Why Do Miltonia Orchid Leaves Turning Yellow

The miltonia orchid plant suffers the effects of improper care more than other species. A few facts about the flower: picky about the place of placement, whimsical, gets sick at the slightest fluctuations in temperature and changes in the direction of lighting.

Why do miltonia leaves turn yellow:

  • Waterlogging;
  • Decay of roots;
  • Water ingress on leaves;
  • Burnout in the sun;

Dangerous sign of yellowing of Miltonia orchid leaves

  • when the middle or top leaf turns yellow;
  • the leaf turns yellow unevenly, a yellow spot forms at the base of the leaf, or there is a strip starting from the stem;
  • upon closer inspection, you can see a dark spot at the place of attachment of the yellowed leaf, but sometimes the place of decay is hidden under the plate of the dying leaf.

Seeing such a yellowing leaf, you need to urgently remove it, clean the rotten area to healthy tissue, dry it thoroughly and disinfect it with a fungicide.

Orchid stem rot develops very quickly, after a couple of days you may lose the flower. It all depends on the degree of damage to the stem by rot, if the tissues are damaged to the central part, then the plant can no longer be saved.

Miltonia leaves turn yellow, mainly due to waterlogging. Water can get on the leaves, flow into the joints, and linger in the substrate. As soon as the root system decays or infects a fungus, echoes of diseases appear on the leaves. Lighting, temperature, humid or dry air, exposure to direct rays can cause local problems – burns, spots, yellowing at the edges – but the spread of yellowness from the base indicates the death of the roots.

How to properly care for miltonia at home:

  • Create diffused lighting for miltonia. Place near the window, but not on the windowsill. Shade in the summer or use diffuse grilles on the windows. See if it revived the leaves.
  • In the summer, watch the thermometer – above +20 ° C is already too much for the plant. In winter, the temperature does not drop below +18 ° C. Temperature jumps rarely give an instant yellowing, but against the background of other problems they may well become a catalyst for change. An oscillation of 3 ° is acceptable.
  • Air humidity in summer is from 65% to 70%, in winter – 60%. A decrease in humidity slows down growth, causes a feeling of dryness in Miltonia, which means that the peduncles and leaves begin to die. When humidity rises rapidly, root rot can develop.

You can prevent the appearance of yellow leaves by constant correct watering. Do not over-moisten the soil – the plant does not tolerate excess moisture in the substrate. It is better to spray the air than to pour water again, and even more so to leave the drained liquid in the pan. To prevent root decay when waterlogged, drain the water, dry the pot, do not water for a while, then add in small portions. Use soft water. Water Miltonia in the morning. In summer – early in the morning, without directing a stream of water into the leaf axils and onto the leaves themselves.

Correct Watering Of Miltonia At Home

The basic rule of watering for miltonia is less is more.

How often to moisturize Orchids: in summer, once every 3 days, in other periods – once a week.

The miltonia soil mixture should have enough absorbent, loosening components that do not retain moisture for a long time. If sphagnum moss is added to the substrate to phalaenopsis to preserve moisture, then miltonia can easily do without this component. Optimal ingredients for miltonia in descending order: bark, crushed roots (fern, etc.), dry peat, styrofoam.
