Question

Hi,  Could you tell me how I would start a new bush at this time of year? I live in southwestern Connecticut.  

Also I've had a hydrangea bush for over 10 years and it has never bloomed.  I have moved it a couple of times around the yard, but nothing.  It's foliage is wonderful and healthy.  What am I doing wrong?  Can this be propagated at this time of year?

Thank you,

Mary Ellen

Answer
Mary Ellen, the primary reason for hydrangeas or any other flowering bush to not bloom is the soil. Most likely the soil is lacking in phosphorus. This can be remedied by adding a granular fertilizer with a nutrient ratio of 10-20-20. The first number represents the ratio of nitrogen, which promotes green and healthy foliage; the second number is the ratio of phosphorus for blooming; and the third number is the ratio of potassium, which stimulates root growth.

I would also amend the soil with ample organic matter such as compost, aged manure, peat moss, shredded leaves, and dried grass clippings. This supplements improve the tilth of the soil, balance the ph level, and ward off insects and disease. They also provide a constant source of nutrients throughout the growing season.

In regard to propagating, the best and most effective method is with cuttings. Simply cut a tender shoot that is at least six inches long, remove the lower sets of leaves, and dip the cutting in a rooting compound. You can purchase this product at any garden center. Stick the cutting one inch into a good potting mix. Be sure to thoroughly wet the soil prior to planting.

Next, cover the pot with a clear piece of lightweight plastic. Place the pot in indirect sunlight on an east window seal or under fluorescent lighting. After two weeks, check to see if the plant has rooted by slightly pulling on the stem. If you feel resistance, remove the plastic covering and be sure to keep the soil moist. The plant should then be treated as any other seedling.

Given the time of year, raise the plant indoors over the winter. Be sure to repot if the plant gets too large. As I indicated earlier, be sure it is receiving adequate light by either placing it near a window facing east or south, or by placing it under a flourescent lighting fixture. Always keep artificial lights 3" from the top of the plant for optimum results.

Good luck, and please write again if I can ever be of assistance.
