Miniature Rose Care Guide
If you are reading this your miniature roses must be doing just fine. They have roots and are now ready to be transplanted to soil. They cannot go directly into the garden because they must first be acclimated to the conditions outside of the culture tube.
There are four things you must keep in mind to make this a success.
- They cannot dry out. This includes both the roots and shoots.
- They need indirect light. Direct light will be too intense and cause heat build up.
- They need room temperatures. Around 22-25 degrees Celsius.
- They need fertilizer to grow.
Begin with potting soil that can be purchased from any garden center. Do not use the soil from your garden. If it is not moist, add water and mix. Be careful not to add too much water. If after mixing the soil and water you squeeze the soil in your hand and little to no water drips through your fingers, there is not too much water. If the soil crumbles when you open your hand, it needs more water.
Place the moist soil into a small pot (10 cm or less). Do not pack the soil in but do fill it up to the rim.
Carefully remove the plant from the tube being careful not to damage the roots. It is much easier to do this if the roots are no more than 3-4 mm in length. (If a little medium remains attached it will not be harmful.)
Create a small depression in the soil by inserting your finger and pulling the soil to one side. Place the rose into the depression and gently push the soil in around the roots. Part of the lower stem can be buried in the soil.
Next, water the rose with a dilute soluble fertilizer solution (20-20-20). Don't add too much. You want just enough to make the soil settle in around the roots.
With this accomplished, the roots will not dry out and you have provided some fertilizer. Next we have to make sure the shoot does not dry out. While the plant was in the tube the humidity was essentially 100%. We need to mimic that same situation and the most basic way to accomplish that is to place the pot into a clear plastic bag. Once in the bag and using your mouth simply blow air into the bag to "puff" it up. Then tie the bag off with either a knot or a twist tie. If the bag touches the plant you will need to find a way to keep the bag off of the leaves. Place the pot in a north facing window or any window that does not get direct sunlight. In about two weeks you should begin seeing development of new leaves. At this time the bag can be removed. Let the rose remain in the pot until at least 10-12 new leaves have formed. At that time the rose can be planted into the garden or left in the pot.
Good luck and thank you for visiting the Biotechnology department at BCIT.
