Why Do Apple Trees Need Chilling?
If an apple tree doesn’t get enough chill hours, the flower buds may not open at all or they may open late in the spring. Leaf production may also be delayed. Blossoms may also bloom at irregular intervals and, although this might seem beneficial, the longer the bloom time, the increased likelihood that the tree will be exposed to disease. As you may expect then, a lack of chill hours will affect fruit production as well.

How to check if a tree is dead or dying?
If your tree/plant does not leaf out by May 15th, please perform a scratch test by checking for green under the bark, a few inches over the graft. If the scratch test reveals a brown cambium, that means your tree/plant is dead or dying. Watch our video titled Bare Root (Dormant) Warranty on how to perform this simple test. If the scratch test revealed that your plant is dead or dying, pull it from the ground and take pictures of the entire tree/plant, including the roots. Submit your claim & pictures by using the Return an Item tool on our Customer Service page (or email us at [email protected]) no later than June 1st (or June 15th for persimmon trees).

Do apple trees need cold weather?
Although apple-growing in particular is now widespread in many climate zones, nearly all cultivars still require an annual cycle of cold winter weather in order to set blossom and produce fruit each year.
How accurate is tree size?
Because trees are pruned yearly, tree size is not as accurate an indicator of relative vigor as is trunk diameter. However, this trial indicated that trunk diameter and tree height were both significantly affected by rootstock, and these variables were not affected by scion (Table 3). Trunk diameter and tree size were greater for trees on M7A or MM106 than either Mark or P22. For example, mean trunk diameters of M7A or MM106 varied between 2.0–2.2 inches. By contrast, trunk diameter of Mark or P22 was between 0.7–1.5 inches. Burr knots (a swollen mass of gall-like tissue above the graft union) were also prominent on Mark or P22 rootstocks. This physiological disorder results from incompatibility of the scion and rootstock and sometimes causes adventitious root formation.
What cultivars are good for Florida?
Of the 43 cultivars tested, only 'Anna' (Figure 1), 'Dorsett Golden' (Figure 2), and 'TropicSweet' are recommended for Florida. 'Anna' and 'Dorsett Golden' originated in Israel and the Bahamas, respectively. ' TropicSweet' is a relatively new, patented cultivar from the University of Florida breeding program. These cultivars each have a chilling requirement of 250–300 hours. They also require the accumulation of a substantial amount of heat units before trees will bloom in the spring. Consequently, these three cultivars can be grown in Ocala and northward in Florida.
What apples grow well in Florida?
Relatively few cultivars of apples ( Malus domestica L.) can be grown successfully in Florida. Northern apple cultivars such as 'Golden Delicious', 'Red Delicious', 'Gala', or 'Fuji', are not exposed to enough low temperatures during Florida's mild winters. Apple cultivars have what is known as a chilling requirement. The chilling requirement is the amount of cold temperatures during the winter required for normal vegetative and reproductive growth in the spring. The chilling requirement may be determined on the basis of the cumulative number of hours less than or equal to 45°F during the winter. Each hour is referred to a chill unit. There are relatively few apple cultivars with a low enough chilling requirement to be successfully grown in Florida.
Where was the rootstock trial?
A rootstock trial was initiated during January 1988 at the UF/IFAS North Florida Research and Education Center (NFREC) in Monticello, FL. Apple rootstocks included in the trial were Mark, M7A, P22, and MM106. Seedling rootstocks were initially included in the experiment, but were deleted from the study because the scion cultivars were not true to type from the nursery. A summary of rootstock characteristics appears in Table 4.
