Solving Plant Troubles in the Greenhouse

Bed Bug Pesticide :

The warm moist conditions in a greenhouse favor the growth of many pests and diseases as well as your chosen plants. Generally, there are few natural enemies within a greenhouse's closed environment, so organisms, insects and diseases can get out of hand amazingly quickly. You can do a lot to prevent problems before they start or before they get away from you.

The first step is to prevent trouble before it can start. Here are four rules of good hygiene that will go a long way to keeping problems away:

  • Use clean soil. Never bring unsterilized soil into the greenhouse. Buy special composts or potting soils that have been sterilized. If you use your own compost/soil mixture for starting seeds, then sterilize it first, either by solarization or by baking it in an oven for 30 minutes at 180F degrees. This will kill fungus that causes damping off.
  • Keep a clean house. Remove waste and rubbish before it can accumulate. Remove dead leaves, old soil and plants that can hide insects. Wash all pots and germinating trays after they have been used. Disinfect the entire greenhouse once a year, in the down season.
  • Good growing practices. Make sure you have good ventilation -- neither too dry, which encourages spider mites, nor too moist which encourages diseases. Use only clean water, preferably rainwater and water early so none of the foliage is wet overnight. Feed your plants regularly. If you grow in border beds, then sterilize the soil annually.
  • Be aware. Look for signs of trouble regularly. Pay attention to the underside of leaves. Take immediate action if you notice a problem beginning.
Once you do notice any problems with your plants, then it is crucial to tackle the trouble immediately. Follow these steps to eliminate them fast:
  • Try non-chemical ways first. Handpick off caterpillars or leaves with leaf miners. Remove any moldy fruits, leaves or flowers. Make sure your growing practices are top notch. One of the best remedies is a soap spray -- eco-friendly and safe to use. Use traps such as sticky fly paper for flies. Make traps for shelter-seeking insects like earwigs, sow bugs and slugs, and dispose of the trapped insects.
  • Get the correct treatment. If spraying, dusting or fumigating are necessary, make sure the product you choose is recommended for use for the specific plants and for use in an enclosed space. Before you begin, remove any plants on the 'Do Not Spray' list.
  • Follow instructions. Take all safety precautions when handling pesticides or fungicides. These products are designed to kill! Use personal precautions -- rubber gloves, long sleeves and a face mask. Close ventilators before using a smoke. Do not get too close to the plant with aerosols, and keep the spray away from blossoms. If you're using a spray, then thoroughly cover both tops and bottoms of leaves. Wash up well when done.
  • Follow up. Follow the rules set out after you have applied a product. After fumigating, leave the greenhouse locked overnight, then open all ventilators the next day. Wash out your equipment as well as yourself, and store everything in a safe place, labeled and sealed.
Keeping your greenhouse healthy and productive is not a difficult thing, but it does require constant attention. With the steps outlined here, you will be get enjoyment and satisfaction with your under cover growing.
