Don’t despair, if life has conspired against you and you haven’t yet got around to planting your summer pots.
Leaving it late can have its advantages. You’re likely to get bedding bargains in garden centres keen to sell off their summer annuals and you’ll still be able to enjoy pots of colour throughout July and August and even into September if you look after them and choose wisely.
Late-summer blooms such as dahlias and lilies can help make summer containers last into autumn, so consider putting a few of them in to prolong your season.
When choosing bedding, try to avoid plants which have loads of roots sticking out of the bottom of the pot, which indicate the plants have been in there for far too long and can make it tricky to remove the plants from their containers.
Line the base of pots with drainage holes with crocks (bits of broken pot) or some other material, which will allow free drainage because most patio plants won’t enjoy sitting in water and wet roots. I usually use the polystyrene I bought the bedding plants in because it’s lighter than crocks if you are going to be moving the pots around. Then fill the pot with multi-purpose compost to around three-quarters full, adding water-retaining crystals to the mix.
Put your main plant in first, which should be taller than the trailers which go around it and will spill over the side of the pot. The tall plant will form the framework for the rest of the display. Firm it in with more compost. Fill around the edges with smaller plants such as trailing lobelia, bacopa and verbena, adding compost as you go. Often people will use a miniature conifer as the tall aspect of the display, but you can just as easily use upright geraniums or osteospermums in smaller containers or more exotic plants like spiky cordylines or exotic-looking cannas if you have bigger pots and want a more tropical-looking display.
Add granular feed to the compost mix which should keep it going through summer and beyond - there are many formulas on the market, which help reduce the need for feeding the plant with liquid feed throughout the summer. Many composts also contain water-retaining and feeding elements.
Water newly-planted plants in well. If it’s dry, you will need to water the plants every day and in prolonged dry spells, twice a day. Do it early morning or at dusk to reduce evaporation. Remember that the smaller the pot you use, the more watering the plants will need because there will be limited compost to retain moisture. Go for the largest pots you have to help avoid being a slave to the watering can or hosepipe.
