In general, it depends on your location. In the northern hemisphere, the south side gets the bulk of the sun, because the sun is in that half of the sky. But if you are on a hill, or have a hill to the east or west, it can significantly shorten your solar 'day'. Additionally, if you are in an area that tends to get morning fog, east-facing will get less ...

Many houseplants can withstand low light intensity. You can google "houseplant". Some of them can clean the air too, according to a research done by NASA. I have a copy of that research in google doc here. Here is a shortlist of houseplants: Hedera helix English ivy Chlorophytum comosum spider plant Epipiremnum aureum golden pothos Spathiphyllum `...

This is an interesting and very useful question. I have done a quick online search and, besides those you mention, tobacco smoke apparently contains, among others, two substances that are thought to cause cancer, xylene and toluene, and these are absorbed by the plants below (those marked with an asterisk are small ones, suitable for use in apartments, the ...

You can refer to this article, I think it is okay. In my opinion, you changed the water too frequently. You should only change the water if the water is dirty or bad. When you change the water, you should never throw away all the old water, but retain 1/2 of the old water because lucky bamboo plants are sensitive to water quality change. The ultimate ...

The three numbers should represent N-P-K: N for Nitrogen - helps produce more chlorophyll – makes the leaves/lawn look greener P for Phosphorus - promotes root development K for Potassium - helps with winterizing, and drought resistance. Have fun gardening!

If a house plant is in reasonable light then when it is watered it should receive enough so that water comes out the bottom of the pot. If a plant has really dried out then you may need to let it sit in a small amount of water so capillary action can re wet the entire root ball. Normally though you should not let a plant sit in water. Although it varies ...

It looks like a not terribly well Asplenium nidus, common name Birds' Nest Fern. It may be yours is suffering from insufficient light as well as a dry atmosphere, they do like a lot of humidity, so bathrooms and kitchens are often good places for these. In terms of light, bright daylight is best - a little winter sun won't do any harm. Some care ...

Provided that you are feeding the soil/plants the macro and micro nutrients they need there shouldn't be an issue. Epsom salt (1tbsp/gallon) every now and then helps with some of the micro nutrients. Minerals for your plants can be supplemented via plant food, rock dust, azomite or greensand if needed or through the soil/potting mix of the plants unless ...

I agree with the above answer to your question. However, the plant in question (Lucky Bamboo) is not bamboo. It is a dracaena. It is in the same family as the Corn Plant and Marginata. Due to the way that it grows and looks it is called incorrectly called bamboo. Most bamboo which is in the grass family, would not do well sitting in water.

Of course it is difficult to know for sure, but it sounds like your general care is "the right type of thing". Yes only use distilled water. Don't use "any old bottled water", mineral water, well water, or tap water. Rain water is generally considered acceptable but you might to avoid it if you have a lot of pollution in your area. Pollution generally ...

A healthy, mature, Aloe Vera will bloom (flower) when it's ready... Which translates into -- as far as I'm aware you can't "force" an Aloe Vera plant to bloom, it will flower once it reaches maturity (roundabout 4 years old), is in good health and has stored up enough energy to-do-so. Below are some points which will help keep a potted Aloe Vera plant in ...

It's a bromeliad, most likely a member of the Aechmea fasciata cultivar family. They are a large genus of about 200 species and all are epiphytic tank-forming plants mostly with broad rosettes of arching leaves. Bromeliads are long lasting houseplants but once they flower, like the one in the picture,the next thing they do is start dying. If conditions are ...

I have read the original NASA studies and the plant industry has misused the findings to sell more stock. Yes, plants do filter air but only when their metabolism is going at full speed, that means lots of light, lots of air circulation. Outside light levels in the tropics are hundreds to thousands of times more intense than anything inside your car. ...

This is the Prayer plant (Maranta leuconeura), named because the way the leaves fold up at night is reminiscent of hands held together in prayer. This particular plant is M. leuconeura var. erythroneura, which has the prominent red veins and white spine on the leaves shown in your photographs. Care tips: They're native to the tropics so they don't like ...

Too much moisture is not a problem I have and I've never seen moss growing around my peppers. I have the opposite problem! So I looked in "The Edible Pepper Garden" by Rosalind Creasy, which is the better of the two pepper books I have. As well as appendices of problems, it has a reasonable cooking section and a thorough overview of varieties (including ...

It looks like Papaver somniferum, the opium poppy, and as the others answered, those are flower buds. Your plants look very lush!

There are a variety of different jade trees; this includes some with naturally thicker trunks and others which grow thin like vines. So you may be battling against the way the plant grows naturally. Essentially, you may the wrong variety of jade tree for what you are aiming to achieve. If this is the case, I suggest you begin by looking around and ...

It's a Celosia plant. It's also known as a "fire" flower because of its yellow, orange, and red colors. It can come in a couple of other colors. It's a full sun flower that drops its seeds so it can overtake a garden if you don't collect the seeds (or just plant it separately) "so they say". I have planted them successfully with impatiens and they did great.....

She's probably looking for some fiber in her diet. There are special grasses you can get that are good for cats: maybe just grow a little pot of one of those and she'll ignore the other plants. We did that for our cat when she was an indoors cat, and that worked fine. Now, she only knocks down plants when she's being clumsy :)

What kind of succulent? If it's like most succulents, you can absolutely just trim the ends off the plant and it will be fine (and, if you wanted, you could plant those and make new plants to keep or give away). Additionally, many plants will cooperate well with root pruning, like what bonsai growers do. This typically involves taking the plant out of the ...

It looks pretty much like a poppy. Once those flower buds open (which looks like will be happening soon), you can get a definite answer. The flower is usually much more definitive than the vegetative growth. Source: Wikimedia commons

It is a begonia, probably a Rieger begonia. Check this begonia care site for details. Begonias commonly get gray mold (Botrytis). Since this fungus moves from dead tissue into living, pick off any dead flowers or leaves as soon as you can. Try to keep the foliage and flowers dry.

You can grow almost anything in a pot or vase but some of the issues are: if there are no drainage holes in the bottom and you plant in soil there is a risk of root rot. Even if you have a drainage layer and soil separator it is tricky to maintain just the right amount of soil moisture. many plants are quite happy to grow in water. This is easy if there ...

Looks like natural variegation to me...looks like a typical golden pothos (Epipremnum aureum). It's supposed to have these marks. They show up and contrast best with good lighting. Don't worry about this - it's natural, and healthy.

A good (and kind of fun) way to answer this is with Google Earth. If you look up your address, then click the Sun icon, it will allow you to see the sun light based on season and time of day.

What type of orchid is it and what type of potting medium it planted in? If its roots are in bark, I suggest it needs more frequent watering. I water my bark-potted orchids at least once per week, twice if it's hot and dry. In response to your additional information: Phalaenopsis orchids in their natural habitats typically grow in trees or on rocks and ...

Disclaimer: I've never planted a Sempervivum. This is just my guess. From the information about Sempervivum on this page: The hens will die after flowering, but by that time they will have produced numerous chicks or chickens to take their place. Reproduction is normally vegetative by cutting the numerous stolons growing near the main ...

Although I have no experience of this particular variety, I suspect that the main reason why its leaves are yellowing is that it is receiving too much direct light. These plants prefer indirect light. They are fairly tolerant of low-light conditions and the room in which it lives looks light enough for its needs; the light tube is probably doing more harm ...

Summary (or, "But I didn't sign up for the organic chemistry lecture!"): The numbers are the amounts of major plant nutrients. Get a "balanced" (numbers that are close to each other) fertilizer, preferably "with micronutrients". Read the label. Mix and apply as directed.
