Planting trees. We always recommend staking with 2 posts and a rail
like these. You can buy from us or make your own, but it is the best way of securing them. If you are in a very windy spot use a second cross rail midway between the top and the floor to give the plant more anchorage and reinforce the support posts. To the face of the rail you need to fix rubber tree pads and belts to stop the rail rubbing the trunk and to strap the trunk to. (make sure the nail heads are sunk into the pad so they don't scratch at the bark). Best to do this once you have positioned the plants and it's a good idea to know where you are going to be digging the hole for the plant as you don't want to be digging where you have just banged in the posts. Position the plant upright and fix the pad and belt and you're all but there. The tree usually has a cane or post that that was used to shape the plant, take it out when plant, or if you leave it in for extra support,
regularly check that the ties/bands we use for training them are not getting too tight, they can soon start to strangle the stems. Probably best to cut off any no longer needed once you have staked them in place within your garden.
