Going Native – Top Native Plants for Your Pacific Northwest Garden

Saturday, July 11th, 2009
Woodland Ferns

Native plantings are the best of all worlds. Beautiful, extremely low maintenance, economical, water efficient and with benefits for the environment!
Native plants, once established, require little help to thrive IF properly planned. They will attract native species of bird and butterfly, handle the native weather (like our varying situation here in the Pacific Northwest – drenching rains to a few months of drought ) and require much less prep work since they don’t need fluffy beds of worked soil to do well.

Figuring out which plants are truly native and finding an ethically harvested source for these plants can be daunting for the first time gardener or the busy homeowner.  If you’re not familiar with natives – don’t fret!  Many local landscapers and gardeners have a staff member with expertise in native plantings who can help guide you through the process, from full-service design and installation to a simple consultation for the do-it- yourself gardener.

For the Pacific Northwest garden, here is a quick list of of  native plants for each layer of the garden that are sure to please!

Acer Circinatum

Columbian lily

  • TREES: Acer Circinatum ( Vine Maple) Cornus nuttallii (Pacific Dogwood) Tsuga mertensiana (Mountain Hemlock)
  • SHRUBS: Cornus stolonifera(Redtwig Dogwood) Gaultheria shallon(Salal) Mahonia aquifolium (Oregon Grape) Ribes sanguineum(Pink Winter Currant) Vaccinium ovatum (Evergreen Huckleberry)
  • GROUND COVERS: Cornus canadensis(Bunchberry) Fragaria chiloensis (Beach Strawberry) Asarum caudatum (Wild Ginger) Maianthemum dilatatum (False Lily-of-the-Valley)
  • PERENNIALS, FERNS and GRASSES: Aquilegia formosa (Western Columbine) Blechnum spicant (Deer Fern) Dodecatheon (Shooting Star) Fritillaria camschatcensis (Black Lily) Iris, Pacific Coast (Pacific Coast Iris) Lilium columbianum(Columbian Lily)Smilacina racemosa (False Solomon’s Seal) Trillium ovatum (Wake Robin)

Your yard may offer enough diversity in growing conditions to open up the palette of natives you can plant: A hot dry rockery or well drained slope will be the perfect environment for some, while a low damp spot or shady area is perfect for others.

  • When purchasing container grown plants choose young plants that are not root bound in the pot – a young plant will adapt much more successfully than a large plant or one that is already root bound.
  • Water immediately after planting being sure to saturate the soil – this eases the stress of planting and helps to settle the soil around the root ball, ensuring there are no large air pockets under the plant.
  • Water evenly and steadily the first two summers- don’t inundate them with water, but don’t let them dry out.  During the first two years your natives will be doing mostly root work, growing wide for stability before putting on height and  growing deep to search for water.
  • After two years, assuming they have been planted where the natural conditions suit them, native plants usually don’t need any supplemental watering in the summer.
  • In general native plants need no fertilizer – and in some cases applying fertilizer may cause unnatural bursts of growth resulting in weak, poorly matured plants.
  • Mulching is good, BUT make sure the mulch is not piled up around the base of the plant – burying the crown of the root ball under too much mulch can result in crown rot.

The Top 5 Vegetables for Container Gardening

Friday, June 26th, 2009

These days who isn’t thinking of eating Locally and Organically?  One of the best ways possible to do this is to grow a few vegetables yourself in what’s called a “Container Garden”.

Newly planted pots with feet and irrigation.

Newly planted pots with feet and irrigation.

Container gardening is simply the easiest, cheapest, safest and best way to ensure an actual crop of vegetables you can add to your menu – the satisfaction of a homegrown salad a few times a week  is well worth it. Many Seattle based garden and landscape companies do container planting. They have crews who specialize in the sometimes difficult task of getting heavy pots and the soil to special situation areas, such as terraces and balconies of condos or apartments.

Getting Started: When choosing a place to site your container garden, consider these factors first. Where will the plants get the most hours of full sunlight?  Is there a source of water that is close at hand and easy to use?  And what kind of vegetables do you want to grow?

Installing Pots: For large and deep rooted plants like tomatoes, pole beans or snap peas you want larger deep pots that can take the weight of the plants as they get large and grow up the stakes these climbing and “vining” types of vegetables need.  A big tomato plant can weigh far more than the pot and it’s soil when it is fruiting, so be sure to use big pots for the big plants. Shallow rooted plants, like lettuce, spinach and radish which don’t need full sun all day, can be tucked amongst the bigger pots so the bigger plants will provide the desired dappled light in the middle of summer.  Any type of container will do from a 5 gallon bucket to a beautiful piece of  pottery, but be SURE that there are plenty of drainage holes on the bottom of the pot.  Putting the pot up on “feet” is really best for good drainage and is very helpful for keeping the area cleaner (you can hose under the pots).  Pot feet can be purchased or can be made from anything that will keep the pot a few inches off the ground and stable, such as bricks, flagstone pieces, or blocks of wood.tomato-plants

Soil and fertilizers: You can grow Organic vegetables by making sure a) your container has been fully cleaned and not used for any kind of hazardous material (especially important if it is plastic), b) that you purchase organic potting soil for your containers.  Potting soil is recommended for container planting as the native soil from your yard is usually too heavy for the fast root work annual vegetables need to do in a very short time. Fertilizing throughout the growing season is great for getting a bumper crop but an organic fertilizer must be used. There are many to choose from on the market today and following the directions carefully is key to success. For a purely organic harvest purchase organic seeds to start with.

Top 5 Vegetable Plants (for the Pacific Northwest) Here in the Pacific Northwest we battle cool temperatures and wet environments – many of the  vegetables we would like to grow aren’t fond of this!  However, heat loving plants, like tomato, basil and peppers, can  be grown with great success if the guidelines for soil amounts and sunlight needs are satisfied (and proper watering of course). The top five plants listed here are vegetables we can grow easily here in our cooler, wetter climate.

  1. Lettuce (and all kinds of salad greens) – Our cool weather is perfect for lettuces and they last a lot longer before bolting (going to seed) than they do in many parts of the country.  There are many beautiful and amazing lettuces on the market these days – seeds for Heirloom varieties are easily found at garden stores and nurseries and they are very easy to grow. Lettuce can be grown almost all year round in the Pacific Northwest.
  2. Spinach (also Kale and Kohlrabi) – Since it requires the same weather as lettuce, spinach does fabulously here – right up until it gets over 75 degrees and it sets seed. Fortunately with our long cool springs you can stagger plant both spinach and lettuce (set new seeds every two weeks for April-June and then again in August for a fall crop) and won’t be out of salad greens for months!
  3. Sugar snap peas – The sugar snap pea is the variety you eat “shell and all” and are a staple in most stir-frys. These cool weather plants need a big container and a set up of stakes to climb on as they reach about 4-5 feet as they start to produce pea pods. They are best to eat when still young and the peas inside are just forming.
  4. Broccoli and Cabbage – Also cooler loving weather plants, Broccoli and Cabbage are planted later in the summer, so they will be ready for harvest as the weather cools down in the fall – the warmth of the summer is when they germinate and grow, and the start of the cooler weather makes them “flower”.
  5. Herbs- herbs are the spice of life, and fresh ones can take your dinner to that next level. Pesto lovers of the Pacific Northwest know that you can get a basil to grow in a pot just about anywhere it will get a day’s full of sun and heat.  But, if you are sun challenged then find and plant the varieties that will be okay with some shade.  Herbs are generally sun loving plants, however, chive, oregano, parsley, cilantro and leeks will do fine with some shade during the day.

Special Tip: Drip line irrigation (which can ensure you don’t forget a watering!) installation should be done before any soil is put into the containers.

Creating Beautiful Home Landscapes

Wednesday, May 13th, 2009

Tiny White CottageLandscaping done well makes your home inviting. It draws attention and shows people that you care. What do you do if you think you lack a green thumb? Break the work of landscaping into its components: Design from execution,  front yard from back yard, and  developing  just one spot from overall goals. Write out all your dreams and ideas for your outdoor spaces and begin to prioritize. Beautiful design ideas must be  balanced to fit your use and the overall context of your home naturally. With a little planning and just getting started you will be amazed at what a difference you can make.

What would this look like?

Let’s say you just moved into a home in which the front landscaping is overgrown and looks uncared for. You’d like to create a nice backyard space, but the front is too bad to not make it the priority. Here are some ideas to get you started:

  • Look at the overall architecture of the front of your house. What lines are its best assets? Some houses have an unattractive addition that could benefit from a hedge or larger bushes. Most benefit from landscaping that is kept trimmed, not planted directly against the house and in proportion with the house.
  • How is the front door or front porch framed. As with a picture, the frame shouldn’t get in the way of the art. Landscaping is its own art, but it shouldn’t compete with your entrance.
  • What does the entrance path to your front door look like? Is it something you can accent? Do you need to create one with stones or pavers set into the lawn?

When you have an idea of your planting spots and border areas, it’s time to figure out what to plant. What direction does your front face? Notice what areas get sun and what times of the day. Familiarize yourself with plant choices you like. Look around your own and other neighborhoods. Notice where these are planted. Visit your local nursury. To get started on your design, here is what to consider:

  • A well planted and maintained landscape will use contrast and compliment to make a statement. What can you use in your yard and what should be taken out? Then plan your new plantings.
  • Note these elements of plants you are considering:  Plant size, both height and width, and overall presence such as bushy or thinly foliaged; leaf size, shape, and color; does it lose leaves in winter or keep them; is it flowering or not; is it invasive and spreading or easy to control; how fast does it grow; does it grow best in shade, partial shade, light sun, or full sun; and does it match the climate in which you live in terms of tolerance of freezing, high heat, highly wet or drought conditions.
  • In your design, plan your anchor plants and small plant or flower beds. Placement of larger anchor plants or trees should be decided on their size and look five years down the road or longer. You can use something that will eventually get too big and need to be removed if that time is a decade away, but consider locations that will work longer term. In small plant and flower bed areas you may want small flowering bushes or plants that are perennials, that come back every year. Alternatively the flowers on annuals last as long as five months. Annuals do not come back the following year but give your beds a lot of pop while you have them.
  • As you consider the plant characteristics mentioned above you will alternatively want to both contrast elements and align them. Differing heights, leaf shape, leaf color, and flower color can create a beautiful mosaic, with nuances of texture and shade. Making good decisions as to when to group similar things together is just as important. While differing heights are important you usually want similar sizes together rather than a high-low-high-low pattern. Some plants will not even show up unless they are grouped with the same or similar plant. A dark unusually textured plant might get lost in a random pattern of plants, but create a focal point when paired up. Random variation of colors in flowers can look good, but might look even better when put in a group. The colors certainly make a bolder statement when grouped.
  • If you are hiring a landscaper or gardener to help you, it might be worth it for you to pay them for some design time. An extra hour or two at their installation rates is a good deal for you and they shouldn’t give that time away for free :>}.

Landscape installation: Whether you use a professional or not, you will want to know some landscaping/gardening basics:

Soil:

  • Healthy soil needs to be acheived and maintained. To understand good soil characteristics consider that roots need nutrients, air, water, and room to expand. Soil consists of four basic parts in various ratios: Sand, silt, clay, and humus. The first three are actually rock particles of three size ranges. For trivia buffs,  the Sunset Western Garden Book says, sand ranges from 1/500 to 1/12 inch, silt from 1/12,000 to 1/500th, and clay is smaller than 1/12,000. You needed to know that! Humus is organic material, as in decaying plant matter, and should be distinguished from Hummus, the delicious meal from chick peas. Clay helps provide minerals and helps the plant connect with other nutrients. Too much clay, and your soil doesn’t drain well, depriving your roots of oxygen. Sand helps with drainage, but too much and you lose nutrients and water. Humus provides nutrients but almost more importantly humus is the great universal fixer of most all soil problems. Soils at the extremes of the sand to clay continuum may need the missing component. Most soils will just need humus. You can also send your soil to a lab for testing: http://www.umass.edu/plsoils/soiltest/.

Planting:

  • Even after you have rototilled your planting area and tilled in nitrogen-added-sawdust, compost, or other organic material, the best planting methods have you digging a large, deep hole at the individual plant location. Mix even more organic material here. This gets good stuff deeper than your overall soil improvement campaign. “Large and deep” is relative to the current and future size of your plant.
  • Check again how much room your plant needs to make sure your design acommodates them. You can crowd a little bit for a fuller look.
  • Take plant out of container by pulling or cutting it off. Untangle bound roots. I usually break the root wad into four quadrants balancing how delicate the particular roots are with the desire to set them free. Longer strands of roots can be draped in the hole and your good soil partially filled in before placing the rest of the plant in place and filling in around it. Read particular planting instructions, but generally plant high, press the soil down around outside of plant, add more soil, and then place hands over top of soil near plant and press down firmly. With all soil pressed down, water generously to settle soil.
  • Keep the area well watered for several days. It is better to hold off on fertilizer for a few weeks to let plants get established.

Spring is in the air!

By Doug
Friday, February 13th, 2009

Maybe I should say Spring is on its way! Winter here in the Northwest is certainly acting more like a lion than a lamb. But, it is still a good time to begin to turn our thoughts towards the gardens and flower beds. I chatted with Erin Nausieda, a Horticulturalist and owner of The Natural Option. Her company designs, builds and maintains landscapes. I asked her what I could be doing in my yard in preparation for the advent of Spring. She gave me several good tips and ideas:

  • Repair Stem Damage: Broken hedges and branches should be cut back cleanly to improve appearance and also to prevent disease and insect infestation.
  • Mulching: Provides excellent temperature control to keep flower beds from getting either too hot or too cold. Also helps to control water usage because mulch holds water, especially in the hotter months. Cedar compost is also good for providing nutrients to plants. Bark mulch tends to rob nitrogen from plants and should be avoided.
  • Design and Plan: This is a great time of year to walk around the gardens and flower beds with a creative eye to make a plan for how you want it to look this season, and how you can improve the look from last season. There are lots of books, magazines and online pictures to help with “idea” shopping.
  • Container Gardening: By actually setting plants in their containers in the ground, on the ground, on porches, decks and other structures, you can achieve an artistic look which is easy to change, easy to maintain and provides lots of variety to your garden.
  • Clean-Ups: This is the time to be doing garden cleanup. Get the garden tidied up, rake debris, prune late-flowering shrubs and cut back any spent plants.
  • Rain “Harvesting”: This method of water conservation is becoming very popular. There is also the benefit of rainwater being nitrogen-rich. Harvesting can be done with any container, barrel or with a more elaborate in-ground tank system. This is a renewable resource.
  • Landscaping Updates: Natural rocks make a beautiful retaining wall, patio, water feature or firepit. If you want a truly natural look, you should consider these over concrete pavers and blocks.
  • Water Features: Pondless water features with waterfalls or streams that disappear into rocks (where the water is recirculated back through a pump and to the top of the stream or waterfall) are replacing systems with basins or ponds that tend to grow algae and provide a breeding environment for mosquitoes. There is also the benefit of less water evaporation.
  • Go “Green”: At the beginning of a new season, it is a good time to consider how you might approach gardening with a “greener” awareness. This is a hot topic in our area and there are lots of resources available to help.

Hope these are some helpful tips.  Please comments if you have other ideas.
