Fall Planted Bulbs Reap Big Rewards in the Spring

It’s that that time of year when we see the beginnings of fall color in the trees. There’s a nip in the air in the morning, the squirrels are busy burying acorns and it’s time to buy bulbs that will welcome spring in next year.

Speaking of squirrels, squirrels, mice and moles are observant and crafty. Once they discover newly planted bulbs, they’ll assume it’s food. Just disturbing the earth is a tip off for them. Daffodils and narcissus bulbs are toxic but if they dig them up then leave them exposed with just a nibble taken, so much for any spring flower display. Protect your bulbs with wire baskets or spray them with foul tasting repellent, letting the spray dry before planting. You can also bury the bulbs with ground up egg shells. Another way to foil squirrels is to plant the bulbs deeply, This only works if you have good drainage, however. Next year, if the squirrels start nibbling the foliage as it emerges try spraying it with hot pepper spray.

Long lived Veltheimia or Forest Lily blooms for a long time.

One of the more unusual bulbs I grow in pots is Forest Lily (velthemia bracteata). I got several bulbs over 25 years ago and fortunately divided them a couple years ago to give as gifts. My pots of these spectacular bulbs did not come back after the fire but I was fortunate that one of my friends gave me hers. The bulbs are enormous and bloom for months. The handsome foliage lis thick and wavy, looking somewhat like a succulent but it’s the huge, showy dark pink flower spikes that bloom from February to May that I love. Grow them light shade and allow them to go summer dormant. Velthemia are native to the northern Cape area in South Africa where it grows on rocky slopes along the famous Namaqualand Flower Route.

Another bulb I’ve wanted to grow for a long time is Ixia viridiflora. A friend divided hers a couple years ago and gave me a handful of bulbs. They need to be completely dry in summer and I forgot and watered the pots that I planted them in so alas, I was not able to enjoy this most striking and unusual bulb but I want to try again this fall. Few plants can beat it for sheer brilliance of flower. Each flower is a brilliant turquoise green with a purple-black eye in the middle. The dark eye is caused by the deep blue sap of the cells of the upper epidermis. The green color is due to the effects of light being refracted from the cell wall and granules embedded in the pale blue cell sap.

What about bulbs in the shade? Bulbs that will bloom in light shade are crocus, scilla, tulips, grape hyacinth, leucojum, snowdrops, chionodoxa and lily of the valley. Many from the daffodil clan, including jonquils and narcissus will grow, bloom and naturalize year after year under tree canopies or other lightly shaded areas.

Whatever you bulbs you choose to try this fall, you will be happy you planted some bulbs come spring. And to help them bloom again the following year fertilize them at the time of planting with bulb food or bone meal worked into the soil a couple inches at the bottom of the hole. Mature bulbs respond to an early spring feeding with the same fertilizer.

Ornamental Grasses for Every Garden

Pheasant Tail grass is carefree and long lived.

One of the most dramatic sights in a garden is an ornamental grass backlit by late afternoon sun. They seem to come alive as their tawny flowers spikes glow and sway in the breeze. Their gentle movement and soft whispering sounds can bring your garden to life as few other plants do.

Most grasses require little care, minimal fertilizer, only occasional grooming and just enough water to meet their needs. Diseases and insect pests are rarely found on grasses They have succeeded because of their adaptability and have evolved to suit almost every environment and climate on earth. True grasses generally have extensive root systems which help control erosion. A garden just isn’t complete without the architectural qualities they provide.

There’s an ornamental grass for every type of garden. Whether you are striving to create the perfect perennial border or have a hot dry slope, grasses can work in harmony wherever you place them. There are some that are made for the shade, some that are perfect additions to a small water feature and many that are invaluable in container gardening.

Grasses are distinguished from other plant families by their growth habit. They grow upward from the base of a leaf or shoot and can regrow from the crown when cut back. There are other grasslike plants that resemble grasses in their growth habits and are often some of the best companions for interplanting with grasses. These include New Zealand flax, carex family sedges, libertia, chondropetalum, kangaroo paw, lomandra, dianella, cordyline and liriope to name just a few.

Mendocino Reed Grass

Are sections of your garden hot and dry? Grasses are survivors and are good choices for sunny spots that get little irrigation. Good drainage is a must for these plants so amend the soil with plenty of organic matter before planting. Combine drought tolerant grasses like Mendocino Reed Grass (pennisetum foliosa) with companion plants and a few accent rocks to complete your dry theme. Good combinations for these areas are Pheasant Tail Grass with the sky blue flowers of Russian sage. If you like blue foliage, try Elijah Blue fescue grass with Amazing Red flax for a show stopping combination.

If you are trying to create a focal point or destination in your garden and think the texture. light and movement of a grass would be perfect, look to the taller varieties. A personal favorite is Stipa gigantea or Giant Feather Grass. They take drought conditions once established but also will grow with regular garden watering. The beautiful flower spikes are good in dried arrangements. Giant Feather grass looks great with the purple flowers of penstemon ‘Midnight’.

There’s a reason old favorites like Karl Foerster feather reed grass is so popular in landscapes. It doesn’t get too tall or overpowering in the smaller garden and its upright habit is neat and tidy. Pheasant Tail grass is another popular grass that is carefree and long-lived. It grows to only 3 by 3 feet, is not fussy about soil and looks good anywhere you plant it. It combines beautifully with the sky blue flowers of Russian sage and is extremely drought tolerant once established.

Caring for grasses is easy. As a rule of thumb, if it browns in winter then cut it back before new growth starts. If it’s evergreen by nature just clean up outside leaves. Most like well drained soil and are tolerant of a wide range of garden conditions. You shouldn’t fertilize heavily because an excess of nitrogen can lead to lush, soft growth that tends to flop. Mulching with 2″ of compost yearly will keep the soil and your plants in good shape. Water grasses regularly during their first year to help get a good root system established. Even grasses that are normally touted as drought-tolerant require a season or two to become fully established.

These are just a few of the places where grasses can enhance and add beauty to your garden. Fall is the perfect time to plant a new one.

California Natives for Fall Planting

Matilija poppy – a good low water native shrub to plant this fall

Beautiful beginning-of-fall weather is here and you may be thinking what plants you might to add to your garden this fall planting season. California native plants are well suited to planting at this time of year, acclimating to their new homes without much stress. Here are some ideas to get you started.

By planting from mid-September through mid-November, roots of all plants have a chance to grow during fall and most of the winter without having to supply nourishment to the leafy portion of the plant. Roots of deciduous plants still grow even after plants drop their foliage as long as the ground temperature is above 50 degrees. Cooler day and night temperatures slowly harden off the top of the plant to prepare for the cold days of winter.

Another reason that fall is the “no-fail” planting season is because plants put in the ground in fall need less water to establish. The plants themselves use less water since photosynthesis is slowed by shorter days even if it’s occasionally warm. Evaporation rates slow down also during fall so moisture in the soil lasts longer as well. Sometimes we get lucky with fall and winter rains perfectly spaced so the ground never completely dries out. Unfortunately there is a 66% chance of a La Nina winter but let’s hope we get more rain than last season.

Plants that thrive in dry, shady spots benefit especially from fall planting as they need established root systems before next years dry season. Dry shade sometimes occurs in places beyond the reach of the hose but also under native oaks. To protect the health of native oaks, it’s a requirement that plants underneath thrive with little or no summer irrigation.

King Edward VII flowering currant – A California native show-stopper shrub for erosion control

Plants of proven success under these conditions include native currants and gooseberry. Red flowering currant is a show stopper capable of controlling erosion. In the spring, the long, flower clusters of this deciduous shrub will dominate your garden. There are many selections to choose from so if the huge white flowers appeal to you ‘White Icicle’ will be beautiful in your landscape. ‘Barrie Coate’ and ‘King Edward VII’ have spectacular deep red flower clusters and ‘’Spring Showers’’ has 8″ long pink ones. Grow in full sun to partial shade. This California native requires little water once established and is a valuable nectar source for hummingbirds.

Some other good California native shrubs for erosion control are western redbud, mountain mahogany, western mock orange, lemonade berry, toyon, snowberry, matilija poppy and western elderberry. Rbes viburnifolium, creeping mahonia, snowberry, ceanothus maritimus and ‘Anchor Bay’s are good groundcover selections.

Smaller natives that put down deep roots are yarrow, coast aster, California fuchsia, wild grape, mimulus, buckwheat, wild rose, sage and salvia.

Bush poppy

Bush poppy (dendromecon rigid) is another native found right here in our area and needs no irrigation at all once established. Beautiful bright yellow, poppy-like flowers cover the plant in spring. They can be propagated from cuttings taken in summer and are pest and disease free.

Remember when setting plants on a steep slope to arrange them in staggered rows. Make an individual terrace for each plant and create a basin or low spot behind each one (not around the stem) to catch water. Set the crowns of the plants high so they won’t become saturated and rot after watering and make sure mulch does not build up around the stem.
