D.I.Y. or NOT

When it comes to doing something myself; either for the adventure of it, as means to create a healthier product or just save some money, I’m interested. Sometimes my efforts and time prove to be worth it in the short and long term. Other times, things have not gone as smoothly as planned or promised and end up costing me much more in time and money.

Because of these experiences, and what I have seen the average homeowner implement over the years, I’m more than happy to direct my clients on practices and/or projects that would make sense for them to do themselves. In landscaping and landscape construction, this means leaving the initial ground work and design to someone who has either the right conditioned muscles or design or horticultural experience. I believe that I have ‘fixed’ as many D.I.Y. projects for homeowners and property managers as I have implemented anew. Sometimes just having a new perspective by someone, not intimately involved with your site, can help you with the details and the whole picture.

I’m always very careful about asking who was responsible for the existing work, as I know that I am sometimes dealing with embarrassment, pride and even marital conflict. Once I had a very motivated client decide that he would build the 6’ retaining wall that we designed to level his rear yard and provide more space. He was semi-retired and had the time. The wall construction seemed to progress well and then, just needed to be backfilled. He rented a machine to backfill and compact the wall – himself. The long and the short of it is that the wall blew out with the weight of the machine sending the machine over the wall and into the woods below. I met his wife a few weeks later and inquired about his progress. She just started sobbing.
This is certainly an extreme example but sometimes even a small patio set incorrectly can cause extensive problems later.

So; what is a good DIY project when it comes to your landscape?

Obviously, everyone is capable of planting trees, shrubs, groundcover, perennials or annuals. Just remember that the big stuff always takes longer than you think and, if this is not something you physically do on a regular basis, be ready with the Advil.
Good bed preparation is necessary grunt work. Access to a rototiller may not be available or manageable for the average homeowner.

Assisted DIY Gutter Cleaning

A few Do’s and Don’ts on basic maintenance:
Do:
• Clean your gutters
• Resecure downspouts that may have become detached
• Watch drainage patterns within your yard for possible amendments
• Remove or cultivate excess mulching
• Cut suckering from trees (*make sure your pruners or saw is sharp and sterilized)
• Prune old growth from flowering shrubs (*) Timing is important for both above items.
• Acquire a soil analysis for your beds and turf areas

DON’T:
• Clean second floor gutters without assistance
• Assume that it is necessary to mulch your beds just because everyone else is.
• Use a chainsaw if you are not experienced
• Add chemicals to your yard or plants – in untrained hands, these can lead to deadly personal and environmental hazards

Nothing can help you budget your time and money better than a well thought out design. Even a 1 hour on-site consultation can save you hundreds in possible misplaced plants, structures or drain lines.
Once you have a game plan, or some experience advice, the areas should be tackled according to priority – which is different for everyone.

To get you started and working towards a landscape plan:

DO:
• Create a base sheet of your site or area(s) that you would like to renovate or enhance. Scale this on a piece of paper using a minimum of 1/8” = 1’0” scale. (1/4” = 1’0” is better).
Include:
      o Existing features (patios, walkways, spigots, etc)
      o Existing trees and vegetations (and whether you want them or not)
      o Window heights along our foundation (if this in an area of interest)
      o Storm water patterns/paths
      o Utilities (a call to a utility marking service will identify the main lines)      o Where the sun is at different times of the year (sun set/rise)
      o Views you would like to hide (look from the inside of your home as well)
• Make a list of how you would like to use the space(s) – Entertainment, small parties, play, sports, gardening, etc.

DON’T
• Assume that your plot plan is accurate. For new construction and/or fencing, a site survey is necessary.
• Neglect elevations in relation to your desired and existing structures and or your neighbor’s site

Site mapping is a time and cost saving DIY.
Site analysis and design should be implemented or, at least, consulted on with a professional.
The step-by-step or phased approach will follow in a DIY and assisted schedule.

The 'Game Plan' for a successful DIY or staged project

The ‘Game Plan’ for a successful DIY or staged project

Beware of the “End-of-Season Nursery Sales”

The weather has cooled, after a record hot summer, and what a perfect time to get your yard back in shape.  It’s always the best time to plant (warm soils with cool air) and the nurseries are desperate to reduce their inventory before winter sets in.  The sales are irresistible!

Specimen plants with a canvas of mulch do not 'frame your home or guide you to the front door'

Specimen plants with a canvas of mulch do not ‘frame your home or guide you to the front door’

A confusing, high maintenance bargain.

A confusing, high maintenance bargain.

Nurseries are inspiring places and you can easily lose yourself in the end of season energy and crisp oxygen high.

For some, finding something unique could be the very thing to enhance their; well… “I’m not sure where I’ll put it but “IT’S JUST SO COOL!” 

Remember, plant material is not furniture or accessories.  They are living, growing and sometimes invasive, disease/fungal carrying, damaging long term additions to your real estate.   They are not something you can easily move to a different location or re-cover if you change your mind about their color to coordinate with the new color of your shutters.

Landscape design is most cost effective when considered on paper first.  There are lots of questions to consider that start with your basic premise for wanting plants in the first place and end with how much maintenance you are willing to commit to.  As a rule of thumb; your front plants should frame your home and guide you to the front door.  Flexibility can be used in the rear yard extending the views from the inside – out.

Before our initial meeting we request that the homeowner complete a 5 page questionnaire to help them organize their thoughts, needs and desires, on paper and provide us with the background information we need to guide them in the right direction for their site and personal taste.   Even a one-on-one consultation on site with an experienced professional landscape designer and/or horticulturist could help you avoid costly impulse buying at the nursery this fall.  Yes, nurseries do have horticulturist and, sometimes, landscape designers but remember – they need to move their stock.

As Spring approaches let Petro Design/Build getcreative and design a custom “First Impression” for you…

The new entry seen below practically beckons you to enter.  The doorway is highlighted by beautiful Upright Hornbeams, while the rest of the architecture is softened by the additional plant material.  The previous gravel drive was transformed into a drop-off area for guests.  A garden bench is tucked into the perennial garden for a visitor’s respite.

 

Early Spring in Timonium

Feel, smell and see spring early this year at the Maryland Home and Garden Show. Petro Design/Build has been on the judging panel for over 10 years and, it’s true that the displays ‘just keep getting better and better.’ This years theme is ‘Beautifying your Outdoor Living Space’.  Go to www.mdhomeandgarden.com for dates and times.

Inside Looking Out…

What is your seasonal window view…?

…Spring, Summer, Fall, Winter…

The view to the outside changes dramatically through the seasons.  Are your views taking advantage of what Mother Nature offers every year…?

Extend your residence from the interior to the exterior by properly taking advantage of your viewsheds.  A landscape does not always need to be experienced by exposing oneself to the elements but can be enjoyed through lovely framed “views” from your cozy interior.   Add a focal point , perhaps some lighting, and your views can give you something to look forward to during the short winter days.

Take a glance out your window…walk through your home…sit it in your favorite chair… Are the views to the exterior maximizing their potential…?  Let Petro Design/Build help plan for all seasons!  Contact us  info@petrodesignbuild.com  or  301.249.9000

Lechuza Self Watering Planters

PETRO RECOMMENDED PRODUCT OF THE MONTH: LECHUZA self watering planters

lattice wall with flowers

 

Form meets function in this innovative growing system by LECHUZA. LECHUZA self-watering planters feature a sub-irrigation system that allows appropriate self-watering for up to 12 weeks depending on the plant type, planter size and location. In addition, LECHUZA planters include removable drainage plugs and an interchangeable plant liner to be used indoors or outdoors.

This delightful product includes simple elements such as a water level indicator, a supply shaft to make watering and adding fertilizer quick and easy, and a separator, which forms and separates a water reservoir within the planter. This system makes at home plant care simple and carefree for frequent travelers or those who simply can’t find extra time in the day to exercise their green thumbs.

The secret to LECHUZA planters doesn’t lie solely in the mechanical pieces, but in the plant substrate used in place of soil. The plant substrate, called LECHUZA-PON provides optimum watering and supports root aeration. Nutrients are stored and released only as the plant needs them and unlike soil, LECHUZA-PON does not compress by itself. The mixture is reusable and adjusts ph-value as well.

 

Petro has successfully installed self-watering LECHUNZA planters for multiple residential projects. These planters are high quality, durable products that are UV and frost resistant and will maintain their appearance for years. Below are photos of design projects where we’ve used self-watering planters to provide aesthetically pleasing outdoor accents to private homes.

Benefits of replacing Asphalt with Pervious Pavement

Montgomery County Department of Environmental Protection defines pervious pavement as having more air spaces than regular pavement, allowing water to drain through the surface into the underlying soil. Most paved surfaces are currently impervious, but Environmental Site Design (ESD) efforts including installation of pervious pavement are being required for new development as well as redevelopment of properties in Montgomery County.

Applying ESD techniques such as pervious pavement in place of asphalt will help to reduce runoff and issues with flooding, as well as improve water quality. Replacing asphalt surfaces with pervious pavement can provide other ecological, social, and economic benefits.  Pervious pavement functions to slow water and allow infiltration while filtering stormwater on-site. Adding trees and vegetation in previously paved areas can provide comfortable spaces by reducing urban heat island effects and improving air quality as well as overall human health. Pervious pavements and vegetated areas help to reduce energy costs and add aesthetic appeal to any environment (www.montgomerycountymd.gov).

Petro has worked on several projects utilizing ESD techniques, including pervious pavement. Petro used pervious concrete and vegetation to help alleviate issues with pooling and flooding at a residence in Columbia, Maryland. The photo below shows the pervious concrete next to older standard concrete.

Good Neighbors

Oftentimes the best neighbors are the ones that you get to see when you want to see them and who get to see you when you want them to see you.

Not that we all want to be recluse but, after a long day at work, it would be nice to relax on your deck or patio uninterrupted by a nosey or even gracious neighbor.  Likewise, your neighbors may not want to see you in your back yard either and so, may also be uncomfortable seeing you relaxing in your yard.

Leyland cypress trees were the big victims in this past winter’s snow.  Sure, they grow fast but they grow so fast that they don’t have the time to develop the substantial root system necessary to carry their weight.  This makes them short lived and ineffective as reliable/long-term screening trees. There are better options for evergreen screens or, depending on the height requirements and/or restrictions, consider framed panel screening.

Particularly if you are on an elevated deck, the best screening is something built.  Considering this past heat; maintaining air circulation becomes critical; likewise with fencing.  An open screen not only allows air to flow but becomes a buffer, rather than an obtrusive wall, and therefore considered a ‘good-neighbor’ foil.  In other words, there is no ‘bad’ side to this option.

There are a variety of attractive exterior shade cloths and awnings that will provide screening and shade, while allowing air circulation.  Remote controlled shade cloths can be installed on the tops or sides of trellising depending on the desired protection.

Lattice panels on top of railings can double as trellising for attractive vines in addition to screening. Consider using self-watering planters secured to railings for seasonal color or a place to easily access your herbs!

Good Neighbors remain just that by providing both properties with attractive privacy.
