“The hum of bees is the voice of the garden.” –  Elizabeth Lawrence.

1. If you are planning a vacation this summer, prepare your garden for the time you will be away by mulching, watering and putting your planter boxes and hanging baskets in an area that can be easily watered by a neighbor.

2. Remove dead flowers from plants growing in tubs, window boxes and hanging baskets. Deadheading encourages more flowering and keeps displays looking tidy.

3. The leafcutter bee might be found in your roses this time of year. They disfigure rose leaves by making circular holes on the edges. Not to worry. This beneficial bee will go away shortly. For more information on leafcutter bees see http://ipm.ucanr.edu/PMG/GARDEN/PLANTS/INVERT/leafcutbes.html.

4. There is still time to put in a summer vegetable garden. From seed, you can grow bean, chard, pumpkin, radish, snap bean and summer squash. From nursery transplants try growing cucumber, eggplant, melon, pepper and tomato.

5. You can also plant flowering plants that thrive in the heat. Several of these include the canna lily (Canna x generalis), Cosmos, petunias (Petunia hybrida) and zinnia (Ainnia elegans or Zinnia grandiflora).

6. Apply mulch to shrub, perennial and vegetables beds. Doing so will shade the roots and reduce the amount of water the plants will require.

7. Pinch off the faded flowerheads from rhododendrons and azaleas as they finish flowering. Next year’s flowers are formed soon after and will be more impressive if the plants are not spending energy producing seed pods from this year’s flowers.

8. Prune early-flowering shrubs that have finished blooming to encourage the development of young shoots that will bear flowers the following year.

9. Pay particular attention to your citrus trees to keep them clean and fed. For more information on how to fertilize citrus trees see http://ipm.ucanr.edu/PMG/GARDEN/FRUIT/CULTURAL/citfertilization.html.

10. Continue to thin tiny stone fruit (peach, nectarine, apricot and plum) to about four inches between remaining fruit to help trees bear larger, tastier fruit. A fruit tree may drop many immature fruits now; this is simply nature’s way of thinning fruit on trees that set more fruit than they can ripen.
