Скачать или смотреть Why Aren’t My Fig Trees Growing? The Soil & Fertilizer Fix

This video emphasizes that while fig tree growers often focus heavily on fertilizer, soil temperature is actually a far more critical factor in early-season growth. Fig trees become metabolically active only when soil temperatures rise above 50°F, with optimal growth occurring around 78°F. Without warm enough soil, the trees cannot effectively absorb nutrients or water, regardless of how much fertilizer is applied. Ross showcases healthy, fruiting fig trees that had not yet received any fertilizer, highlighting how an unusually warm spring jump-started their development. This demonstrates that heat alone can significantly boost growth in the right conditions.

A plant nerd's guide to fertilizing fig trees: https://www.figboss.com/post/fertiliz...

For fertilizing, a simple, low-maintenance approach is what I recommend: apply a slow-release product like Caliber Coat or Osmocote once at the start of the season. These fertilizers offer balanced nutrition and last for several months. Supplementing with trace minerals such as calcium, magnesium, boron, and silica can help prevent deficiencies, but it isn’t strictly necessary. Proper soil pH—ideally between 6.0 and 7.5—is also essential for nutrient uptake. Finally, promoting microbial life in the soil through compost, mycorrhizae, or biologically active mixes enhances root function and overall plant health, while synthetic fertilizers can disrupt this balance.

Zone 7A - Greater Philadelphia

Intro & fertilizer talk (0:00):
Discusses common overconcern with fertilizer for fig trees and introduces a simple approach.

Focus on soil temperature (0:41):
Explains that soil temperature, not fertilizer, is key to plant growth, especially for figs.

Soil temp benchmarks (1:16):
Notes root activity begins around 45–50°F, with optimal growth at 78°F soil temperature.

Metabolism analogy (1:37):
Compares fig trees’ temperature sensitivity to human metabolic efficiency.

Potted figs growth (2:19):
Potted fig trees growing well despite no fertilizer, thanks to warm spring conditions.

Fruit development (2:39):
Observes early fruit set on most trees due to unseasonably warm weather.

First fertilizer mention (3:33):
Introduces CaliberCote as a slow-release fertilizer applied once per season.

Fertilizer not applied (3:53):
Despite no fertilizer application yet, trees remain healthy and lush.

Heat vs. fertilizer (4:19):
Reiterates that heat is often more crucial than fertilizer for growth.

Micronutrients matter (4:58):
Stresses the importance of covering all nutrients, not just NPK.

Supplemental options (5:49):
Suggests green sand, rock dust, borax, gypsum, etc., for added minerals.

Simple regimen works (7:00):
Emphasizes that minimal fertilizing has still yielded good results for years.

Soil pH importance (7:21):
Ideal pH is 6–7.5; lime or sulfur can adjust levels to prevent deficiencies.

Soil life matters (7:46):
Microbial life boosts nutrient uptake; synthetic fertilizers may harm it.

Add life via compost (8:16):
Recommends products with mycorrhizae or using compost-rich mixes like Promix.

Mushroom compost use (8:42):
Advocates for affordable, local mushroom compost over pricey potting mixes.
