Tips to Grow Flowers in Greenhouse

Posted on: February 13, 2012

A greenhouse is actually a closed ecosystem having glass or plastic surfaces. Fresh plants and flowers which are not in season are grown in greenhouse because greenhouses regulate heat balance, humidity as well as light requirements. For this, you will have to keep in mind certain considerations while building a greenhouse. For example, you must make sure that your greenhouse faces southern part of direction. Some other tips on growing flowers in greenhouse are as follows:

  • First of all, you will have to maintain proper temperature in your greenhouse. Day time temperature should not exceed 90 degrees. To maintain this temperature, you will require having doors and windows in greenhouse so that they can be opened to provide flowers with proper ventilation especially on sunny and hot days.
  • As far as night time temperature is concerned, it should be not less than 50 degrees. You can use a number of ways to maintain night time temperature of greenhouse but it will all depend on area in which your greenhouse is located. One easy method is to fill some 5 gallons bucket with water and place them in greenhouse so that they can collect heat during day. In this way, heat will be retained and greenhouse will remain warm during night. Always place buckets of waters with their lids on them. It is necessary to prevent insects from reproducing in water.
  • For proper air circulation and ventilation, use a circulating fan. Circulating fans can be used even when doors and windows are not open. Air circulation is important to provide as it helps growing plants properly.
  • Make a schedule to water plants and follow this schedule on regular basis. If you have a smaller greenhouse, it would be enough to water plants once a day but in larger area, you will need to water plants more frequently. Also remember that water requirements of plants increase when temperature rises.
  • Tropical plants need humid conditions for their growth. If you have grown tropical flowers in greenhouse, make sure you have provided them with humidity trays. It is very easy to prepare a humidity tray as any plastic tray filled with water and having pebbles in it serves as a humidity tray.
  • Last but not the least; you will need to be careful about fertilizing needs of your plants. You can fertilize your plants with either ½ or ¼ strength water soluble fertilizer. Make sure to fertilize plants on weekly basis.

After following these tips, you will be able to grow varieties of flowers in your greenhouse. Some of the popular flowers which can be grown in greenhouse include poppies, zinnias, marigolds and snapdragons.
