Garden Notes for November 2019.
Prepare for the spring by digging and manuring the vegetable patch in November. Remember to keep a 3-year rotation so that potatoes (for example) are not planted in the same area two years running.
Remember to get your tulips planted before the end of the month. Try layer planting of tulips in containers. Do this by planting the later flowering varieties first, cover them with about an inch to 2″ of compost and then plant earlier varieties. A typical 12″ diameter container can take up to 40 bulbs in order to get a good display that lasts several weeks if this technique is used.
Watch out for slugs even as the autumn starts to turn to winter. We usually look out for them in the spring, but they can still do considerable damage shoots of delphiniums and campanulas at this time before the hard frosts start.
If you are planting a new tree, put a mulch mat around it or mulch with garden compost. The tree will root much better.
We have had quite good growing weather, and many of the evergreens and hardy trees will have made lush growth. Where possible prune the excess growth back before the winter storms set in, otherwise they will be vulnerable. The main pruning will still need to be done in the spring.
November is the best month for planting bare root roses.
After the first frost has blackened dahlias, cut the tops back to about 4 – 6″ and lay the stems over the plants for about a week. This allows the tubers to ripen and harden. When the weather is fine, dig them up and turn the plants upside down to allow any moisture to drain off from the hollow stems and crowns. Store them in a frost-free place where it is cool and dry.
If you have a sheltered and well drained plot, now is the time to sow winter broad beans such as Aquadulce. Early broad beans often escape the blackfly attacks on the growth tips of the plant in spring.
Provided the weather is suitable keep digging the ground for good crops next year. Where possible double dig in farm yard manure, or well rotted compost from your own compost bin.
