griselinia between leylandii

member11809 · Guest

I have just recently planted 4 leylandii which are five feet tall and three feet apart. I want a quick screen and want to put griselinia between them. Can anyone forsee any problems?. Note it is leylandii castlewellan gold which is a bit slower growing

Yes, the Leylandi will smother the Griselinia.

Five feet tall now. You underestimated the spacing by about double. They will want to spread 18" each way every year, and more than that on top. Assuming you want a hedge less than 10' wide and 20' tall, you picked the wrong plant. If you want to keep them, forget any other plants. You will be throwing away money.

Could i plant the griselinia still in pot between the leylandii and move it when the leylandii fills in. Would it grow buried in the pot?. I have seen people doing this

I see you now that want a 1 foot wide hedge. Leylandi is not suitable for a one foot wide hedge.

The leylandii are in. The space is 18 feet long. I want them seven feet high. How wide can they be

Dig up the Leylandi then.

I see you are determined to keep them. Fair enough. They can make great plants, and could make a thick hedge quickly, but I stand by what I said about trying to introduce other plants. They will get outcompeted and die.

I am doubtful about your links recommending "twice a year" though. To keep them that small you'll basically have to treat them like a lawn: every time it grows two inches, trim off one. It will grow inexorably outward and upward. "The golden form of leylandii, Castlewellan, grows slightly slower than the green form (approx 75-80cm per year)". Yes. That is in all directions.

Unfortunately, that means that you won't get the full effect of the golden terminal shoots. Don't be tempted to cut deeper, which you will as it grows. Once you cut too deep and a brown patch appears, it's there forever. It cannot green up again.

My prediction: You are in for several years of backbreaking work every few weeks over the summer months. Your plants will get too big and wide, and start to look a bit scabby as a result of your efforts to tame them and force them to your will. Then you will cut them down, have to replace the soil where they grew, and have to buy something else.

Best of luck! Let us know how you get on.
