Q: I have rooted the top of a pineapple. Can you please tell me how to take care of it?

A: Pot the pineapple plant in a 6-inch clay pot, using a standard house plant soil mixture. Give it full sunlight, if possible, or at least very good light. Relative humidity of 30 or 40 per cent is best.Best temperatures for the plant in the home are 75 to 80. Water the plant when the soil starts to feel dry. Good drainage is essential.

Q: I have heard there is a way to prune forsythia every year to assure good growth and plenty of flowers the next year. Can you tell me how to do it?

A: After forsythia finishes blooming in the spring, remove most of the oldest canes, cutting them off at ground level. This will encourage growth of new canes, which will provide flowers next year. Old canes, 4 or 5 years old, bear few flowers so it is best to get rid of them.

It is easy to tell the old canes from the new. The bark of new canes is smooth and bright. As they age, the bark becomes dull in color and often is loosened and flaky.

As the forsythia plant grows, a dense top is fromed that shuts out light and air from the base.Removal of old stems not only encourages growth of new ones but also opens up the top and permits the new canes to get light.

The new canes can grow 5 or 6 feet in their first season. Don't let too many remain. The plant could become too crowded.

Q:Is yellowing and needle-loss in the interior of some fairly dense conifers normal?

A: Needles that do not get adequate light will turn yellow on most conifers and drop. In the forest, branches of pines which are shaded die and drop off. Most conifers lose some of their needles every year.
