Melting Snow and Molds

OK, it’s going to melt….we hope.  This is when the saturation starts along the exterior walls of the foundation. If the gutters have pulled away from the house it’s only going to get worse.  I don’t know about you, but my mold allergies keep me vigilant year-round for water seapage.  It’s easier to prevent than fix.  I’ve been in many homes where the residents are living with and breathing black mold everyday!!  They just got used to it and yet they only buy organic foods!!!  It’s like my painter telling me his health concerns about lead-based paints and how he takes a meter with him to check the levels before sanding; (which is a important and necessary), but meanwhile, he is puffing on a cigarette!!!

Fortunately, my body tells me when mold is around.  I can feel it immediately.

My mother-in-law died 5 years ago from pulmonary fibrosis.  When she was sick the doctors could not figure out what was wrong with her.  She remembered that in the house she used to play in across the street as a child, every member of that family died from pulmonary fibrosis.  She mentioned this to her doctor who tested her and confirmed that she did, indeed, have the disease.  She and her brother remembered that the house smelled moldy.

Mold spores, when breathed in, remain in your lungs.  Good health and a good dose of anioxidants will prevent illness.  As we age,  our defenses may decrease for a variety of reasons (stress, pesticides in foods, hormone depletion…to name a very few)  This is when the spores can attack.

So, check your gutters, crawl spaces and foundations.  If you suspect mold, don’t disturb it yourself. Call a professional immediately.

Spring Garden Inspirations

Are we ready for spring yet? The good thing about lots of snow and ice is that it does make you appreciate spring even more. I’m planning my garden tours, lectures and articles while sitting by my fire at home.
I just received the latest Maryland House and Garden Pilgrimage Tour schedule. What a great opportunity to see some of the most beautiful homes, estates, historic sites and gardens in the state! My interest is in the details (good and bad) that I gather for lectures and articles. Things like – ‘great ways to deal with drainage and erosion issues…or really bad ways; interesting ways to screen utilities; the use of plant materials in unusual circumstances and the like. Very fun and educational.

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.

Garden Clutter

Oh, it’s been a long winter, as evidenced by the copious amounts of garden ornament and furnishings (often still in the boxes), awaiting warmer temperatures.  Those enticing garden catalogs were hard to resist, as their focus is on wonderful outdoor summer life; something that seemed so far in the future.  The down side to all this early buying is that it was purchased before the garden was designed.  So instead of asking, ‘”How many people do you typically entertain?” or “What sort of play areas and spaces do you want for your children?” our challenge is to make all the styles, colors and themes fit together cohesively in the landscape.  Clutter is confusing and can negatively affect the energy of a space.   In design, it’s truly putting “the cart before the burro”  Style should be determined first.  Traditional, contemporary, arts and crafts, country home, etc. and then the spaces determined by desire and need.  If the client is set on ‘collections’, than vignettes may be the solution to organization and simple hardscape materials to provide a canvas for the ‘stuff’…I mean, ‘ornament’.

Bottom line; start with a theme/style; lay out the desired functional spaces and then coordinate the furnishings and ornament within those defined spaces.  Above all; work with a professional before garden surfing. This is more cost effective, reduces clutter anxiety and ultimately provides positive energy.
