Check watering, roots and soil pH before deciding whether to feed the bed. Strawberry chlorosis shows up as a loss of green color. If new leaves turn yellow between green veins, check soil pH and the condition of the roots. This pattern can develop when the plant has trouble taking up iron. If older leaves are mainly affected or the whole plant wilts, start with a different check. Look at where the color changed and how water moves through that part of the bed. Several plants give you more clues than a photograph of one leaf. ## Which leaves turn yellow, and what happens to the veins? Young leaves come from the center of the crown. Older leaves lie farther out and often lower down. Look at new leaves that have already unfolded and compare them with a healthy plant of the same cultivar if possible. Record whether the veins stay green or the leaf turns pale more uniformly. Pay attention to distinct spots, physical damage and differences between plants in one row. - **Yellow tissue between green veins on the youngest leaves.** Check whether the soil pH is too high for strawberries. Examine moisture and root conditions. This pattern is consistent with low iron availability, but it needs confirmation. - **Several older leaves turn pale and growth is weak.** Nitrogen deficiency is one possibility. Check previous applications, drainage and root growth before feeding. - **One old lower leaf turns yellow and new ones stay green.** This can be ordinary leaf aging. Mark the plant and check whether the change spreads to other leaves. - **A whole plant yellows or wilts in a wet area.** Check the root zone. Root damage and diseases can cause this pattern, and the leaves alone cannot reliably distinguish them. Compare a pale leaf that has only just unfolded with a leaf of a similar age from a healthy plant. The color of older leaves can change with weather, age and plant condition. Photograph the plant from above and from the side in daylight, then use the same angle on your next visit. It is easier to tell whether new growth is affected while old leaves continue to change. ## Check water, soil and roots Mark where symptoms are strongest. If one low corner turns yellow after rain, check how long water stays there. If the pattern follows a drip line, inspect whether outlets deliver water evenly. Soil can stay wet under mulch even when the exposed edge has dried. Move some mulch aside and feel the soil near the roots in several places. ### What to record before taking samples - Cultivar, age of the planting and growth stage. - Where the problem started and how the new leaves look. - Recent rain, irrigation, fertilizer, lime or wood ash applications. - Whether new leaves are smaller and whether plants wilt in wet ground. ### Compare two parts of the same bed Start where the plants look normal, then check the affected area. If the lowest part turns yellow after storms, mark the boundary of the wet patch. If some plants are next to working drippers and others next to clogged ones, record the difference before changing the watering schedule for the whole bed. Check the exposed edge as well, where the soil may warm and dry faster. Photographs taken from the same height can make those patterns easier to compare. If plants are stunted and wilting in wet ground, examine the roots of one representative affected plant. Dig it with a root ball and compare it with a healthy example if you have one. Healthy young roots can be pale, while older woody roots are naturally darker. Look for fine feeder roots and check for soft or decayed areas. Rotten roots or a discolored center call for more careful diagnosis. They give you no reason to add fertilizer immediately. If the affected patch grows, several plants collapse or the inside of the crown changes color, prepare photographs and contact a diagnostic laboratory for sampling guidance. Leave healthy plants in place. If the issue began after planting, check the height of the crown and moisture inside the original root ball.

Compare a sample from the affected area with one from a place where the same cultivar grows normally. Keep separate the soils that have different fertilizer or liming histories. If symptoms persist, ask the laboratory which leaves to sample and at what growth stage. Comparing the results can narrow down the cause. Strawberries generally prefer slightly acidic soil. When soil pH is too high, iron can become less available even if the soil contains it. Use the test result and your soil characteristics to decide whether to make a correction. Avoid adding ash, lime or an acidifying amendment based on the color of a leaf. In a Ukrainian garden after prolonged rain or an early thaw, record how long the soil around the roots stayed wet as well. A low spot and a raised bed can behave differently even side by side.

For a new bed, find out where the soil came from and what was mixed into it. In an older bed, look back at watering, previous crop growth and applications. Before sending samples, ask whether to label plants with different symptoms separately. Then you can match the result to a particular group instead of averaging healthy and affected plants. ## What to do before feeding If water is pooling, check where it can drain and whether irrigation is adding water to a zone that is already wet. Where watering looks uneven, inspect individual outlets. Record one change at a time and watch what happens to new leaves. Older damaged leaves may stay yellow, so avoid judging progress from those alone. If several plants keep deteriorating, investigate the cause before adding more nutrients. If testing confirms an iron problem, ask which correction fits the measured pH and the condition of the roots. A compound feed does not replace that decision. If the results show that the bed has a separate need for nutrients and root conditions are now suitable, compare the ingredients and instructions. See [the guide to choosing strawberry fertilizer](https://dunger.ua/en/blog/choosing-strawberry-fertilizer) for what to look up before buying for your own planting. ## Soil feeding for an established strawberry bed  ### [Complex fertilizer fruit crops granular](https://dunger.ua/en/mineral-fertilizers/small-packaging/for-garden-plants/complex-fertilizer-fruit-crops) If the soil and root checks confirm a separate need for compound feeding, look at the granular fruit and berry fertilizer. Its instructions have a strawberry row calculated by area and a soil application method around established plants. Compare the 3 and 4 kg packs using the planted area that needs feeding. This compound does not correct low iron availability or standing water around roots.

Record whether the pattern repeats. One plant is too little evidence to diagnose a nutrient shortage across the bed. If the roots are damaged, find out what is happening below ground before choosing a treatment. ### ### ## Rate this article No ratings yet. Be the first!
