When to plant tree fern out?

Lanarkshire, Scotland Sco

bought a couple of dicksonia antarctica cheap from B&Q over the winter , they are in my greenhouse no heating but wrapped in fleece . When should i plant them out? They will be going into a raised bed that has about 8 inches of soil and then a anti weed membrane, should i dig down and cut this away?

On plant dicksonia antarctica



Hi, these are quite sensitive plants. I see your pic looks like Glamis which suggests you're north of Dundee. I would keep them inside at least until after easter and then keep an eye on the weather forecast for frost and re-apply the fleece to the tree fern by draping it over the top. The only living part of the tree fern is the crown where the new growth unfurls. The trunk bit is just a conduit and support. Once it is planted out, unless your going to plunge plant it in its pot, you should protect the crown from frost during the winter months using a cage of rabbit wire stuffed full of loose straw.
Hope that helps

I'm pretty sure that Dicksonia Antarctica don't have a deep root system so you should be fine. Just plant up to the soil level of the pot. I also bought 2 bargain tree ferns from B&Q last year and left them sheltered without protection, tut, tut so I will be very lucky if they have not suffered even though I'm on the Isle of Wight. The pots are quite deep, so you may have to cut some of your fleece away, make sure the soil underneath is well drained. You will need to protect your plants and Treeman has suggested a really good way. I also have some photos of my Nottingham garden with fleece covered plants which might give you a helping hand

My 5 ft. tree fern, also a special from B & Q ,is in a large black tub, half sunken into the ground and disguised with bits of tree branches and covered in bark chips.

I moved it on from a smaller pot, which it had filled with root-think- how will it support itself when it gets really tall?-so yes cut away the liner.

Each winter I push handsful of straw onto the crown, fold the fronds over, secure with string, then a couple of layers of fleece. It has come through three winters so far!!

Just to let you know that a tree fern kept in a pot will result in shorter fronds than those planted directly into the ground.
