We are still preparing to clean our deck to seal it for the first time.
My DH went to Lowes/HD to find plant friendly deck cleaners. He found a
number of options, but none of the plant friendly products stated that
they would remove algae. He believes we have algae on our deck. The
deck is made from pressure treated pine, and it is surrounded by
trailing gardenias, hostas, and nandinas, with a cameila nearby. Can
anyone recommend a cleaner that will not harm the plants, that will
tackle the algae?
If I spot scrub the algae w/ vinegar, but some vinegar seeps into the
soil, will that harm nearby plants?
Probably not if you dilute it with plenty of cold water.. Unless they
are lime loving plants..
That said you could just buy some Citrox which is plant friendly and
designed for cleaning glasshouses etc plenty of algae in there...-) Its
made by Agralan
Although.. if you think about.. Erm.. algae is an algae.. which are a
basic form of plant;-) So anything that is an algicide may not do much
good for plants. Although you could investigate the Algicides from a
good Horticultural supplier.
Try washing up detergent HOT water (from a bucket) and a stiff yard
broom, and some muscle power.. That should do it and the water will have
cooled by the time it hits the plants I would figure..
1) Microbe-Life SBSC (Soy Based Statuary Cleaner). It doesn't specify
use for wood, but I have used it on my deck with decent results. It
comes in a spray bottle, spray it on, wait a few minutes, scrub off.
2) Pond Care Algae Fix. Ignore the label. For decks, mix 1/2 cup (4
ozs) with a gallon of water in a sprayer, then spray that on the
surfaces of your deck that has the algae. Wait a day, then go out and
scrub it off, or use a pressure washer.
