Sow hardy an­nu­als

Garden News (UK) - - What To Do This Week -

For some early cut flow­ers next sum­mer, many dif­fer­ent hardy an­nu­als, such as clarkia, lark­spur, cal­en­dula, ammi and nigella, can be sown in au­tumn to pro­duce strong seedlings that will over win­ter. The seed can ei­ther be sown in rows in the gar­den, or I pre­fer to start them off in cell trays in a cold frame or cold green­house. Just two or three seeds per cell will pro­duce a healthy clump of seedlings that can be planted out at a later date.

Keep pick­ing an­nu­als, such as zin­nias and cos­mos, to keep the plants grow­ing and flow­er­ing for a few more weeks. By pre­vent­ing them from se ing seed they’ll con­tinue to pro­duce more flow­ers as long as the weather is mild.

Make a list of bulbs you want to plant for spring flow­ers and get them or­dered or bought as soon as pos­si­ble ready for au­tumn plant­ing.

The seeds of many hardy an­nu­als can be started off now in cell trays in a cold green­house
