Like many other flowering trees in city,silver oak (in picture above) is also at its best these days. The tree is named so because as the wind flows,the leaves show their silvery back. The tree bears tufts of yellow blooms that are mostly borne in its middle. It is very hardy and used for avenue plantation in farm houses. However,it’s prone to attack by white ants and a periodical vigil should be kept to control the insects. The tree is almost pyramid-shaped. In case one feels it has outgrown and needs to be pruned,it can be headed back from the top. It regains its shape in a few days.

Please explain about the right time and procedure to multiply Euphorbia splendense. Can the cuttings be planted directly in beds?

Rajni,Panchkula

The time to multiply Euphorbia is now. You can put it in sand once it is six-inch-long. Keep the centre moist. The plant is very hardy and you can also plant it directly in beds. Only keep a watch that there is no stagnation of water.

How often should I water grapevine? It is bearing many bunches.

The grapevine should be watered at least once a week. As the temperature rises,you can increase the frequency to twice a week.
