Saline soils are a major concern when feeding and watering your greenhouse plants. If your plants seem like they are not growing or thriving the way they should, saline may be the culprit. One way to identify high saline presence in your soil is if the tips of your plants have turned brown.
You can take various steps to corrected a saline issue. Begin by testing your water to make sure the salt contents are not too high. If your water has safe levels, you should then flush the plant’s soil with fresh water. Salt is generally collected around the bade of the root. Once you have flushed the plant thoroughly, allow the excess water to drive up and look for a white substance in the water rings. If a white substance is observed, there was salt in the soil. In this case, having a quality greenhouse hose will be important. Also, a retractable hose reel will allow gardeners to keep the hose neatly tucked away.
Gardeners can also add gypsum, sulfur, iron sulfate and even a lime sulfur solution to their soil. Adding gypsum to the top layer of your soil will provide noticeable results, quickly. After taking these steps do not fertilize for 10 -14 days, this will allow the plant to absorbed the nutrients you have added to the soil. Please note, if your water had a high saline presence, you may have to flush your plants on a regular basis to prevent the problem from re-occurring.
