🧪 Fertilizing
Like most legumes, the Snail Vine fixes nitrogen in its roots and therefore does not require excessive fertilizer.
Recommended Fertilizers:
- ✅ Flowering plant fertilizer (low in nitrogen, rich in phosphorus and potassium)
- ✅ Recommended ratio: 5-10-5 or similar
- ✅ Organic fertilizers (compost, compost tea)
- ❌ Don't overdo it! Too much nitrogen = many leaves, few flowers
Fertilizing Schedule:
Every 3-4 weeks
(Growth period)
Stop fertilizing
(Plant enters dormancy)
Do not fertilize
(Dormancy period)
