Roosevelt Elementary School Centennial Time Garden On a Rainy Olympia Kinda Day





Getting tired

Over the past couple of years I have been finding the odd website here or there that is displaying my landscape plans as their own creations under their own landscape design advertisement page...I have personally contacted over 10 websites with the request that they remove my plans.

The original work is displayed on these links...with my permission of course:

Page 1
Page 2
Page 3
Page 4

It is getting kind of tiring for me to go around emailing these folks and requesting they remove "my work" that they are advertising as their own..."on their sites".

So I will just create this blog post and list their sites for you to look at my work being displayed across the internet

The company listed below is a good example of how the page designer thinks its okay to display another persons work by cropping out the the original title block and watermarked copywrite stamp on it:

http://www.garpiellandscaping.com/our-services/landscape-design


I often have sat and wondered as I wrote out individual emails to the various sites that have my work on them...how do you sleep at night knowing you are displaying someones work as your own? Displaying something that is unique to the hand of the person that created it?

The drawings are not computer generated and not colored by computer...they are hand drawn and rendered by a technique that is unique to me. So my question is if it is my drawing that gets your customers calling you for a landscape design like the one you are displaying...what happens when they ask for the same results and you cannot reproduce them?

One of my biggest concerns when I opened the doors to my business was that what I displayed was my work and when a customer called me...I was able to give them what I displayed and much more...in school there was a course we took which taught us Ethics and Morals in the practice of Landscape Architecture or Landscape Design...and a big part of that was never to plagiarize someones work...and I have stuck by that for the past 10 years.

Anyway, if you are the owner or web designer/master of one of these sites listed...and would like the link removed from this post...remove my designs first and then contact me with your request. This blog post is in no way meant to be slanderous towards you it is just a way to save me the time and effort of composing individual emails with this theme....and it may be a polite way of saying...Get your own designs to display!!!

Small Garden Design Blueprint For Planting A Three Season Small Space Garden


Using intensive planting techniques as well as crop rotation small garden Design can be successfully achieved. Yields are high when plants are closely spaced. By growing early, mid and late season vegetables in the same space, maximum yield is realized from minimum space.

Its amazing how much you can grow in a small space if you plant intensively and continue to plant in the same space as the seasons change.

The following is a basic plan for a compact, easily workable 4-by-4-foot garden. It can yield delicious vegetables during the growing season, and provide color and interest throughout all four seasons. Although this small garden Design is only 4-by-4-feet, it can seem quite large when preparing the soil for the first time.
The garden needs at least six hours of sun a day, including mid-day sun, so choice of site is very important. This is not meant to be a hard-and-fast small garden Design but a guide for planting a high-yield garden. Other vegetables can be substituted for those Designated.

A great space saver is vertical planting. The plan calls for a fence bordering the northern end of the garden. This makes the best use of available space by training plants upward instead of allowing them to sprawl.

Even early in the year, the garden is productive and attractive. Spring flowering bulbs precede vegetables. Bulb planting is done in the fall.

As spring progresses, sugar snap peas climb the fence. Two broccoli plants are surrounded by Johnny jump-ups. Broccoli is the only edible that stays in the garden throughout the growing season. After the central head is cut, smaller heads form on side shoots. Lettuce is attractive in any garden. New Zealand spinach is a good, heat-tolerant substitute for regular spinach. Beets or carrots interplant well with radishes. Radishes grow quickly, ready to eat in about three weeks, and help loosen the soil for the deeper-root vegetables.

As the weather gets hotter, the early cool-season vegetables start to peter out, and are replaced with mid-season vegetables started from seed indoors or bought from a nursery or garden center. The only exception is the pole or runner beans that trellis up the fence, which grow so quickly they do not need to be started ahead of time. Sharing the fence with the beans is a tomato plant. A warm-weather variety of lettuce planted near the beans and tomatoes is slightly shaded from the harsh summer sun by the vining leaves. Nasturtium fit well between the broccoli plants. There is room for an eggplant and a sweet or hot pepper centered with a clump of chives. The front of the warm-season garden is reserved for low-growing herbs and edible flowers. Dwarf marigold and dianthus add color, spice, and even a measure of pest control to the garden.

As the weather begins to cool, the garden undergoes its final transformation. Tomatoes are left, as they will keep producing. I might sneak in a pumpkin of a very small variety along the fence. Chrysanthemums are a traditional autumnal plant.

Although this is a small garden Design, it contains the basics for an attractive landscape that will last several seasons each year. The rewards for growing your own vegetables are great, not only in terms of money saved at the market, but in pride of achievement.

Morris Elementary School Garden McKinleyville California

Signs that Teach

Another great McKinleyville asset that just needs a little love is the Morris Elementary School Garden.  There always seems to be just one parent at a time that takes the project by the reins and takes it as far as one can, which is apparently unsustainable.  Just as in school, in the school garden, there needs to be some structure and there needs to be some literature, including a design.

Morris Elementary School Garden--McKinleyville, California

I would love to see the rosemary consolidated into a well clipped hedge outside of the raised beds and to have the raised beds generally dedicated to growing food with the bed nearest the entrance a mixture of vegetables, herbs and ornamental plantings.  I like display gardens to have at least one element that displays a common, fast growing, preferably edible, inexpensive plant that may be utilized to create garden architecture.

The stockpile of broken concrete could be used to create a small terrace with thyme in between the cracks.  A sign recommending the use of recycled materials for garden paving and citing the ecological benefits of maximizing the use of permeable paving in our environment educates gardeners and garden visitors on one solution to mitigate two common ecological problems, storm water runoff and waste.  Permeable paving may also be achieved utilizing freshly poured concrete by creating regular gaps in the paving for "green grout" a/k/a tough plantings that can be driven or walked over.  These "green grout" strips allow the storm water runoff to be filtered by the plants and soil instead of just running off into storm drains.  Educational signage will give the garden additional structure as well as educate garden visitors and gardeners alike.


A Woolyschoolgarden would be a smart addition to this garden, bringing the garden beyond the chain link fence yet still within the fenced in school yard, making it seem more accessible to parents and kids coming and going to and from school.  It would also be a good educational element, which references vertical gardening as a small space solution and also a solution for gardeners who lack the mobility necessary to garden in low beds.

I would love to see a few fruiting trees espaliered along the south facing school house wall or along some of the chainlink bordering the west side of the garden.  This could be another educational element of the garden, which references the history and techniques of espaliered trees as well as identifying it as a small planting space solution.

Creating a garden with an educational component like signage, utilizing unique gardening techniques, using eco-friendly hardscape elements and drafting a planting plan and garden design will bring the Morris Elementary School Garden to another level.

Delosperma Ice Plants

Succulent plants for full sun and very well drained soils that are typically hardy from zones 6 to 9 ( unless otherwise noted ). The Ice Plants prefer a gravel rather than organic mulch. They are excellent for gravelly rock gardens and on slopes. Very drought tolerant; they are excellent groundcovers for use in xeroscaping in the west. Many of these are also excellent for use in containers as well as trailing over a wall. Also commonly used for the fronts of borders.
Tolerant of deer, drought, heat, fire, hail, high winds and salt. Few are better for holding loose sandy soil in place. Most really dont enjoy wet winter conditions. They are not prone to insect pests or disease.
Many species of Delosperma contain DMT - oddly enough the same substance that causes dreaming in humans and animals.
