Houseplants 101: Care and recommendations

As someone who has 25 houseplants in 350 sqft and many more on the balcony it saddens me to see apartments without greenery. You don’t have to overcrowd your windows like me but some greenery does make a huge difference.

This guide is for those who just want to keep their plants alive. If you are interested in plants as a hobby head over to gardenweb.com and read the numerous and lengthy posts by a user called “tapla”.

Some general points

  • more light is always better than less. If the care tag says low light, all this means is that the plant won’t slowly die in low light. Keep in mind that everything more than a couple feet away from a window would be considered low light. Many plants tolerate full sun, but acclimatize them! My Aloe Vera got sunburnt because I put it in full sun after being in a dark IKEA which is quite ironic.

  • you’re much more likely to kill plants by overwatering instead of underwatering. Never let the plant sit in water and make sure your pot has drainage holes. Water when the top inches of the soil are dry. Remember: When in doubt, don’t water. When watering, saturate the soil completely and let the water drain out.

  • nursery plants have slow release fertilizer but that only lasts for a season max. Get the cheapest liquid fertilizer and fertilize according to the label.

  • it is good practice to flush the soil every once in a while to prevent fertilizer and salt buildup. This will prevent brown tips.

  • Repotting. It has to be done eventually. Either find a friend to do it for you or buy some soil (peat, coconut coir) and something coarse (perlite, lava rock, seramis, pumice etc.) and mix 1:1 to 1:2. Not the ideal soil but it’ll do. Never ever use pure peat, it’s so soggy and water retentive! Roots need air as well as water. Repot in a bigger pot with drainage, remove some of the old soil and don’t be afraid to cut circling, dead and inwards growing roots off.

  • Every kind of work you do on the plant like repotting, pruning etc. do it during the growing season (June, July in the northern hemisphere) when the plant is the strongest.

Recommended plants

ZZ Plant

Probably the easiest plant in existence. It does fine in low light, super resistant to pests, does not need much water. In fact, I let mine dry out entirely. If you like how it looks, get one of them.

Sansevieria

Another super easy plant. Can handle low light; in fact, this thing will survive weeks in complete darkness. Water sparingly, the sansevieria is super prone to root rot. I think it looks very striking. Combine with a white, cylindrical mid-century pot for maximum effect.

Peace Lily

Peace Lilies are recommended everywhere but I wouldn’t consider them very easy since they are very prone to brown tips and refuse to flower sometimes. Also, I don’t find them very pretty. They are available everywhere; however, they are hard to kill and can do with less light. Water a little bit more.

Philodendron scandens

The easiest vining plant along with the pothos. Can handle lower light if you get them unvariegated. Cut back regularly to promote fuller growth and stick the cuttings back into the soil. If you plan to use a container as big as mine, please use an even more porous soil such as the 5-1-1 mix (google it).

Jade plant

This one is super simple with one exception: it needs full sun. If you have a south-facing window, it’ll do great. In low light, the leaves will get huge and mushy and ugly. Water very sparingly; this is a succulent. Prune regularly to encourage branching.

Fiddle Leaf Fig, Ficus Lyrata

This is not a beginner plant but they are everywhere in interior design magazines and websites. It’s the trendiest plant right now so of course I have one. Very finicky, needs lots of light, cannot deal with drought, cannot deal with too much water, the leaves get edema easily, prone to spider mites, fertilizer burn, root congestion, and so on. But it looks super pretty. If you are a beginner, I wouldn’t get a fig already in tree form. They are super expensive and you might kill it. Instead, get a smaller and cheaper one. If you mess up, just get a new one. Learn how to care for it and let it grow tall. When it reaches two-thirds of the desired height, chop the top off and let it branch out. Wait until each branch grows 3 leaves and again cut it back to two; repeat. Do not remove the lower leaves to make it look more like a tree; the plant needs them to thicken its trunk.

Phalaenopsis Orchids

Orchids are actually super easy. Place in medium light, drown the pot in lightly fertilized water for 10 minutes and let it drain. Repeat once a week. The orchid will continue to flower for many months (mine did for 5). Getting it to bloom again is easy as well.

I have many more plants like a coffee arabica, oxalis, calathea, cordyline fructiosa, croton, begonia rex, peperomias, asparagus etc. but this list will do. If you have any further questions, please ask.

Just a heads up to all the pet owners looking to get indoor plants, many of the ones on this list are toxic. Peace lilies are mildly toxic and will cause vomiting. ZZ plants are extremely toxic to touch and can even irritate your skin if handled without gloves. The philodendron, ficus and fiddle leaf fig will cause inflammation and irritation of the mouth and skin as well as gastrointestinal issues. Research your plants before you buy!

Edit: correction that peace lilies aren’t “real” lilies and so do not cause liver failure.

The ASPCA has a pretty comprehensive database here that you can sort alphabetically or by toxicity to a given animal. The Veterinary Support Personnel Network has also compiled a list of non-toxic options here as well.
If you’re looking for specific suggestions, most succulents are safe (except for some aloes and agave plants) and won’t be bothered by pets anyway. If that’s not your style, leafier safe plants include bamboo, ponytail palms, golden palms, ‘money trees,’ and button ferns. Many flowering plants are considered toxic, but you still have some options, including spice orchids, Christmas cactus, and zinnias.
Ultimately, just be sure to double-check that a plant is safe before you bring it home. All it takes is a quick Google search and your furry friend will thank you!

Personally, I have tons of plants and my dog never goes near them. Whenever I bring home a new plant, I spray Bitter Yuck on the floor immediately around it.
I usually only need to spray once. Even after the Bitter Yuck has worn off, my dog understands that I only spray that on things he shouldn’t go near.

Here’s a good Lifehacker article on pet friendly houseplants

Peace Lilies are not lilies, despite the name. They are mildly toxic to pets (vomiting, diarrhea) but cannot cause liver failure or death.

Thanks for the correction.

Sidebar material here OP, well done.
I’ll give a shout out for aloe plants as well. They’re easy to take care of and look interesting, with the added bonus that if you’re a complete idiot like me and frequently get sunburnt you can chop off a leaf and use the gel that comes out as a pain reliever.

I have the opposite problem, my aloe got sunburnt.

Cut off a bit of your finger and rub it on the plant.

That was maybe the funniest thing I have seen all week. Thank you :slight_smile:

Not sure if you’re making a joke, but succulents can get sunburnt!

If you share space with a cat or dog remember to check for toxicity before you bring anything new home. http://lifehacker.com/the-best-low-maintenance-pet-friendly-houseplants-1773512170 I didn’t google them all but peace lilies, sansevieria and fiddle leaf figs and jade plants are toxic to both cats and dogs. I do keep a jade plant and have a cat, but I also have grass and catnip always available so he’s got a salad bar and never gets desperate. http://pistilsnursery.com/pet-safe-indoor-plants/

@Jory
Thanks for this link. As a cat owner, I am always super wary before buying a plant (even though my cat is not really a nibbler) so it’s nice to have someone compile a list like this.

Great post. How do you deal with the effects of the heat pump on indoor plants?

The problem is more the lack of humidity than the heat. Most houseplants are tropical plants and like higher humidity. Use a humidifier to achieve at least 40% humidity, keep the plants away from heat sources, and mist them with distilled water on very dry days.

@Terry
I had a palm tree that seemed impossible to kill. Any care tips for palms? Thanks.

Currently moving my free Spider Plants and Christmas Cactus across the country to come with me, as I love the buggers. Everyone needs greenery!
Just hoping the move doesn’t kill them.
Thanks for the tips, will be saving this post. Especially regarding brown tips; I probably have them in too salty of soil.
