Can you recommend a good fertilizer?
Anna, Keosauqua, Iowa
Most soils need amendments as well as fertilizer. Sea weed, manure and bonemeal add bio activity to the soil as well as nutrients. Soils that have depleted nitrogen, phosphorus and potash can be replenished quickly with man made fertilizer formulas. When you grow vegetables, you will need higher proportions for the three types. Root vegetables like higher amounts of potash. Leafy veggies need more nitrogen, Fruit veggies like more phosphorus. Bone meal or 5-10-5 will supply needed phosphorus for tomatoes, peppers etc . Lawns and lettuce need more nitrogen from manure or 8-6-2. Beets, carrots and bulbs like 5-10-10. Often times natural phosphorus in the soil can be release by lime or gypsum. I like natural fertilizers because they add texture to the soil.
When is a good time to transplant some hybrid older roses?
Carol, Norwich, CT
Because the ground has yet to freeze, you can move your roses this winter. You will need to cut back to five main stems. I would make ten about two to three feet tall. You can also cut the roots and dig them up bare root. I would also recommend that your new soil include a third aged manure, a third sand and your present soil. You can mound the soil to the edge so that the edge is two inches below the lawn .
