Yellowing leaves on roses aren't a disease - just add these little things and they'll sprout and bloom

New leaves turning yellow

Some gardeners find that just a few days after buying a new rose, it starts yellowing from the "top" down, mainly the new leaves, while the old leaves are fine

Causes: 1. Overwatering; 2. Iron deficiency

Using the process of elimination, check which cause applies to your rose. Generally, roses bought together with their soil won't immediately develop iron deficiency - chances are you've just been watering too much

Solutions:

1. Reduce watering - only water when the potting soil is dry

2. Water with ferrous sulfate solution, or ferment rice-washing water for 1-2 weeks, dilute with 70% clean water, and pour it into the potting soil - don't pour it on the rose plant itself

Old leaves turning yellow and dropping

When gardeners see leaves this yellow, they panic - what to do? Haha, this is actually unnecessary worry. Your rose isn't sick at all

Cause: Normal metabolism, natural replacement of old and new leaves

Roses grow quickly, with new leaves constantly emerging, so of course the old leaves at the bottom naturally "retire"

Solutions:

Simply remove the old leaves - don't leave them in the pot, to avoid rotting and breeding bacteria that could trigger other diseases

Old leaf tips turning yellow and drying up

If the old leaves aren't entirely yellow but are yellowing and drying from the tips, this isn't natural aging - it's a nutrient deficiency!

Cause: Potassium deficiency

Potassium-deficient roses not only have abnormal leaves, but also show poor overall growth and appear weak. If the potting soil is mostly peat and sand, potassium deficiency is likely

Solutions:

1. Add some leaf mold to increase overall nutrition

2. Water with potassium sulfate solution 1-2 times per month

3. Remove old leaves - don't leave them in the pot, to avoid rotting and breeding bacteria

Leaves turning yellow with bumpy, uneven surfaces

If leaves turn yellow, take on an orange tint, have dark-colored veins, and develop bumpy, uneven surfaces, this also indicates a nutrient deficiency

Cause: Magnesium deficiency, calcium deficiency

Magnesium and calcium deficiencies usually appear together. The rose starts growing poorly or stops growing altogether, then leaves yellow and drop - at this point, blooming is nearly impossible

Solutions:

1. Water with magnesium sulfate solution (dissolved in water at 0.1% concentration)

2. Mix 2-5 grams of bone meal into the potting soil each month; mix in crushed eggshells

3. Soak soybeans in water, ferment for 1-2 weeks, then dilute with water and pour into the potting soil (at 0.2% concentration)

Leaves turning completely yellow

Leaves that were growing vigorously completely lose their green color, even the veins turn yellow, and the yellowed leaves carry a hint of orange and red

Cause: Sulfur deficiency, nitrogen deficiency

Sulfur deficiency usually causes the upper leaves to yellow first, while nitrogen deficiency causes the lower leaves to yellow first. Gardeners can determine which one by the position of the yellowing leaves

Solutions:

1. Check whether the potting soil is loose, and loosen it appropriately

2. Remove yellow leaves and prune weak branches

3. Apply nitrogen fertilizer and urea - use light doses but apply frequently

4. Add manure or soybean cake fertilizer

Leaves curling and turning yellow

Some gardeners grow their roses well, but as time goes on the leaves curl and yellow, and some even have scorched yellow edges, looking as if they've been burned by fire

Cause: 1. Excess fertilizer; 2. Fertilizer burn

If the leaves are still green and glossy but the veins are dark, and pests are ruled out, it's likely excess fertilizer or fertilizer burn. This isn't good either - in severe cases it can burn the rose to death

Some gardeners wonder: I haven't even fertilized, so how could there be fertilizer burn? In some areas, rainfall raises the salinity and alkalinity of the soil, making it impossible for the rose roots to absorb nutrients

Solutions:

1. Stop adding fertilizer. If only a few leaves are curling, water more times to flush out the excess nutrients

2. If using compost, remove some of the fertilizer appropriately

3. For severe excess fertilizer, it's best to replace the soil entirely

4. For fertilizer burn, scrape off the top layer of potting soil, temporarily hold off watering, and water only when the soil is dry. In severe cases, replace the soil entirely

Growing roses isn't actually that hard

Once you master these small details

With a seedling, there's no worry about growth
