Propagating and Growing Dahlia From Seed

Growing Dahlias from Seed

Christmas in the Spring

Last year was the first year we grew dahlias from seed and I am hooked! This method of dahlia propagation is simple, and creates a great surprise in spring. Why? Dahlia seeds are not trtue to the mother plant, so every seed is a new and unique variation. The only way to get a true replica of your mother plant is to divide the tuber, or take cuttings (Dahlia Propagation Through Cuttings article). You get such a broad and wide range of flowers, it is truly amazing, and you can keep the variations you like, dig up that dahlia tuber, and propagate for more.

The seed method is simple, and the dahlia seeds grow fast. Here is how to propagate dahlias from seed:

  1. Find a pot or seed tray and fill it with a seedling mix or a mix of soil and vermiculite.
  2. Wet the medium and pock holes with a seed planter/dibber that are about 1/2″ deep, and about an inch or so apart.
  3. Place your seeds in the holes and cover with soil mix.
  4. The seeds will germinate in about 2 weeks, but if you apply bottom heat with a seed mat, it will speed up the process (This season mine popped in 7 days).
  5. Water daily, and provide plenty of light, either with a grow light or place in a south facing window.
  6. Soon you will have a whole set of seedlings.
  7. Once they are about 2-3 inches or their leaves are touching, you can move them to small pots (3 inches) and continue to grow.
  8. Before you move the little propagated dahlias to the garden, “harden them off” by exposing them to the outdoors, gradually over a week more and more.
  9. Wait for the fun!

Christmas Cactus Propagation

How to propagate a Christmas Cactus

The Christmas Cactus, aka Schlumbergera, is grown widely and is loved for its beautiful winter blooms.  The plant makes a great holiday gift for friends and family, and propagating this plant can produce beautiful offspring for giving. Propagating Christmas Cactus is easy, and this succulent variety takes readily to new roots.  See the simple instructions below on how to root your Christmas Cactus cuttings.

Rooting Your Christmas Cactus: Step by Step

  1. First off, you will need to take some cuttings from your parent plant.  Simply take some Y-shaped cuttings from any growing tip, and take at least 3 segments.  You can just pinch off your segments.
  2. Although not required, most horticulturists advise letting these cuttings sit for 1-2 days is a cool, shady place to let the ends callous over.  This can protect the end, prevent rotting and also increase propagation success.
  3. While your cuttings are sitting, prepare a home for them that includes a mixture of peat and sand.
  4. After your cuttings have waited their proper time, dip the ends in rooting hormone, and stick your cactus into the medium.  You should push them about 1/2 a segment into the potting soil.
  5. Water them sparsely, and in 2-3 weeks you should see new growth at the tip.
That’s it!  After about six weeks, transplant your cacti into its final home and watch it grow.  
Dahlia Cuttings from a Tuber

Propagating Dahlias

Cuttings and Dividing Tubers: Dahlia Propagation

Starting to propagate my dahlias this week, and using a couple of techniques.  In this article i will outline how I am taking tuber cuttings to multiply my stock.  First off, at the beginning of my season, i put my tubers into containers indoors, and cover them about half-way with potting soil so i can catch all the action.  Depending on the type, and the warmth, it usually takes a few weeks before the eyes start sprouting, and another one or two before i can start propagating the dahlias.  Below is an overview of the technique:
  1.  Once the tuber has a number of sprouts, I select ones that are 3 or 4 inches in height for my cuttings.

    2.  Once I have selected a Dahlia shoot with two sets of leaves, I then use a sharp instrument (Exacto Knife), to take a cutting.  Note: You want to get a bit of the dahlia tuber at the base to insure the best chances for rooting.

    3.  I take off the bottom set of leaves once I have the cutting.

    4.  This step is optional, but if you have rooting hormone, it can aid in getting the dahlia cutting to root more quickly.

    5.  Finally, take your cutting and place it in a mix of soil and vermiculite.  The loose soil will give roots free reign, and encourage growth.  Note: I also apply bottom heat and cover the cuttings with plastic to create a complete propagation environment.
