我觉得1.2米那个比较靠谱,这样左右就差不多2.4米的样子,如果是5米的围墙,2棵差不多够了,相信我,60公分 ...

There’s no real correct or incorrect answer to “how far apart should my hedge plants be?”. We highly recommend tighter spacing than those who err on the side of extra width.
The 0.3 rule is a good one. Multiply your desired hedge height by 0.3. This will mean that for a 1m high hedge, each plant will be planted 30cm apart, 1.5m high hedge they will be 45cm apart. There’s nothing stopping you from keeping the spacing close as you go up the scale. It will mean you will have a good, tight, attractive hedge in faster time.
Don’t put your plants in the ground 75cm apart for a 1.5m high hedge. You may regret the time it takes to get your desired look and the gaps at the base won’t add as much value. With the price of a 200mm potted plant running at between $8 and $15 and given the look you’re trying to achieve should add value to your property, skimping on the number of plants (unless it’s an extremely long hedge) is not ideal. Think longer term.
Apart from the look of your hedge you also need to consider root competition when deciding on spacing. The bigger the plant the more extensive the root system, which is part of the reason for wider spacing the higher the hedge. Remember that hedges generally require more feeding (Seaweed solution, liquid and slow realease fertiliser) than stand alone plants because each plant in the line is competing with the next one for available water and nutrients. |
