Dracaena marginata yellowing leaves

Dracaena marginata yellow spots · More Info

Hi there!

So i have this dracaena marginata. Have had it for about three weeks in my livingroom, 2-3 meters from a bright window. It has many Canes and the new shoots/leaves are starting to go yellow. Check out the pic. Anyone had the same and knows what causes it? It is not standing in water but the soil is pretty wet from last watering almost Two weeks ago.

    Thanks! I have not repotted since I bought the plant so it`s in the same soil as it has grown in (I suppose) for a long time.


    The soil is very wet right now but as I said not standing in water (pot has drainage holes). Any fix or will I just have to wait for it to dry?

    Our choice of soil is very important to the health of our plants and to how hard we'll need to work to give our plants the greatest opportunity to realize their genetic potential. Most container soils we purchase in the US are inherently limiting due to excess water retention. While the limitations associated with excess water retention can be dealt with to varying degrees by various methods, it's much better for the plant and makes things much easier for the grower if the grower adopts a medium in which excess water retention isn't inherent. These soils make it much easier for the grower to maintain a healthy root system, without which a healthy plant is little more than a hope. A good medium you can water correctly also turns your nutritional supplementation program from ;little more than guesswork to something you can take and keep tight control of.


    We can talk more about these ideas if you wish, but in the meantime, you might want to read about some Methods to Help You Deal with Excess Water Retention.

    Thanks for your elaborate answer, Al! Appreciate the input. Just read your article on water retention and it's really informing.

    I hope its overwatering thats the problem and it seems probable. Soil is pretty wet only half way down and thats almost two weeks after watering. Soil is most definitely very water retentive combined with the fact that the plant now lives in an Environment where it does not need much water.

    Will give it some time to dry out and then consider some of the ideas you outlined in your article.


    Again, thanks a bunch!

    If you can measure the interval between waterings in weeks instead of days, it's certain a lot of potential is being left on the table in terms of growth and health. I make my soils so plants need water every 3-5 days at the longest.

    I think the information you'll find if you follow this link is actually much more valuable than the information you just read. What you read describes how to ameliorate the effects of too much water retention. The link contained herein will help you understand how to avoid it altogether. Air in the root zone is as important as water. Water uptake, and thus nutrient uptake, is an energy driven process that must occur in the presence of oxygen. Plants use the sun's energy to make the food (sugar) that drives their metabolism. The plant then, at some point in the future, uses oxygen to 'burn' the food to release the energy needed to take up water and the nutrients dissolved in that water. Not enough oxygen = limited root function or even diseases of the root system.


    I hope you find value in the info I just provided. My early growing endeavors ended in abject failure because I didn't understand what I linked you to. For me and many others, understanding how water behaves in soils is what knocked the 'T' off CAN'T.

    Thanks again! Much useful information to take in. Today I went to the local garden outlet and bought ingredients to mix my own, high draining soil. I really never cared much about what kind of soil I use for different kinds of plants but reading your articles has definitely broadened my understanding of its importance. Always learning:)
