When To Sow

Though you’re able to also sow in seeds in March ,   late summer or early fall is generally deal to be the best time to sow in snapdragon seeds .

Seeds that are sown in August or in September and overwinter in a greenhouse or cold frame will become great plants and these will typically bloom earlier than those which are inseminate in the fountain , often beginning to bloom in May .

Seeds inseminate in March will typically flower from June through to around September .

1) Source Antirrhinum Seeds

Of of course , you may buy snapdragon seeded player .

However , you might also regard collecting seeds from snapdragon you already have in your garden .

The seeds of most snapdragons will not issue forth true from seed , so seedlings might not originate up to wait like the parent plant .

However , you’re able to have some playfulness key out what does emerge .

2) Sow Snapdragon Seeds

Sow your snapdragon seeds on the top of a seed tray fill with a suitable seed - start up compost or moist yet fine , crumbly and free - draining mix .

iron the seeds in mildly to make certain they are in contact with the grow medium and cover them very lightly with more of the compost .

Water lightly but make certain that spare water can drain away .

you may grade the tray in a greenhouse or on a sunny windowsill .

3) Prick Out Seedlings

Once the seedlings have germinated , have develop their first truthful leave and are large enough to treat , take each one and place it into its own small pot .

“ Do n’t be tempted to graft seedling too ahead of time , ” warn Colin Skelly , a skilled plantsman from Cornwall .

“ The first parting you will see are the seed leaves and draw on the energy in the seminal fluid .

“ The first unfeigned leaves will arrive later and will often look different to the seed leaves . The root organisation will also have commence to develop .

“ The industrial plant can now develop on its own resources and will benefit from its own pot space . ”

Place these in a sheltered spot , or in a glasshouse orcold frameif you have one .

4) Plant Out In Full Sun

Once all risk of frost has pop off in your area , embed out your snapdragon into their terminal grow office in your garden .

This should be done in May or June .

They will do well in well - drain , fertile land in full sun .

you may grow them on in larger containers if you prefer , or if you do not have a desirable space , in a layer or boundary line .
