Seasoned gardeners will know that autumn is the perfect time to plant perennials but if you’re relatively new to gardening you might be wondering why everyone gets so excited about it so we thought we would share a little insight. 

It’s been a pretty miserable summer and you would be excused for thinking the planting season is over but think again, autumn really is the new early spring and planting now has lots of benefits for both the garden and your pocket!

Warm Soil

The summer months have really warmed up the soil and although the temperature may start to drop it’s the perfect opportunity to plant perennials as their roots love the warmth and moisture the soil still has. If you plant now the roots will continue to grow right up until the ground freezes giving them plenty of time to establish themselves ahead of next spring which means a headstart on growth and a much stronger plant for next season. 

Less Stress for your Perennials

As temperatures drop perennials intelligently switch their focus. They feel less stressed as the hot sun gives way to cooler days and they can concentrate their energy on what’s happening underground rather than what’s going on above. When planting, ensure you add a layer of mulch after the first frost as this gives the roots extra protection. Gardeners World offers some examples of what mulch to use here.

Moisture levels in soil tend to stay pretty consistent as the dry summer soil soaks up autumn rain reaching a level that you can then monitor and water as required. Watering should continue until the first frost… 

Fewer Weeds and Pests

Cooler temperatures mean fewer weeds which means less weeding for gardeners but it also means less competition for perennials as they can absorb all the moisture and nutrients they need. Come the spring your perennials will be much more robust and better equipped to do battle!

Insects and garden pests drop away too giving your newly planted perennials a chance to establish. If they can start the spring pest free it makes life so much easier for you as a gardener.

Achieve Better Performance 

Autumn planting will result in better performance. Some argue that perennials that have started with a cooler growing season perform better in the spring as they have yet to have to negotiate all the stresses of establishing themselves quickly ahead of the summer. If you think about it, it does make sense, warm soil, less weeds, less pests so overall less stress and we all perform better under less stress!

Lawn Care

Don’t forget it’s not only planting that’s important in autumn you need to also consider lawn care. Turf expert Nigel Downs shares his top tips for Autumn lawn care covering everything from Scarification, Aeration, Top Dressing and Overseeding here.

Cut Back Perennials

If your perennials have finished flowering for this year it’s a good idea to cut them back so they can concentrate their energy and prepare for next year. That said, you might want to leave some as food for wildlife, who could possibly take away the landing pad offered by everyone’s favourite Echinacea. The bees just love it!

Why Autumn Is The Perfect Time To Plant Perennials - Autumn Planting

Tidy Up 

Leaves are an obvious one but it’s worth considering a balance. In some areas, yes, but where you have more vigorous plants, it is worth leaving them and letting them natural-mulch, whilst also protecting plants and keeping the weeds down!

And Finally…

We get asked lots of questions so here are a few questions and answers which we hope you find useful:
