Monthly Gardening Tips - June 2022
Despite having one of the driest springs ever we have also enjoyed a mass of spring colour this year. Here is a lovely and unusual pink Lilac growing in Egham; and a purple one in Kew. (Remove dead flower heads immediately after flowering.)
Spiraea arguta (Bridal bouquet) also flowers on last year’s growth, so clip back by up to a third after flowering to encourage new growth which will flower next May/June. The same applies to the lovely yellow-flowering Phlomis fruticosa, below.
I have spotted some lovely climbing roses in the area - which I share with you. Thanks to the owners too!
Remove dead flowers (unless you allow them to remain and produce hips). The best of next year’s flowers will be produced on all new growth produced this year, so merely gently tie new growth back as it appears, and in December-January it will have ripened enough to tie tightly in without breaking. If you can avoid clutter at the base its likely that new growths will appear.
If you want to rejuvenate your bearded iris, below, do it after flowering, in June. Dig the plants up, select strong rhizomes, break them off from the mother plant, cut the foliage down by at least half, and plant them approx. 30 cms. apart. Don’t bury the rhizomes completely. Water and fertilizer should be added.
If you want thousands of foxgloves allow them to seed after flowering and transplant the resulting seedlings in autumn to their final positions. Foxgloves are usually biennial ie: they grow from seed one year; and flower, seed and die the second year.
Hanging baskets and containers
Ideally these should be planted up between late May and early June. Replace compost every year or so.
‘Dot’ plants are effective for the centre of baskets: Cineraria, small Hebes, Euonymus, Lavender, tuberous Begonias etc., and a wealth of diifferent annuals. Personally I use many mixed trailing Lobelias around the edges of baskets and boxes too, and maybe ivy or grey Helichrysum. Water them well in and put them in the shade for a few days to acclimatise/fill out. Most annuals prefer full sun and will need watering probably twice weekly throughout the summer, and feeding. Good luck.
And finally… I was short of pots this year as a wren built her nest right over the top of my allotment pot stack. What skill! Enjoy your June…
