These are my first Adenium seedlings. Do not know a name. Was bought nameless. When should I start repotting them. How big should they be? How much water do they need now? They are in the living room. So day themp is about 21celcius and night about 17. When should I start with fertilizer, and last When should I pinch the top out to get a fuller plant.

Thanks in advance.

We normally repot when they have 4 true leaves. Others will have more answers for you.

Thanks Dutchlady. The biggest ones are now getting the second pair of true leaves. So I guess waiting is in order.

Adeniumgirl, I would leave them in the tray that you have until spring. As Hetty mentions about transplanting when having 4-6 true leaves is what I do, but yours have plenty of growing space between each and could stay in this tray till spring. Try to give them the most sunlight possible (not sure of your climate) and keep w temperatures you stated or higher.
You can give a weak fertilizing at 1/4 strength each time you water. Do not push for growth in foliage at this time. With the seedlings, they can be kept moister than adults. Let top of soil dry and then give a watering. Do those trays have holes in bottom? Definitely need them if they do not.
If as I do having to have my plants inside for winter. Your seedlings will grow, but will take off in the spring and summer when they can be outside in full sun.

Hi Rick.
No my trays do not have holes in the bottom. So I better try to make some. I Only have to be carefull not to hurt them. I am in Holland. So not much sun right now. They are however in a window sill on the southside. So as much light as possible.
Also I Will start Fertilizing them with a weak solution. What should they have most. I guess phosphate?

Adeniumgirl,
Would help if I looked up in left hand corner to view location. Sorry.
Yes, most definitely make holes in trays. If you can sit the seedlings (in tray) on top of another tray with something under it so that if water sits in the tray, it does not wick up into seedlings.
I use a few different fertilizers, 9-3-6 or equivalent, have used Cactus 2-7-7 throughout winter, then switched in summer.
Just use something similar. Do not push them now, just keep them active until spring when they can get more sun.
Rick

OK. I have cacti fertilizer. I can give that now for the winter. To keep them growing a bit. Than I switch to an other in spring. I hope i can make some holes in it. It is rather hard plastic. These are trays from Chinese food i did use.

Willeke,
Try using a metal screwer heated on stove element and it should melt a hole. Keep doing this so that you have quite a few holes. Lots is better.
Rick

That I did not think of that. I already did the Same with a needle, but that are such tiny holes. I Will do the Same with the screwer. Good idea.

Thanks Rick.
