Perennial Planting Distance

edited June 2023 in Plants
Just bought some garden ready perennials. Should I plant them apart at their final spread distance, for example 24" apart, or closer together to have less bare soil.

Thanks.

    Some perennials get very big, others stay small, so we'd need to know what you bought to be able to advise.

    Are you sure they’re garden ready and the company are not just saying that?
    I’ve bought garden ready and potted them on and on….  They stand a better chance of coping with weather and slugs than when they are small.
    if you really do want to plant them out then plant at the recommended distance so they have room to grow and spread.

    For me "garden ready" would be filling at least a 1 litre pot, preferably bigger (I often grow them on to 2 or even 3 litres for home-grown perennials from seed or divisions), and I'd plant them at the final spacing.

    I tend to plant quite closely to avoid bare patches of soil and weeds.  The good thing about perennials is that you can move them quite easily in autumn or spring and divide them if they’re getting too big for your space. Their growth rate will depend on your soil, aspect and climate, and other factors!

    Fill gaps with annuals until next year when they'll be bigger.

    I plant closer than recommended, but try to mix plants with the same eventual size. I hate empty space, and fill any gaps with annuals.

    I don't like empty ground either, but as far as spacing perennials goes, it's exactly as @Plantminded says - they perform differently depending on your site and conditions. 
    It also depends on the plant itself. I could buy certain plants in spring, in small pots [3 inch] and let them grow on for a month or two to fill the pots, then plant out later in summer.
    That will certainly depend on the type of plant, whereas many others would benefit from potting on again and planting out the following year. As an example, I bought a new Aquilegia last year, and it was treated as I describe - flowering beautifully this year, and has grown a huge amount. Something a little fussier, and less tough, wouldn't have done so well   :)
    It's a place where beautiful isn't enough of a word....

    Having been here as a beginner in the not-too-distant past, I'd personally err on the side of leaving a decent gap between plants and fill the gaps with annuals if you want.

    Some herbaceous plants really do get wider than you initially expected after 2/3 years. If they're particularly happy, well past the estimated width on the labels on occasion.

    Thanks for all the advice. Come up with this compromise in the end, spacing plants at 80% of final size. Using tinfoil rings as a guide to spacing.

    Thanks.

    That's far too many plants for that space.
