Madeira-vine prefers a loamy soil texture, which is a balanced combination of sand, silt, and clay. This texture ensures good aeration while retaining necessary moisture and nutrients. Loamy soil also provides a stable structure that supports the vine’s growth, allowing roots to spread easily and anchor the plant firmly. To achieve this, consider mixing equal parts of garden soil, compost, and perlite. This blend will offer the right mix of drainage, aeration, and fertility.
