Planting Silk Trees Is Best Done In A Location That Receives Full Sun, But They Will Tolerate Light Shade. While Light, Well Drained Soil Is Ideal, Silk Trees Will Thrive In A Variety Of Conditions, Even Alkaline Soils Keep Your Silk Trees Watered Throughout The First Two Or Three Seasons Of Growth And Add A Layer Of Mulch Around The Trunk To Aid In Moisture Retention. Once Established, Silk Trees Are Drought Tolerant And Grow Quite Nicely With Very Little Care, But A Bit Of Nurturing Is Required To Get Them Off To A Good Start. Staking Newly Planted Trees Is Advised, Giving Them A Bit Of Extra Support To Stand Up Against The Wind And Weather Until Strong Roots Are Developed.
