How to transplant annual sprouting seeds

The joy of growing annual plants is the hope that next season they might self-seed and give something back for all the attention you gave them. So, while you may be tempted to deadhead your annual flowers to encourage a repeat flourish, it does pay allowing a few plants to go to seed.

Hopefully, they will disperse their future offspring and you'll be rewarded with sprouting seed next year.

In the case of one of my front beds, I planted some Californian poppies Escholzia californica but only one survived and it struggled to do anything. I didn't give it too much attention but it must have dispatched a few seeds as the next year a clump of these grew up in the same position.

This year, they are sprouting seeds everywhere - but only within the one bed.

As you can see, this bed has almost nothing growing in it - apart from the odd weed. The bed next to it is full of these Californian poppies to the point that some will need to be removed if the others are going to have room to grow.

So, what to do with the other seedlings?

Maybe I could transplant them! I guessed that the risk wasn't too great if I failed anyway, as the other sprouting seeds required thinning regardless. So here's what I learnt from the experience;

  • Transplant your seedlings as early as possible - I left these probably a week longer than I ought to. The longer you leave them before transplanting the more comfortable they become in their current surroundings and the less likely they will succeed.
  • Dig up some dirt with the plant - if you just tear the plant up without any soil to cover their roots then you will have just killed your sprouting seed. Dig a generous circumference of soil with the seedling and carry it to it's new location as a surgeon would carry a transplantable heart.

    Most flowering annuals have a main tap root which sources all their nutrients and water requirements. If you disturb this root, the less likely you will be to transplanting it successfully.

  • Expect transplant shock - less than 10 minutes after I had moved all my sprouting seeds they each went into shock and keeled over. This is normal. To make sure the seedling handles the shock and doesn't die there are a couple of things to consider;

    1. Don't transplant your seedlings in the middle of the day - your plant won't be able to survive both the shock and evaporation at the same time.
    2. Water you seedlings in really well - this removes any air pockets left after replanting and gives the plant a ready source of water.
    3. Add some fish emulsion to the water - a liquid fertiliser can really help a plant resist transplant shock.
    4. Water your seedlings every day - at least until they are coping on their own.

  • Use an appropriate pest deterrent - if you're not against using snail and slug pellets then sprinkle these around the base of your transplanted seedlings. Otherwise, use shell grit or copper filings to keep them at bay as they will view your struggling plants as an easy buffet.

This was taken a week ago and over the course of the week I watched them lift themselves up, and then droop again. They'd repeat this every day but eventually the drooping would become less and now they are standing upright and growing just as well as their counterparts in the original bed.

I will show another photo, in a week or two, to display their progress but is appears that they will make it and be a welcome part of my front garden.
