Do I need to give my plant fertilizer? (I currently don't give it any) I am in zone 4. (will post images later, can't rn)

I’m new to dragon fruit planting, and I have two dragon fruit cuttings that I’ve left in a small indoor pot for most of this year. I figure I would move them when they starts to grow. Although they have taken root, they have not grown at all. A few months ago, I moved them to the ground in the front yard. They have still not grown and one of them is slightly yellowed. I live in pretty temperate climate so I don’t think weather should be an issue, but there may be too much direct sun in the summer. Should I move them to a 5 gallon pot? I see these pots a lot in this sub and I’m wondering if that’s the best way to grow dragon fruit or if it actually doesn’t matter if the conditions are right? Anything else I could be doing wrong also?

Today, i saw some these weird white spots on the tips of the dragonfruit. I cut them off, suspecting it was something bad. I also wiped the wounds with alcohol (don't think that helped, since its not a human) and sprayed it with a water/vinegar/dish soap mixture. Is this anything bad? (I have seen a spidermite on it abt a month ago, but haven't seen it since, and i've also seen andts before)

I planted this in Feb of 2024 and I am a little worried that the plant is a little loose/small at the bottom. I live in a very windy country. Do I need to be worried?

Hi idk where to post, but I have recently gotten a dragon fruit plant and was able to get some fruit was already growing, but it's only an inch long white flesh and tasteless. I tried waiting longer to pick the other fruits and same thing. One ended up rotten because I waited to long thinking I was harvesting to soon. I'd appreciate advice. The person I got the plant from mentioned that the fruit never came out right and I wanted to try and grow it myself with the same results as the person I got it from.

"Sweet" okay its sweet, they always test the brix ,but is it DELICIOUS, Is it worth growing? Is it worth the effort , time and space it will take . There are so many varieties that brixed high when those youtubers do a taste test. But i need to know what variety tastes Really really delicious. Please answer from your experience. I don't wanna waste my time and space growing some "meh" tasting variety.😅

I am planning on utilizing what I am calling the "Table Trellis" method. I am doing this because I have a table outside that isn't currently being used and I am WAY too lazy to make a trellis.
Some info: I have a stake inside the pot my DF is in.

Do I have to worry about rodents while using this "Table Trellis" method? I have seen some squirrels scurrying around the yard here and there.

This Is the second time this has happened where parts of my dragonfruit plant turn yellow and clear I've searched on Google but I couldn't find an answer

like the title says, what are these small "sprouts" on my dragonfruit? should i rip them out?

So I planted my dragonfruit from a local nursery about 2 months ago. The top node was only about 10cm when I planted it (a little smaller than the two below) and I assumed it would grow new nodes but it just keeps on growing up. (Also I am calling them nodes as I have no idea what the parts of the dragonfruit are called).

What should I do? Do I clip the top to encourage it to grow from lower points?

I’m located in Darwin Australia, so it is very hot at the moment. I’ve been watering every day and the humid hot raining season should be starting next month.

The fence is 6ft/1.82m for reference.

The two on the left hand side are horizontal and v grafted and they take so long to get fat. The three on the RHS are all CLEF GRAFTED.

I grafted the one on the bottom right a week later than the one on the top left, but as you can see, the cleft grafted one gets fat and send out a new branch already. The v grafted one take forever to show any sign of growth. The one on the middle right was grafted in the evening and was already dehydrated and soft,but it becomes hard and a bit fat the next morning. So from my experience,cleft grafting is the best.

What's you guys opinion on this?

I bought this grafted dragon fruit about four months ago. I took off the pink thing on the top that it would normally come with. then I waited a couple months. And they grew about 3 feet in height, and I was just wondering what variety it could be.
