Crape Myrtles Flourish in the Heat

Some plants perform best when the heat is on; Crape Myrtles revel in the sun and heat. They are summer show-offs.  In full bloom this beautiful shrub/tree radiates color, sporting a full head of crinkled, “crepe” like blooms in various shades, and there are more talents to this tree.

Crape myrtles are drought tolerant once established, but that does not mean they want the water turned off.  New trees require even moisture.  

Earlier in the year, Crape Myrtles give another show when the new foliage breaks with a coppery red tone; and as the season progresses, the bark often splits to reveal a spring pink undercoat. In autumn the handsome green foliage of many varieties changes to either red-orange or maroon before dropping to the ground.

It is, however, the mass of summer blooms, which makes Crape Myrtle worth growing. They range in colors from white, pink, lavender, and purple to almost brilliant red. If it’s white you like, ask for Natchez. Pink Velour produces a hot pink flower.

Another choice is the brilliant red crape myrtle called Dynamite. It’s cherry red flowers, crimson buds, and leaves will leave no doubt that it will create an eye-catching display in your garden. As the red flowers age, they will create an explosion of color.

If powdery mildew has been a problem in the past on your crape myrtle, fear no longer! These mildew resistant varieties are available now in good supply. Muskogee has a lavender pink blossom and produces the most brilliant fall colors of scarlet, orange and yellow. Tuscarora is more upright and produces coral-red blooms in huge flower trusses.

For smaller spaces, enjoy some of the smaller crape myrtle bushes and patio trees. Any of these varieties will add an abundance of color to your summertime landscape. We have many Crape Myrtles in a variety of sizes.

Penstemons

Penstemons are easy to care for and beautiful and water-wise. A North American native; these living jewels thrive in the arid west tolerating poor soil as long as it drains well. Amending our heavy clay soil with Gold Rush is an easy fix. Consider adding this showy perennial to your garden this summer.

Penstemons are the perfect size plant for a bed or a border at about 30″ x 30″. The flowers look a bit like foxglove, tubular in shape, running the length of the stem. The colors are vibrant, some with white throats. Color options range from pale pink to red, purple and lavender and from soft pastels to near true blues. We even have California native varieties.

Care is easy. If you tend to neglect to fertilize and keep your watering on the dry side, penstemons will be a welcome garden addition. Removal of spent flower stems ensures continuous bloom from early summer through fall. Most Penstemons are evergreen and prefer full sun.

Tropical Planting

Tropical plants such as Palms, Hibiscus, Lantana, Bougainvillea, Bird of Paradise, Rose of Sharon are a sampling of the plants that will transport you to the tropics – and most are water-wise.

These hot summer lovers will add a splash of color and texture to your landscape, train bougainvilleas up a south or west-facing wall. The warmth of the wall will encourage early bloom and offer some cold protection in the winter.

Hibiscus are stunning in pots. What a great accent for your sunny porch or patio and since they’re in containers they’re easy to move away from winter’s chill.

Rose of Sharon is a hardy hibiscus producing lovely blossoms mid-summer. No cold protection needed.

Lantana comes in trailing and shrub forms and will bloom summer through fall. Bring on the heat for these nonstop blooming sun lovers.

Whatever you are looking for we are here and very happy to help . . . So please come by and let us do just that.

Bougainvilleas

We have gorgeous bougainvilleas to train up a south or west-facing wall that will give you sheets of color all summer long. Choose from a variety of tropical colors. Don’t forget to ask for planting directions as they have sensitive root systems and will need frost protection in winter.

Tropical Hibiscus

Bring shades of Hawaii to your plantings with glossy leaved tropical hibiscus, again in lots of vibrant colors like red, orange and pink. We have these both in bush and patio tree forms, to give instant height to your garden. Plant these in a protected spot in the garden as they require shelter from the frost and wind. Hibiscus love sun and heat. They bloom late spring through the fall.

Rose of Sharon

A deciduous, frost hardy member of the Hibiscus family is the Rose of Sharon. It produces stunning flowers in the summer and makes an excellent single stemmed tree as well as a large shrub.

Cordylines & Phormiums

Add tropical texture with the addition of Cordylines and Phormiums. Both have sword-like leaves but attain different heights. Cordyline is an exceptional plant to use for height and texture in container plantings. Available with bronze/red or green foliage.

Phormiums or New Zealand Flax are big dramatic plants with sword-like leaves. They produce red or yellow flower clusters on stems that reach high above the leaves. Available in foliage colors ranging from purple-red, bronze, purple and variegated with green leaves with a creamy white stripe. Available in varieties with varying heights from 3-9′.

The tropical Hibiscus and Bougainvillea are frost tender but can survive in the Tri-Valley area. They may freeze back to the ground in harsh winters but should re-grow. In sheltered spots or mild winters, they should be fine, but we recommend the use of insulated fleece blankets and bags, plus non-LED type Christmas lights to add a little extra warmth on those cold winter nights. Planting in pots also means that you can move them into a more sheltered position at the end of the season.

Coleus Dazzle in Shade

Coleus is a summer foliage plant for a bright shade or morning sun location that adds an unexpected sparkle to the summer shade garden.  These unusual plants set off neighboring plants with their colorful foliage. Place them among blooming shade plants in your garden for a splash of light and color.

Mint Family

Coleus share a few traits with its distant cousin, mint. They like it on the shady side and have even been known to thrive in a bright window indoors. We consider them annuals; performing well till the first frost. Unlike mint they stay where you plant them and don’t wander off.

Enjoy Coleus combined with impatiens, ipomoea vine (Sweet potato vine), lobelia, nasturtiums, and other shade loving plants.  They are showy when grown in a pots or shade beds.

Care

Feed about every four weeks with Maxsea All Purpose Plant Food to keep foliage fresh looking. Pinch new growth to keep plants compact.

Blooms are best pinched out before showing color (blue). Pinching keeps the plant bushier by promoting branching leaf growth.

Coleus plants need warm temperatures and rich, loose, well-drained soil to flourish.

Flowering Vines Grace Garden Walls with Color

Flowering vines add color, texture and a vertical element to the garden

Growing a vine up a trellis or along the top of a wall, or over an arbor will give a splash of color or screen a view.  Vines provide a cooling effect by reducing the intensity of reflected light, casting a puddle of shade. They are great for creating layers in a garden without using a lot of space. Vines provide a background for other plants and add a contrasting texture. Consider creating a focal point by planting a vine to grow up an obelisk or topiary.

Let vines help set the mood or reinforce your theme, whether you are recreating a bit of Europe, aiming for an English cottage-style garden or drawing inspiration from the tropics.

Shade a patio by covering a pergola with a large vine or grape.  Vines are a versatile set of plants to provide a dynamic, exciting look to your garden.

We love the following short list of great performing vines:

Blooming now

  • Clematis can provide masses of white or shades of purple flowers midsummer through fall.
  • Honeysuckle offers a profuse show of fragrant white blossoms. Good for covering a fence or bank.
  • Climbing Roses make a stunning, colorful cover for arbors or a wall.  Many colorful options abound. Some will reach 12 or more feet and provide a beautiful frame for a country garden.
  • Pink Bower Vine blooms intermittently through the warm months providing a tropical-like look to sunny or part sun areas.

Blooming or fruiting later 

  • Vine Lilac can handle sun or shade and blooms purple in late January/early February when little else is happening.
  • Grapes are fruitful performers whether you plant table grapes or wine grapes or plant a California native, like Rodger’s red to say, “California.”

Recently bloomed

  • Wisteria is a massive, rampant climber best suited for a large patio cover or pergola. Cooke’s Purple will flower intermittently through summer as well as a big splash in March/April.
  • Pink Jasmine is a beautiful and fragrant evergreen climber that is easy to keep to a manageable 10’. It is lovely when placed left and right of an entry arbor.
  • Lady Banks Rose is a thornless yellow or white vine that blooms once a year and has the impressive ability to raise the height of a fence by about 2’, creating a perfect privacy screen. 

Most vines mentioned here can enjoy living with occasional water… especially if you plant in well-prepared soil, and mulch to improve moisture retention.

Zinnias: Sow and Grow

Zinnias make a brilliant addition to the summer flower garden, loved by novice and expert gardeners alike. The pollinators love them too! They bloom effortlessly from summer to frost, and the more you cut, the more they branch and bloom.

Zinnias are native to Mexico and as a frost-sensitive annual appreciate warm weather. They bloom heaviest when daylight is less than 12 hours.

GENERAL SOWING OR TRANSPLANTING

Sow or plant outside now. Zinnias love the warmer weather ahead. The ideal temperature for sowing zinnias and many warm-season annuals is about 70°+. Think of it as sunbathing weather. Or you can get a headstart planting zinnias from starter plants.

We have starts ready to go into the ground now as well as many varieties from seed.

Zinnias thrive in fertile, well-drained soil in full sun (6 hours or more). Improve the soil with Bumper Crop soil conditioner before transplanting. Sow a group of 3 seeds every 8″-12″ apart and ¼” deep, depending on the variety (consult your seed packet). Or plant 4″ or 6-pack starters.

Weeding
Keep zinnias well weeded, so they aren’t competing for water or nutrients. A well-weeded patch of zinnias also has more airflow, which helps avoid fungal disease. Cultivate shallowly, as zinnia roots are close to the soil surface.

Fertilization
Plan on fertilizing with E.B. Stone Organics Rose & Flower Food – It’s slow release, organic and promotes blooms.

Water
Keep zinnias consistently moist but not soggy; allowing the top inch of soil to dry between watering once plants are established. Water the soil, avoiding the foliage to help prevent fungal disease. Mulching zinnias can help to keep down weeds, avoid soil splashing that can spread disease, and also keep the soil more consistently moist.

Special Care
Once they have four sets of leaves, clip or pinch zinnia seedlings back to just above a set of leaves, to encourage them to branch out. Deadheading frequently keeps zinnias blooming because it stops them from producing seeds, encouraging them to begin the bloom cycle again.

HARVESTING
For extended vase life, harvest before the small yellow flowers emerge from between petals.

COMMON PESTS AND DISEASES

Powdery Mildew looks like a white powder on leaves and thrives in humid weather with cool nights. Reduce chances of this disease by keeping leaves dry while watering only in the morning and during the day. Proper spacing of plants will provide good air circulation, too. Do not compost diseased plants; spores may over-winter and re-infect crops the following season.

Checklist for May Gardening

checkbox[1] Protect your cherry crop! Prevent wormy fruit. Start spraying with Captain Jack’s spinosad weekly when fruit begins to change from green to strawberry color.

checkbox[1] Feed roses now and every two weeks for maximum rose production. Use MaxSea plus Kelp Sea Life for the trace elements and minerals.

checkbox[1] Thin apple, plum, apricot and peach crops if too much fruit has set, you’ll get fewer but larger, juicier fruit.

checkbox[1] Ladybugs and praying mantis to the rescue! Control aphids, beetles, scale and leafhoppers naturally.

checkbox[1] Deep-root water trees and shrubs. Never depend on lawn watering to take care of trees and shrubs. The use of soaker hoses helps deliver deep water as well. Your trees and shrubs will thank you for doing this at least monthly through the warmer months.

checkbox[1] Do you have small sucking bugs on your vegetables? Use vegetable safe Bonide All Season Spray Oil.

checkbox[1] Plant 4-inch or larger vegetable plants and save several weeks of growing time. Remember to protect them from hungry snails and slugs with Sluggo Plus or pet safe Sluggo. Both are labeled for organic gardening, both control slugs, Sluggo Plus controls insects too.

checkbox[1] Prevent olive fruit set with Florel Fruit Eliminator. Spray the olive when the tree has just reached full bloom. Olive flowers are tiny, so watch carefully. Full bloom usually occurs in early May. Spray the whole tree thoroughly. We have the names of commercial spray companies that can help too.

checkbox[1] Turflon Esther for Bermuda grass control controls that wiry-stemmed, nuisance weed Bermuda grass. It also works wonders on Oxalis, a yellow clover look-alike.

checkbox[1] The miracle of mulch. As well as looking good, mulching conserves water and suppresses weeds and keeps roots cool. We suggest a mulch layer of 4 inches thick. Don’t mulch right up to the plant trunk or stem. Leave 4 to 6 inches of breathing room.

checkbox[1] Protect the trunks of fruit trees with Go Natural Tree Trunk Paint. Applying this coating to the trunk will reflect heat away from the tender tissue and protect the trees.

checkbox[1] Regular feeding for Citrus. Citrus performs well with monthly light feedings of fertilizer specifically formulated for Citrus. This will ensure that your tree gets a nice even supply of food year-round instead of occasional periods of highs or lows. We recommend Master Nursery Citrus Food, or for a completely organic approach, use E.B. Stone Citrus and Fruit Tree Fertilizer. Make quarterly applications of Iron Sulfate for optimum feeding and greening.

checkbox[1] Prep your roses for the second wave of bloom! Cut back and feed roses as the first set of blooms fade. Feed with Master Nursery Rose and Flower Food. Water and stand back (roses typically rebloom six weeks after pruning and feeding. For special treatment, feed roses with water-soluble Maxsea. It can be sprayed on the leaves and gives the plant a dark glossy appearance.

Hummers & Butterflies

Your garden can be much more than a lovely, serene place for family and friends to gather. It can be a bird and butterfly oasis. Creating this oasis doesn’t take much more than planting the kinds of plants which will attract birds and butterflies.

To help get you started, we’ve listed some of the annuals and perennials that will entice these critters into your garden. Remember that birds need to feel protected before they begin to gather so try centering these plantings near or around groups of established trees and shrubs.

Hummingbirds and Butterflies enjoy many of the same features in your garden. Both enjoy flowers for food, shelter from the weather, and a place to bask in the sun. Water is another essential — a hollow in a rock or a shallow birdbath can provide the needed water and hours of enjoyment to the observer!! Both hummingbirds and butterflies like to fly freely; and will give aerial shows almost hourly!

A well-planned garden with the proper plants and positioning is the secret to luring hummingbirds and butterflies. Even better, it is also practical and attractive…

Lantana

Flowers in reds and yellows provide a nectar source for butterflies.

Phlox

Butterflies and hummingbirds take nectar from the white and purple flowers. Other birds feed on the seeds in the fall.

Zinnias

Zinnia Magellan Salmon

Flowers provide nectar for butterflies while birds eat seeds in autumn and winter. Single flowering varieties are best.

Lavender

Fragrant purple flowers attract butterflies for nectar.

Stonecrop (Sedums)

Butterflies take nectar from the small pink flowers that bloom from August to September.

Sweet William (Dianthus)

Red, white, rosy purple flowers provide nectar for butterflies.

Achillea (Yarrow)

Yarrow is easy to grow and rewarding with sprays of summer flowers, making great butterfly landing pads. Ladybugs are attracted to this plant as well as butterflies. Grows 18″-24″ high.

Buddleia davidii (Butterfly Bush)

Purple Haze

Can reach 9-15 feet. Cut to knee high in November. Reblooms through summer if old blossoms removed. Great for both hummingbirds and butterflies.

Salvia Greggii (Autumn Sage)

This, and in fact, most sages are hummingbird attractants. Blooming for over half the year, Autumn sage is found in shades of red and pink.

Gaura lindheimeri

Can almost bloom its heart out. May remain in bloom 6 or more months. 2-3′ high and wide. Attracts hummers and butterflies.

Hemerocallis (Daylily)

Easy to grow, strap leaves are a nice contrast. Flowers are 2-3′  and attract both hummingbirds and butterflies.

Hydrangeas

Hydrangeas are among gardeners’ favorite blooming shrubs, especially for the summer shade garden.  They are available in a wide variety of colors and types from white, pink, purple, blue and mixed colors. Their flowers are large and range in shapes from pom-pom-like globes to lace bouquets.

The different shades of blue, pink and white reflect the acidity level of the soil – blue or purple in acid soils, pink or purple/red in alkaline mixtures — this allows you to choose the color of your hydrangeas. In our Valley soil, hydrangeas are naturally pink, you can make yours blue by applying Hydra Blue (aluminum sulfate).

Hydrangeas are low maintenance, fast growing and attractive both as single plants or mass planted. The Endless Summer® series have the ability to produce new flowers repeatedly. It is not unusual to see them blooming well into December. Older varieties typically bloom only once per year and need careful pruning.

Choosing The Right Site
All hydrangeas perform best in dappled shade, with evenly moist, well-drained soil. Ideally, a location where they will get minimal morning sun and plenty of afternoon shade. A semi-shady corner set among ferns for color contrast will enhance any yard landscape. The plants have a stocky growth pattern and will reach 3-5 feet in height and width so be sure to choose an area with enough space.

Hydrangeas are “heavy drinkers,” we have found you can cut your watering in half by adding “Soil Moist” polymer granules to your planting mix.

How To Plant Your Hydrangeas Step-by-Step:

  • Prepare a hole approximately twice as wide as the root ball. Then mix the soil from the hole with an equal amount of Acid Planting Mix. Add Master Start Fertilizer (adjust amount for size of plant) and 2 Tbsp. of Soil Moist to the mix.
  • Backfill the hole with this mixture leaving the top of the root ball at ½ inch higher than the surrounding soil.
  • Add mulch around your new plant taking care to leave a 6″ space around the stem.
  • Keep moist in hot weather.
  • Feed monthly from March through September with Master Nursery Camellia Azalea Gardenia Food.

Things You Will Need:

  • Acid Planting Mix
  • Soil Moist
  • Master Start Fertilizer

April 6th is California Poppy Day

eschscholzia

Many people love the brilliant golden blossoms and delicate frilly, fernlike blue-green foliage of the California poppy. The California poppy or Eschscholzia californica — a member of the Papaveraceae or poppy family — is native to California, Baja California and Oregon. It now ranges from Washington to Baja California and throughout California, Nevada, Arizona and New Mexico.

California poppies (Eschsholtzia californica) are native to the Western United States, including California. The poppies have many uses, including harvesting California poppy seeds to plant or taking cut flowers to brighten up your home. The flowers grow in U.S. Department of Agriculture plant hardiness zones 6 to 10 and generally bloom from February through September.

On Dec. 12, 1890, the California State Floral Society voted to select a state flower. The three nominees were Eschscholzia californica, the California poppy; Romneya coulteri, the matilija poppy; and Calochortus, the mariposa lily. After almost 13 years, the California Legislature adopted Eschscholzia californica as the official California state flower on March 2, 1903. Seventy years later, in 1973, the law was amended to designate April 6 of each year as California Poppy Day.

A favorite as an annual springtime ornamental planting, Eschscholzia californica can be a perennial in mild areas or it can be an annual in cooler conditions. It is easy to grow. Just scatter seeds in the fall where you would like them to bloom in the spring. The California poppy loves full sun but appreciates a little afternoon shade. This rugged plant is extremely drought tolerant and rarely needs fertilizing.

Eschscholzia californica was first described by Adelbert von Chamisso, the naturalist on the Russian ship Rurik, captained by Otto von Kotzebue on its scientific expedition to California and the greater Pacific in the mid-1810s. Chamisso named the genus in honor of Johann Friedrich Eschscholtz, his close friend and the expedition’s physician.
