Plant Secrets Only Gardening Experts Know

Outfitting your sprawling yard or sunlit windowsill with dainty-petaled flowers and plants with verdant leaves is no small task. Home gardeners — novices and veterans alike — frequently resort to extensive measures to coax opulent blooms or plush fruits from their beloved plants, no matter how unconventional. The breadth of such methods includes burying unexpected items in the soil for a flourishing garden or playing music to houseplants to make them thrive.

Yet, the secret to taking your treasured garden from simply subsisting to booming lies not in employing various hacks. Instead, it necessitates centering your energies on getting the basics right. This means balancing the intricate powerplay between sunlight, fertilizer, and water, and tweaking them for the better. Disappointingly, it might take years of muddy toil and calloused hands to glean the necessary knowledge to understand plant speak without guidance. So, to span the gulf, House Digest spoke exclusively to two gardening experts: Marina Olshansky, the face behind vescabotanicals, an LA-based plant delivery and care account, and Jessica Zander, garden coach and founder of You Can Do It Gardening. Here's the scoop on the plant secrets you should know to make your plants thrive like nobody's business.

If you were under the impression that under- or overhead watering were the main scourges ailing your plants, Marina Olshansky has news for you. While you might assume that the water that's safe for your consumption, aka tap water, is safe for your plants, that isn't always the case. "Tap water is filled with chlorine and fluoride, which build up in your plants' soil," Olshansky explained to House Digest. Water softeners may exacerbate the problem if plants aren't repotted regularly, due to salt buildup. This eventually materializes up top in the form of browning foliage and white deposits on the potting mix or outside the container's margins. Calathea, dracaena, and maranta plants often fall victim to such a phenomenon, although most slender-leaved shrubs and carnivorous plants also usually exhibit poor tolerance.

Besides, if your tap water is high in alkalinity, your plants might face trouble taking in essential nutrients, especially nitrates, as mildly acidic substrates are key to adequate absorption. So, how can you make the tap water safe for plants? "Leave your water out in an open container for at least 24 hours," divulges Olshansky, "and those chemicals will turn into a gas and dissipate!" And voila — you're ready to water your plants the next day. Another advantage? "It also ensures your water is at room temperature." This is important, as roots can go into shock from a cold soak, as can leaves.

Although gardeners are repeatedly cautioned against wetting certain plants' foliage, that doesn't imply that leaves shouldn't be cleaned at all — a point that Marina Olshansky makes in House Digest's exclusive interview. As is known, habitual airing out of rooms by opening windows and doors, or running heaters and furnaces on full-blast is an open invitation for dust to come in and settle on our indoor plants. Unfortunately, "When your plants collect dust, it's as if their pores are clogged and they're not able to receive light and humidity as easily," says Olshansky. Gaseous exchanges are hindered, too, when the leafy undersides are dust-coated. And that's on top of the dismal aesthetic a grimy plant creates.

So, what should you do under such circumstances? "Keep your plants happy by wiping them down — using only water on a cloth — once a month!" muses Olshansky. The rag can be switched out for a sponge or even cotton gloves if you're looking for a way to clean your dusty houseplants with a genius hack. Small indoor plants can be dunked and twirled in tepid water and air-dried. However, make sure you carry out the activity first thing in the morning to afford them sufficient dry time. This will ward off pesky insects, too. That being said, make exceptions for hairy succulents, cacti, and African violets — they're best wiped down using a soft-bristled brush. Also, avoid using any commercial leaf-cleaning products, for they may leave your foliage greasy, thereby stunting growth.

"The other really important thing to keep in mind when selecting new plants is to understand what kind of light requirements the plant may have," mentions Jessica Zander in a House Digest exclusive. "For example, for best results, don't plant a Hosta in full sun and a rose in the shade." While it isn't news that plants crave sunlight to photosynthesize and mature, matching their requirements is sometimes a tough call. The plant tags can be equally confusing when you must make sense of instructions like "shade to part sun." Quick tip: The first requirement states their preference while the second, their tolerance. Or, even better, take cues from their nursery location and replicate it in your garden. Remember, plants would rather be placed in spots meeting their light requirements vs. fertility, given the latter's scope for improvement. Otherwise, Zanders cautions they "won't thrive and it can be a waste of money."

To start off, track your yard's sunlight throughout the day, noting the sections that progressively receive intense heat vs. the ones that become shaded. This is important, as most shade-loving plants perform better in afternoon shade than morning cover. As you might've guessed, this isn't a "one and done" process that lasts just 15 minutes, although first focusing on the growth season can ease things significantly. Don't forget to account for trees and shrubs maturing to greater heights, which may leave dappled areas underneath that might not be ideal for certain plants' placement.
