How lengthy has it been given that we had rain favor this? A lengthy, long time. So lengthy, in truth, I had actually forgained what a considerably rainy winter can carry out for a garden.

You are watching: Why do plants look greener after rain

The advantageous results of this wet winter are in complete watch. Plants look lusher, greener and cleaner than they have actually for fifty percent a decade at least.

When a gardener says, referring to rain, “We really need it,” you have to be a gardener to truly understand also. You can supply 14 inches of water – the amount of rain we have actually got considering that October – with sprinklers or hoses or drip emitters and also your plants would certainly not look as great or be as healthy as as soon as the very same amount of water, in the create of rain, is heaven-sent. This is a great discussion for positioning rain barrels to collect runoff from your roof.

Rainwater collection is not simply about conserving water however about storing up a reserve of high-top quality water for watering also.


Tright here are a number of reasons rainwater is more suitable for plants than tap water, but the most crucial is chemistry. In tap water, chlorine is a essential disinfectant and fluoride is included to prevent cavities (as long as you drink one glass a day).

Nearly all plants, yet, are at risk to chlorine toxicity, normally expressed in charred leaf margins. Indoor plants such as Dracaenas and also spider plants (Chlorophytum comosum), pines, yuccas, and fruit trees, in particular, are topic to fluoride toxicity also, with symptoms ranging from charred, discolored, or spotted leaves to stressed fruit that might become diseased.

Calcium and magnesium make tap water tough and also damaging to pipes, which is occasionally remedied by the addition of sodium as a water softener. But none of these mineral elements – which are a lot less focused in rainwater – do plants much excellent when ceded via a sprinkler device. The white sediment you see on the leaves of your plants is calcium and also magnesium sediment from watering water, and sodium, prefer chlorine, is toxic to plant tproblem.

In addition, sodium that reaches the ground is damaging to soil structure, too. In a fertile garden, soil pposts clump together in useful aggregates. Sodium, but, disperses these aggregates and creates cracks on the soil surchallenge.

Plants look greener after it rains because air is 78 percent nitrogen and also nitrogen, over all other facets, is what makes plants green. Several of this aspect, in its nitprice and ammonium develops, comes dvery own in the rain and is automatically taken in by plants with roots and leaves.


Rainwater additionally contains more oxygen that tap water. You can think your plants are dangerously waterlogged as a result of excessive rain. Yet, whereas waterlogging might carry around anaerobic soil problems and result in root rot if you overwater your plants through tap water, the fact that rainwater is very oxygenated might administer a margin of safety as soon as soil is saturated after a downpour.

Carbon dioxide is likewise carried dvery own to Planet to the advantage of plants as soon as it rains. Carbon dioxide, once it combines with other minerals in the atmosphere, imparts to rainwater an acidic pH. When this acidic rainwater reaches the soil, it helps to release micronutrients such as zinc, manganese, copper and also iron that are essential to plant growth however are largely locked up in our local soil, which commonly registers a neutral to alkaline pH. (Excessive pollutants in the air can produce so-referred to as acid rain, which is harmful to plants, however is even more of an issue in the Northeast than locally.)

Another advantage of rain is that it leaches salts dvery own beyond the root zone. These salts, which are carried in irrigation water, accumulate throughout the soil profile and inhilittle plant growth. When these salts are flumelted via the soil after numerous years of accumulation, as is happening this winter, the result is pronounced and the growth of plants is explosive.

Rain also distinguishes itself by the easy truth that it drops uniformly in the garden. This means that all of the soil is leached so that even the furthest reaches of a plant’s root zone will certainly be bathed and cleansed of salt.

And, of course, rainwater will certainly likewise wash off the mineral deposits, dust and also pollutants that cover the leaves of all our plants, each and also eexceptionally one a survivor of the profoundly anti-hortisocial city environment that we call residence.

The glowing visage of foliage after a rain is not just a beautiful sight to watch but additionally a boon to photosynthesis. The procedure whereby plants revolve water and also carbon dioxide right into carbohydprice, which they then consume as life-sustaining power food, photosynthesis is much more reliable when the light that reaches a plant’s leaves is not filtered by a layer of grit and also grime.

In my very own garden, I have been observing a butterfly bush (Buddleia sp.) for numerous years that had actually yet to develop right into even more than a few stickfavor stems upon which a smattering of foliage can be viewed. “Must be a patch of poor soil,” I muttered to myself.

Suddenly, this winter, sassist butterfly bush has put on even more than 3 feet of lush new growth. I was even more than prepared to revolve it right into comarticle however now can hardly wait to see it bloom.

And my Peruvian lilies (Alstroemeria hybrid), which proliferate to form the timeless no-muss-no-fuss ground cover, are already blooming again, a lot earlier than usual.

For the much better component of a decade, I had been playing via a gerbera daisy (Gerbera jamesonii) that had actually been planted on the edge of a walkway where it could be shown off to ideal advantage. Sad to say, it flowered sporadically and declined in vigor from one year to the next. But after this winter’s rain, it has presented brand-new life, as if just yesterday it was carried home from the nursery.

TIP OF THE WEEKGerbera daisies come from South Africa, a habitat mutual through gazanias and also geraniums. What these plants all have actually in prevalent is a preference for drip as opposed to overhead irrigation. I realize that numerous gazanias and also geraniums are sprinkler irrigated and execute simply fine, but you will certainly increase the size of their flowering display screen, and also their lifeexpectancy by staying clear of fungus disease, if you store their leaves dry — unless the foliar wetting agent is winter rain.

The gerbera daisy is a clumping plant and also deserve to be divided at the root for objectives of propagation. Gerbera daisies may be grown indoors as lengthy as they are exposed to plenty of light and also their crowns, where roots accomplish leaves, execute not touch the soil surface. They grow finest when temperatures continue to be between 40 and also 70 levels and also prosper at room temperature.

When in energetic expansion, fertilize weekly via any type of water soluble flowering plant fertilizer that is diluted to one-fourth of the recommended concentration. For a simple yet arresting table arrangement, cut the heads off gerbera daisies and also float them in a crystal or glass bowl that is half-filled via water
