It may feel like the midst of winter but the keen gardener will already be thinking about next years plants! Growing new and exciting perennials from seed has always been a hobby of mine and with a wealth of seed companies and gardeners who sell there surplus seed fresh each year, there is no shortage of varieties of flowering plants to sow.
Seed collection should be carried out all year round, whilst winter and spring may bring less in the way of seed harvests come the Autumn an abundance of fresh seed for sorting and cleaning will soon lay leaner harvests forgotten. Typically it’s Autumn where gardeners are pictured, poised and armed with sharp garden tools ready to cut back perennials that have gone to seed and are beginning to look untidy and unkempt.
Before you reach for your secateurs and wade into the middle of the border to cut back flower florets of the Astrantia or seed heads from the popular ornamental onions – Allium’s. Take a moment to collect a few seeds from your best performing perennials, these seeds can be used to safe guard against losses or to gift/sell to friends and family.
Freshly collected seed from many perennials can be sown immediately often resulting in the best germination rates. Seeds sown in September will germinate very quickly due to the relatively high light levels and warmer evening temperatures than we would expect as we move toward October.
Seeds sown in September will need protection from prolong frost, a max/min thermostatic greenhouse heater will help keep the seeds free from freezing conditions or if your budget isn’t for stretching then lining your greenhouse with bubble wrap and covering your delicate seedlings with frost protection fleece will all help to ward off frozen compost, seedlings roots and shoots.
