purplish-blue, pink, and white. Blooms all summer on strong stalks.
*Pink muhly grass ( Muhlenbergia capillaris) airy plumes of feathery, deep rosy-pink flowers on tall stems. Drought tolerant.

There are so many plants to use in bouquets. Don’t forget grapes and other vines, herbs, woody trees branches and shrub foliage look great, too

The best time to cut is early in the morning. Cut non-woody stems on a slant for maximum water absorption. Cut woody stems straight across and smash the ends. Plunge immediately in a bucket of tepid water. Indoors, fill the kitchen sink with cool water and recut each stem under water so an air bubble doesn’t keep the water from being absorbed.

Then pull off any foliage or flowers that will be below the water level in the vase. Fill the vase with lukewarm water. You can add cut flower food but I find that changing the water every two days and making sure no foliage is under water works just as well.

If a plant isn’t working our or is spent in your arrangement just remove it. The main thing is to have a garden that you love both inside and out.

Marigolds, Vegetable Gardens and Variegated Foliage

Leave a comment

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.

Progating Heirloom Veggies, Fruit Trees & Christmas trees

Leave a comment

‘Tis the season. No, not that season but the time to propagate and increase the number or your plants. Maybe you want to save seed from your heirloom vegetables or start more shrubs inexpensively. How about getting more fruit trees or even trying your hand at starting your own Christmas tree?

Let’s start with saving seed. When your vegetables start to produce this summer, you may want to save some of the seed of plants that produced the best-tasting, earliest ripening fruits. These will be strains that are particularly adapted to our climate.

You can only save seed from open-pollinated varieties– those vegetables that are bee or wind pollinated. All . You cannot save seed from F1 hybrids as their unique traits, such as specific disease resistance and early maturity, are uniform only in the first generation of seed. Seed saved from hybrids they will not come true when replanted.

Hybrids have their place in the garden especially if you have a very short or cool season, not many hours of sunlight as you’d like or a serious nematode problem.

If you enjoy saving seed, it’s fun to identify your best plants to save and use every season. Become a backyard breeder and develop your own unique cultivars for your garden.

Propagating fruit trees involves more than saving seed because 99% of all seedling trees bear fruit inferior to that produced by the parent. It may be the same species but it is unlike that of the parent in flavor, color and date of ripening. To obtain a true-to-type fruit tree that is a clone of the parent tree, it is necessary to graft or bud on a desired rootstock. The graft wood, called a scion, should be collected in January so you have lots of time to ask the neighbor for a small, pencil-thin branch of their peach tree to add to yours or to get a branch grafted onto your tree that would pollinate your cherry, apple or whatever you might need. You can even graft different trees together if they are compatible such as an apricot on plum rootstock or almond on peach.

Mid-July to early September is the best time to propagate broadleaf evergreen shrubs. The growth flush is complete, the wood is firm and the leaves have matured. Using cuttings 3-6" long and rooting hormone they will root in 4-6 weeks. Ceanothus, manzanita and camellia are just a few of the shrubs that can be rooted this way.

And what about those visions of starting your own Christmas tree? It’s difficult to start a tree from a cuttings unless it’s a very fresh cut tree and the cutting is taken from currents seasons growth near the base of the plant. Most evergreen trees used for cut Christmas trees start their lives from seeds. These seedlings grow 1-2 ft in a year or two. After transplanting, they become 6 footers in 5-8 years. So if you are patient you can grow your own from one of those started seedlings. Doug fir, Scotch pine and Noble fir are popular varieties.

There are so many types of plants and methods to increase your collection. Perennials, houseplants, berries and grapes all lend themselves to propagation. I f you have a favorite plant or just want to increase your plants inexpensively there’s a way to do it.
