You may think it needs rest but if it is healthy and sending out spikes/buds it does not need rest. As to reptting, go ahead and repot it gently and it may continue to blooming as if nothing has changed. If I were you I would not change its location or culture beyond the repotting. It seems to be thriving.

I have one similar to yours. It was given as a gift years ago and always amazes me at how vigorous it blooms. I am not a fan of leaving old spikes on a Phal and always cut them off when the main, large bloom ends and you are left with a straggly spike. I like to concentrate on growth of leaves over spring/summer to prepare them for their main winter bloom.

However, this one Phal continues to bloom vigorously throughout the summer, making many branches off the main spike so you can't even see the old spike. Usually I cut the spikes down. This year, I moved it out into the yard after the main blooming and today walked around the yard and noticed it was blooming its head off. Also, it has made basil keikis over the last few years which also are blooming. It's starting to look like a bush!

It is obviously some sort of hybrid (who knows whats in it), and I decided tomorrow to cut all the bloom spikes off. Let it rest for a few months and make a new round of spikes this winter. I am in South Florida so it can remain outdoors.

I suspect your plant is similar to mine and you can decide whether to cut off the bloom spikes or just leave it alone.

BTW, I rarely fertilize, this plant is so overgrown its pot that most of the roots are growing outside. I would like to repot it but will probably wait until spring.

Getgoing, I might just repot when I get a chance, I struggle with this one because of the size, and the top heavy spike just makes it a bit awkward to move for a repot. I might have to, though.

Jane, your orchid must be a beauty!

I also cut all my spikes back to the base when I can. Just how I learned, I guess.

As for this one I think you're right that it may be something to do with the kind of hybrid. When I got it, the plant's leaves had purple edging and the backs of the leaves were purple. I know it gets plenty of light, but the purple just gets more intense as it gets older. And the size of this guy just dwarfs other phals I've seen. Between the two characteristics I've been trying to figure out what kind of hybrid it is. It definitely wasn't this big when I got it. The leaves were probably 4 inches long, with huge blooms. Now the leaves have caught up with the blooms and the blooms are a bit bigger. With all the roots overgrowing the planter and huge leaves It's somewhat taken over the table where it lives. Are you saying that it may not be the lamp, it may just be the age?

Bill,

This plant gets about 14 hours of light a day if you count the added time with the lamp. It gets direct sunlight for between 4-8 hours winter/summer in addition to the lamp. The room drops by 10 degrees every night, and varies from a max of 86 on hot days to a max of 70 in the winter, with some winter nights dropping into the 50s. (No efficient heat in that room so I supplement with a ceramic heater).

As for the plant:

This is the total plant in the most recent bloom. It does have a plant spike that was only partially cut as it had a bloom on it, that's since been removed, and this spike died.

That's a close up from one of the first blooms after I got it. It was my very first orchid, and a gift. I'd love to know what it is, (and if I can expect it to get much bigger, ha!)

It also drives me a little crazy that they never seem to sell the grocery store orchids with any information. Some are even improperly potted and rotting when you get them. A store in my area sells miltonias, zygopetalums, and cymbidiums as "exotic" orchids, and their care instructions are totally off.

My own zygo was a rescue from one of these stores, it was potted in 2 inches of potting soil and packing peanuts! I repotted it very quickly into a bark mix and since then it has thrived.

I know so many people who will tell you they can't grow orchids because they got a grocery store orchid, followed the "instructions" and it died. If they had just learned a little orchid culture, done a bit of research, and taken it out of the decorative pot, they would have realized that you just can't pot an orchid like that here.

Where I live it's usually either very cool and humid, or very warm and humid, very often. If you use any medium for orchids that retains a lot of water you have to be really sparing with the water as it just won't dry. I have to stick to just bark and use sphagnum only if I need to save an orchid with few roots left, or I wouldn't be able to grow anything. It's so important to know your plant, AND know your environment. I couldn't grow orchids in Arizona the same way I grow orchids here with a marsh a stone's throw from my front door.

And don't get me started on watering with ice cubes.🤦‍♀️ I'll step off my soap box now.

B I N G O!!! I have your plant in my sun room in bloom right now. I've had it about 3 years and it has not been totally out of bloom a day since I got it. It was a gift to me from a friend who was given the plant while in the hospital. She "just knew" she would kill it immediately, so she gave it to me after it shed most of its blooms. It's still in the grocery store pots, and doing great. I keep waiting for it to take a deep breath and rest for a minute so I can repot it, but it won't.

Confused? Here's why it is so important to know something about the plants you are growing. In my day working in the orchid business, breeders were trying to improve the quantity or quality of the blooms on a plant when they made crosses. In some rare cases they might be trying to make the plants easier to grow, but they thought they were improving the plants by "engineering" their gene pool. Today, breeders are growing or purchasing seedling plants in order to select what they think the general public will "just have to have" blooming in their living rooms. The "not so great" plants are discarded, and the remainder are cloned, which results in hundreds or thousands of that exact plant being available for sale at the same time a few years down the line.

Looking at your photo and my plant, I believe we have clones of plants that were probably pod mates. They bloom with the same pattern (constantly) and although the blooms are not exactly alike, they certainly are close enough to be siblings, and there are probably several hundred copies of each of our plants out there also. My photo is an old bloom, and pretty badly faded. There is another spike with several blooms, but my days as a photo contortionist are about over. and see, you can grow orchids in a plastic pot inside a non draining ceramic pot...Ya just have to be verrrrry careful with the watering. I'll see if I can post a photo.

It does look very similar. And you're right about being very careful about the watering. Unfortunately many don't pay attention and overwater their orchids. Personally I much prefer the looser mediums, they're just easier to avoid overwatering.

This is an old photo of mine, three years ago. My computer bit the dust and had to dig out an old laptop. It will not download the recent photos from my phone.

Interesting all three of these bloomers are shades of yellows. In this photo it has two keikie's. Now I have three basil keikie's, two of which also bloom. You can only imagine the amount of flowers. It is still flowering, but I will cut all the spikes off and give it a break as we enter the fall months.

Bill I tried to answer your message and couldn't. I sent you my email. I would like to respond but can't on this site.

Jane, Beautiful orchid! Now I am wondering if these all have a similar ancestry. The blooms are similar, though I notice that on yours and bill's the aerial roots are far thinner and the leaves far greener and less purple. (The "aerial" roots on mine vary between a standard sharpie and thicker in diameter. Very large and it grows them like crazy). I'd be curious what plant gave the vigorous blooming. Jane, is yours heavy for an orchid? I find that mine is, makes it kind of tough and unweildy to repot.

There is a hybrid called Baldan's Kaleidoscope that was very popular and sold in mass quantities. It looks similar to your plant. It is known for blooming on multiple spikes and more than once a year. I see it has the genetics of 77 other hybrid phals mixing 12 species.

Jane, Have received no email from you. Sent you one I believe yesterday, with two photo attachments. Did you receive that? My e mail is ehney at yahoo.com try me again, will be home most of this pm.

Bill

Bill, I have your email. I will respond tomorrow.
