Transplanting in the Greenhouse

When I start vegetables or flowers from seed in the greenhouse, I usually start them in trays. After they have grown enough to have a third leaf, I transplant them to cups or sectioned containers to allow them to continue to grow.

This allows them to absorb nutrients from the dirt in the tray, and then they can be moved to another container with fresh nutrients.

You will notice that a few of these tiny plants have a leaf starting to turn yellow. This can happen when they need more nutrients than they are getting or if they are receiving more water than they require.

I prepare new pots with fertilizer-enriched soil in varying sizes. For a flower….they will not bloom until the roots are bound up in the pot. If I plant some in smaller pots, they will get root bound sooner so the blooms come sooner. Once they are blooming I can set them in the garden. I leave some in the larger pots and allow them to bloom later.

I use small plastic spoons to scoop up the plants, keeping the roots intact; then place them in the new pot. This has to be a very gentle process.

Once the plant is placed in the new pot, I water it well. I also transfer some of the soil from the original tray, because it is already moist and will pack well to hold the plant in place as you water.

So, there you have it. How to grow and transplant your spring flowers.
