Prepare the garden by breaking up the existing soil (use a hoe, spade, or power tiller). Add organic matter such as manure, peat moss or garden compost until the soil is loose and easy to work. Organic ingredients improve drainage, add nutrients and encourage earthworms and other organisms that help keep soil healthy. Give plants an extra boost by adding a granulated starter fertilizer or a balanced all-purpose feed (for example fertilizers labeled 12-12-12).
Check the plant label for suggested spacing. Crowding plants can result in fewer blooms and weak growth as the plants compete for light. Exceptions to this might be regions with a short growing season, shade plantings which tend to grow slower and fill in less quickly, or a need to fill an area with color quickly such as for a special event or if planning to entertain guests outdoors.
Remove the plant from the container. If plants are in a pack, gently squeeze the outside of the individual plant cell while tipping container to the side. If plant doesn’t loosen, continue pressing on the outside of the container while gently grasping the base of the plant and tugging carefully so as not to crush or break the stem until the plant is released. If the plant is in a pot, brace the base of the plant, tip it sideways and tap the outside of the pot to loosen. Rotate the container and continue to tap, loosening the soil until the plant pulls smoothly from the pot.
Dig the hole up to two times larger than the root ball and deep enough that the plant will be at the same level in the ground as the soil level in the container. Grasping the plant at the top of the root ball, use your finger to lightly rake the roots apart. This is especially important if the roots are dense and have filled up the container. Set the plant in the hole.
Push the soil gently around the roots filling in empty space around the root ball. Firm the soil down around the plant by hand, tamping with the flat side of a small trowel, or even by pressing down on the soil by foot. The soil covering the planting hole should be even with the surrounding soil, or up to one inch higher than the top of the root ball. New plantings should be watered daily for a couple of weeks to get them well established.
Vining annuals require vertical space to grow, so provide a trellis, fence, wall or other structure that allows the plant to grow freely and spread.
My celosia quickly dropped and became pale in color, after repotting. What can I do to revive it?
Hi Nickie,
If you have your celosia pot in a full-sun location, temporarily move it to a location where it gets some shade or dappled sun in the afternoon. Celosia love sun, but it sounds like your plant is a little unsettled from the transplanting. Intense sun can be stressful on new plantings whether in the ground or in a pot. A week or so in part-sun will give it a chance to adjust. When it’s looking healthy again, you can gradually move the plant back to full sun. Make sure you’re giving your celosia enough water. The symptoms you describe sound like a combination of too much sun, and not enough water for a newly potted plant.
My neighbour grew a couple of these, very vibrant and yellow, definitely stands out in a crowd! Not being a flower person, I was instantly attracted to this one and your article helped me find out what they were. Thanks for the info!
Hi Riley,
It’s great you were able to identify the plant. Celosias, whether the plumosa or the cristata species, can be real conversation starters in the garden or grown in a container because of their unique forms. Celosia are also available in brilliant shades of pink, red, and orange.
