Ideal Soil pH range for Fiddle Leaf Fig
Fiddle leaf fig grows well in the optimal pH range between 5.5-7, and growers must maintain pH around this limit to avoid any adverse effects on its growth and developmental processes.
The pH level of soil can be maintained by the proper addition of organic matter, compost, amendments, and specific strains of rhizospheric plant growth-promoting rhizobacteria (Moustafa 2020).
Fiddle Leaf Fig Soil Requirements
Ficus requires good soil aeration for optimal growth and development, therefore, the use of clayey soil is not a good option for its growth (Adeoluwa et al., 2015).
Do fiddle leaf figs like moist soil?
The growing medium must be well-drained as fiddle leaf fig cannot tolerate standing water conditions. Moreover, the soil must be fast-draining, well-aerated soils, rich in organic matter contents to improve the physical, chemical, and biological properties of soil. You may want to use a moisture meter for better decision-making.
What soil type is best for fiddle leaf fig?
Ficus needs well-drained, organically rich, and loamy soil properly amended with high-quality and safe compost. leaf fig tree survives well in loamy and well-managed soils by adding composting and potting mix.
Organically rich soils will support excellent growth and activities of soil biota that in return improves overall soil health and fertility. Thus, growers can enjoy lush, uniform, and beautiful growth.
Moreover, the use of poultry manure, sawdust, coconut fiber, cow dung, and press mud is also a good approach to maintain good soil fertility (Olivares-Sáenz et al., 2019).
Loamy soil is the best soil for the growth, development, and production of fiddle leaf fig as it allows good retention, and exchange of essential macronutrients, and micronutrients.
Moreover, it offers enough space for aeration, movement of water contents, and activities of soil biota.
Therefore, the plant’s roots can access enough nutrients and moisture contents to support their physiological, and biochemical processes.
Sandy soil causes immediate leaching of nutrients and water contents, and therefore not suitable for most plants. Whereas, clay soil does not offer good aeration and movement of water contents.
Therefore, gardeners should prefer loamy soil for the leaf fig tree.
However, if the availability of loamy is a limiting factor, gardeners can improve the quality and health status of clayey, and sandy soil by the addition of compost, peat soil, muck soil, microorganisms, and potting mix (Hassan et al., 2020).
Fiddle leaf fig Nutrients
Fiddle leaf fig requires a good mix of macronutrients and micronutrients that can support various physiological, and biochemical reactions in the soil.
Usually, fiddle leaf figs have equal, and good requirements of Nitrogen, Phosphorus, and Potassium, and therefore growers must use efficient NPK sources to provide these nutrients (Garrish et al., 2010).
Moreover, maintenance of optimal nitrogen to phosphorus ratio is extremely important for high-quality biomass production. Limited availability of Nitrogen, Phosphorus, Potassium, Calcium, and Magnesium causes reduced dry weight, leaf area, stem diameter, and stunted growth.
So, growers should properly manage the nutritional application to accelerate good growth (Mendoza-Castillo et al., 2019).
Roots of Fiddle leaf fig
Generally, the Ficus genus is a slow rooting plant, and rooting development can be observed within 1-2 months after planting.
1. How many inches of soil the leaf fig tree requires?
Ficus should be carefully planted in pots or containers having an excellent capacity to add at least 4-5 gallons of fast-draining soil. These containers should be filled to ½ or ¼ of their abilities to support good rooting. The soil must be capable of fast drainage to support the maximum growth and production of plants.
2. How to prevent root rot?
There is always a good association between over-irrigation and root rotting, so growers should carefully consider irrigation frequency and scheduling.
Moreover, the presence of soil-borne diseases, insects, salinity, and various other biotic and abiotic stresses can also be a significant reason for root rotting. So, growers should carefully manage all growing conditions to avoid root rotting (Bodah et al., 2017)
Are coffee grounds good for fiddle leaf fig?
Coffee grounds are rich sources of essential macronutrients and micronutrients and can be helpful in improving physical health, chemical reactions, and biological activities in the soil.
Moreover, coffee grounds’ organic nature helps sustain microbial activities, soil biodiversity, water retention, and drainage. Thus, their application helps support optimal plant growth without exerting any adverse effects on growing medium and surrounding conditions. (Iriondo-DeHond, A. 2019).
How do you encourage fiddle leaves to grow?
Proper care, management, right fertilization for provision of fresh nutrients, and irrigation scheduling are all important to maintain the overall growth and development of the fiddle plants.
But fiddle leaf fig leaves can also be stimulated for healthy leaf growth by notching, pinching, and pruning. Usually, plants grow themselves upward to get more sunlight and compete with other plants for sunlight and other resources. However, an acceleration of this process by human can greatly promote fiddle plants’ overall growth.
Pruning is the easiest and reliable way to improve the growth of fiddle fid tree leaves. It involves a specific process of cutting off the fiddle stem to the desired height. Pruning causes activation of dormant buds below the point of cutting and growth-promoting hormones. There is no requirement of adding extra nutrients to support these processes as it may cause nutritional toxicity in the plants and soil. (Wong, M. 2007).
The notching process does not cause the removal of any plant part but instead focuses on notches or small cuts on the trunk to stimulate new growth. This method requires special care and experience, and good results can only be observed with high accuracy and great care.
The pinching process has good similarity to pruning, but it does not require the use of cutters. This method is focused on removing certain stem sections by plucking the top bud or growing the bud from the plant. Pinching can be done by using the pointer finger and thumb for breaking the growing tip. These methods greatly help improve fiddle leaf growth, but growers should also be careful about other growth factors during the summer growth period and other seasonal growing periods (Widmer and Synder, 1957).
How to Feed Fiddle Leaf Figs in Containers?
Growers can fertilize the fiddle leaf figs by the application of organic, inorganic, and liquid fertilizers. Fertilizers can be applied separately, but their application and irrigation water are greatly recommended to get the best result.
The fertilization requirements are greatly dependent on the fertility status of growing media and prevailing environmental conditions. Usually, the nutrients are more soluble and bioavailable in the presence of proper moisture contents and hot climatic conditions. Moreover, nutrient release efficiency from various products and fertilizer sources is also added, so care should be taken before planning fertilizing scheduling (Soutiropolous et al., 2020)
What is the best pot for fiddle leaf fig?
Fiddle leaf fig requires optimal drainage and aeration (oxygen) for survival and maximum production. So, plastic pots are never recommended as they may cause suffocation and adverse effects on root morphology. However, the use of a clay planter or ceramic pots is an excellent approach to get the best results.
Do fiddle leaf figs like small pots?
Fiddle leaf figs should be grown in an average-sized planter. Pots too small will not be enough to support healthy and vigorous growth. Whereas, pots too big, will allow an increase in roots size and length, and a significant portion of energy will be utilized for root growth.
Therefore, growing fiddle leaf figs in a medium-size planter will be ideal. And smaller and larger containers are not recommended.
What brown spots mean on fiddle leaf figs?
One of the most common reasons for brown spots in ficus, in general, is root rotting due to over-irrigation. Irrigation stresses cause significant adverse effects on root structures and root morphology that, in turn, affect the overall growth potential of plants.
Rotting is resulting due to fungal infection and can be prevented by the provision of fast and ample drainage. The appearance of brown spots on ficus should be taken seriously, and preventive measures should be taken timely to avoid further development of the problem (Singh and Bhattacharya, 2020).
