New Guinea Impatients; Fertilizer


Question
What fertilizer is best for new guinea impatients and more blooms?

Answer
Debbie, as with all flowers, you want to use a fertilizer high in phosphorus and low in nitrogen. The ideal NPK ratio is 5-20-10 with the first number representing the percentage of nitrogen; the second number the percentage of phosphorus; and the third number the percentage of potassium.

Just as a FYI, nitrogen promotes lush foliage at the expense of blooming. Phosphorus is the primary nutrient for flowering and fruit size on trees and vegetable plants. Potassium builds a strong root system and aids the plant in the absorption of nutrients.

I would stay with a reputable water-soluble brand such as Miracle-Gro or Peter's, but there are many other great varieties that are sold in garden centers and nurseries. Avoid generic brands as I have found they lack the potency needed for strong growth and production.
Finally, apply the product according to the prescribed dilution rate on the package once every 10 days starting 2 weeks after transplanting.

Also, be sure to amend the soil with organic matter such as peat, compost, and aged manure. These materials will provide a constant source of nutrients, balance the ph level of the soil, and improve drainage. I have also found that plants grown in organic soil are much more resistant to disease and pests.

I hope this answered your question. Please write again if I can ever be of assistance.

Regards,

Mike
