FCSBC have been selling Annual Wildflower Seeds in Swansea or four seasons.
From our experience, they are not easy to grow in Swansea’s wet clay soil. To give yourself the best chance, please consider the following: here are some tips on how to grow them.
Select your sunniest spot; no shade at any time;
The soil must be clean of every weed;
Reduce the fertility by digging out at least the top 6 ins/15 cm;
Rake to a fine tilth so that it looks like the top of a good apple crumble;
Don’t go anywhere near the selected spot with any form of fertiliser;
Sow in May at the maximum rate of 3 grms/sq m.;
Water if it doesn’t rain in the first 7 days; [ha,ha]
Enjoy a glorious sight until September/October, depending on your choice of seeds and the weather;
In November, cut back all the old growth, remove it from the site;
Start again next spring.
Don’t be too disappointed if your wildflowers don’t look like the verges and roundabouts in Swansea. The Council has machines to do the work that you are going to be doing by hand. If in doubt, sow in a large container but still follow the advice above.
If this is all too much, why not come to the Botanical Gardens and enjoy the large wildflower bed we will be sowing on the slope facing the lake? In 2017 it bloomed from June to October with a changing colour palette every month.
But go on, give it a go! It is a very small price to pay for months of colour in your garden.
