History of the Brilliant Container Garden...

 "Container gardens are perhaps the origin of landscape architecture itself!" says Stephen T. Swafford, BLA (STS). These potted delights can be traced back to 2100 B.C. Terra-cotta remains were uncovered outside the Minoan palace in Crete. The much celebrated Queen Nefertiti of ancient Egypt grew palms, pomegranates and vines in large planters in the garden of her temple to the Sun God. The Romans, clever as they were, built elegant and elaborate gardens where containers were filled with all sorts of ornamental plants. (Even today, Rome continues this legacy of lushly planted pots and hanging baskets.) Next, the early followers of Islam built gardens as a place of inspiration honoring the afterlife. These gardens were architecturally accented with containers, placed in geometric patterns and filled with all sorts of fruit trees and roses. The Spanish-Moors are credited with not only dwarfing varieties of fruit trees, but also even more importantly, arranging container gardens to block northern winds (which tend to be strong and cool). Those stylish Europeans, with their travels to the Far East, and to the Americas, refined their horticultural interests to include exotic plant materials which were brought home and planted in containers. They, too used geometry as their basis for arrangement in massive gardens during the Italian Renaissance period. In 17th Century France the world's first Landscape Architect, Andre Le Notre, used 250,000 containers to adorn Versailles. He planted a grove of Orange trees which were on rollers, and moved in and out of the green houses for protection. The French loved splendid color and used container gardens to feature an ever changing crop of seasonal color. The English, being quite individualistic, choose a more natural landscape, but they too used containers but more as accents.
Today, planting pots are used all over the world for a variety of reasons...mainly for their beauty, but also for function. Container gardens may be placed architecturally to screen or create privacy, block the hot sun and/or cold winds, and contain plants that have invasive root structures, such as Bamboo. "Planting containers are real problem solvers.. even in areas with poor soil, one can add a planting pot filled with rich soil and grow roses in the desert. I love using containers in our designs, they not only are ornaments in the garden, but they are real problem solvers!" --STS

Benefits
of a Container Garden

There are countless benefits for having a container garden. The first thing that comes to mind is adding color---glorious color! By adding a spot of color in a beautiful container, one instantly has something special! Add a planted pot to the entrance of your home, create an accent in the garden or brighten a dark/dull spot. Containers filled with color can also draw a guest's eye from an unpleasant view, such as pool or irrigation mechanics. In addition to the obvious beauty they add, container gardens can also be moved around to create different looks and groupings---and highlight a particular plant in full bloom. If you are a renter, container gardening is perfect--it is the way to own a garden that can be moved with you. A container garden can also be helpful to an elder or someone who can't bend down as easily (as we all once could!). There are many practical, really useful applications for container gardening!

It is important to know what you are planting, just as you would when planting a garden. If you want a certain container to be tall, make sure you plant something that grows tall, not necessarily wide. (It may look like it grows tall in the nursery container, but young plants can be deceiving!) This may seem overly simple, but it is amazing how one becomes carried away by a plant in a nursery! By selecting properly you are sure to enjoy the benefits of your container garden.

Factors To Consider...
When planning your container garden, you must think about these things.
1-Light---does the space receive morning sun, afternoon sun, full shade or filtered light
2-Water---how much do you want to water.. do you frequently forget to water? Or travel?
3-Space---what do you want your plant to do (architecturally)--screen, add color, be fragrant, how much space does it have to grow?
4-Cold Hardiness---This is the amount of cold a plant can take. Tropical's will not tolerate freeze, while others require freeze to bloom.
5-Plant Selection---sometimes it is just fine to just have something that makes you happy; but if you are looking to solve a garden problem, then plant selection is key to your success!

Types of Containers
Oh my... there is a wide variety of containers with great availability! Your local nursery probably will have a better product, but these days, Lowe's (we love Lowe's) has a great variety, too. Below are some guidelines Indah Bulan uses to select what type of container should be used for what purpose...
1-Italian Terra-cotta is still the best! It helps the plant breathe, and it prevents root rot... terra-cotta absorbs the moisture from the potting soil. Terra-cotta containers can be painted for even extra color. They patina beautifully, too!
2-Plastic Pots are perfect for dry climates like Los Angeles, Palm Springs, etc.. the plastic holds moisture much better. The down side is that they are plastic... and the plants don't breathe as well and they fade to pink. Plastic has come a LONG way though, and continues to get better.
3-Concrete--is usually used for estates, large gardens, or industrial uses because they are quite heavy and typically ornate. But having one as an accent can be oh so stylish!
4-Wood--is marvelous for natural looking gardens, it breathes well, but it is not permanent, even if treated. These are nice for shady spots, filled with ferns.
5-Ceramic---There are gorgeous glazed planting pots coming from China and South East Asia, the market is flooded with them. Look carefully to make sure there are no cracks! These are fantastic for the colors and how light is reflected... I have fallen in love with these! We use these for water pots, and in sophisticated gardens where we have designed a color theme.
6-Hanging Baskets---These are perfect if space is problem.. there are wonderful wrought iron hooks that are decorative, too! They tend to dry out quickly though, so be prepared to water as needed!
7-Mexican Clay Pots----the biggest mistake made with these affordable containers is planting something that is thirsty. They are not for water loving plants... they are for cactus and succulents, things that are not watered often or at all. (That's why they disintegrate!) They have a wonderful, fun, authentic look though, especially for Spanish architecture and gardens.
8-Wall-Pockets---these can come in all sorts of materials, usually in terra-cotta. They are used to break up a large expanse of wall... and add whimsy to a space.
9-Odd and Ends---Have some fun! What about that rusty old wheel barrow, or gorgeous copper bowl you never use. The weather will eventually deteriorate metal, but by drilling holes for drainage you'll increase the life. There are so many different sculptural elements that can be used for containers... take a look in your garage, or storage shed for something unusual, and place it as an accent or accessory in your garden. It will become a conversation piece for sure! Have some fun... really.. just enjoy yourself!

Types of Plantings
Container Gardens can create divide a space into roomsWhat a broad category... but here are a few tips to decide what type of plants to choose! Once you have decided what kind of plant is for you, remember to buy either sunny or shady plants, depending on your exposure to the sun.

1-Annuals---these are plants that live one season or replaced each year (annually). Petunias, Zinnias, Marigolds, etc... Perfect for a profusion of color. Annuals grow the fastest---if you need something quick, this is your plant. For maximum effect plant a few weeks before you want them to take off! They tend to require lots of watering. Have you ever noticed that they never look as good at home as they do at the home improvement stores? That is because they use Miracle Grow.. or some chemical like that. This is a fertilizer specifically for annuals (although no one ever tells you that!). Basically, this chemical tells the plant.. "don't worry about developing roots, I'll give you all the nutrients you need". The plants are grown in super perfect conditions, and fertilized weekly.. when you stop feeding the plants, they turn yellow, just look awful and then die. You may have a green thumb after all, you simply have chemical addicted plants! Therefore, if you choose annuals, pick up some fertilizer, too! Please, don't use Miracle Grow on anything but Annuals though!!!!! (I wish I had a dollar for every time I have said that!)

2-Perennials---these plants come back year after year. Iris, day-lilies, etc.. These plants usually have wonderful foliage, and will bloom, too. One can mix different heights textures to create mini-landscapes in a pot. They are perfect for those who don't want to replant each season. Water and good potting soil is a requirement. Many plants will need to have the spent flowers removed for ultimate presentation.

3-Shrubs---Shrubs can be deciduous (loose their leaves) or evergreen. Shrubs need at least twice the space to grow as the container they came in... consider how the plant matures (does it grow tall, if so how tall). Planting in a container will limit the size of the plant considerably, but this is good information. Shrubs can be planted in containers for their flower, fragrance or foliage, they also can be an architectural addition to your garden. Imagine a pair of conical (cone-like) plants flanking an English country house. Also, use shurbs in large pots to screen or divide a space into smaller spaces (rooms as we call them). You may want to consider placing these on rollers so you can move them around for a party or just for a change!

4-Trees----Trees can be deciduous or evergreen, too. They can be used to provide some shade, or why not grow an orange tree in a pot (if you have the climate). Purchase large pots for trees to allow them to grow and become a nice size. Place them on rollers, too! In addition, the pot can be planted with other plants that cascade over the side of the container or pot. Select a tree for even more architecture in your container garden, or to provide some shade for a bench or table.

5-Succulents---our favorite! Succulents, are durable... they thrive on neglect, but will show off with attention. There are countless varieties of succulents at your nursery or home improvement stores. Most prefer full sun, but there are some that will take shade. Combine these gems for a fantastic show of contrasting foliage color year-round...and those fantastic blooms will make you want to grab your camera! People generally think of succulents as cactus, and prickly; however, succulents are quite different! If you are not an avid gardener or travel a lot, this group of tough plants is for you!

6-Bulbs and Rhizomes---are seasonal delight! Think Tulips, Jonquils, Paper-whites, the huge Lily family.. oh and Freesia! These darlings of the garden will work in container gardens, too. Planting these treasures deeply in the container with other water loving plants will be a nice surprise for you! At some point they will have to be divided, but for a few years they will just be divine! Play around with color---plant some shocking combinations or similar colors for more elegance.

Types of Gardens

1-Let's start with the front door, the most important element of your home. Having some beautiful specimens of your favorite plant near the front door is just about the best way to say "welcome to my home!". Remember to think about shade or sun though, it is in poor taste to have a dying plant(s) greet your guests. Either plants like sun or they like shade... you can not change that!

2-Have lots of pavement?... add several containers filled with either the same plant lined up geometrically, as we learn from history, to create rhythm and continuity or create groupings of containers to create interesting vignettes. This is a perfect simple solution to softening all that pavement.

3-Patio / Terrace / (Roof-Top Gardens, too). Probably this area, just outside your back door, is a place where your living garden room begins---it is also probably viewed from the den or living area of your home. Create a focal point with one large container, or groupings.. . mix up trees and shrubs, create a space or another outdoor room. What about a water-container garden? One tip is to block a portion of the patio with something large... this will create depth; moreover, if you can see your whole garden from one place, why even go out there. Create some mystery... think secret garden. There are plants for every situation---it's up to you or your design professional to help you put this all together. You can do it though, just think about what you are doing. If a plant dies, replace it with something different! No one is perfect, we all make mistakes! One other important design feature is to consider any existing problems---too much sun? ...plant a tree and position it so that when sitting, you are in the shade or better yet, put it on rollers! Try a deciduous tree (one that looses it's leaves) so you'll have stunning color in the Fall and warmth in the winter

4-Window Box gardening... there are so many fantastic iron window boxes available now with easy installation. This is a happy look for your garden; although it may or may not be appropriate with the architecture of your house. Certainly a bountiful window box is a charming asset.

5-Water Gardens---If you have spent any time at www.IndahBulan.com, you know the IB boys love to use water-pots. They are serene, and create "white-noise" (a constant sound that is soothing to the spirit). The sound of water can also help draw your attention from a bothersome sound (like a busy street). Since the big home improvement stores have come to power, pumps have become quite affordable, and assembly is easy. How about this for a tip... can you hide the fountain in an adjacent garden room, so no one really knows where the white-noise is coming from? Again, think secret garden...

6-Balcony Gardens---this is perhaps the most undeveloped Urban space in big cities. If you're busy, plant succulents! The same philosophy holds true with the other types of gardens... solve problems with your container garden. For instance---too much sun or the view is not the best, plant a vine or a tree. If your balcony is noisy add some white noise (like a water fountain). If your balcony is small, consider using dwarf plant materials. Dwarf plants, are miniature varieties of regular plants; for instance, there is a Nandina (7' tall when mature) and a dwarf Nandina (3' when mature). One must also consider access to water... plant accordingly (see Types of Plants for Ideas).

7-Containers as Accents! Create rhythm and architecture through geometry. Use several small pots together in a shape to delineate a pathway; place a colorful Chinese-glazed pot in a special place in your front garden; break up a long green hedge with a gingerly placed pot planted with something of contrasting color; CREATE SOME DRAMA! This is your opportunity to create a memory... a focal point, something to admire!
 



 

Maintenance

1-The best way to have a garden that is "low-maintenance" is to select the proper plant! If you have a hot sunny spot, you must select a plant that loves full sun. Just because you love petunias does not mean you can make them grow in the shade! This is very important. Planting in the wrong conditions invites disease and the wrong kind of insects. Which translates into buying chemicals to save a hopeless cause. By planting in the proper conditions, you have reduced the maintenance by 80 percent! Plants want to grow, just as we do, so give them the conditions they need to thrive!

2-If purchasing annuals for color, you must fertilize them unless you have started them from seeds. Most all annuals are fed to be enticing at the garden center; after they are in your container for a few weeks, they start to fade---has that ever happened to you? Miracle grow changes the chemical balance of a plant, basically giving it steroids to bloom, without nurturing the root system. When it is not continually fed with this chemical, your plants go through withdrawal, and will die. This just drives us nuts, that no one tells the consumer this! Remember, do not use Miracle Grow on anything but annuals, unless you plan to continually feed it to them for years and years!

3-Water your plants! Although Indah Bulan advocates water-conservation on every level, container gardens are accents by nature, water and enjoy! Select plants with similar water needs, don't plant a cactus (with dry needs) next to an Azalea (which prefers moist soil). Allow your plants to dry out, not bake, then thoroughly water. The amount of times to water will vary from location to location, climate to climate and season to season. Ask your nursery about the water requirements... also ask for plants with the same requirements. (Good Luck at Home Depot!.. (STS laughs)) Select the proper container for your chosen spot, and how much average time you have to water. If you will only water once a week, consider a plastic container---or better yet, succulents!

4-Fertilize or Feed your plants. One way to avoid doing this as often is to replenish the potting soil with a layer of compost, or even trimmings from the plant itself. Talk to your nursery staff about fertilizer for your plants. My father, taught me to use 13-13-13, a good general fertilizer for everything. I use this maybe once a year in the late Winter or early spring, and water thoroughly before fertilization and keep the plant wet for 3-4 days. Don't do this in the heat of summer.

5-Re-pot your container garden every 3-7 years, you're plants will let you know. At the first sign of problems, this usually will help! (Should you have selected a larger container for that plant?)

6-Buy the best potting soil you can afford! The best potting soils will make quite a difference for your plant, because they are properly balanced, and can hold moisture better. You may think you are saving money by buying a cheaper brand, but just don't do it. Make sure it does not have Miracle Grow in it, unless you are planting annuals!

7-Pruning---In college, we were taught, "if you have to prune it, you have planted the wrong plant!". Remember this, it will save you hours of garden work! Ask how the plant you select will grow and don't over plant! Some ornamental pruning is desirable, but it should be a joy, not a chore. Use sharp pruners, and never leave anything you could hang your hat on!This is the most common mistake in pruning, and this action produces often 5 new shoots, which means you are creating even more problems! The general rule is to prune AFTER a plant is finished blooming.

8-Signs of Problems---Your plants will tell you something is wrong... all one has to do is just look at them, and take action at the first signs! Yellow leaves... too much water, not enough Iron; Limp foliage... too much water, not enough sun; brown leaves... not enough water, perhaps too much sun; not flowering... not enough sun; insects... move plant to a different environment; stagnant growth... root bound.

9-Contain that Monster!---by containing the roots of highly invasive plants, like Bamboo and Morning Glory, the garden is safe from an invasion! Go ahead, plant that monster, use a saucer, this prevents the roots from going into the ground. This is a wonderful way to use some beautiful plants that WILL get out of hand given the chance. The container does just that... contain the roots. "It's a good thing!"---thank you, Martha!
