Deep pots for seedlings


#1

So I started some pecans from seed this year, and rooted some mulberry cuttings (much thanks to those who sent me these). Things actually turned out much better than I expected and I have 15 or so tiny trees now. Pecans are dormant (lost their leaves) and I suspect the mulberries will do the same soon as it is getting cold near the outside wall of the greenhouse. I as thinking of transplanting these and was looking for some advice as to what sort of pots to use.

Right now they all are in 1/2gal milk jugs with top removed and drainage holes. It worked for this first stage, but they are in need of something bigger. I was hoping to find something like the nursery 1gal round plastic pot but twice as tall, so there would be plenty of depth for the roots. However I have not had much luck finding anything like this. I’d like whatever pot to be sturdy enough to last a year or two, but light weight and easy to store (since I don’t know when I will use them again after these trees go in the ground).

Anyone have any recommendations? What do you use and/or recommend for 2nd year trees?

Check this site out and see if you find anything. They have tall tree pots. I have no experience using them though.

I use these type of pots, you’re going to have to bury them in the ground to avoid the roots freezing over winter. The pots will make it through but will start to decay after about 3-4 years, usually the top part of the pot rips away if you try to lift it. I’d recommend over wintering in the ground instead unless you have a specific need to keep them in pots.

Thanks @Susu, those are what I had in mind. Now I just need to figure out which size is right and put in an order.

@ILParadiseFarm burying them is a good idea, but too late for this year, cold/freezing weather is already upon us and they are all still used the the greenhouse, but next year… Part of the reason to keep them in pots is I have yet to find places for them, and it takes quite a bit of prep work to get decent soil at my place. It would be nice to get them outside some next summer, then bring them into shelter again for next winter. Then the following spring plant the hardiest ones in their permanent places.

I bought TP818 pots for pecans from Stuewe earlier this year. From discussion with Wes Rice, TP616 would have worked. I chose the 8 inch pots because I can grow the seedlings to larger size in them. If you look at recent posts on http://northernpecans.blogspot.com/ Bill shows pictures of the pots he is using for seedlings. They appear to be about 4 inches square by 16 inches deep. He probably got them from Stuewe.

Those are TP414, I would bet money on it.

If you start the seeds in a pot, you’ll find you won’t need that large of a pot to transplant them into. I spent a lot of time debating on what size to order. I use TP414 for starting pawpaw seeds because it allows for a deep tap root. If you don’t transplant within a year, the taproot will find it’s way out of the bottom. I use TP812 for those trees whose roots like to spread out a bit, usually 2 growing seasons and they need to be transplanted. I also have CP412CH and CP59R for smaller trees.

If you just need a few pots, look under the special deals section.
