Container GrowingSowingVarieties
Lobelia can be annual or repeated , so there are a range of different type to choose from .
However , no matter which character you opt for , it is potential for you to grow these attractive anthesis plants from cum .
To uprise Lobelia from seed :
I demonstrate each step below , having mature Lobelia ‘ Crystal Palace ’ – a half - audacious annual – using seminal fluid from Thompson & Morgan .
1) Mix The Tiny Seeds With Sand (Optional)
Lobelia seeds are highly small so you may find them challenging to handle .
you could see from the image above just how small these seeds are .
I found that sowing individually is near - out of the question and you will inevitably need to thin out your seedling presently after germination .
To make sowing easy , you could consider mixing the ejaculate with some o.k. horticultural sand .
2) Sow Your Lobelia Seeds
Sow the seed on the airfoil of a seed tray or into pots that have been filled with ejaculate - commence potting mix or a suitable igniter and spare - drain metier made at domicile .
“ I suggest sow in into trays to give you the best probability of even germ distribution , ” articulate Gardening Expert Dan Ori .
“ When cover the seed , I recommend place the seed in the palm of one hand , then placing your other hand on top , slightly tilt your hands and rubbing them together move them across the tray .
“ It ’s exchangeable to how you would spread flour on a Earth’s surface before making pastry and you may then thinly overlay them with compost or vermiculite in the same way . ”
As I was growing a lot of plant all at once in a het propagator , I decided to use a plug planter . you may see the resulting Lobelia wad seedling below .
Remember : if buy the potting mixture , be sure to take a peat - free option .
Cover the seeded player over softly with a niggling of the metier you have chosen and firm it gently into plaza .
It is best , because of the size of the seed , to check that the mass medium is moist before inseminate and to water from below .
3) Grow In A Warm Spot
Lobelia seeds require temperatures between 18 - 24 ° C for germination to take position , so I have found it good to use a heated disseminator – to make certain that you provide the good temperatures .
If you do not have one , a cheery windowsill may serve , but you will see better results if you place some sort of cloche or cover over the top ( I find adhere film work well ) to retain passion .
4) Prick Out Lobelia Seedlings
Once the seedlings are gravid enough to plow , prick out each one and carefully place them into an individual pot fulfill with a peat - free multipurpose potting commixture or homemade equivalent .
“ The beneficial time to prick out is when they have two sets of true leave , ” shares Dan .
“ To avoid damaging the stem , make certain you handle the industrial plant by a leafage as it is easygoing to originate a new leafage than a stem . ”
5) Harden Off & Plant Out
You should keep the potted seedling in a freeze - free location and only plant them out into your garden once all risk of frost has pass and the weather has commence to warm up .
I plant mine out in early May and the works had no trouble establishing itself .
Flowering should begin in other summer and in my case lasted for months – you may see from the image above that the outcome were beautiful and highly rewarding .
