I plan to cultivate Anthuriums and would like to find out how long it takes for them to flower and get to about 30 cm? Basically, I would like to know the period from planting (seeds) to flowering/selling.
Commercially grown Anthurium are generally propagated from cuttings and grafts.
It is possible to grow from seeds but they do need greenhouse production or be grown in tropical zones.
Grown from seed, it will take 2 to 3 years for flowers to form.
Should I remove brown leaves from the anthurium indoor plant? I have an indoor anthurium plant placed close to a window but not in direct sunshine. Some leaves are browning and one flower has faded. Should I remove them?
Yes, you can use a clean knife or garden snips to trim away the spent material.
Deadheading the plant will help encourage more blooms.
Here is a link with growing information.

I have this plant in a pot outside and it is wonderful. Concern now with the cooler temps in the evening. Should I bring it in the garage for the evenings now and will this plant do well in the house for the winter?
Anthuriums are not winter-hardy and will be killed by frost, so you should bring it indoors in the winter. They are commonly grown as houseplants.

My anthurium if 5 years old. I've kept it upright till now but can no longer find anything that will work. It's been repotted once. As you can see from the photo, it's very heavy. Is there any way to keep it in check without simply repotting it each time?
You plant looks to be a good candidate for pruning.
Use a clean sharp garden snips or cutter.
Start at the top of the plant and work your way around.
Trim any dead or withering leaves away.
Prune back any of the hanging or leaves that are falling over the pot. This will help the plant to stand back up again.
When you are pruning hold the snips so the blade is at a downward angle. You will be leaving the plant stem at an angle encouraging multiple stems to grow from that angle.
The plant will now be in a healing mode. Use a misting bottle to spray the plant so it can soak the water up through the cuts and leaves. Mist the plant so the water forms droplets on the leaves but not dripping from the leaves.

My anthurium plant has grown tall. It's pretty but needs to be fuller. Do I prune it, re-pot it or what? I have the plant in my office with indirect sunlight and fluorescent lighting.
The best way to make your anthurium fuller is to provide it with more light, perhaps by adding an additional light near the plant. Plants grown in low light often become "leggy" or excessively tall. Pruning it back should also help the appearance- you can remove about 1/3 of the plant's size at one time.

What's wrong with my Anthurium plant? It's bulging in the center immensely and looks disgusting!
Compare to some of the Anthurium plants on this site:

It does look strange, but I think it is developing fruits- this means some of the tiny flowers on the spadix (the specialized flower spike) have been pollinated. It may be lopsided because more of the flowers have been pollinated on one side than the other of the spadix.
I have an indoor anthurium that has healthy looking leaves but has not flowered for a few years now. Can I do anything to encourage flowering? Thank you for a lovely site that is so friendly and informative. I have just discovered it and already have read valuable articles on my peach and lemon trees. Kind regards David Wellington, New Zealand Ps can upload a photo it it would help.
It may not be getting enough indirect sunlight. If atmospheric temperatures around the plant are above 90 degrees Fahrenheit or below 55 degrees Fahrenheit, this could discourage flower production. The plant could also be not getting enough humidity inside your house. The anthurium may not be getting enough (or too much) moisture in the soil (without it being too soggy). More likely, you could be giving it too much fertilizer. More fertilizer encourages lush leaf growth, but fewer flowers.
